The calories in one teaspoon of sugar can vary slightly depending on the manufacture of the spoon, but also on how much you scoop up. Using a measuring spoon would be a good way to get the exact quantity of sugar a teaspoon actually has, which is particularly useful when you are baking.
Blood becomes oxygenated through the process of diffusion in the lungs, more specifically referred to as gas exchange. It is a passive process so that means that many capillaries need to be in close contact with the air that we inspire. In fact the most intimate contact we have with the external world is in our lungs.he veins lead the de-oxygenated blood back to the heart, where  it goes through the right atrium, right ventricle, and through the  Pulmonary Arteries to the lungs, where g â¦ as exchange happens.
Arteries carry blood away from the heart. Usually this means they are carrying oxygenated blood to the body. The pulmonary arteries carry de-oxygenated blood to the lungs where it becomes oxygenated, is taken back to the heart in the pulmonary veins and then is pumped to the rest of the body. snapdragon Â· 7 years ago.m not 100% sure, but i believe this to be true. Arteries carry oxygenated blood. This is because they carry blood away from the heart and around the body, without the blood being oxygenated, it isnt doing its job correctly, which is to get oxygen to, for example, the muscles.
