Blood
Blood is this type of tissue
What is connective tissue?
This muscular wall separates the left and right sides of the heart.
What is septum?
Commonly called "bypass surgery," this procedure (CABG) reroutes blood around clogged arteries.
What is Coronary Artery Bypass Grafting?
In a reading of 120/80, 120 represents this "top" number, occurring when the heart contracts.
What is Systolic?
Unlike arteries, most of these vessels contain one-way valves to prevent the backflow of blood.
What are veins?
These "red" cells use hemoglobin to transport oxygen throughout the body.
What is O-Negative?
The heart has four of these; the mitral and tricuspid are two examples.
What are valves?
This test uses sound waves (ultrasound) to create live images of the heart's chambers and valves.
What is Echocardiogram?
This is the medical term for chronically high blood pressure.
What is Hypertension?
These microscopic vessels are the site where gas and nutrient exchange actually occurs.
What are Capillaries?
These small, colorless cell fragments are essential for blood clotting, or hemostasis.
What are platelets (Thrombocytes)?
This is the largest artery in the body, exiting directly from the left ventricle.
What is aorta?
A tiny wire mesh tube used to keep a narrowed artery open after angioplasty.
What is Stent?
This standard medical instrument is the technical name for a blood pressure cuff.
What is Sphygmomanometer?
This is the innermost layer of a blood vessel, composed of a single layer of endothelial cells.
What is Tunica Intima?
This straw-colored liquid component makes up about 55% of total blood volume.
What is plasma?
Often called the "pacemaker," this node initiates the electrical impulse for a heartbeat.
What is sinoatrial (SA) node?
This emergency procedure uses an electric shock to reset a heart experiencing lethal arrhythmia.
What is Defibrillation?
These receptors, located in the carotid sinus and aortic arch, sense changes in blood pressure.
What are Baroreceptors?
These "resistance vessels" are small branches of arteries that lead to capillaries.
What are Arterioles?
This hormone, produced mainly by the kidneys, stimulates the production of red blood cells.
What is erythropoietin (EPO)?
These "heart strings" are fibrous cords that connect papillary muscles to the AV valves.
What are chordae tendineae?
This diagnostic process involves threading a thin tube through a blood vessel to the heart to check for blockages.
What is Cardiac Catheterization?
This "bottom" number in a BP reading represents the pressure in the arteries while the heart rests between beats.
What is Diastolic?
This large vein carries deoxygenated blood from the lower half of the body back to the right atrium.
What are Inferior Vena Cava?
