Blood DisorderIron-deficiency anemia
Anemia is a condition in which the body does not haveenough healthy red blood cells.
Iron is a key part of red blood cells. Without iron, the blood cannot carry oxygen effectively.
Blood Functionleukocytes
Leukocytes -- a body's army of soldiers -- are a part of our immune system.
Blood Functionleukocytes
They fight the germs that cause disease and infections.
Some kill by completely devouring certain invaders
Blood Functionleukocytes
There are those who notify other leukocytes that an invasion has taken place.
If the immune system detects a harmful foreign object, such as bacteria or a virus, it will release histamine into nearby cells. The histamine causes imflamation.

Bacteria
Blood DisorderAllergy
An allergy is the response of the body's immune system to normally harmless substances, such as pollens, foods, and house dust mite.
Antihistamines work by stopping histamine affecting your body's cells in the usual way.
Blood DisorderLeukemia
Definition of leukemia: Cancer that starts in blood-forming tissue, such as the bone marrow, and causes large numbers of abnormal blood white cells to be produced and enter the bloodstream.
Blood Circulation
Systemic circulation (body circulation):Left ventricle,aorta, arteries, arterioles, capillaries, venules veins venae cavae. right atrium.
Blood Circulation
Pulmonary circulation (lung circulation)
Right ventricle of the heart.
de-oxygenated blood is pumped through the pulmonary arteries into the capillaries of the pumonary alveoli.
pulmonary veins.
Left atrium.
Arterial DiseaseAtherosclerosis
Atherosclerosis can narrows and blocks arteries in critical regions of the body.
Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood
Arterial DiseaseHypertension
Hypertension, also referred to as high blood pressure, is a condition in which the arteries have persistently elevated blood pressure.
Heart diseasesMyocardial Infarct
An area of the heart muscle doesn't get enough oxygen-rich blood.
If blood flow isn't restored quickly, the section of heart muscle begins to die.
