QUESTIONS AND CORRECT ANSWERS
Question:
1. anatomy
Answer:
the study of the structure of body parts
Question:
2. physiology
Answer:
the study of the function of body parts
Question:
3. levels of organization
Answer:
atoms, molecule, macromolecules, cell, tissue, organ, organ system, organism
Question:
4. What are the characteristics of life? (table 1.2)
Answer:
growth: increases the cell number and size and increases in body size
reproduction: production of new cells and organisms
responsiveness: reaction to a change inside or outside of the body
movement: change in body position or location, motion of internal organs
Question:
5. 3 requirements for life
Answer:
water: the most abundant substance in the body
heat: form of energy
pressure: application of force on an object
Question:
6. what is homeostasis
Answer:
maintenance of a stable internal environment
Question:
7. positive feedback
Answer:
a system where change is increased or amplified. ex. childbirth or blood clotting
Question:
8. negative feedback
, Answer:
a system that returns conditions back to normal ex. body temp regulation
Question:
9. difference between visceral and parietal membranes
Answer:
visceral: inner layer, covers the organ
parietal: outer layer, lines the cavity
Question:
10. functions of organ system
Answer:
integumentary (skin, hair, nails): protection, temp regulation
skeletal (bones, ligaments, cartilages): support, protection, blood cell production
muscular (muscles): movement and heat production
nervous (brain, spinal cord, nerves, sense organs): coordination and communication
endocrine: hormone secretion
cardiovascular (heart, arteries, capillaries, veins): transport of substances
lymphatic (lymphatic vessels, lymph nodes, thymus, spleen): immunity and fluid transport
digestive (mouth, tongue, teeth, etc): nutrient absorption
respiratory (nasal cavity, pharynx, larynx, trachea, bronchi, lungs): gas exchange
urinary (kidneys, ureters, urinary bladder, urethra): waste removal and water balance
reproductive: reproduction
Question:
11. what is anatomical position
Answer:
standing upright, facing forward, arms at side, and palms forward
Question:
12. relative anatomical terms
Answer:
superior: above
inferior: below
anterior: front
posterior: back medial: towards midline
lateral: away from midline
bilateral: paired structure on each side of midline
ipsilateral: structures on the same side
contralateral: structures on the opposite side
proximal: closer to trunk
distal: farther from trunk
superficial: near surface
deep: more internal parts
Question:
13. sagittall plane
