Homeostasis describes how the Human Body keeps conditions within constant. It is the maintenance of the same internal environment and also allows the body to work at its optimum. Homeostasis is able to maintain water balance, blood sugar levels, ions and pH. All the factors mentioned are to remained constant. It also has the external factors for exercising as the Heart rate increases as well as Carbon Dioxide. This is because breathing in gets rid of the CO 2 and acquires Oxygen. Lastly, eating is also an external factor due to the glucose levels as when there is too much glucose, it is stored in the body. The major Organs involved in Homeostasis is the Brain, Muscles, Skin, Lungs, Pancreas as well as the Kidneys. An example as to how all the organs are maintained is that firstly the Kidneys remove the waste products by the process of metabolism by producing as well as secreting in Urine. They overall regulate the concentration and the volume of body fluids. The organ of the Liver control glucose regulation by storing in Glycogen and preventing low blood sugar levels. Also, the skin maintains Homeostasis by protecting and regulating body temperature, absorption of materials and water balance. It is the barrier for protecting inside the body. The Lungs however maintains gas exchange by eliminating Carbon Dioxide. The Pancreas regulates glucose in the body leaving with the Hypothalamus which forms the release and inhibition of hormones that prevents and begins the production of many other hormones throughout the Human Body. This has a Physiological effect.

The two systems which provide a major role within the process of Homeostasis is the Endocrine System and the Nervous System. The Nervous System is able to regulate and maintain Homeostasis by sending electrochemical signals throughout the Human Body. This coordinates and executes the voluntary and the involuntary processes which maintains Homeostasis. The Nervous System is comprised with fibrous axons which can stretch through the body and interconnect to coordinate activity. The Endocrine System however maintains Homeostasis to by producing hormones and maintain it by controlling the balance of water content, body temperature as well as blood glucose levels. If the blood sugar levels increase, the pancreas is able to detect it indicating that Insulin is released to act on the liver to allow excess glucose to convert into Glycogen. But once the blood sugar levels decrease, glucagon is released and acts on the liver, allowing the Glycogen to convert back into Glucose. Overall once the Endocrine System refuses to function, the Brain would not receive enough glucose and shuts down due to the fact that the blood needs a constant supply of it. The nervous system in homeostasis controls and maintains other parts of the human body as a deviation from the normal set point is able to act out as a stimulus and to a receptor. This is able to send in a nerve impulse to a regulating center in the brain. Finally, the endocrine system regulates the activity of the cells in the body. The release of the hormones in the blood can be controlled by the stimulus. The stimulus itself causes the increase or a decrease in the number of hormones that are secreted.

Mechanism of Homeostasis Control

To be able to sustain Homeostasis, the process of communication within the body is essential. To

summarize as to how the Homeostatic Control system functions:

Stimulus: is able to produce a change to a variable which is the factor that is regulated.

↓

Receptor: then is able to detect the change as this monitors the environment as well as how it responds

to change involving the Stimuli.

↓

Input: This source of information then travels along the Afferent pathway towards the control center

which determines the course of action and its appropriate response.

↓

Output: The information which is sent from the control center travels down towards Efferent pathway

and to the Effector.

↓

Response: A response from the effector is able to balance out the original stimulus so that Homeostasis

is maintained.

Afferent Pathways are able to carry nerve impulses towards the Central Nervous System. An example of this is that once you feel something which is unbearably hot, messages would travel through to the Afferent Pathway to the Central Nervous System. The Efferent Pathways however carry nerve impulses away from the Central Nervous System and towards the Effectors. Once the Human Body feel s heat, it travels through the Afferent Pathway and the CNS. This would then be able to interact with the Effector as well as travel down towards the Efferent Pathway which would eventually allow the person to instantly react with the hand which is too hot.

Homeostasis describes how the Human Body keeps conditions within constant. It is the maintenance of
the same internal environment and also allows the body to work at its optimum. Homeostasis is able to
maintain water balance, blood sugar levels, ions and pH. All the factors mentioned are to remained
