How does the brain live?
The brain lives when it has a constant supply of blood glucose and oxygen.
Is cerebral blood flow regulated by intrinsic autoregulatory mechanisms?
Yes, cerebral blood flow is regulated by intrinsic autoregulatory mechanisms in the brain. These mechanisms ensure a relatively constant blood supply to meet the brain's metabolic demands, even when there are fluctuations in systemic blood pressure. Autoregulation helps to maintain stable oxygen and glucose delivery to the brain, supporting its constant function.
Why is it important for your blood pressure to stay at a constant level?
Keeping your blood pressure at a relatively constant level is likely to prevent strokes and other vascular accidents.
What is the term for the ability of the body to maintain a fairly constant blood-sugar level in spite of variations in intake of sugar?
The term for the body's ability to maintain a fairly constant blood-sugar level is called "glucose homeostasis." This process involves a complex interplay of hormones like insulin and glucagon to regulate the amount of glucose in the blood.
What is the maintence of homeostasis?
it is the maintenance of the internal environment of the body like keeping the blood glucose level constant or keeping the body temperature constant
How during a marathon race the blood glucose concentration stays fairly constant but the mass of glycogen in the liver decreases?
During a marathon, the body primarily uses glycogen stored in the liver and muscles for energy. As the race progresses, glycogen stores deplete, leading to a decrease in liver glycogen levels. However, blood glucose concentration remains relatively constant due to the liver's ability to release glucose into the bloodstream through gluconeogenesis and glycogenolysis, as well as the hormonal regulation of insulin and glucagon. This mechanism ensures that the muscles continue to receive a steady supply of glucose for energy, despite the declining glycogen reserves.
What is a disorder of blood glucose regulation?
A disorder of blood glucose regulation refers to conditions where the body has difficulty maintaining stable blood sugar levels. This can include disorders like diabetes, hypoglycemia, or impaired glucose tolerance. Proper management and monitoring of blood glucose levels are essential to prevent complications associated with these disorders.
How does glucose and oxygen travel to the brain?
Glucose and oxygen are transported to the brain through the bloodstream. They are carried in the blood vessels and are delivered to the brain cells through a network of capillaries. The brain relies on this constant supply of glucose and oxygen to function properly.
What substance needs to be maintained to give cells a constant supply of energy?
oxygen and glucose
Summarize easy explain how glucagon and insulin work together to maintain a relatively constant blood sugar level?
Glucagon is a hormone that converts glycogen stored in the liver into Glucose (Sugars). When our blood sugar level fall below normal, glucagon will convert the glycogen stored to sugar (Glucose) to ICREASE our blood sugar levels: Glucagon is used when blood sugar levels fall below normal and glucose is needed to raise the levels. Insulin is necessary for the body to convert sugar, starches into energy needed for daily usage, Insulin is a hormone that is produced by the pancreas and released into the bloodstream when glucose (Blood Sugar) levels are on the rise, When the body has a high blood sugar, Insulin in released, breaking down the glucose and LOWERING the blood sugar levels.
What blood test is glrand for?
GLRAND is not a commonly recognized term in relation to blood tests. It is possible that you meant "GLU" or "GLUCOSE," which refers to a blood test measuring glucose levels to assess diabetes or metabolic conditions. If GLRAND refers to a specific test, please provide more context for accurate information.
What does mg percent mean in glucose measurements?
Mg percent in glucose measurements refers to the concentration of glucose in a solution, expressed as milligrams of glucose per 100 milliliters of solution. This unit is often used in medical contexts to indicate blood glucose levels, such as in diabetes management. For example, a glucose measurement of 90 mg percent means there are 90 milligrams of glucose in every 100 milliliters of blood.
