Circulatory system
Circulatory system transports food (nutrients), oxygen to cells of our body.
It also transports carbon dioxide from cells to heart and then walls of lungs.
Veins carry impure or carbon dioxide rich blood from cells of the body to the heart.
Arteries carry pure or oxygen-rich blood from the heart to different parts of the body.
Capillaries are smallest of all blood vessels that form the connection between veins and arteries.
White blood cells are the cells of immune system. They protect the body against infectious diseases.
Haemoglobin gives blood its red color. Haemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also help in removing carbon dioxide from the body.
Platelets help our body to repair itself when we get hurt. They cause our blood to clot so that we stop bleeding when we get a cut.
