Regarding kidney has been given.

The first question that they have asked that what five substances form the filtrate? okay so the five substances that forms filtrate in the kidney that means that it will cross the membrane from the blood and the urine okay and would be filtered such as they are glucose, then you have water, then you have urea, then you have ammonia and various electrolytes like sodium, potassium, bicarbonate.
00:38
Next they have given what determines which blood components remain in the blood and which end up in the filtrate and the nephron.
00:45
So these are the substrate that is filtered out right from the blood.
00:49
Now what is going to determine whether these substances are going to filtered out or not? see first of all the size of the substrate okay as well as the size of the pores that is present in the glomerulus.
01:06
So these two is very important to filter out or to determine which is going to be the which is going to be those substances that are retained and which is going to be filtered because if they do not match okay then the substances will not be able to pass through the membrane of the glomerulus and they cannot be filtered out as well.
01:28
Next they have given which substances on the filtrate does your body need? so among this filtrate okay which of the substances do we see that our body needs? our body needs glucose, our body needs electrolyte.
01:43
Another substrate that i haven't mentioned here is amino acid...
