Which anatomical structure encloses the renal glomerulus?
Solution
Correct Answer: Option A
- The renal glomerulus is a network of capillaries that plays a crucial role in the filtration of blood to form urine.
- The structure that encloses the renal glomerulus is the Bowman's capsule.
- This capsule is a cup-shaped sac that collects the filtrate produced by the glomerulus and directs it into the nephron for further processing.
- The Bowman's capsule has two layers: the visceral layer, which closely surrounds the glomerular capillaries, and the parietal layer, which forms the outer wall of the capsule.
- The space between these layers is called the Bowman's space or urinary space, where the filtrate is first collected.
Other options such as the proximal convoluted tubule, Loop of Henle, and distal convoluted tubule are parts of the nephron that come after the Bowman's capsule in the urine formation pathway. They are involved in the selective reabsorption and secretion processes but do not enclose the glomerulus.
In summary:
- The Bowman's capsule encloses the renal glomerulus.
- It collects the filtrate generated during the blood filtration process.
- Other nephron components process the filtrate downstream.
