Question

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?
The adrenal gland secreted aldosterone, increasing sodium absorption, which increased the heart rate and breathing.


The adrenal gland secreted epinephrine, increasing blood pressure, which increased the heart rate and breathing.


The adrenal gland secreted androgens, stimulating calcium absorption, which increased the heart rate and breathing.


The adrenal gland secreted cortisol, increasing glucose absorption, which increased the heart rate and breathing.

Answer 1

Answer:

Option (2).

Explanation:

Epinephrine is also known as adrenaline. This hormone is released by the adrenal gland in the fight and flight conditions. The sympathetic nervous system of the brain maintains the fight and flight conditions of the body.

James body is in fight and flight condition when he saw that large animals jump in front of him. This condition causes the release of epinephrine hormone. The release of epinephrine in blood increases the blood pressure of the body. The heart rate and breathing also increases in this condition.

Thus, the correct answer is option (2).

Answer 2

The answer is most likely the second one. It makes the most sense.

Hope this helps!
