This document summarizes the different types of blood cells: red blood cells, white blood cells, and platelets. Red blood cells carry oxygen throughout the body via blood flow. They contain hemoglobin, an iron-containing molecule. White blood cells are involved in the immune system and protect the body against infection and foreign invaders. There are five types of white blood cells. Platelets function in blood coagulation and have a lifespan of 5-9 days. The main metal present in blood is iron, which is contained in red blood cells. A normal human has 5.78-6.21 liters of blood.

3. 1,Introduction
A).A blood cell , also called a haematopoietic cell ,
hemocyte , or hematocyte , is a cell produced through
Hematopoiesis and found mainly in blood.
B).Blood contain 45% of the blood tissues by volume ,
with remaining 55% of the volume composed of plasma.

4. 2.Typesofbloodcells
A),Redbloodcells-
Erythrocytes
B).Whitebloodcells-
Leukocytes
C).Platelets-Thrombocytes

5. 3.Red blood cells
1).Red blood cells are also called erythrocytes.
2).The Vertebrate’s principle means delivering
oxygen(O2) to the body tissues via blood flow
through the circulatory system.
3).RBCs take up oxygen in the lungs and release it
into body tissues.

3).The cytoplasm of erythrocytes is rich in Hemoglobin
an iron(Fe) containing biomolecule.
4).In the middle of red blood cell it contain iron (Fe) , it

8. .6).The number of erythrocyte is high in male [5.2
million] compare to the female [4.5 million].

10).The death of red blood cells is in spleen.
11).And also spleen used as the chamber of red
chamber of red blood storage,
12).Spleen also produce antibody to protect from the
bacteria fungi and etc…

10. 3.White blood cells
1).White blood cells are also called as leucocytes , are
the cells of immune system.
2).That are involved in protecting the body against
both infectious diseases and foreign invaders.
3).All white blood cells produced in bone marrow
known as hematopoietic stem cells.

4).All white blood cells have nuclei , which
distinguish from other blood cells.
5).There are five type of white blood cells.

16. 4.Platelets
1).Platelets are also called as thrombocytes.
2).Their function in the blood is coagulation factor.
3).Their life time is 5-9 days.
4).Their diameter is 2-3 micrometre.
5).Platelets are only found in mammals[e.g : birds
and amphibians].
