Chapter 13 - Cardiovascular Health and Cancer Flashcards
Cardiovascular Disease (CVD)
The collective term for various diseases of the heart and blood vessels.
Cardiovascular System (CVS)
The system that circulates blood through the body; consists of the heart and blood vessels.
Pulmonary Circulation
The part of the circulatory system controlled by the right side of the heart: the circulation of blood between the heart and the lungs.
Systemic Circulation
The part of the circulatory system controlled by the left side of the heart: the circulation of blood between the heart and the rest of the body.
Superior Vena Cava
Either of two large veins (superior vena cava and inferior vena cava) through which blood is returned to the right atrium of the heart (plural, venae cavae). Above diaphragm.
Inferior Vena Cava
Either of two large veins (superior vena cava and inferior vena cava) through which blood is returned to the right atrium of the heart (plural, venae cavae). Below diaphragm.
Right Atrium
Either of the two upper chambers of the heart (left or right) in which blood collects before passing to the ventricles (plural, atria).
Right Ventricle
Either of the two lower chambers of the heart (left or right) that pump blood to the lungs and other parts of the body.
Left Atrium
Either of the two upper chambers of the heart (left or right) in which blood collects before passing to the ventricles (plural, atria).
Left Ventricle
Either of the two lower chambers of the heart (left or right) that pump blood to the lungs and other parts of the body.
Aorta
The largest artery in the body; receives blood from the left ventricle and distributes it to the body.
Path of Blood Flow
1.Veins
2. Inferior and Superior Vena Cava
3. Right Atrium
4. Tricuspid Valve
5. Right Ventricle
6. Pulmonary arteries
7. Left Atrium
8. Mitral Valve
9. Left Ventricle
10. Aorta
11. Arteries
Systole
The contraction phase of the heart. Blood pumps out of the heart.
Diastole
The relaxation phase of the heart. The heart fills with blood.
Blood Pressure
The force exerted by the blood on the walls of the blood vessels; created by the pumping of the heart and the resistance of the blood vessels.
True or False? In the US, 1 in 5 deaths are due to heart disease.
True
Veins
A vessel that carries blood to the heart.
Arteries
A vessel that carries blood away from the heart.
Capillaries
A small blood vessel that exchanges oxygen and nutrients between the blood and the tissues.
Coronary Arteries
A blood vessel branching from the aorta that provides blood to the heart muscle.
Atherosclerosis
Cardiovascular disease caused by the deposit of fatty substances (called plaque) in the walls of the arteries.
Plaques
A deposit on the inner wall of blood vessels; blood can coagulate around plaque and form a clot.
Coronary Heart Disease (CHD)
Cardiovascular disease caused by hardening of the arteries that supply oxygen to the heart muscle; also called coronary artery disease.
Heart Attack
Damage to, or death of, heart muscle, resulting from a failure of the coronary arteries to deliver enough blood to the heart; also known as myocardial infarction (MI).
Heart Attack Symptoms
- Chest Pain or Pressure
- Arm, neck, or jaw pain
- Difficulty Breathing
- Excessive Sweating
- Nausea and Vomiting
- Loss of Consciousness
Angina Pectoris
Chest pain due to coronary heart disease.
Arrhythmias
A change in the heartbeat’s normal, regular pattern.
Sudden Cardiac Death
A nontraumatic, unexpected death from sudden cardiac arrest, most often due to arrhythmia; in most instances, victims have underlying heart disease.
Ventricular Fibrillation
A heart rhythm that leads to ineffective bloodflow, most often cause of cardiac arrest.
Cardiopulmonary Resuscitation (CPR)
A technique involving mouth-to-mouth breathing and/or chest compressions to keep oxygen flowing to the brain.
Angiogram
A picture of the arterial system taken after injecting a dye that is opaque to X-rays.
Ballon Angioplasty
A technique in which a catheter with a deflated balloon on the tip is inserted into an artery; the balloon is then inflated at the point of obstruction in the artery, pressing the plaque against the artery wall to improve blood supply.
Coronary Bypass Surgery
Surgery in which a blood vessel is grafted from the aorta to a point below an obstruction in a coronary artery, improving the blood supply to the heart.
Stroke
Impeded blood supply to some part of the brain, resulting in the destruction of brain cells; also called a cerebrovascular accident (CVA).
Helping A Heart Attack Victim
- Call for help (911)
- Chew and swallow an adult aspirin
- If victim loses consciousness and there is no pulse administer Cardiopulmonary Resuscitation (CPR)
Ischemic Stroke
Impeded blood supply to the brain caused by a clot obstructing a blood vessel.
Thrombus
A blood clot that forms in a blood vessel that has already been damaged by plaque buildup; the clot may lead to stroke.
Thrombotic Stroke
Embolus
A blood clot that breaks off from its place of origin in a blood vessel and travels through the bloodstream.
Embolic Stroke
Hemorrhagic Stroke
Impeded blood supply to the brain caused by the rupture of a blood vessel.
Aneurism
A sac or outpouching formed by a distention or dilation of the artery wall.
