The autonomic nervous system is of two types: the sympathetic and the parasympathetic systems that is responsible for the mechanical and automatic functions in a human body.
<u>Explanation:</u>
The autonomic nervous system is of two types: the sympathetic and the parasympathetic systems that is responsible for the mechanical and automatic functions in a human body.
The parasympathetic nervous system is responsible for the digestion and relaxation of the body, it controls the homeostasis to keep the body in the right health, whereas the sympathetic nervous system helps in human body to react to things, to decide to whether to leave or fight the situation.
Parasympathetic nervous system helps the physical and mental system of the body to relax, whereas sympathetic nervous system erupts the conscious mind to be aware of the physical and mental motives.

Answer:
(A) - The volume of the blood plasma increases on overhydration and decreaes on dehydration.
(B) - Osmolality of blood increases with the dehydration and decreases with the overhydration.
Explanation:
If the levels of drinking water is increased, then the plasma becomes more dilute and the plasma volume increases because <u>the water will be reabsorbed more and which as a result reduces plasma concentration of the solutes and increases volume of plasma.</u>
Plasma osmolality measures electrolyte-water balance of the body. <u>As mentioned, above on overhydration, the plasma concentration of the solutes decraeses which also decreases osmolality. So, Osmolality of blood increases with the dehydration and decreases with the overhydration. </u>Increased osmolality in blood stimulate the secretion of antidiuretic hormone which results in the increased water reabsorption and therefore, more concentrated urine and hence blood plasma with less concentration.
Answer:
TRUE
Explanation:
In the cardiovascular system, the blood flows from <u>high pressure to low pressure.</u>
In the ventricular ejection phase, when the muscles of the ventricles contract, the<u> pressure gradient in ventricles rises</u>. This increases in the <u>pressure in the ventricles exceeds the pressure in the pulmonary artery </u>and aorta, thus opening pulmonary and aortic valves and ejecting the blood from the heart.
