Answer: Red blood cells carry oxygen to the rest of the body. Red bloodcells are also called erythrocytes, or abbreviated RBC. Each redblood cell (RBC) contains a protein called hemoglobin. Eachhemoglobin molecule can bind up to four oxygen molecules to it. These are the red blood cells, also known as erythrocytes. They areone of the very few cell types in the human which do not contain anucleus (in healthy individuals). 95% of their protein content ishaemoglobin, the protein which is responsible for binding oxygen. red blood cells llamas Edited answer: Red Blood Cells (RBC) red blood cell
Answer: oxygen (O2) enters the body via respiration (breathing) it enters small pouches in the lungs called alveoli. these alveoli are surrounded by tiny blood vessels called capillaries. there is an exchange at these alveoli, carbon dioxide (CO2) exits the blood and O2 enters the blood. this freshly oxygenated blood is now returned via the pulmonary vein to the Left side of the heart. the left ventricle pumps blood to the body. as the blood vessels get smaller they again form capillaries. there is another exchange of gasses, O2 is transferred out to the cells and CO2 (the waste product from cellular metabolism) is transferred to the blood. the Deoxygenated blood is then returned via the venous system to the right side of the heart. the deoxygenated blood is pumped back to the lungs and the alveoli via the pulmonary artery. and then the whole cycle starts over again.
Answer: Oxygen attaches to the haemoglobin in your red blood cells. Your red blood cells circulate around your body via arteries and capillaries supplying blood to all of your body cells. Then, veins take the deoxygenated blood back to the heart and from there the pulmonary artery takes it to the lungs for it to become oxygenated once again. The pulmonary vein then takes the blood to the heart once again, and the process repeats itself.
Answer: The lungs take in air. then lung capillaries, or small blood vessels, carry the blood to exchange carbon dioxide and oxygen. Then the heart pumps the oxygenated blood to the cells that need oxygen to break down sugar molecules.
