Full Answer

For Dummies says that deoxygenated blood enters the right atrium of the heart during circulation, at which point it is forced through the pulmonary valve and into the pulmonary artery. Here, the deoxygenated blood travels through the pulmonary artery to the lungs where it receives oxygen and becomes oxygenated blood again. From here, the process starts all over again, and the oxygenated blood leaves the pulmonary artery to bring oxygen to the cell membranes once more.

  • Q:

    Why is blood red?

    A:

    The red color of blood comes from the hemoglobin that makes up the majority of the mass of the cell, which allows the blood cell to carry oxygen around the body. The plasma itself is a straw color when viewed under a microscope, but the hemoglobin makes up so much of the blood cell that its red color overpowers the color of the plasma. When a red blood cell is full of oxygen, the red has a scarlet tint to it, when it has released it's oxygen its more of a dark burgundy color.

    What are the differences between oxygenated and deoxygenated blood?

    A:

    Oxygenated blood is filled with oxygen from the lungs. In contrast, deoxygenated blood has had most of its oxygen removed and is returning to the lungs, ready to become reoxygenated.

  • Q:

    What happens when blood reaches the lungs?

    A:

    Blood that reaches the lungs travels throughout a network of small blood vessels, where oxygen moves into the blood and carbon dioxide moves out of the blood, according to the National Heart, Lung and Blood Institute. This oxygen-rich blood is transported through the pulmonary veins and back to the heart, where it is pumped out to the rest of the body.
