Textbook Question
Chapter 24, Problem 2MC
The glomerular capillaries differ from other capillary networks in the body because they (a) have a larger area of anastomosis, (b) are derived from and drain into arterioles, (c) are not made of endothelium, (d) are sites of filtrate formation.

(a) Describe the basic process and purpose of tubular resorption. (b) Explain the location and function of the peritubular capillaries.
The glomerulus differs from other capillaries in the body in that it
Question options:
a) is impermeable to most substances
c) has a blood pressure much higher than other capillaries
e) has a basement membrane
What is unique about blood flow out of the glomerular capillaries (Hint: what vessel drains them)? How does this help to explain why the pressure in the glomerular capillaries is higher than other capillaries?
