Urinary System Part 2

Define the renal medulla.

Extends from the renal cortex to the renal sinus and possesses many conical shaped masses called renal pyramids

Define renal papilla

Nipple like structure; in b/t the renal medulla and renal pelvis; transfer urine from pyramids to the ducts

Define renal column

Inward extensions of cortical tissue that separate the pyramids

Define renal pelvis

Flat funnel shape tube that drains urine from the cortex and medulla towards the ureters

Define minor calyx

It's a branch of the renal pelvis that encloses the top of a single renal pyramid

What are the functional units of the kidney?

Nephrons

How many minor calyx does it take to make one major calyx?

4-5

The renal arteries enter the kidneys at the renal hilum to….

Bring oxygenated unfiltered blood into the kidney

Recite the blood flow of the kidney.

R. S. I. A. C. - A. G. E. P. - C. A. I

What is the overall purpose of the second capillary bed?

Transfer clean and deoxygenated blood to the veins and out of the kidneys via the veins

Each kidney has approximately ____ million nephrons.

1.25 million

Each nephron is made up of what?

A renal tubule and a renal corpuscle.

The renal tubule is made up of proximal convoluted tubule, distal convoluted tubule, and the loop of Henle.

The renal corpuscle is made up of a glomerulus. The glomerulus is made up of a knot of capillaries surrounded by Bowman's capsule.
