What is different about the wall of the left ventricle?

2 and convoluted.
What is the role of ADH?

What does the pulmonary vein do?
Carries oxygenated blood to the left atrium from the lungs.
What is used to help remember route that blood takes?
VA VA VA
What happens in VA 1?
Deoxygenated blood enters the heart at the vena cava, passes through the right atrium
What happens in VA 2?
then the right ventricle leaving the heart. The blood then enters the pulmonary vein as oxygenated blood, and enters the left atrium
What happens in VA 3?
goes through the left ventricle passing out of the heart via the aorta
What is the artery(in) and vein(out) from and to the kidney?
Renal artery and renal vein.
What is a glomerus?
Network of capillaries.

First convoluted tubule.
What is the third part of the kidney?
Loop of henle.
What is the fourth part of the kidney?
Second convoluted tubule.
What is the fourth part of the kidney?
Collecting duct and then it goes out to ureter.

Deoxygenated blood from heart to lungs.
