Hematopoiesis refers to the formation of blood cells within the red marrow cavities of certain bones

True

Explanation:

Hematopoiesis is the production of every types of blood cells as well as blood plasma. Simply put we can define this as the way through which blood cells are manufactured by the body. This process happens in different body organs and tissues like the liver and spleen. In humans, it starts from the yolk sac, to the liver and then bone marrow.

currents is the correct answer.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
