1. UNDERSTANDING THE PRINCIPLES OF HOMEOSTASIS
Homeostasis is basically concerned with the preservation of a steady internal environment as a
reaction to a change in the external environment. The role of hormone is predominantly
significant in this system. These constitutes of protein that are released by the glands in the body
into the bloodstream, where they get to the targeted cells. A specific hormone that fits a specific
receptor protein brings the change in the cell. Overall, the homeostatic is basically concerned
with the internal consistency.
1.1 Principles of homeostasis in humans
The basic principles of homeostasis are to maintain a constant condition in case it deviates from
the set point or norm, the corrective measures to bring back the set norm is regulated by the
entity. In the same way, the homeostasis controls various factors in order to keep them constant
such as water, body temperature, blood pressure, nutrients such as glucose and ions, and PH
despite the changes in the external environment or the activities of the body (Pang et al., 2014).
The homeostasis system is designed to function by identifying the changes that are occurring in
the set points or norms and initiate the corrective measures to offset the changes occurring.
The system incorporates in it the sensor which becomes active when the system actual condition
deviates from the desired condition; it serves as a device which assists in reducing the difference
in the conditions for which it uses and effector for taking the desired action. For instance, if the
amount of water within the body differs from the set level, it can cause disruptions in the
metabolism. Similarly, if the temperature level changes from the set point, the structure of
proteins, as well as enzyme, get affected which result can be disastrous and more.

1.2 Relationships between homeostasis, growth, and development
The homeostasis shares a prime relationship with the growth and development. The homeostasis
involves each system in the body for fulfilling the basic needs of the individual. For instance, the
energy required for maintaining a normal body function for homeostasis is provided by foods
and the oxygen. The energy supply in the assistance for carrying out the functions that are
essential for the growth and development of the body. For example, the growth and development
in the child may be affected if he is not provided with the required food, the condition results in
malnutrition which reduces his capacity for tackling the infections and diseases which results in
failure for them to thrive.
1.3 Homeostasis challenges
The human body is a biological system that always faces some challenges in its growth despite
the continuous pert
