Question
What part of the nephron produces a filtrate of the blood that consists of water and solutes? A. Proximal convoluted tubule B. Distal convoluted tubule C. Collecting ducts D. Glomerulus
Solution
The part of the nephron that produces a filtrate of the blood that consists of water and solutes is D. Glomerulus.
Here's a step-by-step explanation:
-
Blood enters the kidney through the renal artery, which branches into smaller and smaller vessels until the blood reaches the nephrons.
-
Each nephron contains a structure called the glomerulus, which is a tiny knot of blood capillaries.
-
The glomerulus is where the filtration of blood takes place. Blood pressure forces water, salts, glucose, and other small molecules from the blood in the glomerulus into a tiny cup-like structure called Bowman's capsule.
-
The filtrate, which consists of water and solutes, then travels through the rest of the nephron (including the proximal convoluted tubule, distal convoluted tubule, and collecting ducts) where various substances are either reabsorbed back into the blood or further excreted into the urine.
So, the correct answer is D. Glomerulus.
