Chapter 7 Flashcards
Cardiovascular
Heart and blood vessels
Lymphatic
Structures involved in the conveyance of the fluid lymph
Circulatory system
Consists of cardiovascular and lymphatic systems
What are the six (6) functions of the cardiovascular system?
- Supply body cells with needed substances
- Transports waste products for disposal
- Maintains the acid-base balance of the body
- Prevents hemorrhage through blood clotting
- Protects against disease
- Helps regulate body temperature
Arteries
How oxygen rich blood leaves the heart
Arterioles
When arteries branch many times
Capillaries
When arterioles branch into tiny vessels with one-cell thick walls
Venules
The way for blood leaving the capillaries to return to the heart
Veins
Carry blood back to the heart
Venae Cavae
The large vein that leads into the heart.
Atrial
Pertaining to the atrium
Ventricular
Pertaining to the ventricle
Atrioventricular Valves (AV)
Valves between the atria and ventricles
Tricuspid Valve
Right AV valve
Mitral/Bicuspid Valve
Left AV valve
Cuspid

Semilunar
Valves that have the appearance of a half-moon when the valves are closed (Aortic and Pulmonary semilunar valves)
Pericardium
A sac made up of a double membrane, encloses the heart.
Visceral/Epicardium
The innermost layer of the pericardium
Endocardium
Forms the lining inside the heart
Myocardium
The heart muscle itself. This is the thickest tissue of the heart and is composed of muscle fibers that contract, resulting in the squeezing of blood from the heart with each heartbeat.

Record of the heart obtained by directing ultrasonic waves through the chest wall.
Cardiac catherterization
The passage of a long, flexible tube into the heart chambers through the vein in an arm, leg, or neck. Allows for collection of blood samples from different parts of the heart and determines pressure differences in chambers. Inside of the heart can be viewed.
Positron Emission Tomography (PET)
Helpful in examining blood flow in the heart and vessels. Patient is injected with a radioactive dye and images are produced.
Angina Pectoris
Severe chest pain and constriction about the heart caused by an insufficient supply of blood to the heart itself
Arrhythmia
Irregularity or loss of rhythm of the heartbeat. (Dysrhythmia is more technically correct)
Cardiomeglay
Enlarged size of the heart
Congenital Heart Defects
Abnormalities present in the heart at birth. (Often involve the septum)
Congestive Heart Failure (CHF)
Condition characterized by weakness, breathlessness, and edema in lower portions of the body. (The work demanded of the heart is greater than its ability to perform) AKA: Congestive Heart Disease
Heart Failure
Heart fails to pump properly
Coronary Artery Disease (CAD)
Abnormal condition that affects the heart’s arteries and produces various pathologic effects, especially the reduced flow of blood to the myocardium. (Flow or blockage issue)
Coronary Heart Disease (CHD)
Heart damage resulting from insufficient oxygen cause by pathologic changes in the coronary arteries.
Fibrillation
Severe Cardiac arrhythmia in which contractions are too rapid and uncoordinated for effective blood circulation. It can sometimes be reversed by a defibrillator.
Defibrillator (For defibrillation)
Electronic apparatus that delivers a shock to the heart, often through electrode to the chest. can also be used to slow the heart or restore to normal rhythm.
Heart Murmur
Soft blowing or rasping sound that may be heard when listening to the heart with a stethoscope, not necessarily pathogenic.
Hyperlipidemia
Excessive lipid (fats) in the blood. An elevated blood level of one type of lipid, cholesterol, is associated with an increased risk of developing CHD in most individuals.
Hypertension
Elevated blood pressure above the normal values of 120/80 mm Hg in an adult over the age of 18 years old. (A person with hypertension is said to be hypertensive.
Hypotension
Low blood pressure. A blood pressure of 95/60 mm Hg indicates hypotension.
Infarction
Necrosis of a localized area of tissue caused by lack of blood supply to that area. Can be caused by Occlusion or stenosis of the artery that supplies blood to that tissue.
Occlusion
Obstruction
Stenosis
Narrowing
Myocardial Infarction (MI)
The death of an area of the heart muscle that occurs as a result of oxygen deprivation. AKA Acute myocardial infarction (AMI)
Myocardial Ischemia
Deficiency of blood supply to the myocardium. (The word ischemia refers to a temporary deficient of blood supply to any part of the body)
Septal Defect
Defect in the wall separating the left and right sides of the heart. The defect is usually congenital and is either an atrial septal defect (ASD) or ventricular septal defect (VSD)
Shock
Serious condition in which blood flow to the heart is reduced to such an extent that body tissues do not receive enough blood. This condition can result in death. May be caused by hemorrhage, infection, drug reaction, injury, poisoning, MI, or excessive emotional stress.
Vasodilation
Increase in the diameter of a blood vessel
Vasoconstriction
Decrease in the diameter of a blood vessel
