When we breathe, we take in oxygen. I'm sure you know this. But the oxygen we take does not stop at the lungs. The air is taken in and filtered. Oxygen is given to red blood cells for processing, while Carbon Dioxide is released from our bodies.
So, why the Carbon Dioxide? Well, have you heard of bodily waste? Yes, that kind... Believe it or not, but carbon dioxide is a form of waste. Above, I stated that oxygen is processed. What I mean is that our body takes what they need from oxygen and dispose of the rest. The rest being Carbon Dioxide.
So, how does the air go from being oxygen to a compound molecule?
Oxygen is used for one purpose. In our bodies, we have what are called Mitocondria. Mitocondria need oxygen to accept electrons during Aerobic Respiration, routes by which energy is released.
Arteries and the pulmonary vein transport oxygen-rich blood through the body.
The lungs absorbs oxygen into the blood
The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
Arteries don't always carry blood that is high in oxygen. The term artery is an anatomical term. All blood vessels that carry blood away from the heart are arteries. All blood vessels that carry blood back to the heart are veins. Most arteries do carry blood that's high in oxygen but there is an exception. When the arteries carry blood to the lungs, this blood is low in oxygen. The veins that carry the blood back to the heart from the lungs is high in oxygen. This is called the pulmonary circuit. In this more or less seems backwards. It's best to remember that arteries carry blood away from the heart.
Fe, iron. This is the element that hemoglobin molecules carry through the blood. A deficit of iron in the blood is called anemia.
through your pulmonary artery and pulmonary vein.
By relaxing the blood vessels, antiangina drugs reduce the heart's work load and increase the amount of oxygenrich blood that reaches the heart.
Amfibians have two atria and one chamber so the oxygenrich and -poor blood is mixed. In mammals the heart is two-chambered so the blood wont mix.
The oxygenpoor ( carbon dioxide rich) blood from the right ventricle of heart is flow through the pulmonary artary to the lungs. And the gas exchange(exchange of carbon dioxide and oxyen ) takes place between the capillaries of pulmonary artary and the alveoli (air spaces) of the lungs .then the oxygenrich blood is collected by the pulmory veins to the left auricle of heart. pulmonary artary--- the only artary which carries deoxygenatad blood............. pumonary vein----------the only vein which carry oxygenated blood............
Arteries carry oxygenrich blood away from the heart, and veins carry oxygen depleted blood towards the heart. The aorta carries oxygen away from the heart to parts of the body. Hope this helps!
It is a result of thousands of years of evolution. But you also have to look at their functions. The left ventricle is pumping deoxygenated blood through the pulmonary artery to the lungs and back to the left part of the heart (including the left ventricle) which then pumps the oxygenrich blood out in the body. I guess you can imagine that pumping the blood in the body requires more work than pumping the blood to the lungs and back. I suggest you read more about the circulatory system and the heart if you have an exam or something that you have to prepare to. Best regards premed student
it is blood it is blood it is blood it is blood it is blood it is blood it is blood
oxygenated blood-blood that has oxygen2.deoxygenated blood-blood that does not have oxygen
I think upscale is a blood
blood types, Blood
now I do not know where you got that THERE IS NO SUCH THING ok? Sorry Good luck :)
Blood contains red blood cells. Red blood cells don't contain blood. Blood does not enter the red blood cell.
