Biomedical Test Review Urinary: Kidneys (filter blood, make pee) Ureteres (transports pee) Bladder (holds pee) Urethra ( releases pee) Main function: maintain fluid homeostasis in the body. Nervous: Brain (control center) Spinal cord (information highway) Peripheral nerves (carry signals to and from limbs) Eyes, ears, taste buds, etc. (collect sensory info and send it to the brain) Made up of neurons k. Immune: Thymus (promotes production of WBC) Tonsils (trap pathog/e/ns) Appendix (stores good bacteria) Spleen (filters blood) Lymph nodes (filter lymph fluid) Skin (prevents pathogens from entering body) Digestive: Teeth/Tongue (breaks down and pushes down) Pharynx (food/ air tube) Esophagus (food tube) Stomach (breaks down food) Small intestine (absorbs nutrients) Large intestine (absorbs water) Rectum (holds poo) Anus (releases poo) Respiratory: Nasal activity (opening to outside) Pharynx (air and food tube) Larynx (voice box, adam's apple) Trachea (air tube) Epiglottis (prevents food from entering air tube) Bronchi (branch into lungs)

Alveoli (site of gas exchange w blood) Cardio: Atrla (entrance for blood) Ventricles (pump out blood) Arteriole (carry blood away from heart) Vclns (bring blood to heart) Capillaries (siles of exchange with tissues) Endocrine: Hypothalamus (direct control of the endocrine system through the pituitary gland) Pituitary (help regulate the functions of other endocrine glands) Pineal gland (sleep/wake schedule) Adrenal (produce hormones that help the body control blood sugar, burn protein and fat, react to stressors like a major illness or injury, and regulate blood pressure) Thymus (develops immune) Testes/Ovaries (sex hormones) Thyroid (metabolic hormones) Pancreas (insulin) REVIEW Directional and Regional termsTissues: collections of similar cells that help perform a common function. A group of tissue is called an organ. Epithelial: Covers, lines organs and body cavities. Layers (one kind of cells inside & a different kind outside.) Muscle: Moves, makes up all muscles including the heart. Long and narrow so they can contact to allow movement. Nervous:Signals, includes neurons and neuroglia. Long axons to allow signals to travel distances, branches for connections. Connective:Joins, fairly consistent matrix to allow it to fill spaces of various shapes/sizes Functions of the human skeletal system: The skull and trunk protect soft organs such as the brain, heart, lungs, etc. The arms and legs provide attachment points for muscles that allow movement.
