Ques: Q: What type of blood does the right side of the heart collect and then pump to the lungs? Read this paragraph and choose the correct option from the provided answers: Blood flows through the heart in two separate loops, which are indicated by the arrows in Figure above. You can think of them as a "left side loop" and a "right side loop. " The right side of the heart collects oxygen-poor blood from the body and pumps the blood to the lungs.
