Regulation of Blood Pressure and Blood Volume One way the body regulates blood pressure and blood volume is through the body’s use of baroreceptors‚ a mechanoreceptor of the nervous system. If there were low arterial blood pressure‚ the baroreceptors in one’s blood vessels could detect this. One’s baroreceptors in the aorta and carotid sinus of the cardiac system are constantly monitoring blood pressure. They send messages containing any changes through the central nervous system to the medulla oblongata

Explain how blood sugar levels are regulated in your body. Blood sugar level (also known as blood glucose level) is the amount of glucose (sugar) in the blood. The amount of glucose in the blood is expressed as millimoles per litre (mmol/l). Blood sugar levels are tightly regulated in the human body. Glucose‚ transported via the bloodstream‚ is the primary source of energy for the body’s cells. The levels of glucose in the blood are monitored by the cells in the pancreas. If the blood glucose level

carbohydrates on blood glucose levels INTRODUCTION There are two types of diabetes which includes diabetes inspidus however the disorder most commonly associated with the generic term ‘diabetes’ is diabetes mellitus. Diabetes mellitus is condition whereby blood sugar levels are far too high due to poor metabolism. There are two variations of the disorder which are Type 1 and Type 2 Diabetes Mellitus. Type 1 diabetes occurs as a result of the body’s inability to produce insulin. A person suffering

Glucose is one of the key nutrients required in the body. However‚ its amount in the body has to be regulated and maintained in a very narrow range. This regulation of glucose is performed by insulin hormone. Insulin is secreted at the pancreas and hence is referred to as pancreatic endocrine hormones. Insulin is secreted by beta cells‚ which are normally located at the pancreas. When the amount of glucose in the blood increases‚ the stimulus for insulin secretion triggered. The insulin level secreted

GLUCAGON -has a major role in maintaining normal concentrations of glucose in blood‚ and is often described as having the opposite effect of insulin that is‚ glucagon has the effect of increasing blood glucose levels while insulin lowers blood glucose levels. The pancreas releases glucagon when blood sugar glucose levels fall too low -linear peptide of 29 amino acids. -Glucagon causes the liver to convert stored glycogen into glucose‚ which is released into the bloodstream. -Glucagon

in a toxic environment. Much of what we consume is simply not good for our bodies-it builds up and eventually damages our health. Antioxidant vitamins-vitamins C and E‚ and beta carotene-may be what we need to "clean up" our systems. Excess sugar in the bloodstream can have very serious side effects. The extra sugar impedes blood flow‚ causing wounds to heal more slowly and infections to become more virulent. Just how this excess sugar causes damage remains a topic of debate. One plausible mechanism

Blood Sugar Insulin: Insulin is a protein hormone that facilitates the transfer of glucose from the blood into cells. Insulin lowers blood sugar by stimulating the liver to store glucose as glycogen. The release of insulin is nutrient-regulated – it is typically released after a meal. Glucagon: The release of glucagon is nutrient-related; typically released when blood sugar drops‚ during times between meals. (HINT: Think glucose-gone for glucagon.) Glucagon stimulates the liver to break
