Question

If you had to put the organ systems (Endocrine, Blood, Cardiovascular, Respiratory, Digestive, Renal, Reproductive) in an order of importance for the role that system plays in maintaining homeostasis, how would you rank them (starting with most important)?  Provide justification for your ranking with specific examples of role for each organ system.  

Answer 1

The first one would be the endocrine system. There are numerous glands and hormones produced from these glands that are necessary for maintaining homeostasis. If endocrine glands stop functioning, the entire homeostasis would be damaged.

The second one is the CVS system. The heart is the principal organ here and is primarily associated with supplying oxygen, nutrients, etc to all tissues and will help in the elimination of metabolic wastes maintaining homeostasis.

The third one would be the circulatory system or blood. The blood is one that acts as a medium in transporting every product as per cell demands from its source to the target.

The fourth one would be the digestive system. This system is the one which breaks down the food products we consume and obtain nutrients so that it can be transported to the cells.

The fifth one would be the respiratory system. This system has lungs as the primary organ which transports oxygen and carbon dioxide across cells and tissues. Oxygen is necessary for the release of energy for performing various internal body activities.

The sixth one would be the renal system. The kidney is the primary organ here and helps in the elimination of all metabolic wastes from the body that accumulates in blood from time to time.

The seventh one is the reproductive system. The hormones produced from this system has several functions in the body and is primarily associated with giving birth to a new progeny.
