3 Points to ponder What are the parts and functions of the urinary system? What is the macroscopic and microscopic structure of the kidney? What are the three processes in urine formation? How is the kidney involved with regulating watersalt and acid-base balance of blood? What are the common disorders of the kidney? How can kidney failure be treated? How is the kidney involved with maintaining homeostasis along with other body systems? 3
4 11.1 Urinary system What are the organs of the urinary system? Kidneys (2) bean-shaped, fist-sized organ where urine is formed Ureters (2) small, muscular tubes that carry urine from the kidneys to the bladder Bladder (1) expandable organ that stores urine until it is expelled from the body Urethra (1) tube (longer in men than women) that carries urine from the bladder to the outside of the body 4
5 11.1 Urinary system Overview of the urinary system Adrenal glands produce aldosterone. renal artery renal vein 1. Kidneys produce urine. aorta inferior vena cava 2. Ureters transport urine. 3. Urinary bladder stores urine. 4. Urethra passes urine to outside. Figure 11.1 The urinary system. 5
6 11.1 Urinary system What are the functions of the urinary system? 1. Excretion of metabolic wastes 2. Maintenance of water-salt balance 3. Maintenance of acid-base balance 4. Hormone secretion: renin and erythropoietin (EPO) 5. Reabsorb filtered nutrients and synthesize vitamin D 6
7 11.1 The Urinary System 1. Excretion Mostly of nitrogenous wastes Urea is made by the breakdown of amino acids in the liver. Uric acid is made by the breakdown of nucleotides. Creatinine is made by muscle cells from the breakdown of creatine phosphate. 7
8 11.1 The Urinary System 2 and 3. Maintenance of watersalt and acid-base balance These are homeostatic mechanisms. Water-salt balance helps to maintain blood pressure. The kidneys excrete hydrogen ions and reabsorb bicarbonate ions; this acid-base balance helps maintain a blood ph of
9 11.1 The Urinary System 4. Hormone secretion Renin secreted by the kidneys to allow the adrenal glands to secrete aldosterone to help regulate water-salt balance Erythropoietin secreted by the kidneys to stimulate red blood cell production when blood oxygen is low 9
10 11.1 The Urinary System 5. Reabsorb filtered nutrients and synthesize vitamin D The urinary system is responsible for reabsorbing filtered nutrients. Vitamin D is a molecule that promotes calcium absorption from the digestive tract. 10
11 11.1 The Urinary System How does the urinary bladder work? It stores urine, sphincters keep it closed. Expandable wall contains a middle layer of circular fibers of smooth muscle and 2 layers of longitudinal smooth muscle. Lining of transitional epithelium allows expansion of mucosa. Filling activates stretch receptors which signal to spinal cord. 11
12 11.1 The Urinary System Control of the urinary bladder brain spinal cord sections parasympathetic fibers (involuntary) urinary bladder ureter somatic nerve (voluntary) orifice of ureter internal sphincter external sphincter urethra Figure 11.2 Sensory impulses trigger a desire to urinate. 12
13 11.2 Kidney Structure What are the 3 regions of the kidney? Renal cortex an outer granulated layer Renal medulla cone-shaped tissue masses called renal pyramids Renal pelvis central cavity that is continuous with the ureter 13

15 11.2 Kidney Structure What are nephrons? Microscopic functional unit of the kidney that produces urine > 1 million per kidney 15
16 11.2 Kidney Structure What are nephrons? glomerulus and podocytes proximal convoluted tubule glomerular capsule efferent arteriole afferent arteriole renal artery Renal vein venule collecting duct Renal Cortex Renal Medulla loop of the nephron descending limb ascending limb peritubular capillary network Figure 11.4 The structure of a nephron. 16
17 11.2 Kidney Structure Anatomy of a nephron Glomerulus a knot of capillaries inside the glomerular capsule where pores produce a blood filtrate Proximal convoluted tubule epithelial layer with a brush border of microvilli to allow reabsorption of filtrate components Loop of nephron U-shaped structure that has a descending limb to allow water to leave and an ascending limb that pushes out salt 17
18 11.2 Kidney Structure Anatomy of a nephron Distal convoluted tubule made of epithelial cells rich in mitochondria and thus is important for movement of molecules from the blood to the tubule (tubular secretion) Collecting ducts several nephrons share a collecting duct which serve to carry urine to the renal pelvis 18
19 11.3 Urine Formation How does the nephron form urine? glomerular capsule H 2 O urea glucose salts amino acids uric acid Glomerular Filtration Water, salts, nutrient molecules, and waste molecules move from the glomerulus to the inside of the glomerular capsule. These small molecules are called the glomerular filtrate. proximal convoluted tubule Tubular Reabsorption Nutrient and salt molecules are actively reabsorbed from the convoluted tubules into the peritubular capillary network, and water flows passively. efferent arteriole glomerulus Tubular Secretion Certain ions and molecules (e.g., H + and penicillin) are actively secreted from the peritubular capillary network into the convoluted tubules. afferent arteriole end of another distal tubule renal artery distal convoluted tubule renal vein venule collecting duct Figure 11.6 An overview of urine production. loop of the nephron peritubular capillary network H 2 O urea uric acid salts NH 4 + creatinine 19
20 11.3 Urine Formation What are the three processes in the formation of urine? Glomerular filtration Tubular reabsorption Tubular secretion 20
21 11.3 Urine Formation Glomerular filtration Water and small molecules move from the glomerulus to the glomerular capsule, while large molecules and formed elements remain in the glomerular blood. Filterable Blood Components Water Nitrogenous wastes Nutrients Salts(ions) Nonfilterabe Blood Components Formed elements (blood cells and platelets) Plasma proteins 21
22 11.3 Urine Formation Tubular reabsorption and secretion Many molecules and ions are reabsorbed from the nephron into the blood. Tubular secretion is a second way to remove substances such as drugs, H + and creatinine from the blood. Reabsorbed Filtrate Components Most water Nutrients Required salts (ions) Nonreabsorbed Filtrate Components Some water Much nitrogenous waste Excess salts (ions) 22
23 11.4 Kidneys and Homeostasis The urinary system and homeostasis All systems of the body work with the urinary system to maintain homeostasis. these systems are especially noteworthy. Urinary System As an aid to all the systems, the kidneys excrete nitrogenous wastes and maintain the water salt balance and the acid base balance of the blood. The urinary system also specifically helps the other systems. Cardiovascular System Production of renin by the kidneys helps maintain blood pressure. Blood vessels transport nitrogenous wastes to the kidneys and carbon dioxide to the lungs. The buffering system of the blood helps the kidneys maintain the acid base balance. Nervous System The kidneys regulate the amount of ions (e.g. K +, Na +, Ca 2+ ) in the blood. These ions are necessary for nerve impulse conduction. The nervous system controls urination. Respiratory System The kidneys and the lungs work together to maintain the acid base balance of the blood. Digestive System The liver produces urea excreted by the kidneys. The yellow pigment found in urine, called urochrome (breakdown product of hemoglobin), is produced by the liver. The digestive system absorbs nutrients, ions, and water. These help the kidneys maintain the proper level of ions and water in the blood. Endocrine System The kidneys produce renin, leading to the production of aldosterone, a hormone that helps the kidneys maintain the water salt balance. The kidneys produce the hormone erythropoietin, and they change vitamin D to a hormone. The posterior pituitary secretes ADH, which regulates water retention by the kidneys. Muscular System The kidneys regulate the amount of ions in the blood. These ions are necessary to the contract ion of muscles, including those that propel fluids in the ureters and urethra. Integumentary System Sweat glands excrete perspiration, a solution of water, salt, and some urea. Figure 11.7 The urinary system and homeostasis. 23
24 11.4 Kidneys and Homeostasis How do the kidneys maintain homeostasis? Excrete wastes Urea, creatinine, and uric acid Water-salt balance of blood Helps regulate blood volume and pressure Acid-base balance of blood Helps regulate ph Assistance to other systems Endocrine, cardiovascular, skeletal, muscular, nervous, and digestive 24
25 11.4 Kidneys and Homeostasis What is the juxtaglomerular apparatus? Where the afferent arteriole and the distal convoluted tubule touch Secretes renin, which causes the release of aldosterone by the adrenal cortex 25
26 11.4 Kidneys and Homeostasis The juxtaglomerular apparatus proximal convoluted tubule proximal convoluted tubule distal convoluted tubule podocyte glomerulus collecting duct efferent arteriole glomerular capsule afferent arteriole juxtaglomerular apparatus distal convoluted tubule Figure 11.8 The juxtaglomerular apparatus of the nephron. 26
27 11.4 Kidneys and homeostasis How is blood volume and pressure maintained by the kidneys? Reabsorption of salt increases the blood volume Aldosterone promotes the excretion of K + and the reabsorption of Na +. Atrial natriuretic hormone (ANH) is secreted by the heart when blood volume increases and inhibits the secretion of aldosterone which promotes the excretion of Na +. 27
28 10.4 Kidneys and homeostasis How is blood volume and pressure maintained by the kidneys? Establishment of solute gradient a greater concentration is towards the inner medulla Reabsorption of water due to the solute gradient, water leaves the descending limb of the loop of the nephron; then antidiuretic hormone (ADH) from the pituitary plays a role in water reabsorption at the collecting duct 28
29 10.4 Kidneys and Homeostasis Increasing solute concentration in renal medulla Water reabsorption in nephrons Renal cortex Outer medulla H 2 O NaCl NaCl H 2 O H 2 O H 2 O NaCl H 2 O H 2 O descending limb ascending limb urea Figure 11.9 Movement of salt and water within a nephron. Inner medulla loop of the nephron collecting duct 29
30 10.4 Kidneys and Homeostasis What role does alcohol play in this process? Alcohol inhibits ADH secretion and thus increases the amount of urine and dehydration. 30
31 10.4 Kidneys and Homeostasis How is the acid-base balance maintained? Buffers are a chemical or a combination of chemicals that can take up excess H + or excess OH -. When H + are added to blood: H + + HCO 3 - H 2 CO 3 When OH- are added to blood: OH - + H 2 CO 3 HCO H 2 O 31
32 10.4 Kidneys and Homeostasis How is the acid-base balance maintained? The respiratory center in the brain can increase breathing rate if the buffers cannot maintain the ph. Ultimately, the kidneys are responsible for maintaining blood ph. 32
33 11.4 Kidneys and Homeostasis The kidneys and blood ph capillary HCO 3 H + Kidney tubule HCO 3 H + + NH 3 NH 4 + Figure Blood ph is maintained by the kidneys. 33
34 11.5 Kidney Function Disorders Kidney function disorders Diabetes, hypertension, and inherited conditions are the most common cause of renal disease and failure such as: Urethritis localized infection of the urethra Cystitis infection in the bladder Pyelonephritis infection of the kidneys 34
35 11.5 Kidney Function Disorders Kidney function disorders Kidney stones hard granules formed in the renal pelvis due to UTIs, enlarged prostate, ph imbalances, or intake of too much calcium Uremia high levels of urea and other waste substances in the blood that cause a serious condition when water and salts are retained due to extensive nephron damage 35
36 11.5 Kidney Function Disorders How can kidney failure be treated? Hemodialysis uses an artificial kidney machine to subtract and add substances to the blood as needed Continuous ambulatory peritoneal dialysis (CAPD) uses the peritoneal membrane to filter the blood and allows a person to go about their normal life without interruption Kidney replacement single kidney transplant with a high success rate 36
