Explain why elderly individuals with poor circulation would have a greater risk of suffering heat exhaustion or heatstrok.

Answer and explanation:

Blood circulation is very important for the maintaining of homeostasis, which is the state in which the body functions properly and is achieved by finely regulating several variables such as pH, osmotic balance, and body temperature.

Blood circulation specifically is fundamental for the regulation of body temperature because, for example, when the body temperature is higher than it should, the blood vessels in the skin dilate (vasodilatation) so blood can flow faster and be lost to the air, causing the body temperature to drop.

Elderly people with poor circulation have a greater risk of heat exhaustion because their blood vessels may not dilate as well as they should, which will eventually make their bodies too hot.
