In Science, the study of blood is generally referred to as serology.

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

If a person was unable to absorb nutrients from the large intestine, would this be lethal? What about if one could not absorb fr
Zolol [24]
It would in fact be lethal. The main function of the digestive system is just that, to digest food. Both intestines play an important part in the digestive system( to digest and absorb all nutrients possible from stomach contents) The function of the large intestine is to absorb water, left over nutrients from the small intestine and, electrolytes. It would be equally if not more deadly if the small intestine couldn’t absorb nutrients. Since the small I intestine also plays an important role with providing the body with nutrients and other vital materials it would be deadly if you could not absorb anything. You would go into a state of malnutrition and would need to be treated immediately.
