The partial oxygen pressure (pO2) should be high for the maximum loading of hemoglobin with the oxygen.
Hemoglobin is a quaternary protein that transports oxygen in the blood. Hemoglobin is made up of four heme subunits and an Iron atom. Blood oxygen is bound to the hemoglobin in red blood cells. One molecule of hemoglobin binds the four oxygen molecules and forms the oxyhemoglobin.
The partial pressure of the oxygen is an important factor that determines the binding affinity of oxygen to the hemoglobin. The higher the partial pressure of oxygen the more oxygen binds with the hemoglobin. The hemoglobin binds oxygen rapidly in the pulmonary capillaries of the lungs due to higher partial pressure of oxygen.

serves as a source of neural stem cells (NSCs) in the process of adult neurogenesis.
No till, or conservation planting, is the method of planting crops that disturbs the soil. It also generally has plants that cover as little as possible.
When the physician tells Dennis there may be a defect in the valve between an upper and lower chamber of his heart, he knows for sure that the defect is in the atrioventricular valve.
<h3>What are the two functions of the heart?</h3>
The two functions of the heart are as follows:
- It helps in the movement of blood throughout the body.
- It controls the rhythm and speed of the heart rate as well as blood pressure.
The Atrioventricular valve typically functions in order to prevent the blood from flowing back into the region of the atria. They are just located between the atria and the ventricles.
Therefore, a defect in the atrioventricular valve is found when Dennis suffers from a defect in the valve between an upper and lower chamber of his heart.
