Introduction 

• Blood is a fluid tissue with many various functions. Not only important physiological process takes place in the blood but it determines the activity of widely separated body cells.
• Blood is composed of plasma and the corpuscular elements which are called red corpuscles or erythrocytes, white cor­puscles or leucocytes and blood platelets or thrombocytes.

Erythrocytes 

 

What is the size of red blood cells?7  8mkm diameter and the thickness of 2-2.5  microns

 

What increases the surface of red blood  cells?The absence of the nucleus and the  shape of a biconcave lens

 

What is the life span of red blood  cells?

Living at 100-120 days

 

Leucocytes 

 

How many white blood cells in 1mm3?In  1mm3 - 6 - 8tys.

 

What is the life expectancy of white  blood cells?From 10 days up to several  hours.

 

 Thrombocytes 

 

How many platelets in 1mm3? In 1mm3  up to 400 thousandWhat function is performed  by the platelets in the human body?The  main function is associated with the process  of blood clotting.

Conclusions:

 

The similarity of red blood cells

At a Glance

 

• It is generally considered that no sex differences exist in the count of white corpuscles or leucocytes. The count of leucocytes in the blood of a healthy person is 4,500 to 9,500 per cu mm (cubic millimetre). When the number of white blood cells (WBC) is counted after mental or physical exertion, meals and mild activity it may increase to 10,000 and more per cu mm.
• It is estimated that the erythrocytes are the most numer­ous cellular elements, ranging from 4,000,000 to 5,000,000 per cu mm. The red blood cell count (RBC) may change with age; when the red blood cell count is done after phys­ical exertion and emotions it may increase.

Conclusion

 

• The average human blood volume is not less than 7.5% but not more than 10% of the body weight. It is generally stated that the circulating volume averages smaller in the females than in the males. The circulating volume of the blood depends on the changes of the air temperature.
