Atherosclerosis
Is a type of hardening of arteries characterized by the formation of
fibrofatty lesion in the intimal lining of the large and medium-sized
arteries such as aorta and its branches, the coronary arteries and large
vessels that supply the brain
The Neoplastic disorders include:
Leukemias
Lymphomas
Multiple Myeloma
Leukemias
◆ Leukemias are malignant tumors of the haemopoitic stem cells
The function of RBC, facilitated by hemoglobin molecule,
is to transport oxygen to the tissue.
Oxygen is poorly soluble in plasma, So about 95%-98% is
carried bound to hemoglobin.
Disorders of Red Blood Cells
The Hb molecule is composed of
Loss of normal immune response due to deficiency in either general
or special defense mechanisms is called immunodeficiency.
Deficiency of general defense mechanisms like defect in inflammation,
deficiency In Phagocytosis system, abnormality in the integrity of natural

Chronic Inflammation

1. Progressive acute inflammation.
2. Primary chronic inflammation.

Genes and Genetic Diseases
Gene: Is a fundamental unit of information storage.
Genes control inheritance and function of all the cells in the body e.g.
Genes control the type and quantity of hormone.
