16
Q

structure of nephron

A

they are very small, they have their own bloody supply, branching off the renal artery.

17
Q

what is the bowman capsule

A

it collects filtrate forced out of the glomerulus and allows to enter kidney tubes.

18
Q

what is a glomerulus

A

it filters bloody by increasing pressure to produce filtrate to enter Bowman’s capsule

19
Q

Convoluted tubules

A

filtrate flows through these and useful substance in the filtrate are reabsorbed back into the blood capillaries wound around them.

20
Q

loop of Henle

A

it maintains water concentrations in the body by filtering out salts

21
Q

collecting duct

A

it reabsorbs water back into the blood depending on levels of ADH in blood and collects urine to pass on to the ureter

22
Q

what is ultrafiltration

A

all blood is filtered and wall water, urea and salts more into the nephron tubule,

23
Q

in ultrafiltration what is taken out of blood

A

water, salts, glucose, urea

24
Q

first process of ultrafiltration

A

arterioles branch of the renal artery and lead to each nephron, where they go to the glomerulus sitting inside bowman’s capsule

25
Q

second process of ultrafiltration

A

the capillaries get narrower as they get further into the glomerulus which increases the pressure on the blood moving through them.

26
Q

third process of ultrafiltration

A

this causes small molecule being carried on the blood forced out of the capillaries and into the bowman’s capsule.

27
Q

substances taken out if blood during ultrafiltration

A

glucose, water, urea and salts

28
Q

where is water reabsorbed at

A

collecting duct

29
Q

where is salt reabsorbed at

A

loop of Henle

30
Q

where is glucose reabsorbed at

A

proximal convoluted tubule

31
Q

where is urea reabsorbed at

A

not reabsorbed

32
Q

what comes after the bowman’s capsule

A

PCT

33
Q

what comes after the PCT

A

loop of Henle

34
Q

what comes after loop of Henle

A

DCT

35
Q

what come after the DCT

A

collecting duct

36
Q

how is glucose reabsorbed

A

active transport

37
Q

how is the nephron adapted for active transport

A

high number of mitochondria

38
Q

what is diabetes

A

people who can’t control their blood Suger levels

39
Q

if you have diabetes where does urine sometimes go

A

in their urine

40
Q

how is water reabsorbed

A

osmosis

41
Q

what does ADH do

A

it lowers the amount of water reabsorbed into the blood

42
Q

where is ADH created

A

its is created in the pituitary gland
