This question we are going to discuss about ras okay which is basically what it is the renin angiotensin aldosterone system.
00:19
What is the function of this system? the function of the system is to regulate blood pressure, fluid volume and electrolyte balance.
00:46
Okay so how does this system work? first of all if there is a drop okay or say reduction so there is a drop in blood pressure or fluid volume.
01:02
What will happen when this happens? then renin will be released okay renin will be released from the kidney okay.
01:19
Now what does renin do? renin will act on angiotensinogen okay.
01:27
Renin acts on angiotensinogen okay.
01:38
What is angiotensinogen? it is a protein which is produced by liver okay.
01:49
So what does renin do? it will act on angiotensinogen okay and it will convert angiotensinogen to angiotensin 1 okay.
02:10
Who does this? this is done by renin.
02:14
Now what happens angiotensin 1 okay angiotensin 1 will be converted to angiotensin 2.
02:22
How is that conversion done? so there is an enzyme okay there is an enzyme called angiotensin converting enzyme okay and this enzyme is released from where? it is released from the lungs okay.
02:44
This enzyme is also known as ace.
02:48
So now what happens angiotensinogen is converted to angiotensin 1 okay by renin and then there is an enzyme called angiotensin converting enzyme which is released from the lungs okay...
