Eli has taken large amount of acidic lemon juice which has increased the blood acidity. As a result, the body reduces the respiration rate to compensate the acidity with decrease exhalation of CO₂. Hence, he is given intravenous solution of bicarbonate to neutralize the blood acidity.
Explanation:
Eli is observing symptoms of difficulty in breathing because his RR is decreased by the autonomic nervous system which is dedicated to maintain normal pH and body hemeostasis. The Respiration center decrease respiration so that less CO₂ is exhaled and greater amount of CO₂ is present in the body to neutralize lemon acid. Hence, Eli is given bicarbonate solution intravenously to make the bicarbonate available in blood stream immediately and lower the acidity of blood.

The heart is the primary organ, which pumps blood through the body. The heart automatically adjusts the blood flow to match the activity levels by the intake of more oxygen.
The heart functions appropriately in the presence of oxygen. During a time of activity or an exercise, the body requires an extra amount of energy to meet the needs of the activity. The heart adjusts itself by taking up more oxygen so that the blood flow is increased and the oxygen demand is met.
The heart pumps necessary blood volume to different parts of the body such that, the body does not suffer from any physiological problems.
Thus, the heart sets the blood flow by taking up more oxygen. The correct answer is Option B.
