KIDNEY DISECTION

QUESTIONS:

1What is the main function of the kidney?

The kidneys perform the essential function of removing waste products from the blood and regulating the water fluid levels

2Describe the pathway of blood through the kidney.

Blood flows through the kidneys at a very high rate. A person's entire blood volume passes through the kidneys 20 times per hour.
All of this blood is handled by a specialized system of arteries and veins. Arteries carry blood into the kidneys. 
Veins carry blood back to the heart.
From the abdominal aorta, blood enters the kidney through the renal artery.
The renal artery divides into a number of segmental arteries.

The segmental arteries divide into lobar arteries.

The lobar arteries divide into interlobar arteries that travel between the renal pyramids.

The interlobar arteries branch into arcuate arteries that travel between the cortex and medulla.

From the arcuate arteries, the blood is carried into microscopic arterioles that serve the nephrons.

3How did your distinguish between the renal atery and renal vein?

The renal artery comes off the aorta (the largest blood vessel in the body) carrying oxygen and nutrients to the kidneys. 

After going through the kidneys, the blood has less oxygen, and also contains waste products from the kidneys. These are the renal veins, and return to the heart for more oxygen. 

Arteries generally have thicker walls because it has to deal with a higher pressure (because it has to get to the whole body) 

Veins are generally thinner because they are a much lower pressure system.

4Which area of the kidney contains the glomeruli and Bowman´s capsules?

At the tubular component of a nephron.

5In which part of the kidney does the majority of water readsorption occur?

In nephrons

6What structure carries urine out of the kidney and where does it go?
