Endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulates the activity of cells or organs. These hormones regulate the body’s growth. The hormones are released into the bloodstream and may affect one or several organs throughout the body. 2. Define homeostasis and explain its role in the endocrine system? Homeostasis the tendency toward a relatively stable equilibrium between interdependent elements especially as maintained by phycological process. The hypothalamus plays a significant role in the endocrine system. It is responsible for maintaining the body’s internal balance, hypothalamus stimulates or inhibit many of your body’s key such as body temperature, sleep cycles, and body weight. 3. Explain a negative feedback mechanism and provide an example in the body? …show more content…
Negative feedback mechanism is more common to maintain a target level. For example, negative feedback loop is when hormone concentration increases. In the time when hormone concentration decreases the rate of production increases. An example, of negative feedback loop is when there are elevated levels of thyroid inhibits TSH release. This then increases levels of Ca++ inhibit parathyroid hormone. This decreases glucose levels and then release insulin. 4. Describe the cell signaling mechanism and role of insulin in glucose uptake be cells? Mechanisms that regulate insulin-mediated glucose uptake may provide clues to the underlying abnormalities in insulin resistance and diabetes. Glucose traveling into most tissues is achieved by the action of molecules called glucose transporters. The molecules transport glucose by facilitative diffusion down concentration gradients, which leads to energy-dependent uptake of glucose in the gut or kidney 5. Compare Type 1 and Type 2 diabetes and explain another
It is very important for organisms to maintain homeostasis because when it’s disrupted that could cause other systems to go out of balance, which may result in damage in the organism. Homeostasis can be disrupted in many ways like when a human is sick. When a human is sick it starts in the immune system and depending on the intensity of the sickness it can cause other things like water balance and body temperature to go awry which would affect other systems. Another scenario when homeostasis is disrupted is when a plants water level is low and it wilts...
While the respiratory and cardiovascular systems are most reliant on one another, all body systems require a functioning circulatory cycle in order to thrive. Blood circulation and consistent transfer of oxygen to cells is required to maintain cell and tissue life. Disturbances to this process will cause cells and tissues to die (Red Cross 48). This state of balance and functioning body systems is referred to as homeostasis, defined as a “condition of equilibrium in the body’s internal environment due to constant interaction of body’s many regulatory processes” (Tortura 8). Changes or disruptions to homeostasis are regulated by the Endocrine and Nervous systems of the body. The endocrine system is made up of glands placed throughout the body
This is monitored by the cells within the Islets of Langerhans, which is located in the control (the pancreas). After skipping a meal or tough physical exercise blood glucose concentration decreases. Alpha cells in the islets detect this drop and are stimulated to secrete glucagon. Glucagon is a polypeptide hormone which influences an increase in blood glucose concentration. Glucagon travels through the bloodstream until it reaches glucagon receptors which are predominantly found in the liver, as well as, the kidneys. Glucagon stimulates the breakdown of stored glycogen to be released into the bloodstream as glucose. It also stimulates the conversion of amino acids into glucose and the breakdown of fat into fatty acids. These effectors cause an increase in blood glucose levels back towards the normal. This increase in blood glucose concentration is detected by the alpha cells which then stop the secretion of
Our body obtains the energy by digesting the carbohydrates into glucose. Volumes of glucose are required by the body to create ATP. ATP is short for 'Adenosine Triphosphate ' and is an energy carrier. When we consume too many carbohydrates our body produces a lot of glucose and as a result blood glucose levels rise and sometimes they may rise over the normal range of blood glucose concentration. To bring it back within the healthy range, the homeostatic system of blood glucose regulation is used. The blood flows through the pancreas where the beta cells, receptors, detect the high blood glucose level. To counteract this stimuli beta cells alert the control centre, which are also the beta cells located in the islets of Langerhans in the pancreas. The secretion of insulin has to be done quickly but can only be carried out when insulin gene is switched on. Turning on the insulin gene switch can take 30 minutes to an hour therefore, the production of insulin by beta cells are done in advance and are packaged in vesicles right until blood glucose rises. Glucose comes into the beta cell to trigger the vesicle that contains the insulin to move towards the plasma membrane and fuse. This releases the insulin into the bloodstream where they are distributed throughout the body and only affect specific target cells. The receptor, a protein, on the target cell’s plasma membrane recognises and connects
There is a variety of homeostatic procedures that the internal environment maintains within an acceptable limit. Without the control of the homeostatic system the body suffers various issues. These issues like cellular failure can
Homeostatic mechanism use feedback loop. The detection - correction or feedback systems that the body uses to maintain homeostasis are constantly detecting internal or external conditions. These homeostatic mechanisms then evaluate the conditions to determine whether or not they represent any deviations from the normal. If conditions are outside of the optimal functioning range, the mechanisms take corrective action to bring the body back into balance. A good example of a negative feedback mechanism is a home thermostat (heating system). The thermostat contains the receptor (thermometer) and control center. If the heating system is set at 70 degrees Fahrenheit, the heat (effector) is turned on if the temperature drops below 70 degrees Fahrenheit. After the heater heats the house to 70 degrees Fahrenheit, it shuts off effectively maintaining the ideal temperature.

Cortisol is in the class of hormones called glucocorticoids and affects almost every organ in the body. One of the most important functions of cortisol is to help regulate the body’s response to stress. Cortisol is also responsible for other necessary functions including: helping to maintain blood pressure and cardiovascular functions, helping to slow the immune system’s inflammatory response, helping to balance the effects of insulin in breaking down sugars for energy, helping to regulate the metabolism of proteins, carbohydrates, and fats, and helping to maintain proper arousal of sense of well being. The amount of cortisol is precisely balanced and regulated by the brain’s hypothalamus.
The endocrine system is very dynamic and has ties to most, if not all of the other major systems of the body. It is responsible for production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms, they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth, development, reproduction, and behavior, among many others as well.
If homeostasis is not maintained it will result in illness disease and even death, as without each functional part of the body working efficiently together, the body cannot operate at a sufficient level to maintain survival.
Glucose is the primary source of energy for the cells and consequently is necessary for all cellular functions that require energy. Facilitated diffusion plays a significant role in the management of concentrations of glucose, both intracellular and extracellular, providing a balance of glucose in the cells that when poorly utilized upsets the body’s homeostasis.
Homeostasis is a system that is needed to regulate the internal parts of the body such as temperature or bone homeostasis. The process of homeostasis is important to ensure the internal body is kept stable and to keep the conditions within the body the same as this allows the body to function properly.
It is the idea that the mind and body are not separate entities. Rather, they are intricately connected, interacting with each other in many ways. The body's three main regulatory systems are the central nervous system (which includes the brain), the endocrine system (which produces hormones), and the immune system. These three systems work together and affect one another. Researchers who study the mind-body connection examine these interactions, and are particularly interested in the effects of emotions and thoughts on physical health.
Immediately after a high carbohydrate meal, Insulin secrets rapidly due to glucose absorption into blood. This insulin act on many tissues in body and insulin turn causes rapid uptake, storage and use of glucose almost all issues of the body, but especially by the muscles, adipose tissue and liver. (8)
...culatory system. Pituitary gland is a growth hormone that helps in mertabolism and develops reproductive organs. The thyroid controls metabolsim on the rate that the body breaks down food. Adrenal gland secretes many hormones including adrenaline which prepares the body to react in a stressful situation. The pancreas produces digestive enzymes and insulin. Ovaries produce ova and estrogen. Testes produce sperm cells and testosterone. To stay healthy you should get a regular medical check-up, eat a well-balanced diet, sleep at least 8 hours, and decrease stress in your life. Some problems are growth disorders, diabetes, and obesity. Puberty begins at different times for girls then boys. Girls start around ages 9-13 and boys are ages 10-15.
Lastly, blood is involved in maintaining homeostasis by negative feedback loops such as temperature regulation, blood pH, blood glucose levels, and blood pressure.
