The semi lunar (SL) valves are the:
|
Aortic and pulmonic valves
|
|
|
The tricuspid valve is on the _____ side of the heart
|
right
|
|
|
The bicuspid OR mitral valve is on the __________ side of the heart
|
left
|
|
|
The 2 AV OR arterio ventricular valves are the:
|
Tricuspid and Mitral valve
|
|
|
The AV valves open during _________ to allow the ventricles to fill up with blood
|
diastole
|
|
|
The SL valves open during ___________ to allow blood to be ejected throughout the heart
|
Systole
|
|
|
The pulmonic vavle is on the ________ side of the heart
|
right
|
|
|
The aortic valve is on the __________ side of the heart
|
left
|
|
|
The heart extends to the ____ & _____ intecostal space (ICS) and from the right border of the sternum to the left ___________ line
|
2nd
5th midclavicular |
|
|
During a contaction the apex beats against the chest wall producing and ___________ impulse
|
apical
|
|
|
The ___________ side of the heart pumps blood into the lungs, at the same time the _______ side pumps blood into the body
|
right
left |
|
|
Name the 2 phases of the cardiac cycle
|
Diastole
Systole |
|
|
During diastole the ___________ relax and fill with blood
|
ventricles
|
|
|
The closure of the __________valves signals the begining of systole
|
AV
|
|
|
The closure of the ________ valves contribute to the first heart sound S1
|
AV
|
|
|
The _________valves close and this causes the 2nd heart sound S2.
|
SL
|
|
|
The cardiac sound is produced from 2 basic mechanisms:
|
1.) The sudden acceleration or deceleration of blood, which is mainly influenced by the opening and closing of heart valves and the sudden tension of intra cardiac structures.
2.) Turbulent blood flow produced when anatomically there is narrowing; flow into a distal chanber of larger diameter than the proximal chamber; flow into a distal chamber of smaller diameter than the proximal chamber; high flow rates; and abnormal communication between chambers as in atrial or ventral septal defects. |
|
|
S3 is a result of:
|
decrease ventricular compliance or increase ventricular diastolic volume.
|
|
|
The 2 sounds that make up s2 are:
|
A2= the closure of the aortic valve.
P2= the closure of the pulmonic valve. |
|
|
P2 is the softer of the 2 sounds and usually only audible at the base __________.
|
left
|
|
|
If the both the 2 components that make up S2 are audible (P2 & A2) searately this is known as
|
physiological split
|
|
|
the normal physiological split of S2 is heard on ___________; it becomes single on _____________
|
inspiration
expiration |
|
|
During inspiration there is a ____________ in intrathoracic pressure that permist and increase in venous return to the right atrium.
|
decrease
|
|
|
The absence of an audible split on inspiration does not indicate pahtology, but a distinctly audible splitting of S2 on_____________ is abnormal
|
expiration
|
