Which structure houses the glomerulus in the kidney?

The glomerulus is a network of tiny blood vessels (capillaries) located within the renal corpuscle, which is the initial part of the nephron in the kidney. It is specifically housed in a structure known as Bowman's capsule. This capsule encases the glomerulus and plays a crucial role in the filtration of blood. When blood enters the glomerulus, various substances, including water, ions, and small molecules, are filtered into Bowman's capsule, forming the initial filtrate that will eventually be processed into urine.

The other structures mentioned do not directly house the glomerulus. The Loop of Henle is responsible for the concentration of urine and is located further along the nephron. The proximal convoluted tubule is involved in the reabsorption of vital substances from the filtrate but is downstream from Bowman's capsule. The distal convoluted tubule also plays a role in further processing the filtrate but does not contain the glomerulus. Thus, Bowman's capsule is the correct answer as it directly encases the glomerulus and is integral to the kidney's filtration process.
