No. It is absorbed through tiny pores on the surface of the leaf. These are called "stoma". The veins are for moving the tree's sap in the leaves for growth and nourishment.
Venous blood typically has a higher carbon dioxide content compared to arterial blood. This is because carbon dioxide is produced as a waste product of cellular metabolism and is carried back to the heart through veins to be expelled from the body through the lungs.
Blood flows from the venous system to the right atrium of the heart to the right ventricle of the heart through the pulmonary arteries, to the lungs (where the CO2/O2 exchange is done) through the pulmonary veins, and back to the left atrium of the heart, to the left ventricle of the heart, and out through the aorta and to the rest of the body. It then returns through the veins and repeats the process.
Coronary veins carry deoxygenated blood with carbon dioxide away from the heart muscle and back to the right atrium of the heart.
In a leaf, chloroplasts contain chlorophyll, which captures sunlight and initiates photosynthesis. The leaf's stomata allow carbon dioxide from the air to enter, while water absorbed by the roots travels to the leaf through veins. During photosynthesis, sunlight, carbon dioxide, and water are converted into glucose, providing energy for the plant, and oxygen is released as a byproduct. This process is essential for the plant's growth and survival.
Nothing does. Carbon monoxide is toxic. If your blood is rich in it, you will soon be dead. Veins generally carry blood that is rich in carbon dioxide.
Oxegen and Carbon dioxide
Yes, veins carry alot of carbon dioxide.
Yes. It is carried through the veins to the lungs to be exhaled.
The pulmonary veins are high in oxygen and low in carbon dioxide. All other veins are high in carbon dioxide and low in oxygen.
Blood containing carbon dioxide flows from veins throughout the body to the heart, and then the heart pumps it to the lungs. Small air sacs (alveoli) in the lungs remove the carbon dioxide from the blood and release it into the lungs where it is exhaled.
Veins carry blood low in oxygen back to the heart. However, the amount of oxygen in veins is still higher than the amount of carbon dioxide.
Blood cells carrying carbon dioxide return to the heart through veins, specifically the superior and inferior vena cava. These veins transport the deoxygenated blood back to the right side of the heart, which then pumps it to the lungs for oxygenation.
Arteries carry blood away from the heart and veins carry blood into the heart. Blood moving from the heart to the lungs through the pulmonary artery has less oxygen than blood moving from the lungs to the heart through the pulmonary vein, but most arteries carry oxygen-rich blood with little carbon dioxide, and most veins carry deoxygenated blood with carbon dioxide and other wastes.

Plants give us oxygen we give them carbon dioxide.
