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.
<span>The pancreas secretes digestive enzymes in the slender instincts, these enzymes produce endocrine secretions through the hormones and pass through the blood. Endocrine cells called pancreatic islets secrete insulin and glucagon and have endocrine functions that are formed through the hormones and pass through the bloodstream.</span>
Answer;
-DNA
Explanation;
-DNA stands for deoxyribonucleic acid. It's the genetic code that determines all the characteristics of a living thing.
-It contains the genetic instructions for the development and function of living things. These instructions are needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the activities in our bodies.
