ureter

Tubes that move the urine from the kidney to the bladder

urinary bladder

Temporary storage reservoir for the urine before excretion

urinary bladder

C

liver

organ that forms the urea from nitrogenous waste in the blood

urethra

Tube which conducts the urine from the bladder to the outside of the body

urology

study of the urinary system

renal physiology or nephrology

study of kidney function

hilus

the portion of the kidney where the blood vessels, ureter, and nerves enter and exit the kidney

hilus

the region marked

renal cortex

the outer lighter region of the kidney

B

renal pelvis

center portion of the kidney where the urine is collected

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

efferent arteriole

blood vessel moving blood out of the glomerulus

efferent arteriole

A

peritubular capillaries

blood vessels which surround the nephron

peritubular capillaries

C

Renal Vein

D

Renal Artery

C

Afferent arteriole
