Essay on homeostasis

This means that there will be no sugar in the blood or there will be excess sugar in the blood, thus affecting the fluid intake into the body.

Write an essay on Homeostasis

Homeostatic imbalance can lead to diabetes and dehydration amongst other problems. During exercise, a change in sympathetic activity is the predominant mechanism by which speeding and slowing of the heart is achieved. If insulin is disrupted in the body it leads to other health complications.

If the temperature goes to high, you might get overheated and get dizzy; this is why your body sweats, to cool off.

Responding to this stronger signal, the respiratory Essay on homeostasis increase both the speed and depth of breathing. Fluids could increase or decrease depending on the water intake of a person, thus fluid levels are dynamic and not set in the body.

During exercise especially training that requires explosive movements sprinting it is common for sweating to occur and for the body to be feeling tired due to the build-up of lactic acid from anaerobic respiration. When you exercise, your body responds to the activity by releasing hormones that cause your body to increase blood glucose levels.

What would be wrong with a set point, rather than working with a range of values? This is due to the autonomic nervous system controlling the heart rate and the internal receptors picking up any deviances.

How does Homeostasis Work? It causes each heartbeat to increase in strength as well causing an increase in heart rate. If this persists for a long time it leads to health complications like diabetes and at some point a person has to inject themselves with insulin to keep the body functioning.

If our body is Essay on homeostasis to maintain homeostasis, we get weaker and in the worst case scenario, we effectively die. The abdominal muscles are the muscles help move your diaphragm during inhalation and give you more power to empty your lungs.

For growth to take place there must be a balance that is maintained in both body temperature and body fluids. When you inhale, your diaphragm contracts and moves downward, away from your chest cavity, and the pressure in your lungs drops, when we exhale your diaphragm relaxes and shifts upward into your chest cavity.

Not always does the body temperature go up but also at times it goes down. The hormone ensures that growth take place in a regulated manner, so that over growth is not experienced and at the same time stunted growth is not experienced. This is how diabetes occurs.

Homeostasis and heart rate Homeostasis is responsible for managing the heart rate. The body has to have the levels of glucose which is blood sugar maintained at good levels. In response to hotter conditions, the body may also react by producing sweat, which serves as a bodily cooling system. For example when we do vigorous exercise our body breaks down muscles fibres and catabolism causes them to rebuild again causing our body temperature to rise due to the heat being generated from the reaction.

Especially at teenage, when people reach their puberty, the growth hormone is responsible for the changes that occur in the human body and is termed as growth. We try to survive and keep the homeostatic function going on by keeping warm.

Heat is produced during metabolism, so an increase in metabolic rate also increases heat production. Insulin plays the role of a catalyst, in the conversion of glucose to glycogen to glucose and in the conversion of glucose to glycogen.

When the climate changes and the temperature in the external environment is low, for example when it is extremely cold.

Insulin is a hormone that handles blood sugar and is released whenever the blood sugar goes up so that the body can function normally. The brain and nervous system both play a major role in controlling homeostasis mechanisms. This occurs through a process called gluconeogenesis or glycogenesis that happens in the liver.

You might start to feel weaker and less energetic if your glucose levels get to low whereas if they are too high, you might become really hyper. The rate of respiration can be influenced by the level of carbon dioxide in the blood, which makes the chemoreceptors aroused, thus leading to impulses being sent by the medulla to the intercostals nerves to increase the breathing rate.

Inhalation typically is an active movement, and it involves muscle contraction from your diaphragm, abdominal muscles and intercostal muscles to be maximally effective.

Insulin restores normal levels of glucose in the blood by signalling body tissues to take up glucose for energy, or to convert glucose to glycogen and lipids as future energy stored in the liver, muscle and fat cells. Its nerves are the cardiac nerves.

If this is not maintained at the right levels under which the body can function, then the person is prone to diseases like diabetes which cause health complications. Homeostasis and body temperature Thermoregulation is the term used to describe homeostasis and temperature regulation, which is governed by the hypothalamus gland within the brain, both the hypothalamus and receptors in the skin help monitor changes in external and internal temperature, activating the negative feedback system when temperatures exceed or fall beyond normal levels.

Haigh Survival in the outside world At times the external environment pushes our body to the limit, in such a way that the body by itself may not be able to handle. Heat is generated from a variety of sources.Homeostasis - Elaine’s reaction to the high winds and extreme cold is because of her body maintaining homeostasis.

Homeostasis is the ability of the human body to maintain its internal environment at equilibrium, or in other terms, to keep the body at a.

Homeostasis Essay - Homeostasis Homeostasis works to maintain the organism's internal environment, where the body's processes are able to function at a level that would allow life to continue in that organism.

The three systems which are controlled by homeostasis are the respiratory, cardiovascular, and muscular systems. Oct 22,  · Find essays and research papers on Homeostasis at We've helped millions of students since Join the world's largest study community. Homeostasis essays The human body's ability to maintain a constant environment is essential to its survival.

This capability is referred to as homeostasis. Homeostatic mechanisms keep the body near a set point, based on the sensitivity of central nervous system nuclei, which is an ideal value.

Disclaimer: Homeostasis is of utmost importance for the cells of the body to function really well. This explains the complexity of the systems that work out homeostasis. If you are the original writer of this essay and no longer wish to have the essay published on the UK Essays website then. Homeostasis is best defined as a state of equilibrium in which the internal environment of the body remains relatively constant and/or is maintained.

As is the case with the body, any government which wishes to survive must also maintain homeostasis. 4/4(3).
