precapillary sphincters
tunica media
By a process called "capillary" action.
A nephron is composed of the Bowman's capsule, the proximal tubule, the loop of the nephron (called the loop of Henle), the distal tubule, and the collecting duct.
diapedesis
Sacs are called thylakoids.Stacks are called grana.
they squeeze through capillary walls in a process called diapedesis
Blood leaves a capillary through a venule, a small vein. At that point, the blood is making its journey back towards the heart.
From the heart the blood moves through the Artirioles, through the systemic capillaries, through the precapillary sphincters to the Venules, and back to the heart. Otherwise they are generally just called capillaries
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
The movement of the WBC through a capillary is called diapedesis. In very general terms it is also called extravasation
Diapedesis
The blood vessel that only allows one corpuscle to go through at a time is called a capillary.
