Systems
Term | Definition |
---|---|
Skeletal System | -supports and protects the organs -provides surfaces for attachment for muscle, tendon & ligaments -muscles attaches bone to tendon -ligaments attaches bone to bone |
Muscular System | -provides body with power for motion, movement & posture |
Gastroentestinal System | -breaks down food mechanically and chemically so that nutrients my be carried by the blood stream to body cells |
Respiratory System | -takes air into the body so oxygen can be carried from the lungs to the individual body cells -carbon dioxide waste is removed from body cells and taken to the lungs |
Cardiovascular System | -consists of blood, vessels & heart -arteries carry clean blood away from heart -veins carry blood back to heart to be cleaned Heart-arteries-arterioles-capillaries-venules-veins-heart |
Lymphatic System | -transports protein & fluids that have leaked out of the bloodstream into the fluid between cells back into blood stream |
Urinary System | -removes liquid waste products from the body which results in the combining of nutrients with oxygen in the blood cells -helps to retain the proper balance of water, salt & acids in the body |
Skin System | -serves as protective barrier against excessive loss of water, salts & heat -protects against invasion of pathogens & their toxins |
epidermis (skin system) | -has layers -no blood vessels |
dermis (skin system) | hair follicles, sweat glands, blood vessels -secretes oils to keep skin supple & free from cracking -helps maintain body temperature |
subcutaneus (skin system) | -acts as a receptor for sensation (pain, temperatures, pressure) |
Nervous System | -nerves & the brain coordinate voluntary actions & involuntary activities (breathing) -helps the body maintain homeostasis (everything normal) -enables memory and thought processess |
Peripheral Nervous System | -all nerves of the body, sensory (to brain), motor (away from brain) |
Endocrine System | -composed of glands located in different parts of the body which release a chemical substances called hormones into the body -hormones regulate functions such as bone growth, sex organs, |
Reproductive System | -sexual organs associated with reproduction of the species |
Sensory | -provides the brain with information about the surrounding environment |
anabolism | process of storing simple substances and combining them to make complex substances for body to use |
catabolism | process where complex substances are broken down to simpler substances & energy released |
cells - tissue - organs - systems | -enough cells make tissue; enough tissue makes organs; enough organs you have systems |
Digestive | mouth, throat, esophagus, stomach, intestines (small & large), liver, gallbladder, pancreas |
Urinary | kidneys, ureters, urinary bladder, urethra |
Resiratory | nose, throat, voice box, windpipe, bronchial tubes, lungs |
Reproductive | Female: ovaries, fallopian tubes, uterus, vagina, mammary glands Male: testes and associated tubes, urethra, penis, prostate gland |
Endocrine | thyroid gland, pituitary gland, sex glands, adrenal glands, pancreas, parathyroid glands |
Nervous | Brain, spinal cord, nerves |
Circulatory | heart, blood vessels(arteries, veins, capillaries) lumphatic vessels and nodes, spleen, thymus gland |
musculoskeletal | muscles, bones, joints |
skin & senses | skin, hair, nails, sweat glands, oil glands, eye, ear, nose, and tongue |
