At times one may be seen shaped like a dumb-bell, half of it through the wall of the blood vessel and half still in the blood vessel. After the corpuscle is out, no hole can be found to account for its mysterious passage. The ^cvJdte corpuscles consist of protoplasm. TJie red corpuscles contain no protoplasm. Hence tJie latter are not really alive. The Use of Each Part of the The plasma keeps the blood in a liquid state, so that it may flow readily; the plasma also transports the food that has been eaten and digested, and carries carbon dioxid to the lungs and other waste material to the kidneys.
