In order to answer this question, let's talk about the bore and the halting effects.
00:05
In this case, first let's talk about the borer effect.
00:11
Okay, so this bore effect occurs.
00:14
Specifically, it occurs at the metabolizing tissue.
00:17
Okay, so you're going to have a little of the tissue at the tissue level.
00:22
And what happens with this board effect? well, practically, it's going to describe the release of oxygen.
00:28
Remember that your hemoglobin is the molecule or the protein that is going to hold the oxygen molecules within it.
00:35
What the more effect is going to describe is the decrease in the oxygen affinity of hemoglobin in response to a decreased blood ph resulting from increased levels of carbon dioxide concentration in the blood.
00:48
For example, when, if this is your hemoglobin molecule, suppose, like this, you have oxygen, oxygen, oxygen, oxygen, and oxygen.
01:03
So in this case, your hemoglobin has high affinity for oxygen because your hemoglobin is binding oxygen.
01:10
Okay, but what happens during the more effect? practically during the more effect is that your hemoglobin molecule is going to decrease affinity for oxygen, it means the oxygen molecules are going to be released.
01:20
And this is, and this occurs because of high amount of carbon dioxide levels.
01:28
High carbon dioxide levels that are going to decrease the ph of the blood.
01:36
Okay, so practically the high levels of carbon dioxide are going to make the hemoglobin infinity for hemoglobin dioxide to decrease.
01:45
And hence, oxygen is going to be released to the tissues.
01:49
In this case, this is why it occurs in the tissues, because what you want in the tissues is to release the oxygen molecules.
01:55
You want your hemoglobin to decrease its affinity for oxygen, in order for oxygen to be able to be released to that tissues.
02:03
And you don't want this to happen in the lungs, because if this happens in the lungs, then oxygen is going to be released to the lungs.
02:10
It means you're going to exhale oxygen, and you don't want that.
02:13
Okay.
02:13
So practically, in the tissue you want, a decrease affinity of hemoglobin for oxygen, while in the lungs you want an increased affinity of oxygen or for hemoglobin for oxygen in order to hold the hemoglobin or the oxygen with the hemoglobin molecules.
02:34
Now, you have, at the other hand, the halting effect.
02:40
Okay, the halting effect.
02:41
And this occurs, or it is kind of the opposite.
02:45
Okay, it happens in the lungs...
