Question

Name the hormone that regulates the heartbeat and blood pressure.

Answer 1

Hint:-Hormones are released by endocrine glands into the bloodstream. In other parts of the body, this allows the hormones to travel to cells. Endocrine hormones help regulate mood, growth and growth, the way our organs function, metabolism , and reproduction. How much of each hormone is released is regulated by the endocrine system. This may depend on the level of hormones already in the blood or on the level of other substances, such as calcium, in the blood. Hormone levels, such as stress, infection, and changes in the balance of blood fluid and minerals, are affected by many things.

Complete Answer:-The kidneys renin-angiotensin - aldosterone system regulates the volume of blood. The juxtaglomerular cells in the kidneys secrete renin into the blood as a response to rising blood pressure. Renin converts the plasma protein angiotensinogen to angiotensin I, which is then converted by lung enzymes to angiotensin II.
Angiotensin II constricts blood vessels (increasing blood pressure by increasing blood flow resistance) throughout the body. The amount of blood delivered to the kidneys, which reduces the potential of the kidneys to excrete water (increasing blood pressure by increasing blood volume), is reduced by constricted blood vessels.
Angiotensin II stimulates the adrenal cortex to secrete aldosterone, a hormone that by increasing water retention and sodium by the kidneys (increasing blood pressure by increasing blood volume) decreases urine output.
Epinephrine and norepinephrine, adrenal medulla-secreted hormones, increase blood pressure by increasing heart rate and heart muscle contractility and by causing artery and vein vasoconstriction. As part of the fight-or - flight response, these hormones are secreted.
By stimulating the kidneys to retain water, antidiuretic hormone (ADH), a hormone produced by the hypothalamus and released by the posterior pituitary, raises blood pressure (increasing blood pressure by increasing blood volume). The heart rate and force of contraction are increased by thyroid hormones.

Note:- To help maintain the health of your endocrine system:
1. Get plenty of exercise.
2. Eat a diet that is nutritious.
3. Go for routine medical checkups.
4. Before taking any supplements or herbal treatments, talk to the doctor.
