The Heart Flashcards
Serous fluid between the pericardial layer serve this function
Prevent friction
Divides the heart into right and left side
Aseptum
Amount of blood pumped by left ventricle in one minute
Cardiac output
Bottom of the heart
Apex
Name the parts of the electrical conduction system
SA node, AV node, AV bundle, precengy fibers
Circulates through the body
Systemic
The valves that allow blood to enter the ventricles
Triupsid it and bycupsid
No heart contraction
Asystole
Irregular variation in heart rate with breathing rate and depth
Sinus arrhythmia
Sequence of events in one heartbeat
Cardiac cycle
Pulmonary and systematic circulation is the reason that the body is supplied with
Oxygen
The artery that receives blood from the left ventricle
Aorta
Vein that returns blood from the upper body
Superior vena cava
Top of the heart
Base
What are the largest veins
Superior and inferior vena cava
Cardiac output is the product of
Heart rate and stroke volume
The SVC, IVC, and coronary sinus empty blood into
Right atrium
Inner level of the pericardial membranes
Visceral or epicardium
The left ventricle has a thicker muscle because it pumps blood to
The whole body
Blood vessels that supply heart muscles are
Coronary arteries
Abnormally fast heart rate
Tachycardia
This part of the ANS increases the heart rate
Sympathetic
Amount of blood pumped from the heart and one beat
Stroke volume
General function of the heart valves is
To prevent blood flow
Cranial nerve that slows the heart rate
Vegas
Blood vessels taking blood from right ventricle or chamber to the lungs is the
Pulmonary arteries
Dispensing or pumping chambers is the
Right and left ventricle’s
Layers of the heart from outside to inside
Epicardium, myocardium, endocardium
Abnormally slow heart rate
Bradycardia
The largest artery is the
Aorta
The endocardium is a smooth morning, why
So the blood flow will not clump
What merge to make the coronary sinus
Coronary veins
What is the cardiac control system
Medulla
Vein that drains blood from the lower body is the
Inferior vena cava
What side of the heart that has a low oxygen concentration in the blood
Right side
What is the term that means the heart is contracting
Systole
What is the term that means the heart relaxes
Diastole
What is the thick middle layer of the heart
Myocardium
Pacemaker
SA node
What is the receiving chamber
Right and left atrium
Valves by which the blood leaves the heart
Pulmonary or aortic valve’s
Inner lining of the heart chambers
Endocardium
Premature beat is a
Extra systole
In pulmonary circulation this pumps blood to the Veins
Right chamber or ventricle
The part of the ANS that slows the heart rate
Perisympathetic
To get the cardiac output what math will you use
Multiplication
Blood from fingers goes to inferior
False
Blood from pelvis strains to coronary sinus
False
Blood from heart muscle drains into SVC
False
Cardiac Output Formula
CO=HR x SV
