                                                      Blood and Body

               The average person has about one to one and a half gallons of a liquid inside its body called
               blood.  Blood  is  the  most  essential  and  important  part  of  the  body's  circulatory  system.  The
               circulatory system is responsible for the movement of blood throughout the body through blood
               vessels. The heart is the pump that makes it all happen.


               Blood  has  several  ingredients  found  inside  the  body  that  are  mixed  together.  Bone  marrow,
               located  inside  the  bones  of  the  body,  makes  most  of  these  ingredients  that  come  together  to
               produce blood. They include red blood cells, white blood cells, and platelets. In addition, a fourth
               ingredient called plasma, which is mostly water, is another important component of blood. Each
               of these components has a special function for the body.

               Red blood cells carry oxygen throughout the body. It is the most abundant of the different cells
               inside the blood. A chemical called hemoglobin is carried by the red blood cells and gives blood
               its  red  color,  and  carries  the  oxygen  too  all  parts  of  the  body.  The  hemoglobin  receives  the
               oxygen each time a person breathes.

               White blood cells help the body fight infections and are larger than red blood cells. They are not
               as abundant as red blood cells especially when a person is healthy. However, they increase in
               number when a person gets sick in order to fight off the illness. There are three kinds of white
               blood cells.


               Granulocytes help heal wounds after an injury, prevent infections, and kills germs before they
               enter the body. Lymphocytes include B cells and T cells. B cells help produce antibodies which
               gets rid of germs when a person like bacteria or viruses. These cells also help prevent a person
               from  getting  the  same  germ  in  the  future.  T  cells  also  battle  germs  by  producing  special
               chemicals to fight infections. Monocytes surround and destroy bacteria and viruses which can
               cause infections.


               Platelets are cells that help stop the body from bleeding if it gets cut. When a person's skin is
               broken  blood  vessels  are  also  cut.  The  platelets  send  out  a  chemical  signal  for  the  cut  to
               eventually clot and stop bleeding by sticking together. The blood vessels heal during the process
               of clotting. Without platelets the bleeding would never stop.
