Today we are going to do a very interesting job regarding lungs pathologies.
00:06
First of all, we have an m -cq to solve.
00:12
Which of the following non -respiratory movements is caused by irritation of the diaphragm.
00:19
Okay, laughing.
00:21
Laughing is not caused by the irritation of diaphragm.
00:24
Laughing involves movements of muscles of face and cheeks.
00:29
Same is the case with crying.
00:32
It involves muscles of face, cheeks, and throats.
00:36
While the mechanism of cuff.
00:40
Mechanism of cuff is the diaphragm that is innervated by phanic nerve and external intercostal muscles innervated by segmental intercourseal nerves contract, creating a negative pressure around the lungs.
00:54
Here rushes into the lung in order to equalize the pressure.
00:57
Yes.
00:58
Cuffing involves the diaphragm.
01:03
Now, the next is hiccups.
01:07
Hicups are actually involuntary contractions of diaphragm.
01:13
The muscle is the diaphragm is the muscle that separates our chest from the abdomen and plays an important role in breathing.
01:21
The involuntary contraction in the hiccups cause our vocal cords to close very briefly, which produces a characteristic sound of hiccups.
01:30
So, hiccups involve involuntary movements of diaphragm that are non -respective.
01:34
Now, in the last we have sneezing.
01:40
The sneeze center sends the signals the part of our body that need to work together to help us sneeze.
01:48
Our chest muscles, diaphragm and abdominal muscles, including vocal cords of throat, and muscles in the back of our throat all work together to help us expel the irritants.
02:02
Yes, it involves diaphragm also and it is non -restorism.
02:06
Respiratory movements.
02:10
Now, next question is, hemoglobin has the tendency to release oxygen where option one is partial pressures of oxygen are higher, no.
02:22
When the partial pressure of oxygen in the environment is low, hemoglobin tends to release the oxygen to equalized or equilibrate the partial pressure of oxygen.
02:34
Where the ph is more acidic, yes, we know that carbon dioxide present reacts with water to form carbonic and hydrate, sorry, bicarbonate bicarbonic acid.
02:52
This bicarbonic acid now dissociates into protons plus bicarbonate ion.
03:03
This creates acidic environment.
03:05
An acidic environment is here or it is increased amount of carbon dioxide in the environment.
03:10
The hemoglobin tends to release the more oxygen molecules.
03:15
So b option is correct here.
03:19
Partial pressure of carbonide oxide are lower...
