Which of the following is the structure through which blood exits the glomerulus?
Efferent arteriole
Proximal tubule
Distal tubule
Afferent arteriole.
The Correct Answer is A
The glomerulus is the main filtering unit of the kidney.
It is formed by a network of small blood vessels (capillaries) enclosed within a sac called the Bowman’s capsule.
The blood supply to the glomerulus is provided via the afferent arteriole.
The blood then flows through the capillary network, where it gets filtered, and then leaves the glomerulus via the efferent arteriole.
Choice B. Proximal tubule is not correct because it is where the ultrafiltrate collected in the Bowman’s space drains directly into.
Choice C. Distal tubule is not correct because it is not mentioned in relation to blood exiting the glomerulus.
Choice D. Afferent arteriole is not correct because it provides blood supply to the glomerulus.
