Functions of the Kidney
1. excrete nitrogenous waste
2. regulate blood volume
3. regulate electrolyte content
4. helps regulate acid-base balance in blood
5. produce renin which regulates blood pressure
6. produces erythropoietin which regulates rbc production
glomerulus
cluster of capillaries where filtration occurs from blood to nephron
glomerulus
A
Bowman's capsule
Cup-like structure of the nephron around the glomerulus which receives the filtrate from the blood
Bowman's capsule
B
proximal convoluted tubule
winding part of the nephron after the Bowman's capsule and before the loop of Henle
proximal convoluted tubule
C
loop of Henle
Section of the nephron which dips into the medulla of the kidney and returns, it is found between the proximal and distal convoluted tubule
loop of Henle
D and E
distal convoluted tubule
winding section of the nephron between loop of Henle and the collecting duct
distal convoluted tubule
F
collecting duct
the tube which multiple distal convoluted tubules drain into allow flow into the pelvis of the kidney
collecting duct
G
afferent arteriole
blood vessel moving into the glomerulus
Ureter
E
efferent arteriole
blood vessel moving blood out of the glomerulus
efferent arteriole
A
peritubular capillaries
blood vessels which surround the nephron
