Homeostasis

Question 1

Physiology

Answer 1

the structure function relationship of a healthy animal

Question 2

Anatomy

Answer 2

structures of an animals body, dictate how the parts will function

Question 3

intracellular fluid

Answer 3

fluid inside cells

Question 4

extracellular fluid

Answer 4

blood, plasma, and other fluids outside the cell

Question 5

cells

Answer 5

obtain nutrients and oxygen, undergo metabolism for energy production. connected by junctions (adhesive, tight, gap) to form tissues

Question 6

tissues

Answer 6

multiple cells, distinguished by type, cell arrangement and cell junctions

Question 7

epithelial tissue

Answer 7

skin, lining of digestive tract and glands

Question 8

connective tissue

Answer 8

tendons and fascia

Question 9

muscle tissue

Answer 9

skeletal, cardiac, smooth. generate electrical signals and have contractile properties

Question 10

nervous tissue

Answer 10

neurons. excitable cells, transmit signals

Question 11

organs

Answer 11

different types of tissues (heart, liver, brain, small intestine, etc)

Question 12

systems

Answer 12

collection of organs

Question 13

nervous system

Answer 13

electrical signals

Question 14

endocrine system

Answer 14

chemical signals (hormones)

Question 15

muscular/skeletal system

Answer 15

support and movement

Question 16

cardiovascular system

Answer 16

nutrient/waste transport

Question 17

renal system

Answer 17

fluid volume, pH, electrolyte balance, waste removal

Question 18

respiratory system

Answer 18

gets oxygen, removes CO2, pH balance

Question 19

digestive system

Answer 19

gets nutrients, gets rid of waste

Question 20

reproductive system

Answer 20

not essential, keeps species alive

Question 21

integrate

Answer 21

work together

Question 22

osmolarity

Answer 22

measurement of solute concentration in a solution (bodily fluids). fluids with high concentration solutes relative to solution have high osmolarity

Question 23

serum osmolarity

Answer 23

isotonic - 300 mmol/L
Hypertonic - > 310-320 mmol/L
Hypotonic - < 280 mmol/L

Question 24

osmosis

Answer 24

ions in solution

Question 25

homeostasis

Answer 25

maintains stable state (constant internal environment) for optimal health (oxygen, pH, glucose, body temp, electrolytes, waste)

Question 26

feedback loops

Answer 26

continually monitor conditions in the body and turn on or off responses, communication between components in an organism

Question 27

negative feedback loop

Answer 27

response opposes and removes a signal and restores the regulated variable (thermoregulation, endocrinology, blood pressure, pH, blood glucose levels)

Question 28

positive feedback loop

Answer 28

response reinforces change (not just on/off) (uterine contraction during birth = oxytocin feedback loop) (normal blood clotting homeostasis)

Question 29

blood clotting homeostasis

Answer 29

stimulus causes blood clots which stops the bleeding

Question 30

parturition homeostasis

Answer 30

fetus at full term pushes on the cervix, causes birth
