How does the circlutory system keep you cool?

When your body temperature is high, yourperipheral blood vessels dialate. This causes them to be closer to the surface of the body - thus releasing heat. When the body is too cold they constrict, keeping all of the heat in.


How does the sympathetic nervous system contribute to an increase in blood pressure?

The sympathetic nervous system increases blood pressure by releasing adrenaline, which causes blood vessels to constrict and the heart to beat faster and stronger. This response helps the body prepare for fight or flight situations.


How does sympathetic activation affect blood vessel diameter, leading to either vasodilation or vasoconstriction?

Sympathetic activation can cause blood vessels to either dilate (vasodilation) or constrict (vasoconstriction) by releasing neurotransmitters that bind to receptors on the blood vessel walls. When the sympathetic nervous system is activated, it releases norepinephrine, which can bind to alpha-adrenergic receptors on blood vessels, causing them to constrict and decrease blood flow. Alternatively, the release of epinephrine can bind to beta-adrenergic receptors, leading to vasodilation and an increase in blood flow.


How does sympathetic activation affect the constriction of blood vessels?

Sympathetic activation causes blood vessels to constrict by releasing a neurotransmitter called norepinephrine, which binds to receptors on the smooth muscle cells of the blood vessels. This binding triggers a series of events that ultimately lead to the contraction of the smooth muscle, resulting in the narrowing of the blood vessels.

Why does ascending saturated air cool more slowly than ascending unsaturated air?

Saturated air contains relaitvely higher amount of water molecules. Thus it requires much time to cool. Whereas in case of unsaturated air, the number of water molecules are less. So, it's much obvious that lesser amount of water molecules require less time to cool.
