What sphicters allow the flow of urine out?

A

Internal and external uninary sphincters

17
Q

What the differences between male and female urethra?

A

Male urethra:
longer than female
Divide into 3 regions: prostatic urethra, membranous urethra, and spongy urethra

Female:
Urinary bladder located inferior to the uterus

18
Q

What is a nephron?

A

It is a functional unit of the kidney

19
Q

What does the nephron contain?

A

Nephron is composed of a renal corpuscle and renal tubules that modifiy and secrete urine.

20
Q

Where does the filtration start?

A

Blood pass through the filtration membranes (glomerular capillary walls and visceral wall of the glomerular capsule) into the capsular (Bowman’s) space (glomerular cavity).

21
Q

Where does secretion starts?

A

Solutes leave the peritubular capillaries or vasa recta, diffuse through the ISF and cross the wall of the renal tubule and are elminated into urine.

22
Q

Where does resorption happen?

A

Cross the wall of the renal tubule, diffuse through the ISF and return to blood by entering the peritubular capillaries or vasa recta.

23
Q

The blood flow through the juxtamedullary nephron has what type of characterisitics?

A

They are longer they dip down farther into the medulla

Their blood supplies (capillary beds) have a speical name: vasa recta
