Question

Which statement below regarding the filtration bed absorption/secretion beds is TRUE?

1) Both types of beds have both fenestrations and filtration slits
2) Filtration beds are found surrounding the PCT and DCT
3) Absorption and secretion beds are found in the renal corpuscle
4) Filtration beds make up the peritubular capillaries
5) Reabsorption and secretion beds make up the glomerular capillaries

Answer 1

2), The true statement regarding filtration bed absorption/secretion beds is that filtration beds make up the peritubular capillaries, which are involved in reabsorption and secretion and surround the PCT and DCT. Filtration occurs in the glomerulus of the renal corpuscle.

Step-by-step explanation:

Among the statements provided regarding the filtration bed absorption/secretion beds, the true statement is that: Filtration beds make up the peritubular capillaries. The peritubular capillaries surround the proximal and distal convoluted tubules (PCT and DCT) of the nephron and are involved in reabsorption and secretion functions. Filtration, on the other hand, occurs at the glomerulus which is found in the renal corpuscle. The glomerular capillaries are specialized for filtration, characterized by fenestrations and filtration slits formed by podocytes that allow the passage of most solutes, except for large proteins and cells, into Bowman's capsule to form the initial filtrate that will become urine after further processing in the nephron.
