What's the most reliable indicator you should use when determining if you should modify activity for heat?
sp2606 [1]

Heath index chart is the best indicator you should use when determining if you should modify activity for heat. The "heat index" is a single value that looks for both temperature and humidity. The higher the heat index, the weather will feel the hotter since sweat does not immediately evaporate and cool the skin. The heat index used is much better than air temperature alone for estimating the risk to workers from environmental heat sources.

Describe the neural and hormonal mechanisms that work to maintain blood pressure after significant (hemorrhaging) blood loss ass
Bad White [126]

Autoregulatory neural and endocrine mechanisms activate after blood loss to compensate for the loss and restore homeostasis.

Neural mechanisms involve blood pressure and blood chemistry. Cardiac centers and vasomotor centers may increase the blood flow and cardiac output (sympathetic) or decrease the blood flow and cardiac output (parasympathetic). Peripheral vessels are also constricted and nor epinephrine decreases flow in the arteries and decreases the flow in the veins.

Endocrine control acts in the renal and adrenal organs, the brain and heart. RBCs, renin/angiotensiogen/aldosterone, catecholamines, antidiretic hormone, atrial natriuretic hormone regulate blood volume and blood pressure by keeping the fluids in the cardiovascular system. It also initiates vasoconstrictors or vasodilators.
