Question
- The nephron is the basic functional unit of the kidney. The constituent parts of the nephron include:a.Capillary endothelium, glomerular basement membrane, filtration slitsb.Glomerular capillary tuft, basement membrane, Bowman’s capsulec.Renal corpuscle, PCT, LOH and DCTd.JG cells, Macula densa
Solution
The nephron, which is the basic functional unit of the kidney, is composed of several parts. These include:
a. Capillary endothelium, glomerular basement membrane, filtration slits: These are all components of the glomerulus, which is the part of the nephron where blood is initially filtered to form urine.
b. Glomerular capillary tuft, basement membrane, Bowman’s capsule: These are also parts of the glomerulus. The Bowman's capsule is the cup-like sac at the beginning of the tubular component of a nephron that performs the first step in the filtration of blood to form urine.
c. Renal corpuscle, Proximal Convoluted Tubule (PCT), Loop of Henle (LOH) and Distal Convoluted Tubule (DCT): The renal corpuscle consists of the glomerulus and Bowman's capsule. The PCT, LOH, and DCT are all parts of the tubular system of the nephron, which further processes the filtrate into urine.
d. Juxtaglomerular (JG) cells, Macula densa: These are cells located in and near the glomerulus that help to regulate blood pressure and the filtration rate of the glomerulus.
So, all of the options listed are parts of the nephron, but option c. provides the most complete list of the major components of the nephron.
Similar Questions
The functional unit of the kidney is the nephron. Each kidney consists of millions of nephron which plays a significant role in the filtration and purification of blood. The nephron is divided into two portions, namely, the glomerulus and the renal tubule and helps in the removal of excess waste from the body.
