How is calcium regulated in the blood?
The body's calcium level is regulated by a gland in the endocrine system, it is called the Parathyroid Gland.
Single most important factor influencing potassium ion secretion is?
The single most important factor influencing potassium ion secretion in the kidneys is the level of potassium in the blood. High blood potassium levels stimulate the secretion of potassium ions, while low blood potassium levels inhibit its secretion.
What is an example of negative feedback?
An example of negative feedback would be a secretion of greater amount of insulin to lower the blood sugar level, and then secretion of greater amount of glucagon to increase the blood sugar level, and then a secretion of a greater amount of insulin to lower the blood sugar level..... etc.
How the level of thyroxine in the blood affects the secretion of hormone TSH?
High levels of thyroxine in the blood negatively feedback to the pituitary gland, reducing the secretion of thyroid-stimulating hormone (TSH). Conversely, low levels of thyroxine signal the pituitary gland to increase TSH secretion to stimulate the thyroid gland to produce more thyroxine.
Why a starved liver has less glycogen then a well fed liver?
The blood-glucose level begins to drop several hours after a meal, leading to a decrease in insulin secretion and a rise in glucagon secretion; glucagon is secreted by the α cells of the pancreas in response to a low blood-sugar level in the fasting state. In same way,insulin signals the fed state, this fed condition leads to the secretion of insulin, which is one of the two most important regulators of fuel metabolism,the secretion of the hormone insulin by the β cells of the pancreas is stimulated by glucose. It stimulates glycogen synthesis in both muscle and the liver and suppresses gluconeogenesis by the liver.
Is blood pressure regulated by positive or negative feedback?
Aldosterone is both responsible for absorption of sodium and excretion of potassium. If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood. If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-
Sodium level in blood 126 is it dangerous?
Is sodium level in blood 129 dangerous
What effect does excess secretion of epinephrine do to the blood glucose level?
HYPERGLYCEMIA. because epinephrine increases the blood glucose level by increasing glycogenolysis.
How is calcium regulated in the blood?
The body's calcium level is regulated by a gland in the endocrine system, it is called the Parathyroid Gland.
How Hormonal Secretions Are Regulated?
Most hormone secretions are regulated by negative feedbacks. The 3 main feed backs are:1)(Blood level of certain chemicals controls hormone secretion) Blood composition; Ex: blood glucose levels control the insulin secretion.2)(Hormones controlled by nervous system) Neural control; Ex: Epinephrine is release from adrenal medulla as result of nervous system stimulation.3)(Hormone secretion controlled by other hormones) Hormonal control; Ex: hormones from pituitary gland act on the ovaries and testes causing release of sex hormones.Source: Seeley's Essentials of Anatomy and Physiology (seventh edition)
Single most important factor influencing potassium ion secretion is?
The single most important factor influencing potassium ion secretion in the kidneys is the level of potassium in the blood. High blood potassium levels stimulate the secretion of potassium ions, while low blood potassium levels inhibit its secretion.
Is 142 a safe sodium blood level?
yes
Why does flushing sodium from the body lower blood pressure?
the body regulates sodium level by adding water to blood in circulation, that contibutes to increasing blood pressure.
How do you correct blood sodium level?
sodium level in the body is controlled by a hormone called aldosterone which is made by adrenal glands small amount of sodium also loss by sweating.
What is an example of negative feedback?
An example of negative feedback would be a secretion of greater amount of insulin to lower the blood sugar level, and then secretion of greater amount of glucagon to increase the blood sugar level, and then a secretion of a greater amount of insulin to lower the blood sugar level..... etc.
What organ regulates blood sugar level in the body?
Insulin controls glucose levels in the blood. Those having diabetes or suppose to become diabetic, their insulin secretion is erratic and are to take insulin injection to stable the glucose level in the blood.
What are tips for lower blood pressure?
One of the best ways to lower your blood level is to reduce your sodium intake.Studies have shown that reducing the amount sodium in your diet can lower your blood pressure.
