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.
Not always. The pulmonary artery and the pulmonary vein reverse the general roles of O2 rich and poor blood. The pulmonary artery carries O2 poor blood to the lungs and the pulmonary vein carries O2 rich blood back to the heart in order to be sent to the rest of the body.
Carbon Monoxide: is a colorless, odorless, tastless gas that when inhaled is toxic to humans. Carbon Monoxide: is a byproduct of a rich mixture fire, Burning wood, Gas fires, etc. Your answer is No! Trees use Carbon Dioxide which is what you release when you exhale. So-Live long.
Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
The renal vein is low in oxygen because it carries blood that has already been filtered by the kidneys. As the blood flows through the kidneys, waste products are removed and nutrients are reabsorbed, which depletes the oxygen content of the blood.
When air is inspired, it goes into the lungs, spreads across the alveoli which are like air sacs, and increases the oxygen content in the blood (through capillaries) with the help of hemoglobin. At the same time, carbon dioxide is being transferred into the alveoli by the capillaries used to transfer blood. The oxygen rich blood is sent through the pulmonary vein into the right side of the heart where it is transferred to the rest of the body. Meanwhile, the carbon dioxide that had been collected by the air sacs in the lungs is expired.
Dorsal aorta carries oxygenated blood from the lungs to the tissues, while the ventral aorta carries impure blood (rich in carbon dioxide) from the heart to the lungs.
Carbon dioxide rich blood, which is red blood cells lacking oxygen but high in carbon dioxide concentration.These blood cells have circulated through the body and given up much of its oxygen while collecting waste carbon dioxide. The pulmonary artery carries this blood from the heart to the lungs, where it picks up a fresh supply of oxygen and eliminates carbon dioxide.
carbon monoxide is a rich indicator, if you are producing too much, you have a fuel system problem.
Carboxyhaemoglobin (carbon dioxide rich blood) is a red-purple colour.Oxyhaemoglobin (Oxygen rich blood ) is deep redCarbonmonoxyhaemoglobin (Blood containing carbon monoxide) is bright redAside: Some people think some blood is blue because veins (containing CO2 rich blood) appear blue. This is due to the colour of the veins and the colur absorption of the tissues. Octopi and horseshoe crabs do have blue blood because they use copper, not iron, to transport oxygen.
Blood comes into the heart from the systemic circuit. It is low in oxygen. It comes by way of the inferior and superior vena.
There are many tiny blood vessels in the lungs called capillaries and these have thin membranes through which oxygen can flow from the lungs into the blood. They also exchange carbon dioxide which you exhale. The heart carries carbon dioxide rich blood to the lungs where it is expelled and oxygen is absorbed into the blood when you inhale and that oxygen rich blood goes back to the heart along a different artery than the one carrying the carbon dioxide rich blood.
In the leopard frog heart, the right atrium carries oxygen poor blood and the left atrium carries oxygen rich blood.
The pulmonary veins carry O2 rich blood to the heart.
Blood carries oxygen and nutrients to the organs.
Oxygenated blood or oxygen rich blood.
In short, the veinules, the pulmonary artery, and all veins except for the pulmonary vein are the blood vessels that carry blood that is rich in carbon dioxide. Unless you want to explain all that, the best answer is "veins." The capillaries that carry carbon dioxide back toward the heart are called veinules. The veinules join up to form veins. They eventually connect to the vena cava. The vena cava, which is the largest vein coming from the body, also carries deoxygenated blood, like nearly every other vein. The pulmonary artery carries deoxygenated blood from the heart to the lungs and is the only artery in the body that carries deoxygenated blood. The pulmonary vein carries oxygenated blood from the lungs to the heart, and it is the only vein that carries oxygen-rich blood.
The pulmonary artery carries deoxygenated blood from the heart to the lungs.
