In hot weather - blood vessels dilate (widen) - to allow the exchange of heat between the blood and sweat glands. The sweat evaporates - cooling the blood.
In the "hot zone," Monet's tissues and blood vessels would likely be experiencing severe damage due to the high temperatures. The tissues may be undergoing heat-induced changes, such as denaturation of proteins and cell death. Blood vessels could be dilated and inflamed in response to the heat stress.
Capillaries are the smallest blood vessels.
Blood vessels are elastic in order to maintain the circulatory system. The vessels need to be able to stretch based on the force of the blood that is pumped through them. There are also receptors on blood vessels that control the diameter in order to shift blood to other parts of the body.
larger blood vessels called veins which carry the blood back to the heart
within blood vessels
During warmer weather, the blood vessels at the surface of the skin dilate. At the same time, our skin produces sweat, which evaporates - taking the excess heat into the atmosphere.
When the weather is hot, blood vessels in the skin dilate, a process known as vasodilation. This allows for increased blood flow to the skin's surface, facilitating heat dissipation through radiation and convection. As a result, the body cools down more effectively, helping to regulate internal temperature. Additionally, this process can cause the skin to appear flushed or reddened.

Due to dry climate or environment,your nasal membranes dry out and crack which results to bleeding. Ok there you go. I hope I answered your question.
The blood vessels near the skin enlarge so that the hot blood is nearer the surface of the skin to transfer heat away from the body.
Yes, fingers can swell in cold weather due to reduced blood flow and constriction of blood vessels.
Another name for vein is blood vessel.
When you get hot, your blood flow increases and your blood vessels also get closer to the surface of your skin to allow the air to help you cool down. That is why your skin appears pink; your blood is closer to the surface.
Blood vessels dialate (open more) and the heart rate increases to dissipate body heat. In cold temps such as hypothermia, the blood vessels constrict and the heart rate lowers. Extremehypothermia or hyperthermia are both life-threatening.
In hot weather the brain causers the vessels to move close to the surface and dilate. In cold weather it causes the vessels to move away from the surface and contract.
Blood Vessels-are the passageway of blood.
