The answer is <span>The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy.
When air enters the lungs (part of the respiratory system), it passes all way to the alveoli, the smallest functional units of the lung. There, oxygen from the air enters the capillaries, the smallest blood vessels, next to the alveoli. Once in the blood stream, the cardiovascular system transports oxygen to different cells where it is used for the energy production.</span>
Answer:
The correct answer will be Option-C.
Explanation:
The pancreas is an organ which plays an important role in the digestion of the food. Pancreatic juice is secreted by the pancreas which contains digestive enzymes as well as the sodium bicarbonate (base).
The sodium bicarbonate is required for the digestion of the food as after the acidic digestion of the food in the stomach, the food chyme enters small intestine. The inner lumpen is not structured to handle the acidic chyme so sodium bicarbonate neutralizes the acid chyme that entered the lumen of the small intestine.
Thus, Option-C is the correct answer.
