Detailed explanation-1: -Oxygen gets into the blood through tiny blood vessels around the alveoli. Red blood cells pick up the oxygen and deliver it to the body’s cells.
Detailed explanation-2: -How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Detailed explanation-3: -Red blood cells help in transporting oxygen to all parts of the human body.
Detailed explanation-4: -The circulatory system, which is made up of the heart and blood vessels, supports the respiratory system by bringing blood to and from the lungs. The circulatory system helps deliver nutrients and oxygen from the lungs to tissues and organs throughout the body. It also helps remove carbon dioxide and waste products.
Detailed explanation-5: -Without blood, the body’s organs couldn’t get the oxygen and nutrients they need to survive, we couldn’t keep warm or cool off, fight infections, or get rid of our own waste products. Without enough blood, we’d weaken and die.
