Vasodilation, also known as vasorelaxation, is the widening of blood vessels. [1] It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins , large arteries , and smaller arterioles . [ 2 ]
Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are chlorine ions. Salt is involved in regulating the water content (fluid balance) of the body. Both sodium and chlorine ions are used for electrical signaling ...
Salt fulfills several important biological functions in humans. The human body has evolved to compensate for high salt intake through regulatory systems such as the renin angiotensin system . Salt is particularly involved with maintaining body fluid volume, including the regulation of osmotic balance in the blood, extracellular and ...
Vasodilators. These drugs, such as nitrates, are strong relaxing agents for the muscle in blood vessel walls. ... Eat plenty of vegetables, fruits, and whole grains, and limit your intake of salt ...
The short-term anti-hypertensive action is based on the fact that thiazides decrease preload, decreasing blood pressure. On the other hand, the long-term effect is due to an unknown vasodilator effect that decreases blood pressure by decreasing resistance. [4]
There are three volume regulating systems: two salt saving systems, the renin angiotensin aldosterone system and the renal sympathetic system (RSS); and the salt excreting natriuretic peptide (NP) hormone system. When the vascular space contracts, the RAAS and RSS are "turned on"; when the atria expand, NP's are "turned on".
