Oxygen and carbon dioxide travel into and out of the bloodstream via diffusion across alveolar and capillary membranes.
stoma (pural) stomata
Capillaries. The diffusion of nutrients, oxygen, carbon dioxide and wastes take place in the capillaries. If you want to be more specific, it would be the venous ends of the capillaries where carbon dioxide enters the blood.
Carbon Dioxide
siol
Both carbon dioxide and oxygen found in air enters through the stomata. More at Link
Carbon Dioxide enters the plant through small openings on the undersides of the leaves called stomata.
osmosis
in enters through something called stomata
Carbon enters a consumer contained in the complex molecules of the food the consumer eats. Carbon exits the consumer as a gas called Carbon Dioxide - which is usually breathed out.

Mainly Carbon dioxide enters. Some water can enter,but majority of water leaves through them

We find that carbon dioxide is removed from the body via what is called gas exchange in the lungs. When we inhale, air is drawn into the lungs, and the alveoli in the lungs are the sites where gas exchange takes place. Carbon dioxide exits the blood, and oxygen enters. When we exhale, the carbon dioxide is carried out of the body, and the process is repeated with another breath.
