Hello students, let us consider the statements given here and these statements are related to the blood osmolarity, volume and pressure.
00:11
We have to consider whether they are true or false.
00:14
The keynote here is whether the statements that are given in the question is true or false and then say whether the following given statements are true or false.
00:25
So if we consider osmolarity, osmolarity indicates the concentration of solute in a solution.
00:40
This is osmolarity.
00:44
In case of blood, sodium, potassium, these ions, they act as solute.
00:54
These ions they will act as solute, whereas the blood itself acts as solution.
01:04
Now based on this if we consider, if the concentration of solute increases, concentration of solute increases in the blood, then inflow of water increases.
01:26
Due to this inflow of water, the concentration of the solute will be diluted and decreases.
01:41
As a result, there will be rise in the blood volume due to inflow of water.
01:54
The rise in the blood volume also leads to increase in the blood pressure.
02:02
Blood pressure is also increased.
02:06
Various hormones, secretions, they are used to control or regulate blood pressure.
02:24
And this diluted leads to lower the concentration of solute.
02:31
Sillute concentration will be decreased.
02:35
That is, sodium and potassium, concentration will decrease.
02:39
Now based on this explanation let us move to the statements that is given to us starting from the statement one.
02:48
Blood osmality falls when sodium levels in the blood decline.
02:54
This is true because osmolarity of the blood is due to high concentration of sodium and potassium ions.
03:15
So whenever sodium ions decrease, obviously the concentration of solute decreases.
03:29
Concentration of solute in the blood decreases.
03:33
Due to this, osmolarity of the blood also decreases.
03:41
Now let's move to the second statement.
03:49
As sodium levels rise, so does the blood volume and blood pressure.
03:56
Whenever the sodium levels increase, this leads to rise in the concentration of solute, concentration of solute.
04:17
In order to this, or balance the concentration of solute or balance the osmolality, water inflow increases.
04:39
There will be increase in the water inflow into the blood.
04:45
This inflow leaves to rise in blood volume, blood pressure.
04:58
Blood volume and blood pressure increases.
05:09
Let's move to the, so the answer here is if this is true.
05:14
This statement is true statements.
05:19
Next move to the third statement.
05:20
Statement three is false statement because here concentration of solute increases, then the blood volume and blood pressure increases.
05:48
Antidiotic hormone and angiotensin 2 are used to regulate blood volume and blood pressure...
