In our body the blood glucose levels are regulated by a negative feedback system. The negative feedback system is a type of homeostatic system, and allows the body to maintain homeostasis. It detects changes, using the sensor, (which in glucose regulation is the pancreas recognizing the change in levels of glucose in the blood), caused by the stimulus. Then the control centre (pancreas) which is the response to the change, sends a message to the effector (liver) to counteract the change. The effector acts about to bring the body to its original set
1. Explain the essence of homeostasis. Why is it crucial for the bodily systems to maintain homeostasis? Homeostasis is the maintenance of a constant internal environment. Control systems throughout your body maintain automatic temperature & water at a steady pace, which requires cells to function.
Decreased blood flow to the kidneys activates the renin angiotensin system. Renin is released, which activates angiotension to produce angiotensin I, which is then converted to angiotensin II. Angiotensin II is also a potent vasoconstrictor, which causes both arterial and venous vasoconstriction. Angiotensin II also stimulates the adrenal cortex to release aldosterone, which results in sodium and water reabsorption and potassium excretion by the kidneys. The increase in sodium reabsorption raises the serum osmolarity and stimulates the release the antidiuretic hormone ADH from the posterior pituitary gland.
Describe how the hormones of the pancreas regulate the concentration of glucose in the blood (4 points). Insulin is used by the pancreas in response to when the body’s level of blood glucose is too high, and glucagon is inhibited. Insulin performs the job of taking glucose into the liver and helps store glucose as glycogen within the body. When the blood glucose level of the body gets to low the body will inhibit the secretion of insulin, so that glucagon can do its job. What glucagon does is it takes the stored glycogen and lets it be released back out into the bloodstream so the body can have more energy.
11.3.Glucagon Glucagon is a hormone produced by the alpha cells of the pancreas. Glucagon possesses adverse effects of insulin. So in regulating the blood glucose level, the pancreas produces both insulin and glucagon. This hormone is produced after the meal and during your sleep time. It is the glucagon that helps the liver to break down the food you eat to manufacture glucose.
Biofeedback may be used to improve health, performance, and the psychological changes that often occur in conjunction with changes to thoughts, emotions, and behaviour. Biofeedback therapy may not work on serious medical conditions, but works for minor pains and nuisances like migraines or headaches. Body The
Why do you think it is important to screen for dyslipidemia before exercise? It is important to screen individuals for dyslipidemia, due to the risk of coronary heart disease and other cardiovascular diseases. Furthermore, individuals who have high levels of triglyceride or cholesterol levels can experience insufficient amounts of oxygen to the tissues, heart, and the brain. Also, these individuals are at an increased risk for myocardial infarctions and stroke. 7.
Dear Editor, there are many reasons why it’s important to get vaccinated. One reason why it’s important to get vaccinated is because vaccines will keep your body healthy. Another reason why it’s important is because you put the health of other people at risk if you get sick. Lastly, it’s important to get vaccinated because you’re putting yourself at the risk of dying if you don’t. Vaccinations will keep your body healthy.
The adrenals are known for making the hormone adrenaline but also, they make the corticosteroids which affect your metabolism and sexual function. The pancreas is part of the the digestive system and the endocrine system. It makes the hormones insulin and glucagon. These help ensure you have the right amount of sugar in your bloodstream and your cells. If you don 't make any insulin, which is the case for people with type one diabetes, your blood sugar levels can get dangerously high and if the body makes some insulin but not enough, that is type two diabetes.
