The Heart: Structure and Function
This is the thin outer layer of the heart wall.
Epicardium
These vessels carry blood away from the heart and have thick walls to withstand pressure.
Arteries
This clear, pale-yellow fluid is formed after blood clotting and is used in many chemistry and immunology tests.
Serum
This condition causes chest pain due to reduced blood flow to the heart muscle, often from narrowed coronary arteries.
Angina Pectoris (Angina)
This blood disorder is characterized by a low red blood cell count.
Anemia
These are the upper chambers of the heart that receive blood.
Atria
The blood vessels that connect arterioles and venules and are microscopic
Capillaries
These are the most numerous blood cells, are anuclear, and function to carry oxygen.
Erythrocytes (Red Blood Cells)
This common heart disorder is characterized by plaque buildup that reduces blood flow in the arteries.
Coronary Artery Disease (CAD)
A form of cancer involving white blood cells.
Leukemia
This is the thick, muscular middle layer of the heart wall.
Myocardium
This type of circulation carries oxygenated blood from the left ventricle to the rest of the body.
Systemic Circulation
Also known as platelets, these small formed elements play a crucial role in hemostasis.
Thrombocytes
A heart attack resulting from a complete obstruction causing tissue death is known as this.
Myocardial Infarction (MI)
This blood disorder is characterized by low platelet count
Thrombocytopenia
This term describes the relaxation phase of the cardiac cycle.
Diastole
This is the internal space of a vessel where blood flows.
Lumen
In the ABO blood group system, this blood type has A and B antigens but no antibodies.
Type AB
This refers to a narrowing of the aortic valve opening
Aortic Stenosis
This disorder is characterized by abnormal hemoglobin, leading to sickle-shaped red blood cells.
Sickle Cell Anemia
This term describes one complete contraction and relaxation of the heart.
Cardiac Cycle
The middle and thickest layer of arteries and veins, composed of smooth muscle and elastic fibers.
Tunica media
Individuals with Rh– blood can become sensitized by Rh+ blood, which can lead to this disease in a fetus during future pregnancies.
Hemolytic Disease of the Newborn
This heart disorder involves poor pumping leading to fluid buildup.
Congestive Heart Failure
This type of cancer specifically affects plasma cells.
Multiple Myeloma
