What are the two types of nephron?
There are two types of nephron, those with long Henle’s loops and those with short loops. Short loops turn back in the outer medulla or even in the cortex (cortical loops).
What is the basic unit of the kidney?
The functional unit of the kidney is the nephron, which consists of a tuft of capillaries, termed the glomerulus, found within the Bowman’s capsule located in the cortex.
What are the 4 functions of the nephron?
The primary function of nephron is removing all waste products including the solid wastes, and other excess water from the blood, converting blood into the urine, reabsorption, secretion, and excretion of numerous substances.
How many nephrons are there?
nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood. There are about 1,000,000 nephrons in each human kidney.
What is the fluid in the PCT called?
This filtrate, called tubular fluid, collects in a cup shaped structure containing the glomerulus called the Bowman’s capsule. Together, the glomerulus and the Bowman’s capsule make up the renal corpuscle.
What happens when PCT is removed?
The water potential as a result of absorption of solutes decreases in the capillaries and hence the water from the filtrate too moves into the capillaries across the PCT. As a result, if the PCT is removed, it will lead to the formation of highly dilute urine. Hence, the correct option is more diluted urine.
What is the function of PCT in kidney?
Difference between PCT and DCT:
| PROXIMAL CONVOLUTED TUBULE | DISTAL CONVOLUTED TUBULE |
|---|---|
| FUNCTION | |
| A small amount of tubular secretion also takes place in the Proximal Convoluted Tubule (PCT). | The secretion of wastes of ions takes place in the Distal Convoluted Tubule (DCT). |

How many nephrons are born?
months of age, we found that nephron number ranged from approximately 250,000 to 1.1 million. Given that no new nephrons are formed in human kidneys after approximately 36 weeks’ gestation, much interest has focused on renal function and health in individuals born with relatively low nephron endowment.
What will happen if PCT is removed?
What happens if the proximal convoluted tubule is damaged?
Packed with mitochondria and dependent on oxidative phosphorylation, the proximal tubule is particularly vulnerable to injury (obstructive, ischemic, hypoxic, oxidative, metabolic), resulting in cell death and ultimately in the formation of atubular glomeruli.
