00:01 Hello students, three will be solving a question in biology.

00:03 As you can see from the question they've given us that assuming there is no compensatory mechanism the blood pressure could be increased by all of the following options except one okay so the blood pressure could be increased by all of the following and we have to find the exception which cannot be increasing the blood pressure even when there is no compensatory mechanism and the options they've given us are increase arteriola diameter increase force of contraction increase viscosity in blood increase in heart rate and finally increase in sympathetic activities okay now the right answer for this question is option a increase in arteriola diameter this is because artriola diameter okay artriola diameter refers to the diameter of arteries it refers to the diameter of arteries it refers to the diameter of arteries which is around 100 micrometers.

01:06 So when this artrula diameter okay when this artuola diameter is increased then the space okay the space in the vessel also increases since the diameter of the arteries is increasing therefore the space in the vessels is also increasing which means that is a large space and here blood will be flowing faster when the vessels are narrow.

01:38 Blood flows faster in narrow vessels.

01:46 And when they are larger, then the movement of blood is low.

01:52 Moment of blood or any fluid is slow.

01:59 On keeping these points in mind, we can easily confirm that when the arteriolar diameter is increasing, it indirectly contemplates, it indirectly supports the resistance pressure.

02:13 Okay, it indirectly supports the resistance pressure and because of this resistance pressure the blood flow, okay, the blood flow is minimized and when blood flow is minimized it indicates that there is a low blood pressure.

02:41 So therefore we can see that out of all the following options they've given us, only option a, increased arteriolar diameter has the ability to decrease blood pressure rather than increasing.

02:54 Whereas the other options, increased force of contraction helps in increasing blood flow because it helps in narrowing of blood vessels...
