My name is Count Dracula. I want to suck your blood. Oh, I thirst for even a single drop of blood. Blood is the elixir of life. It is very important to the human body.
Blood is made-up of plasma, red blood cells, white blood cells, and platelets.
The plasma is the carrier for blood cells, nutrients, enzymes and hormones. One type of the two types of blood cells is known as red bloods or erythrocytes. These red disc-shaped cells without a nucleus are produced in the bone marrow. These cells contain a very important chemical called hemoglobin. Hemoglobin gives the red color that we see in red blood cells.
