The eye works like a lens. Every lens has a focus point. If it's a converging lens, it converges light onto the focus point. If you put a screen at that point, the image formed will be as clear as it could get. If you move the screen a bit closer or farther it will gradually blurr. Same with moving the light source. In fact, when an image is blurry, that &;single point&is spread across the z direction. However, in the case of the human eye, the light source is the observed object therefor the retina is the screen itself. When a person with myopia looks at a far object, the focus point is off the retina so the image is blurry. However, when that person looks at a near object, the light source has become closer, so the focus point is closer to the retina and the image looks clear, but keep in mind, the image is not 100% clear because the focus point is not located exactly on the retina.

Exchange of gases between alveoli and the bloodstream ( Option C )
Internal respiration is the process of exchanging gases ( i.e. carbon dioxide and oxygen ) between the bloodstream and the alveoli of an organism. as seen in human.
- Internal respiration ( exchange of gases) occurs between Alveoli and the bloodstream. While
- External respiration occurs between the atmosphere and the alveoli.
Also the Alveoli is important in both external and internal respiration. but for internal respiration, the alveoli exchanges gases with the bloodstream before it is passed to the internal issues .
Hence we can conclude that the true statement about internal respiration is ; Exchange of gases between the alveoli and the bloodstream.
