Select the correct statement about nephrons.
a. podocytes are the branching epithelial cells that line the tubules of the nephron.
b. filtration slits are the pores that give fenestrated capillaries their name.
c. the parietal layer of the glomerular capsule is simple squamous epithelium.
d. the glomerulus is correctly described as the proximal end of the proximal convoluted tubule.

The glomerulus is correctly described as the proximal end of the proximal convoluted tubule. (Ans D)

Explanation:

Proximal convoluted tubule (PST) is the portion (segment) of the nephron in the kidney. PST starts from the renal pole (of the bowmans capsule's) to the beginning of loop of henel. It can be classified into the :

Proximal convoluted tubule is used for selective re-absorption of nutrients (such as glucose, water etc.) from the tubules (cell lining of this tubules are ciliated for maximum surface area for re-absorption) fluid back into the blood.

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.
