Yes, it is true that capillaries play a crucial role in the nephron's function. Specifically, the glomerulus, a network of capillaries within the nephron, receives blood from the afferent arterioles and facilitates the filtration of blood to form urine. This process occurs before the filtered fluid passes through the renal tubules for further processing.
What else can I help you with?
True or False The kidney is composed of two blood filtering units called nephrons?
Tiny cells in the kidneys called nephrons filter the blood, they are composed of the glomerulus and the tubule. You have thousands of nephrons in each kidney.
Is it true that capillaries are the largest blood vessels?
No. There are three types of blood vessels. They are the arteries, veins, and capillaries. Arteries are the largest of the blood vessels. Then comes the veins and the smallest are the capillaries.
True or false Capillaries are where fresh blood is exchanged for old.?
I will tell you what a capillary is, but you should figure it out from there. A capillary is the tiny blood vessel that connects veins and arteries. The blood would go through the capillaries to reach one or the other. Remember: Arteries and veins each carry old or new blood. I can't remember what does what.
Is a venule is a tiny tube which gathers blood returning from the capillaries?
true
True or false blood vessels that carry blood to the heart are called arteries?
False. Blood vessels that carry blood away from the heart are called arteries. Blood vessels that carry blood to the heart are called veins.
Is A precapillary sphincter a cuff of smooth muscle that regulates the flow of blood into the capillaries?
true
Most veins carry deoxygenated blood true or false?
It is very true that most all veins carry deoxygenated blood.
The blood pressure gradient from the aorta to the capillaries is greater than the blood pressure gradient from the venules to the right atrium?
True
Is it true that substances are carried from the blood in capillaries to tissues in a liquid called tissue fluid?
yes
Is it true that intact capillaries near an injury dilate leaking plasma blood cells and antibodies cause the blood to clot?
False
Is it true that arteries carry blood that is rich with carbon dioxide away from the heart?
No, they carry blood rich with oxygen away from the heart to all the body.
True or false older red blood cells may be destroyed in the spleen?
True. There are blood capillaries within the red pulp of the spleen. Older, more fragile red blood cells may rupture as they pass through these capillaries and the resulting cellular debris is removed.
