James was walking down the road when a large animal jumped out in front of him. James was startled and experienced a fast heart
rate and heavy breathing. Which statement best describes James’s condition in such a situation? A.The adrenal gland secreted aldosterone, increasing sodium absorption, which increased the heart rate and breathing.
B.The adrenal gland secreted epinephrine, increasing blood pressure, which increased the heart rate and breathing.
C.The adrenal gland secreted androgens, stimulating calcium absorption, which increased the heart rate and breathing.
D.The adrenal gland secreted cortisol, increasing glucose absorption, which increased the heart rate and breathing.
As far as I know, the adrenal glands, when submitted under pressure such as the one described in the example, secrete a substance known as epinephrine which has the tendency of increasing the affected person's heart rate and breathing.
