The nose.
food making and plants breathe carbon dioxide
Carbon dioxide and oxygen enter and leave the plant through the stomata, on the underside of leaves.
Leaves are a part of a plant. Plants TAKE IN carbon dioxide and GIVE OFF oxygen.THEREFORE, leaves do not give oxygen. :D Leaves are however key part of the photosynthesis process.
Blood flows in a circle from lungs to tissues and back. At the lungs O2 gets into the blood and CO2 gets out - at the tissues O2 leaves the blood and CO2 enters.
The nose.
oxygen enters and glucose is released... follow on instagram @nailsbyisis
it is wher the oxygen and carbon dioxide both enters and exit.:)
Oxygen is entered through the mouth and carbon dioxide is released out of the mouth.
The air that enters the lungs is richer in oxygen when it enters the lungs. when it leaves it has more carbon dioxide and less oxygen as the lungs expel carbon dioxde and some unused oxygen.
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
Alveoli.
Carbon Dioxide enters the plant through small openings on the undersides of the leaves called stomata.
The oxygen cells Actually the carbon dioxide is removed. Oxygen is taken in by the blood and circulated to the rest of the body.
Alveoli (plural) and alveolus (singular)
Carbon dioxide and oxygen enter via the stomata which are tiny pores in the leaves and other organs of plants. Please see the link.
Oxygen (O2) enters the blood through inhalation and is circulated throughout the body. Carbon Dioxide (CO2) is filtered out of the blood as a waste product and exhaled.
