The body uses folate to produce heme, a component of hemoglobin that helps carry oxygen. Red blood cells will not be able to mature if a person does not get enough folate. This may lead to folate-deficiency anemia and low hemoglobin levels. Good sources of folate include: spinach beans, ...
Our ability to breathe oxygen is critical to our survival. This process is mediated by the hemoglobin in our blood, which carries oxygen. Since air contains less oxygen on high mountains, the body is under pressure to make hemoglobin rapidly—a stressful time. But what role does cellular stres...
An RBC contains hemoglobin, a molecule specially designed to hold oxygen and carry it to cells that need it. The primary function of red blood cells is to transport oxygen from the lungs to the cells of the body. RBCs contain a protein called hemoglobin that actually carries the oxygen. In...
Unlike human blood, a roach's blood doesn't use hemoglobin to carry oxygen, so it is colorless instead of red. The blood also doesn't travel through an extensive circulatory system. Although an aorta carries blood to specific organs, much of the blood travels through a network of spaces ...
