Which of these statements concerning the form and location of the heart are correct?
The apex is the most superior part of the heart.
The apex is directed to the left, and deep to the fifth intercostal space.
The base of the heart is directed inferior and slightly posterior.
The most superior part of the heart is deep to the 12th intercostal space.
Both the apex is the most superior part of the heart and the base of the heart is directed inferior and slightly posterior are correct.
The blood vessels that supply oxygenated blood to the heart tissue itself are the
pulmonary veins.
coronary arteries.
coronary sinuses.
pulmonary trunks.
venae cavae.
In a normal heart, when the right ventricle contracts, it forces blood through the:
tricuspid valve.
bicuspid valve.
aortic semilunar valve.
pulmonary semilunar valve.
The right side of the heart forces blood to flow
to the body.
to the lungs.
through the systemic circulation.
both to the body and through the systemic circulation.
both to the lungs and through the systemic circulation.
Tachycardia occurs when
the heart rate is less than 60 beats per minute.
the heart rate is more than 100 beats per minute.
ventricular fibrillation occurs.
ectopic beats occur in the atria.
Either the heart rate is more than 100 beats per minute or ectopic beats occur in the atria happen when tachycardia occurs.
The tricuspid valve:
is the location of the pacemaker cells of a normal heart.
prevents blood flow from the right ventricle to the right atrium.
prevents blood flow from the left ventricle to the left atrium.
prevents blood flow from the pulmonary artery to the right ventricle.
prevents blood flow from the aorta to the left ventricle.
The serous pericardium just internal to the fibrous pericardium is called:
the visceral pericardium.
the epicardium.
the parietal pericardium.
the parietal pleura.
Either the visceral pericardium or the epicardium is equally correct for this structure.
Which of these statements concerning the normal pathway of blood flow is NOT correct?
from the pulmonary arteries to the lungs
from the pulmonary veins to the right atrium
from the aorta to all parts of body except lungs
from the coronary sinus to the right atrium
Neither from the pulmonary veins to the right atrium nor from the coronary sinus to the right atrium are correct.
The following is a list of vessels and structures that are associated with the heart. 1) right atrium 2) left atrium 3) right ventricle 4) left ventricle 5) superior & inferior vena cava 6) aorta 7) pulmonary artery 8) pulmonary vein 9) mitrial/bicuspid valve 10) tricuspid valve 11) pulmonary semilunar valve 12) aorta semilunar valve What is the correct order for the flow of blood entering the heart from the LUNGS leaving for SYSTEMIC CIRCULATION (i.e. the body)?
8, 2, 9, 4, 12, 6
B) 8, 1, 10, 3, 11, 7
C) 5, 1, 10, 3, 11, 7
D) 7, 2, 9, 4, 12, 6
E) 6, 12, 1, 2, 10, 4
The ___________ is the sequence of events that occurs from the beginning of one heartbeat to the beginning of the next heartbeat, during which time the atria and ventricles contract, ensuring blood flow.
cardiac cycle
pulmonary cycle
systemic cycle
circulatory system
The left coronary artery has three major branches except:
anterior interventricular
posterior interventricular
circumflex
left marginal arteries
The right side of the heart receives blood from the body and pumps through _________ circulation to the lungs.
hepatic
pulmonary
peripheral
systemic
The delivery of oxygen and nutrients to the tissues of the body is accomplished through ________ circulation.
hepatic
pulmonary
peripheral
systemic
Which of the following is NOT true about the heart?
The heart is about the size of a closed fist.
The heart is located in the mediastinum.
The apex of the heart is directed superiorly and to the left.
Knowing the heart's position is important for effective CPR.
Another name for the visceral pericardium is the:
endocardium
epicardium
isocardium
myocardium
visocardium
From the right ventricle,blood flows directly into the _____.
aorta
right atrium
pulmonary trunk
pulmonary arteries
pulmonary veins
Which of the following lists the valves in the order through which the blood flows from the vena cava through the heart?
tricuspid, pulmonary semilunar, bicuspid, aortic semilunar
mitral, pulmonary semilunar, bicuspid, aortic semilunar
aortic semilunar, pulmonary semilunar, tricuspid, bicuspid
bicuspid, aortic semilunar, tricuspid, pulmonary semilunar
The P wave of an ECG indicates:
atrial depolarization
atrial repolarization
ventricular depolarization
ventricular repolarization
threshold
Which chamber initially receives blood from the systemic circuit?
left atrium
left ventricle
right atrium
right ventricle
All of the following are functions of the heart EXCEPT:
generation of blood pressure
ensures one way flow of blood
generation of the formed elements of the blood
regulates rate and force of blood delivery
distributes oxygenated blood to tissues
