What is the name for the widening of capillaries?
The widening of capillaries is known as "capillary dilation" or "capillary vasodilation." This process occurs when the smooth muscles in the walls of the capillaries relax, allowing for increased blood flow to a specific area, often in response to various physiological signals such as heat or inflammation. Capillary dilation plays a crucial role in thermoregulation and the delivery of nutrients to tissues.
What stimulates intestinal muscle contractions?
Nicotien or anything chemical which stimulates the Nicotinic receptors.
What stimulates vaso dilation?
Vasodilation is a mechanism for thermoregulation . It is used for cooling down body temperature . Increased body temperature stimulates vasodilation .It results in increased blood flow to skin to aid heat dissipation .
The intestinal villi contain capillaries and lacteals important chemical digestion?
Is it true that intestinal villi contains capillaries and lacteals important for chemical digestion?
What chemical stimulates muscle contraction?
acetylcholine (ACh)
What substances causes extreme dilation of arterioles and capllilares?
Substances like nitric oxide (NO), prostacyclin (PGI2), and adenosine can cause extreme dilation of arterioles and capillaries by promoting relaxation of smooth muscle cells in the blood vessel walls. This dilation increases blood flow to tissues and helps regulate blood pressure and tissue perfusion.
What is a foreign chemical that stimulates the production of antibodies?
An antigen is a foreign chemical that stimulates the production of antibodies by the immune system. Antigens can be bacteria, viruses, toxins, or other substances that are recognized as foreign by the body.
Why does the veins constrict and dilate during exercise?
