Hello everyone, in this video we have a mcq and we are going to solve this mcq.
00:06
So the question is which blood level of which gas is important for cellular respiration.
00:12
So five options are given n2 carbon monoxide and carbon dioxide, nitrogen, okay? so first before getting into the question, we have to know something about the respiration center.
00:27
So the respiration center is present in the upper brain stem, that is in the medulla obligata and ponds.
00:35
So there are three groups of respiratory neurons present, the ventral, the dorsal, and the pontein.
00:43
So the ventral and dorsal is present in the medulla and the pontine respiratory center is present in the ponds.
00:50
And this respiratory center controls the respiration rate of a body or involuntary rest.
00:57
So we know the respiration is not under control.
01:01
It is some, it's an involuntary process, right? we are breathing in and breathing out and it's an involuntary process.
01:07
We, during even during sleep, we breathe in and breathe out.
01:11
This is what is controlled by the respiration center.
01:14
So it's an involuntary process, which is controlled by respiration center.
01:19
So as i said before, the respiration center is responsible for generating and maintaining the rhythm of respiration, right? so, this respiratory center receives input from chemoreceptors, mechanoreceptors and the cerebral cortex and hypothalamus in order to regulate the rate and depth of breathing.
01:40
So whether you have to take a deep breath or a very light breath.
01:44
So these all are controlled by the respiratory center and it receives input from chemoreceptors, mechanoreceptors, cerebral cortex and hypothalamus...
