Answer:
Capillaries are the blood vessels with the smallest diameter and those closest to the surface of the skin. The blood that circulates through them is therefore closer to the outside air than the blood in the rest of our blood vessels. As the capillary dilates, a greater amount of blood is exposed to the air, which allows it to cool down and our body temperature to be maintained.
Explanation:
Blood is a solution where solutes and cells are found and that participates in homeostatic mechanisms such as the control of body temperature, helping to regulate respectively the preservation and elimination of heat. Blood vessels are the routes of the cardiovascular system, which are responsible for being a means of transport for blood with and without oxygen that reaches all tissues and returns to the heart. In very hot weather, surface thermoreceptors signal the brain that something needs to be done to dissipate heat. For this reason, a vasodilation process is activated, which allows blood to flow to the outermost layers of the skin. This promotes a heat exchange with the environment, which helps the individual to lower their body temperature. Cold causes a decrease in blood flow by reducing the size of the vessel (arteries or veins) through which blood and other substances circulate. By reducing the size of the vessel, the substances that circulate in the blood are also reduced. The heat causes an increase in the size of the blood vessels, which generates greater transport of nutrients through the blood.
Hellbenders are fully aquatic, which means they cannot live out of water and do not try to crawl out of their stream or river habitat. As river water flows over their body, oxygen is taken up by tiny blood vessels in the skin and carbon dioxide is released

<span>I think you might be asking about the 3 different osmotic conditions a cell might find itself in. Isotonic is the normal cell environment where water moves in and out of the cell freely and equally in both directions. It is in osmotic equilibrium so to speak. The concentration of water and solutes is equal on both sides of the cello membrane. In a hypotonic solution the cell will gain water and swell up -...</span>
