A. Epinephrine-( iv). Increases heart beat

Epinephrine during stress or emergency condition increases blood flow to the heart, liver, muscles etc which increases systolic blood pressure thus heart beat increases.

B. Testosterone-( i). Stimulates muscle growth

Testosterone is a male gonadal hormone. It stimulates muscular growth, facial hair etc. It has a protein called anabolic which promotes bone growth and that’s why more muscular physique in males.

C. Glucagon –(iii). Breakdown of liver glycogen content

Glucagon is a hormone secreted by pancreas which acts on hepatocytes to induce glycogenolysis and gluconeogenesis. It breakdown liver glycogen content to raise blood glucose level.

D. Atrialnatriuretic factor- (ii). Decrease in blood pressure

When blood flow increases to the atria of heart than it causes the release of Atrialnatriuretic factor. This factor causes vasodilationand thus decreases the blood pressure.
