When areas of skin are completely deprived of any blood flow, and therefore of any oxygen delivery, the skin may die and turn black
Your skin gets wet and salty
When the temperature decreases, blood flow to the skin typically decreases as well. This process, known as vasoconstriction, occurs to conserve body heat by reducing the amount of warm blood reaching the skin's surface. As a result, the skin may appear paler, and the body prioritizes blood flow to vital organs to maintain core temperature.
Your blood vessels move closer to your bone therefore further from skin so it looks less red. This happens so your blood in your blood vessels is warmer so your extremities don't cool it down as much and cool your body down.
No, the perforating canal does not supply blood to the skin. It is a passageway for blood vessels and nerves to enter the bone from the periosteum. Blood supply to the skin is mainly through dermal arteries and capillaries located in the dermis layer of the skin.
A skin hematoma is a bruise caused by damaged blood vessels leaking blood into the surrounding tissue. It typically appears as a red/purple area on the skin due to the blood accumulation underneath the surface. Hematomas usually resolve on their own as the body reabsorbs the blood.
actually what happens to you is your skin gets so pruned and wrinkly that your blood has clots and gets tightened and thick so you die of starvation and blood conflicts.
When skin gets cold, blood vessels constrict to conserve heat and reduce blood flow to the skin's surface. This can lead to a pale appearance and make the skin feel cold to the touch. Prolonged exposure to cold temperatures can also cause skin damage, such as frostbite.
it gets wrinklely
Your skin gets wet and salty
It gets thicker
Nothing - peoples skin is water (and blood) proof.
You will not have any fleas.
you get goosebumps.
they die
it gets pumped away from the heart
Nervous impulses sent to muscles generate extra metabolic heat through shivering. Otherwise, your blood vessels transport warm blood from the internal organs to our , cold, skin, then your blood will lose heat.
It does nothing other than existing.
