Hi all, so in this question we are here asked to indicate the function and the fluid passage through different parts of this nephron.
00:11
So we know that nephron is the basic unit of kidney.
00:20
So this nephron has several parts so first we will see the parts and then the function and then the fluid passage.
00:28
So here the parts are first one is the proximal convoluted tubules.
00:37
So first one is the proximal convoluted tubule otherwise a pct then the loop of henle then the distal convoluted tubule and then the collecting duct.
00:49
So this is how a nephron look like that is here we can see this is the proximal convoluted tubule and then this loop of henle then the distal convoluted tubule and the collecting duct.
01:03
So these are the basic parts of this nephron and along with this there is bauman's capsule glomerulus which are situated in the medulla region of this nephron.
01:15
Now we will see the functions of each.
01:19
So first one is the pct otherwise a proximal convoluted tubule.
01:24
So this pct is responsible for the reabsorption of the majority of filtered substances such as glucose, amino acids, ions etc.
01:34
And it has also play a major role in the secretion of waste products, drugs and toxins into the tubular fluid.
01:43
Now coming to the fluid passage, their fluid passage will be that after the filtration in the glomerulus this will enter the pct and from there the reabsorption and a secretion takes place.
01:59
Now next is a loop of henle.
02:02
So this loop of henle will create an osmotic gradient in the kidney medulla and this is very important in the process of water reabsorption as well as in concentration and this mechanism is usually called as a counter current mechanism, counter current ion mechanism...
