Human body is made of ten different systems. All the systems require support and coordination of other systems to form a living and healthy human body. If any one of these systems is damaged, human body will become unstable and this lack of stability will ultimately lead to death. The instability caused by damage of one system cannot be stabilized by other systems because functions of one system cannot be performed by other systems. Knowledge of human body systems is very important for a medical professional because it is the base of all medical sciences and clinical practices. Although, generally, the structural aspects of human body systems are studied in anatomy and the functional aspects are studied in physiology but it is very important to have a coordination between the two subjects because knowledge of structure is incomplete without the knowledge of function and the knowledge of function is incomplete without the knowledge of structure.

Atmosphere and Hydrosphere are the answer. The atmosphere is a layer of gases that surrounds in the planet or other material inside the body that is held in place by the gravity of that body. There is also Atmosphere in earth or what we called Air, it is also a layer of gases. It is the whole mass of air that surrounds the earth so that we can breathe freely. Earth atmosphere contains 78% nitrogen, 0.9% argon, 21% oxygen and 0.03% carbon dioxide. Hydrosphere in the other side is all the water on the earth’s surface example are lakes, seas and sometimes including water over the Earth’s surface like clouds.

In humans, the embryonic and fetal forms of hemoglobin have a higher affinity for oxygen than that of adults. Why is this the ca

Bezzdna [24]

In humans, the embryonic and the fetal forms of haemoglobin have a higher affinity for oxygen than that of adults this is because non-identical genes produce different versions of globin during development. So the correct option is A.

<h3>What is meant by oxygen affinity? </h3><h3> </h3>

The amount of oxygen delivered to the cells will depend on the haemoglobin's oxygen affinity.

Oxygen affinity is defined as the relationship between the saturation of haemoglobin oxygen, represented by SaO2 and the oxygen tension, represented by PaO2. This relationship is plotted by a dissociation curve which is S-shaped.

Thus, in the embryonic the fetal form, haemoglobin has a higher affinity for oxygen.

Therefore the correct option is A.
