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.
