ANSWER 1 : Renal and respiratory systems directly involve in the process of excretion of metabolic wastes since respiratory organ( lungs) and kidney ( renal organ) excrete CO2 and nitrogenous wastes respectively as main metabolic waste product.
ANSWER 2: The Hormone nor-epinephrine acting directly via beta-2 receptors binding with sympathetic post ganglions of lungs for activation of bronchioles, it dilate the bronhioles for more blood supply.
ANSWER 3: The vagus nerve (tenth cranial nerve) involves in doing diverse functions in several organ system of body. It slowing down the functions such as blood pressure, heart rate, vasodilation via parasympathetic autonomic system and increase the vital function as increase blood pressure by vasoconstriction. The gastric secretion (HCL) and pancreatic secretions and control of diameter of bronchiole due to pneumogastric property of this nerve.
ANSWER 4: All the given type of constrictions except enterogastric reflex smooth muscles involve predominantly because enterogastric reflex affect mainly enterogastric functions such as HCL secretion and other local secretions.
ANSWER 5: For all of the given functions of carbonic anhydrase, oxygen transportation is least suitable option for it because oxygen transport is mainly done by haemoglobin a complex chromoprotein as oxy-haemoglobin complex, so carbonic anhydrase is obiously not involved.
