HUMAN BODY SYSTEMS
STRUCTURES ORGANIZATION CELL - the smallest unit of living things TISSUE - cells, joined together for a similar functions. ORGAN - grouping of tissues that perform a specific function ORGAN SYSTEM - collection of organs that perform specific functions ORGANISM - comprised of multiple organ systems carrying out all life process
SOME OF THE ORGAN SYSTEMS Skeletal Muscle Respiratory Circulatory Endocrine Urinary Nervous Immune
SKELETAL SYSTEM The skeletal system is made of 206 bones, tendons, ligaments, and cartilage. The skeletal system has 6 main functions. Support Movement Protection Blood cell production Calcium Storage Endocrine Regulation

MUSCULAR SYSTEM There are 650 muscles in the body. These muscles perform many functions such as allow for walking, talking, standing, eating, and maintaining posture. There are three types of muscles. Skeletal, smooth, and cardiac.
MUSCULAR SYSTEM Skeletal Muscles- The only voluntary muscle tissue. Most attach to two bones across a joint to allow for movement. Smooth- Found in side organs liek the stomach and intestines. Cardiac- Involuntary muscles found only in the heart.

CIRCULATORY SYSTEM The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells. In the average human, about 2,000 gallons (7,572 liters) of blood travel daily through about 60,000 miles (96,560 kilometers) of blood vessels

ENDOCRINE SYSTEM The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, reproduction, sleep, and mood, among other things.
URINARY SYSTEM Also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys. The primary organs of the urinary system are the kidneys, which are bean-shaped organs that are located just below the rib cage in the middle of the back.
NERVOUS SYSTEM The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body s electrical wiring.
NERVOUS SYSTEM The nervous system has two components: the central nervous system and the peripheral nervous system The central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system.

IMMUNE SYSTEM The role of the immune system is to protect against disease or other potentially damaging foreign bodies. The major components of the immune system include: Lymph nodes Spleen Bone marrow
