From the question they given us to identify the substances that are involved in reabsorption of which undergoes reabsorption in the nephrons especially in the proximal convolvulated tubule.
00:31
Proximal convolvulated tubules will reabsorb certain substances we have to identify those substances and we also have to identify the substances which are not going to be reabsorbed in the given compounds.
00:49
They provide that from this we have to identify the substances that are going to be reabsorbed and not reabsorbed.
00:56
In the condition of reabsorb, in general, a proximal convoluted tubule will be passed with the glomerular filtrate i .e.
01:19
Gfr about 120 ml per minute have been passed off.
01:25
Under this condition, a proximal convoluted tubule major reabsorption will consist of about lesser amount of water and increased amount of solutes and the lesser amount of ions being reabsorbed.
01:52
In this condition, they provide that certain substances or reabsorbing substances are amino acid.
02:00
In general, the amino acid must be enters into the blood to undergo regeneration to synthesis the protein.
02:10
Therefore, amino acid will be reabsorbed.
02:13
But in the condition, a bicarbonates are also involved in reabsorption because they are very important during the buffering system to be performed by our body.
02:28
Another important substance is going to be our glucose.
02:33
In general a 0 % glucose is released in urine that means all of the glucose are being reabsorbed by our body.
02:44
Most of them are reabsorbed in proximal the convorated tubal excite.
02:50
But it also involved in reabsorption of h plus ions because if the bicarbonate ion is going to produce a basic ph when the h plus ions are reabsorbed it produces acidic ph.
03:04
Therefore they are very important for the buffer system of our body.
03:10
Then a lactate are also being reabsorbed because a lactate is going to be a storage form of energy during glycolysis.
03:22
Another important is going to be a peptide hormones.
03:25
In general, peptide hormones are not generated in glomerular filtration plate itself but it enters the encounter after the glomerular filtration and enters into the proximal convertiated tubule.
03:37
Any amino acids or proteins or peptides are being reabsorbed by the proximal convertiated tubule.
03:43
They would most be absorbed.
03:45
Then then in the case of ions, sodium ions are being reabsorbed and urea is going to be reabsorbed at the lesser amount.
04:06
Both of them are released into the urine where lesser amount of urea will be absorbed and enters into the blood which produces the serum, a blood urea level to be present.
04:21
And the water is also reabsorbed at the lesser amount not more amount of water is going to be reabsorbed.
04:32
Therefore, these are the substances to be reabsorbed...
