the heart

Question 1

right side heart

Answer 1

deoxuganated blood enters the right side artrium from the body pushed by muscle in the right ventricle to the lungs where is oxyganted

Question 2

left side heart

Answer 2

oxyganted blood returns from lungs to the left artrium it is then pushed to the left ventricle and then out the body thru eaorta.

Question 3

cardiac output

Answer 3

heart rate x stroke volume

Question 4

arteries

Answer 4

thick wall
smooth muscle
narrow luman

withstand high blood pressure
allows walls to strech whrn blood is pumped into the arteries

Question 5

capillaries

Answer 5

very thin walls
small luman

allow gas exchange between blood and tissues
links arteries and veins

Question 6

veins

Answer 6

thin walls
little smooth muscle
wide luman
valves

valves stop backflow

Question 7

cardiac distole

Answer 7

no contraction

heart refills with blood

Question 8

atria distole

Answer 8

contraction

blood in artrium forces into ventricle

Question 9

ventricular distole

Answer 9

ventricles contract causing lood to leave the heart forces open semilunr valve

Question 10

p wave

Answer 10

time of atria systole

Question 11

t wave

Answer 11

repolarisation of ventricles during distole

Question 12

path of blood cells through the heart and lungs

Answer 12

passes into right artrium through the triscupid valve into the right ventricle into the lungs via pulmanory arteries
From lungs to left artrium via pulamory vein thru the triscupid valve into the lft ventricle to rest of body thru aeorta

Question 13

anti-hypertensive

Answer 13

reduce high blood pressure

Question 14

statins

Answer 14

reduces ldl by inhabiting enzymes in the liver

Question 15

tranplantation

Answer 15

properly functioning heart

Question 16

high blood pressure

Answer 16

damage lining of arteries and increse risk of blood clot

Question 17

structure of alveoli to adapt to its function

Answer 17

large surface area so maximisung rate of diffusion

Question 18

breathing in

Answer 18

diagpram contracts and moves down to become flat
intercost contract and move ribcage upwards and downwards
volume of chest increases
pressure decreses in lungs compared to outside
air rushes in

Question 19

breathing out

Answer 19

internal intercosts contract and move cahe upwards and downwards
adominal muscles contract and push digrpam back up
volume of chest decreses
air rushes in

Question 20

renal vein

Answer 20

takes reabsorbed nutrients back into the blood away from kidney

Question 21

kidney

Answer 21

filters blood to remove waste which converts into urine

Question 22

adh

Answer 22

hormone relesed by pitutary glands that effect permability

Question 23

with adh

Answer 23

makes the walls of the collecting duct permamble to water and leaves by osmosi

Question 24

without adh

Answer 24

hypotenic filtrate passes thru collecting dust unchanged producing high levels of urine

Question 25

neuphron

Answer 25

responsible for the production of urine in order to get rid of toxins

Question 26

diffusion

Answer 26

region of high con to low con

propartional to concentration gradient

Question 27

osmsis

Answer 27

high water pot to low water pon

Question 28

phagocytis

Answer 28

move into cells

structure surrounded by cell membrane and engufled by vesicles when moves into cell
