. One function of the circulatory system is to help maintain a uniform body temperature. Explain how the constant circulation of
Effectus [21]

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.

Can you write an essay about what makes a good rapper.<br> I will mark you Brainly.
DedPeter [7]

Answer:

There are many rappers out there in the world yet only a few of them are really well known and recognized. Of course this is because they meet peoples expectations. Different people have different opinions on what makes a good rapper. Things that I think make a good rapper is that they need to have good flow, meaningful lyrics that actually make sense and not just rhyme any word with another that doesn't make sense. Another thing is how they are like as a person as well. If they are a pretty decent human being and meets peoples expectations then they will be considered as a good rapper. If the person is not only ignorant but also can't rap well then they are considered bad. Like I said many people have different opinions but these are just mines.

Explanation:

You may change anything you would like but I hope this helped!
