homeostasis

Question 1

homiosis - similar, stasis - standing still

Answer 1

homeostasis name

Question 2

internal and external balance for the body to maintain with homeostasis

Answer 2

dynamic equilibrium

Question 3

state of the body where internal physical chemical conditions are tolerable range for biological processes

Answer 3

homeostasis

Question 4

decrease in blood pH, <7.35

Answer 4

acidosis

Question 5

increase in blood pH, >7.45

Answer 5

alkalosis

Question 6

decrease in blood sugar

Answer 6

hypoglycemia

Question 7

increase in blood sugar

Answer 7

hyperglycemia

Question 8

extreme cold, dropping body temperature

Answer 8

hypothermia

Question 9

fever, increase in body temp

Answer 9

hyperthermia

Question 10

overactive thyroid

Answer 10

hyperthyroidism

Question 11

underactive thyroid

Answer 11

hypothyroidism

Question 12

receptor (monitor), control centre/CNS (integrator), effector (regulator)

Answer 12

homeostatic feedback loops

Question 13

sensors/receptors that receive stimulus from environment and send a message

Answer 13

receptor (monitor)

Question 14

control centre that relays the message from receptor to appropriate location in body for a response to occur

Answer 14

control centre/CNS (integrator)

Question 15

effector responds to message, leading in body change that restores homeostasis, e.g. glands, muscles, blood vessels

Answer 15

effector (regulator)

Question 16

receptor is thermostat sensor, stimulus is air temperature, control centre is thermostat, furnace is effector, desired temp is response

Answer 16

thermostat example

Question 17

maintain normal body constants, sensory receptor, stimulus, control centre, effector reverses change to equilibrium

Answer 17

negative feedback loops

Question 18

messages traveling from receptor to control centre along these

Answer 18

afferent nerves

Question 19

messages travel from the control centre to effector along these

Answer 19

efferent nerves

Question 20

don’t maintain homeostasis and used only when there is definite endpoint, intensify changes away from equilibrium

Answer 20

positive feedback loops impact

Question 21

to filter blood in order to remove waste fluid from body through urine

Answer 21

function of kidneys

Question 22

functional unit of kidneys, tubules, millions of them in each kidney

Answer 22

nephrons

Question 23

filtration, reabsorption, secretion, extretion

Answer 23

functions of the nephron

Question 24

begins in bowman’s capsule, urine formation begins by forming an ultrafiltrate that contains water, ions, glucose, amino acids, nitrogenous waste molecules, vitamins and minerals

Answer 24

filtration

Question 25

first part of the nephron

Answer 25

bowmans capsule

Question 26

blood vessels

Answer 26

glomerulus

Question 27

filtrate enters the proximal convoluted tubule where nutrients are reabsorbed by active transport, water leaves filtrate by osmosis through aquaporins, some secretion happens in proximal convoluted tubule when H+ is actively secreted to maintain blood pH

Answer 27

reabsorption 1

Question 28

filtrate moves into descending loop where additional water is reabsorbed, causing molecules + ions to become more concentrated, then ascending loop where high concentrations move out by passive transport and ions out of the tubule by active transport near the top, then enters distal convoluted loop where ions are reabsorbed, some secretion occurs in distal convoluted tubule where ions are secreted by active transport

Answer 28

reabsorption 2

Question 29

impermeable to water

Answer 29

ascending loop of henle

Question 30

filtrate enters collecting duct and H+ is secreted to maintain pH balance, secretion also occurs in proximal and distal convoluted tubes, reabsorption also occurs in the collecting duct

Answer 30

secretion
