Answer: blood. blood has plasma, platelets,white blood cells and red blood cells.plasma carries waste materials . platelets covers wounds white blood cells helps in fighting germs and red blood cells carry blood with oxyhaemoglobin
Answer: Oxygen rich blood is physically transported by arteries; which lead away from the heart. Oxygen depleted blood is transported back to the heart by veins. Arteries are bigger than veins and are set deeper within the body.Within the veins and arteries are red blood cells that technically "carry" the oxygen.Red blood cells are composed of the protein haemoglobin which is rich in iron.It is the iron that enables the red blood cells to "carry" the oxygen by forming a chemical bond with the oxygen atom.
Answer: Plasma is the straw colored liquid portion of the blood that contains salts, proteins, water nutrients, hormones, and wastes. Here waste materials travel to the lungs, kidneys, and digestive system where they are removed from the body. Blood gets rid of carbon dioxide, ammonia, and many other waste products.
Answer: Veins and arteries carry the blood on a two way trip around the body. The arteries pump oxygenated blood to all the tissues throughout the body, then the veins simply carry the deoxygenated blood back to the heart. This blood is pumped to the lungs to get more oxygen and the arteries send them back through the body.
Answer: The molecules of oxygen stuck to special receptors in the blood (fueled by iron as a mineral). these receptors are called hemoglobine. Roughly, the less iron intake one has, the worse the passage of oxygen is, and such undernourished person may experience shortness of breath due to the lack of iron in his blood.
