"Emphysema and the Endocrine System" is a good example of a paper on the endocrine system.   Homeostasis is the principle through which a cell, tissue, or an organism regulates and or balances its internal functions and conditions. Functions include body fluids’ chemical composition to maintain health and functioning based on zero dependence on outside conditions. These organisms or cells usually maintain their associated homeostasis by establishing a system of physiological monitoring of its internal conditions and appropriately responding whenever such conditions record a deviation from their optimal levels. Homeostasis is also the critical ability of the cell or body to seek and or maintain equilibrium condition or stability within its internal environment in dealing with variations outside the body. There are certain differences in the way animals and humans achieve homeostasis.

Both have separate systems of managing their optimum body physiology to standard or optimum levels. For instance, warm-blooded animals maintain constant body temperature in whatever state of their immediate environment. At the same time, humans have systems of mechanisms for homeostatic regulation involving sweating to control high internal temperatures or shivering when the internal temperatures reduce to produce heat in the body. The work of the organ system in maintaining homeostasis Human body organs function as a common unit and system.

There are physiological coordination systems through which veins, arteries, blood capillaries, and sensory neurons coordinate the linkages between the organs.   The body organs involved in the homeostasis include the respiratory system consisting of the lungs, kidney, and heart. It encompasses the blood circulatory system that includes the heart, lungs, and kidney (Chiras, 2013). There are internal connections of organ systems and their internal functions for stability and equilibrium in the human body systems. Starting with the heart, it pumps deoxygenated blood to the lungs for oxygenation purposes.

This blood goes to the heart after supplying nutrients and oxygen within the body thereby rendering it deoxygenated.   The lung that contains oxygen from inhalation oxygenates the blood and then pumps it back to the heart for supply to the body parts. The main purpose of the blood from the lungs in the support of physiological processes through nutrients supply. This blood from the lungs has the capability of supplying nutrients to other body parts.   The lungs release carbon dioxide from the body.

It is in the lungs that the exchange of air takes place. Carbon dioxide gets back into the lungs from the blood capillaries carrying deoxygenated blood for release into the outside environment. The exchange of air ensures that oxygen gets to the bloodstreams while carbon dioxide gets out of the bloodstream (Starr & McMillan, 2013). The kidney performs an excretory function, together with the skin to remove wastes from the body in form of nitrogenous wastes.

On its part, the alimentary canal acts as the channel through which food nutrients find their way into the body’ s physiology. The food nutrients support the growth and development of the body while also maintaining the physiological processes of the organ systems.   Blood pumped by the heart carries and transports the food to other target parts of the body for growth and development and nutrients supply to maintain a normal function of the body system despite the environmental difference internally and externally.
