Reflex: Automatic response to a stimulus; happens very quickly and without conscious control. 3.1 Digestive System 1. Lipids are really Oils and Fats 2. Carbohydrates are really Sugars and Starches 4. Why does the stomach not digest itself? It has a mucus lining to protect it 5. Small finger-like projections that line the inner surface of the small intestine are called Villi. What do these projections do? Increase Surface Area of intestines to maximize nutrient absorption into bloodstream 6. Gastric Juice is produced in the Stomach. What four things is gastric juice composed of? Digestive enzymes, Hydrochloric acid, Water and Mucus Where is bile produced? The liver, stored in gall bladder, sent to small intestine when needed.
5 8. Describe Mechanical and Chemical digestion and give an example of where it takes place in your body. Mechanical Digestion is the physical ripping apart of food by the teeth, and the churning of food in the stomach. Chemical digestion is the breakdown of food using acids and enzymes in the stomach and small intestine 9. Describe in order, the pathway, in which food is digested. Be sure to list the organs involved in the process. 1. Mouth: Mechanical digestion (teeth) and Chemical Digestion (Saliva / enzymes) 2. Esophagus: Food is sent to the esophagus (the Trachea is protected by the epiglottis) where it is squeezed into the stomach (peristalsis) 3. The stomach digests food chemically and mechanically 4. Food moves into the small intestine where chemical digestion continues (villi) 5. The large intestine re absorbs water and creates vitamins and minerals 6. The rectum (anus) is the final stop for anything that was not absorbed during digestion 3.2 Respiratory System 1. What are alveoli and what do they do? Air filled sacs in the lungs that expand and contract with air. Capillaries are webs on the outside of the alveoli, gas exchange takes place (CO2 in, O2 out) between these two structures. 2. What effect does exercise have on breathing rate? Increases breathing rate as the muscle cells of the body need more oxygen. 3.3 Circulatory System 1. Sketch a heart labeling the 4 chambers and explain what those chambers do. Right Atrium: Collects deoxygenated blood from body, drops it into the right ventricle Right Ventricle: Pumps oxygenated blood into lungs Left Atrium: Collects oxygenated blood from lungs Left Ventricle: Pumps oxygenated blood to body
6 2. Describe in detail the roles that the left and right sides of the heart play. Right side collects deoxygenated blood from body and pumps it to the lungs Left side collects oxygenated blood from the lungs and pumps it to the body 3. Describe the different jobs that the atria and ventricles have. Atria are collectors, the load the ventricles. Ventricles are stronger, larger chambers that pump blood to lungs and body 4. The vessels that carry blood away from the heart to all the parts of your body are called Arteries. The vessels that return blood from your body to the heart are called Veins. The diffusion of nutrients and gases occurs in specialized blood vessels called Capillaries. 5. List the four different types of cells and materials found in blood and describe what they are responsible for. Red Blood Cells: Carry Oxygen White Blood Cells: Fight infection Platelets: Stop bleeding Plasma: liquid (mostly water) that allows blood to flow and carries dissolved nutirents 3.4 Excretory System 1. What is excretion? The removal of metabolic waste from the body 2. The Liver is an organ that takes highly toxic Ammonia out of the bloodstream and converts it into a less harmful waste substance called Urea. 3. What is the role of the kidneys in the excretory system? Filter urea from blood and add water and salt to create urine. They filter the blood in nephrons 4. Explain what the bladder is and how much urine the bladder can hold? Bladder is a sac that holds up to 1 Liter of urine until it can be pushed through the urethra at a convenient time. 5. Why do some people need to use a kidney dialysis machine and what does that machine do? Kidney disease or Diabetes, Dialysis is an artificial way to filter the blood, it takes over the role of the kidneys. 7. What substance is excreted in sweat? Salt 3.5 Nervous System
7 1. What are the two most important systems of the nervous system? And what are they made up of? a. Central Nervous System (CNS): Brain and Spinal Cord b. Peripheral Nervous System (PNS): The nerves in the back of the head and the rest of the body (Peripheral and Cranial nerves) 2. Explain what a sensory neuron does. Sends information from the body to the brain, via the spinal cord (Info from PNS to CNS) 3. Explain what a motor neuron does. Sends information from the brain to the body via the spinal cord (Info from CNS to PNS) 4. Explain the role of the somatic nervous system. Voluntary nervous responses (things you choose to do. Ex) Walking to school) 5. Explain the role of the autonomic nervous system. Automatic Nervous responses (things your body does unconsciously, without having to think. Ex) breathing, blinking, digesting 6. What is the control centre for your whole body? The Brain 7. The part that connects your brain to the other nerves throughout the body is called the Spinal Cord. 8. Responding to a noise you hear involves the Somatic and Autonomic Nervous system 9. Your pupils adjusting to a dark room involves the Autonomic Nervous system.
