Cardiovascular Test

QuestionAnswer
What covers the surface of the heart epicardium (visceral pericardium)
During a 1st degree heart block, electrical impulses move through the AV node
Will heart rate vary with body size and gender Yes
Abnormally rapid heart rate is called Tachycardia
Arrhythmia any deviation from the normal pattern of the heartbeat
Arterioles the smallest branch of an artery
The amount of blood pumped by each ventricle in one minute is known as Cardiac output
What would NOT be an effect on the heart rate if the SA node is not functioning Bradycardia
What is Rheumatic disease damage to the heart muscle and heart valves caused by episodes of rheumatic fever, caused by staph and strep
Angina pectoris is severe chest pain and constriction about the heart, usually radiating to the left shoulder and down the left arm creating a feeling of pressure in the anterior chest
Starling’s law of the heart changes force of myocardial contraction by stretch, an increase in stretch causes an increase in force of myocardial contraction and an increase in stroke volume
What valve is part of the two atrioventricular valves semilunar valve
Fetal circulation the system of blood vessels and structures through which blood moves in a fetus
Portal vein carries blood from the digestive tract to the liver
The hepatic portal vein is a major component of the hepatic portal system, one of the main portal venous systems in the body
Hepatic vein carries blood from the liver to the inferior vena cava
Hepatic artery brings oxygen-rich blood to the liver
Venules are the smallest veins which collect the deoxygenated blood from the cells for transport back to the heart
The blood flow sequence Right atrium » Tricuspid valve » Right ventricle » Pulmonic Valve » Pulmonary artery » Pulmonary capillaries » Pulmonary » Veins » Left atrium » Bicuspid (mitral) valve » Left ventricle » Aortic valve » Aorta
Systemic circulation circulation of blood from the left ventricle of the heart throughout the body and back to the right atrium of the heart
Arteries large thick-walled vessels that carry the blood away from the heart
Capillaries thin walls consisting of a single layer of endothelial cells
Veins transport the blood from the venules to the heart
How many layers of tissue is the heart composed of 3 Layers: 1.)Endocardium 2.)Myocardium 3.)Epicardium
What are the 4 chambers of the heart 1.) Right Atrium 2.) Right Ventricle 3.) Left Atrium 4.) Left Ventricle
What are the tough fibrous bands that hold the atrioventricular valves in place Chordae Tendineae
The right heart pumps the blood to where to the lungs
The left heart pumps the blood to where the rest of the body
Certain bacterial diseases may damage heart valves. Damage to the left semilunar valve interferes with blood flow into what chamber or vessel Aorta
What structures prevent AV valves from opening back into the atria Chordae tendineae and papillary muscles
Which two heart chambers contain oxygen-rich blood Left atrium and Left ventricle
What is another name for the SA node the pacemaker of the heart
What cause the myocardium to contract Electrical signals
What is the order of the conduction system SA node -> AV node-> Bundle of His -> Right and left bundle branches of His -> Purkinje fibers
What is the average rate of the SA Node 80 BPM
What is the average rate of the AV Node 40 - 50 BPM
What is happening to cause the Systole contraction or squeezing
What is happening to cause the Diastole relaxation
What is due to the vibrations caused by closure of the valves Lubb-dupp
Which part of the lubb-dupp is caused by the closure of the AV valves at the beginning of the ventricular systole Lubb
Which part of the lubb-dupp is caused by the closure of the semilunar valves at the beginning of the ventricular diastole dupp
What is the medical term for heart attack Myocardial Infarction
What is the medical term for the amount of blood ejected during one beat Stroke volume
What is the normal blood pressure 120/80
What is caused by the pumping of the heart or alternating expansion and recoil of the artery creating a pressure wave pulse
How much blood does the heart pump everday 7,200 quarts, approx. 5 quarts per minute or 2.5 ounces per beat
How many times does the heart beat everyday about 100,000 times
How big is the heart about fist size
what is the number of times the heart beats per minute Heart rate
What is responsible for pumping blood, carrying oxygen and removing carbon dioxide and other waste products cardiovascular system
what is between the chest and the lungs mediastinum
The area of the chest covering the heart precordium
The common wall between the left and right side of the heart septum
What enters the septum that separates the right and left ventricles bundle of his
What is defined as the pressure exerted by the blood on the walls of the arteries blood pressure
localized dilation of a weakened area of the wall of an artery. The weakened area balloons out with every pulsation of the artery aneurysm
What is the medical term for harding of the veins atherosclerosis
What is the medical term for elevated blood pressure hypertension
What is the medical term for low blood pressure hypotension
What is the medical term for decreased supply of oxygenated blood to a body part or organ ischemia
A low-pitched humming or fluttering sound heard on auscultation murmur
what is the medical term for urination at night nocturia
Medical term for pounding or racing of the heart palpitation
medical term for the formation or existence of a blood clot thrombosis
