Answer: Vasodilation
Explanation:
vasodilation can be described as the process where the blood vessels widen within the body. Usually, it occurs when smooth muscles in the arteries and major veins relax and its major role is to distribute oxygen to different areas of the body, where it is needed most. It is a natural response of the blood vessels to low levels of oxygen or an increment in body temperature. There are certain health conditions related to vasodilation such as low blood pressure and inflammatory conditions.
Answer and Explanation:
Yes, a single molecule can work through all three effector route. Cells commonly lead independent lives, and they might influence and communicate with other cells for sexual mating. For example, yeast cells communicate with one another for mating. On the other hand, animal cells communicate by different kinds of signal molecules. These molecules include amino acids, nucleotides, proteins, small peptides, retinoid, and derivatives of fatty acids and also includes dissolved gases such as carbon monoxide and nitric oxide. In the extracellular spaces, most signal molecules are secreted by the signaling cells. Some signal molecules are exposed to the extracellular spaces, while others are released by diffusion. Target cells respond by a specific protein called receptors. Receptors bind the signal molecules and start response in the target cell. On the surface of target cells, receptors are transmembrane proteins. When receptors bind extracellular signal molecules, they stimulated and produced a flow of intracellular signals that initiate the cells' behavior.
Answer:
When a disease is acute, it will be a short duration. It may be severe and impair normal functioning. They also come on rapidly, and are accompanied by distinct symptoms that require urgent or short-term care, and get better once they are treated.
hope this helps :)
