The brain is able to overcome negative feedback in these localized systems and continuously evaluate the body's internal set-points. By doing so, the body can regulate its resources and energy storage efficiently. Another key component of allostasis is the brain's perception and subsequent adaptation to chronic stress.
The central nervous system (brain and spinal cord) plays a crucial role in the body's stress-related mechanisms. Whether one should interpret these mechanisms as the body's response to a stressor or embody the act of stress itself is part of the ambiguity in defining what exactly stress is.
There are two types of functional systems: System of the first type provide homeostasis due to internal (existing) resources of the body, inside its boundaries (e.g. blood pressure). System of a second type supports homeostasis due to a change of behavior, interaction with the outside world and are the basis of different types of behavior.
The biological basis of the study of physiology, integration refers to the overlap of many functions of the systems of the human body, as well as its accompanied form. It is achieved through communication that occurs in a variety of ways, both electrical and chemical. [8] Changes in physiology can impact the mental functions of individuals.
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
Although there is little research in regards of break-induced replication, it is known that it is a one-ended recombination mechanism, where only of the one ends of a DSB will be involved in strand invasion. [14] This means that unlike DSBR, BIR does not link back to the second DSB end after the strand invasion and replication. [14]

The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up ...
