The hypothalamic part of brain helps modulate thirst in the body. It is considered to be the link between the nervous system and the endocrine system of the body. When the body needs water, the hypothalamus increases the synthesis of an anti-diuretic hormone called vasopressin, which is mainly secreted from the pituitary gland.

Where is interstitial water found?
Fluid found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them. As new interstitial fluid is made, it replaces older fluid, which drains towards lymph vessels.
What fraction of fat tissue represents the water content?
Adipose tissue contains about 10% of water, while muscle tissue contains about 75%.
What is the function of renin quizlet?
What is the function of Renin? Cells in the kidneys respond to low blood pressure by releasing an enzyme called renin. Renin causes the kidneys to reabsorb sodium. Sodium reabsorption, in turn, is always accompanied by water retention.
Which of the following regulates the level of calcium in the blood?
Parathyroid gland regulates calcium levels in the body. It produces a hormone called parathyroid hormone (PTH).
What organ provides the major control for homeostasis of body fluids?
The kidneys are the main osmoregulatory organs in mammalian systems; they function to filter blood and maintain the dissolved ion concentrations of body fluids.
Which type of tissue of the body contains the most water content?
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
What is renin in the body?
Renin is a protein (enzyme) released by special kidney cells when you have a decreased salt (sodium) level or low blood volume. Most often, the renin blood test is done at the same time as an aldosterone blood test to calculate the renin to aldosterone ratio.
How does renin angiotensin system regulate blood pressure quizlet?
When blood pressure falls (for systolic, to 100 mm Hg or lower), the kidneys release the enzyme renin into the bloodstream. Renin splits angiotensinogen, a large protein secreted from the liver that circulates in the bloodstream into pieces.
What is the primary function of renin?
Renin is an enzyme that helps control your blood pressure and maintain healthy levels of sodium and potassium in your body. Made by special cells in your kidneys, renin is released into your bloodstream when your blood pressure drops too low.
Where is the parathyroid?
The parathyroid glands lie behind the thyroid. They produce parathyroid hormone, which plays a role in regulating the body's blood level of calcium and phosphorus. Hyperparathyroidism is when your parathyroid glands create high amounts of parathyroid hormone in the bloodstream.
What is calcium's role in the body?
Calcium is a mineral most often associated with healthy bones and teeth, although it also plays an important role in blood clotting, helping muscles to contract, and regulating normal heart rhythms and nerve functions.
What is the function of parathormone?
Parathyroid hormone (PTH) is a hormone your parathyroid glands release to control calcium levels in your blood. It also controls phosphorus and vitamin D levels. If your body has too much or too little parathyroid hormone, it can cause symptoms related to abnormal blood calcium levels.
