distal convoluted tubule
loop of hence

Question 7

What is the inner part of the kidney and what’s it made of

Answer 7

Question 8

This blood pressure forces plasma ,dissolved substances and proteins out of the glomeruli and into the Bowmans capsule

Answer 8

glomerular filtration

This is the amount of renal filtrate formed by the tubules in one minute and averages 100 to 125 ml per min

Answer 9

glomerular filtration rate

Question 10

Answer 10

c. active transport

Question 11

a. Growth hormone
b.Thyroxine
C. FSH
D.Parathyroid

Answer 11

D. parathyroid glands secrete PTH when the blood calcium level decreases.

Question 12

a. passive transport ,unlike charges attract
b. active transport , unlike charges attract
c, passive transport , alike charges attract

Answer 15

Intrinsic renal

Question 16

Answer 16

Postrenal failure

Question 17

This changes the composition of urine but substances are secreted from blood and filtrate in the renal tubules

Answer 17

Tubular secretion

Question 18

Waste products like ammonia and creating and the metabolic product is medication are secreted into the filtrate to ??

Answer 18

Be eliminated in urine

Question 19

Aldosterone helps maintain
a)normal blood volume and low blood pressure
B) irregular blood volume and high blood pressure
C) ph of the blood
D) normal blood volume and blood pressure

Answer 19

D) normal blood volume and blood pressure

Question 20

What happens in secretion of the renin

Answer 20

blood pressure decreases, the juxtaglomerular cells in the walls of the afferent arterioles secrete the enzyme renin.

Question 21

This initiates the renin-angiotensin mechanism to raise blood pressure.
The end product of this mechanism is angiotensin II, causes vasoconstriction and increase the secretion of aldosterone,both of which help raise blood pressure

Answer 21

Renin

Question 22

What happens with secretion of erythropoietin

Answer 22

Blood oxygen level decreases and RBM increases RBC production

Answer 23

Voluntary
