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.
Answer:
Obese
Explanation:
Obesity can occur at any age but in recent times more and more children are becoming obese. They develop an unhealthy relationship with food from a young age. Food rather than being a source of nutrition becomes just a source of sensory stimulation.
These children often chew very fast and swallow food without properly breaking it down. Thus they are not able to realize when they are full. They ignore the internal cues for hunger or fullness and keep eating to satisfy their palate. As a result, they become obese.
Answer:
One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.
Explanation:
It seems that you have missed the necessary options to answer this question, but anyway here is the answer. Since the person spends several days in a hot, dry desert environment with little water available to drink, the kidneys' function during this time is that, the amount of urine produced is decreased in order to maintain the proper amount of water in the bloodstream. Hope this answer helps.
