Answer both in 1 thread ASAP. Thanking you in advance.

Dear student,
Adrenaline hormone is secreted by the adrenal glands located on the kidneys' top in response to stress, emergency, or threat. The hormone causes the following changes in the body-

• During an emergency or stress, the body requires more oxygen to form energy to combat. Thus, the hormone increases the heartbeat to supply the required oxygen.
• The hormone also contracts the diaphragm to increase the breathing rate.
• Adrenaline also helps in the contraction of muscles around arteries.
• The blood flow to the digestive system is reduced because of muscle contraction.

Therefore, the correct option is D for the question given on the left.

• During an emergency or stress, the body requires more oxygen to form energy to combat. Thus, the hormone increases the heartbeat and the breathing rate to supply the required oxygen.

Therefore, the correct option is B for the question given on the right.
