When there is an inadequate amount of iron to form hemoglobin in erythrocytes

A hardening and thickening of the arterial walls is called

Contraction of the heart is known as

The valve that separates the left atria from the left ventricle is the

Formation of abnormally large and inadequate number of erythrocytes is known as

The medical term for the pacemaker of the heart is the

Impulses that are passed around the outer areas of the ventricles are carried by the

The impulses are carried from the atria to the ventricles by the

Dilated swollen veins that have lost elasticity and cause stasis or decreased blood flow are called

Injury to or the destruction of the bone marrow, leading to poor or no formation of the red blood cells

The lower part of the septum is called the interatrial septum

the right atrium receives oxygenated blood from the lungs

the period of ventricular contraction in the heart is called diastole

the aorta is the largest artery in the body

veins are more muscular and more elastic than other vessels

capillaries allow oxygen and nutrients to pass through to the cells because the walls of capillaries contain only one layer of cells

some capillaries contain valves

The average adult has nine to ten quarts of blood

Fibrinogen and prothrombin are blood proteins necessary for the clotting of blood

The red color of the blood is the result of hemoglobin carrying oxygen

The circulating form of erythrocytes does not have a nucleus

 Leukocytes can pass through capillary walls.

 Lymphocytes produce histamine and heparin.

A normal count for thrombocytes is 4500 to 11000.

Thrombocytes are fragments or pieces of cells.

Arrhythmias are abnormal heart rhythms caused by weak heart muscles.

A fixed pacemaker delivers electrical impulses only when the heart's conduction system is not responding correctly.

People with pacemakers should avoid close contact with digital telephones.

Hypotension is high blood pressure.

An aneurysm is a ballooning out or a saclike formation on the wall of the artery.

Anemias are low white blood cell counts.

Atherosclerosis occurs when fatty plaques are deposited on the walls of the arteries.

Angioplasty is used to remove or compress deposits in arteries or to insert a stent to allow blood flow.

 Phlebitis is inflammation of a vein.

 A thrombus is a blood clot.
