Most of the oxygen exiting the blood and entering the tissues does so from the capillaries.
Answer: Option D
<u>Explanation:</u>
The circulatory system consists of the heart, arteries, veins and capillaries. An artery is the one which carry blood from the heart to the organs. A vein is the one which carry blood from the organ to the heart.
A capillary is the smallest blood vessel which helps connect the functions of arteries and veins in the body. The capillaries are the narrow tubes which allow diffusion of Oxygen into and from the tissues. It’s prior function is to drop Oxygen in a tissue and collect the Carbon dioxide from the tissue.
The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.
