What is the Oxygenated and Deoxygenated Blood

Q. What is the difference between oxygenated and deoxygenated blood? 

The blood treated with oxygen in the lungs is known as oxygenated blood. It’s also referred to as arterial blood. Blood goes to the lungs, where haemoglobin in red blood cells absorbs atmospheric oxygen. It travels from the lungs to the heart’s left chamber via the pulmonary vein. 

The oxygenated blood is brilliant red because the bulk of haemoglobins in this blood was connected to oxygen. It has a purple tint that shows through into the skin. The partial pressure of oxygen in oxygenated blood is around 100 millimetres of mercury. Oxygenated blood is high in oxygen and other nutrients, including glucose, amino acids, and vitamins. It transports oxygen and nutrients to the cells from the heart toward the metabolising tissues throughout the body. The systemic arteries within the body carry oxygenated blood. 

Especially contrasted to blood exiting the lungs, deoxygenated blood is blood which has a low oxygen saturation. It was also called venous blood. The body absorbs oxygen through oxygenated blood and then expels carbon dioxide as a waste substance. 

As a result, the blood which leaves these tissues has a low partial pressure of oxygen and a high partial pressure of carbon dioxide. This blood is transported to the heart’s right atrium via a systemic vein. The pulmonary veins transport blood from the right ventricle to the lungs. As opposed to oxygenated blood, deoxygenated blood contains fewer minerals. In contrast, it is high in metabolic byproducts like urea and carbon dioxide.
