Which part of the nephron is involved in filtration? peritubular capillary glomerular capsule loop of Henle proximal convoluted tubule

Breakdown of the Question

The question asks which part of the nephron is specifically involved in the process of filtration.

Relevant Concepts

1. Nephron Structure: The nephron is the functional unit of the kidney, comprising various parts that perform different functions.
2. Filtration Process: Filtration primarily occurs in the renal corpuscle, which includes the glomerulus and the glomerular capsule (Bowman's capsule).

Detailed Analysis

1. Peritubular Capillary: These small blood vessels surround the renal tubules and are primarily involved in the reabsorption and secretion processes, not in filtration.
2. Glomerular Capsule: This is the cup-like structure that surrounds the glomerulus and is crucial for filtration. Blood enters the glomerulus, and water and solutes pass into the glomerular capsule, while larger molecules and blood cells remain in the bloodstream.
3. Loop of Henle: This part of the nephron is involved in reabsorption of water and salts; it does not play a direct role in filtration.
4. Proximal Convoluted Tubule: This segment is responsible for the reabsorption of nutrients, electrolytes, and water, rather than filtration.

Verification and Summary

Based on the roles of each nephron component, the glomerular capsule is the part involved in the filtration process, working in conjunction with the glomerulus.

Final Answer

The part of the nephron involved in filtration is the glomerular capsule.
