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.

Explanation:
Yes, it is possible to develop effective vaccines for any type of viruses. Genetically engineered viruses exhibit similar characteristics to natural viruses.
<h3>What is a virus?</h3>
A virus is a genetically independent entity that needs a suitable host to reproduce its genetic material (either DNA or RNA).
A genetically engineered virus is a virus whose genetic material has been modified using genetic engineering techniques.
Vaccines can be developed for removing any type of viruses because they take advantage of the intrinsic properties of the immune system (i.e., antigen recognition), independently of its origin.
