Chapter 1 Intro to the human body Flashcards
Definition of anatomy?
The science of body structures and the relationships among them
Definition of physiology?
The science of the body’s functions
Organization of body
- chemical
- cellular
- tissue
- organ
- system
- organism
example/function of integumentary system
skin: protection, heat regulation, eliminate waste, store fat
example/ function of skeletal system
bones/joints: supports/protects/houses cell that make RBC
example/function of muscular system
muscle: attached to bone, produce heat/ maintain posture, move body
ex/funct of nervous system
brain, spinal cord, nerves, eyes/ears: detects changes inside and outside body, interprets, react by cause muscle contraction, glandular secretion aid
ex/funct of endocrine system
hormone producing cells/organs: regulates body by releasing hormones
ex/funct of cardiovascular system
blood, heart, blood vessels, capillaries: move waste and nutrients throughout body via blood/blood vessels.
ex/funct of lymphatic system
lymphatic vessels, spleen, thymus, lymph nodes, tonsils (b-cells, T-cells): return protien/fluid to blood, carry lipids from GI tract to blood, contain site for maturation and proliferation of B/T cells (WBC)
ex/funct of resp system
Lungs, upper airways, nares, mouth, trachea, carina: regulate acid/base balance via respiration, get rid of waste via respiration and take in oxygen via diffusion into the blood.
ex/funct digestive system
stomach, epiglottis, GI tract, anus, mouth: breakdown food (accessory organs- gallbladder, liver, salivary glands, pancreas)
ex/funct of urinary system
bladder, ureters, kidneys: helps regulate production of red blood cells, gets rid of waste
ex/funct of reproductive system
Testes, penis, ovaries, uterus, Fallopian tubes, vagina, breasts, cervix: procreate, develop sex hormones
Basic Life Process
- metabolism: catabolism, anabolism
- responsiveness: detect/respond to change
- movement
- growth: hypertrophy, cell multiply
- differentiation: form specialized, un-specialized cells
- reproduction: form new cells for tissue growth, repair, replace. production of new individual.
