Well animals do but plants don't. Plants don't actually really use oxygen- they give it out. They use the sunlight and Carbon Dioxide in photosynthesis and the by-product (what they give out) of this is Oxygen.
Plants don't have red blood cells. Red blood cells carry oxygen to the heart and lungs of animals, not plants. Plants take in CO2 and expel O2, so plants don't need red blood cells.
Animals need oxygen to carry out life processes. Plants need carbon dioxide. Some animals and plants can use either if they need to.
Plants produce oxygen, which animals use to breathe, from carbon dioxide, which the plants use to carry out their life processes.
plants, during photosynthesis,oxygen is release as by product which is used by animal to carry out respiration
Plants and animals release energy through cellular respiration. Plants and animals exchange gases through this process with animals taking in oxygen and plants carbon dioxide.
Systemic Arteries carry oxygen rich blood (also called oxygenated blood). Pulmonary Arteries carry oxygen poor (deoxygenated) blood
By definition, ALL arteries carry Oxygen rich blood. Veins carry oxygen depleted blood.
Veins carry oxygen depleted blood to the heart.
Usually veins carry blood low in oxygen back to the heart except for the pulmonary veins. They carry blood higher in oxygen.
red blood cels are the oxygenated cells..[ie carry oxygen]
no it carry's oxygen
Arteries carry Oxygen rich blood away from the heart. While our viens carry Oxygen poor blood back to get filed with more Oxygen
