capillaries
The capillary is known as the functional unit of the cardiovascular system. Capillaries are small blood vessels where gas exchange and nutrient exchange occur between the blood and tissues. This exchange is essential for delivering oxygen and nutrients to cells and removing waste products.
Gas exchange occurs in the alveoli of the lungs. These tiny air sacs are surrounded by capillaries where oxygen from the air can enter the bloodstream and carbon dioxide can be removed from the blood.
Lenticells are small, spongy openings on the surface of stems and roots of plants that allow for gas exchange, particularly oxygen, to occur. They help facilitate the movement of gases in and out of the plant's internal tissues, aiding in respiration and nutrient transport.
The chorion develops into the fetal portion of the placenta. It plays a crucial role in nutrient and gas exchange between the mother and the fetus during pregnancy.
The air space keeps the stomata moist so that transpiration and gas exchange can occur. The gas exchange in the stomata needs to take place so that photosynthesis can occur. So without the air space you have no stomata, and without the stomata you have no photosynthesis which is how plants obtain their food.
The capillaries are responsible for gas and nutrient exchange with each of the body's cells. These tiny blood vessels have thin walls that allow for the exchange of oxygen, carbon dioxide, and nutrients between the blood and the surrounding tissues.
The gas occurs by simple diffusion through the cells.

Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
