Term
The heart wall is made of 3 layers
Definition
epicardium, myocardium and endocardium
Term
The heart contains 4 chambers
Definition
the right atrium, left atrium, right ventricle, and left ventricle.
Term
The heart valves can be broken down into two types
Definition
atrioventricular and semilunar valves
Term
The AV valve on the right side of the heart is called
Definition
the tricuspid valve
Term
The AV valve on the left side of the heart is called
Definition
the mitral valve
Term
The AV valves are attached on the ventricular side to tough strings called
Definition
chordae tendineae
Term
The semilunar valve on the right side of the heart is
Definition
the pulmonary valve
Term
The semilunar valve on the left side of the heart is
Definition
the aortic valve
Term
The chambers on the right side of the heart are (1) and have (2) in their heart wall when compared to the left side of the heart.
Definition
(1) smaller
(2) less myocardium
Term
The conduction system starts with the pacemaker of the heart—a small bundle of cells known as
Definition
the sinoatrial (SA) node
Term
The SA node is located in
Definition
the wall of the right atrium inferior to the superior vena cava
Term
The signal from the SA node is picked up by another mass of conductive tissue known as
Definition
the atrioventricular (AV) node
Term
The AV node is located in
Definition
the right atrium in the inferior portion of the interatrial septum
Term
The AV bundle is a strand of conductive tissue that runs through
Definition
the interatrial septum and into the interventricular septum
Term
At any given time the chambers of the heart may found in one of two states
Definition
1 Systole
2 Diastole
Term
During systole, cardiac muscle tissue
Definition
is contracting to push blood out of the chamber
Term
During diastole, the cardiac muscle cells
Definition
relax to allow the chamber to fill with blood
Term
There are 3 phases to the cardiac cycle
Definition
atrial systole, ventricular systole, and relaxation
Term
Atrial systole: To facilitate this filling, the AV valves stay (1) and the semilunar valves stay (2)
Definition
(1) open
(2) close
Term
Ventricular systole:The pressure of the ventricles forces the semilunar valves to (1) and the AV valves to (2)
Definition
(1) open
(2) close
Term
During the atrial systole phase of the cardiac cycle, the atria contract and push blood into
Definition
the ventricles
Term
During ventricular systole, the ventricles contract to push blood into
Definition
the aorta and pulmonary trunk
Term
During ventricular systole, the ventricles contract to push blood into
Definition
the aorta and pulmonary trunk
Term
Deoxygenated blood returning from the body first enters the heart from
Definition
the superior and inferior vena cava
Term
From the pulmonary veins, blood enters the heart again in
Definition
the left atrium
Term
The left atrium contracts to pump blood through the (1) into the (2)
Definition
(1) mitral valve
(2) left ventricle
