21
Q

how is water and blood regulated in your body

A

though your kidneys

22
Q

what are the components of the urinary system

A

kidney
ureter
bladder
uretha

23
Q

kidneys filter and clean

A

your blood and water

24
Q

what in your kidneys does the filtering of blood and water

A

neurons

25
Q

waste exits your

A

uterer

26
Q

what does dialysis do

A

kidney’s jobs

27
Q

what is osmoregulation

A

when kidneys send a signal to your brain (hypothalamus) by releasing diuretic hormone to pee more

28
Q

when you have too little water your kidney send a signal to

A

hypothalamus by releasing anti diuretic hormones to retain more water

29
Q

diuretic =

A

signal to pee

30
Q

anti diuretic =

A

signal to retain water

31
Q

what are the 2 things measured during blood pressure check

A

systolic
diastolic

32
Q

what is considered normal blood pressure

A

120/80

33
Q

what is considered high blood pressure

A

130 up/ 89 up

34
Q

what are ways to maintain a good blood pressure

A

clean diet
excersize
less stress

35
Q

why do people faint

A

not enough blood to the brain
low blood pressure

36
Q

what is a vagus nerve control

A

heart rate

37
Q

how is low blood sugar regulated

A

enters pancreas
glycogen released by liver
liver releases glucose into blood to achieve normal blood glucose levels

38
Q

how is high blood glucose regualted

A

enters pancreas
insulin released by beta cells of pancreas
achieve normal blood glucose levels

39
Q

what causes type 1 diabetes

A

your beta cells in your pancreas doesn’t make insulin

40
Q

type 1 diabetes is also known as

A

juvenile diabetes

41
Q

type 2 diabetes is considerd

A

environmently made

42
Q

what happens in type 2 diabetes

A

your cells are desensitized to take up the glucose

43
Q

in type 2 diabetes do you make insulin

A

yes, lots of it
the problem is in the valve

44
Q

what is the endocrine system

A

organ system involved with homeostasis

45
Q

pineal glands are related to

A

sleep patterns

46
Q

pancreas =

A

blood glucose

47
Q

thyroid gland is associated with

A

metabolism

48
Q

pituitary gland is associated with

A

growth, gametes, osmoregulation
