my essay

My essay is dealing with the blood which is the most important fluid in our body and I select this subject because Im  interesting in the study of the body components and their functions.

Blood is a fluid that nurtures life, contains many enzymes and hormones, and transports O2 and CO2. In physiological conditions it may be considered as incompressible. This complex mixture has a number of functions in the body.

Functions of Blood:

1 - Transportation: of oxygen & carbon dioxide, nutrients, waste products (metabolic wastes, excessive water, & ions)

2 - Regulation - hormones & heat (to regulate body temperature)

3 - Protection - clotting mechanism protects against blood loss & leucocytes provide immunity against many disease-causing agents.

It may be considered as a connective tissue consisting of formed elements suspended in plasma. Plasma is mostly water but it also contains proteins, salts, nutrients, hormones, gases, vitamins, and metabolic wastes

Components of Blood - average adult has about 5 liters (about 5 qts) 

1 - Formed elements:

*      Red blood cells (or erythrocytes)

*      White blood cells (or leucocytes)

*      Platelets (or thrombocytes)

           2 - Plasma = water + dissolved solutes

My essay includes 5 chapters :

1-       composition of normal blood

2-      hematopoises (formation of blood cells )

3-      blood coagulation

4-      Blood as a tool in diagnosis of different diseases

5-      Common blood diseases
