Anatomy of the Heart
Wide margin at the top of heart
Base
Abnormally fast heartbeat, >100 beats per minute when at rest.
Tachycardia
Normal blood pressure is 120/70 mmHg
False, 120/80 mmHg
What is the most common site to take a pulse?
Radial Artery
The middle layer; composed of cardiac muscle tissue
Myocardium
Receives oxygen-poor blood from 2 large veins, the superior and inferior venae cavae.
Right Atrium
Blocked coronary circulation, causes plaque and blood clots
Myocardial Infraction (Heart Attack)
Electrical changes during atrial depolarization happens during the P wave
True
The heart pumps about how many liters of blood through the body a day?
7,000
Conducts impulses from SA Node to AV Bundle.
AV (Atrioventricular) Node
Transport oxygen-rich blood back from lungs to left atrium of heart.
Pulmonary Veins
Degenerative condition on which the coronary arteries become thickened and hard, and narrowed due to deposition of fatty plaque in their walls.
Coronary Artery Disease
SA Node is the pace maker
True
The heart pumps blood through the arteries, then arterioles, and then what...
capillaries
What is a heart murmur? Why is it occurring?
Abnormal heart sound. Incomplete closure of cusps of a valve.
Muscular sheet between the left and right atrium.
Interatrial Septum
Artificial Pacemaker
In the blood flow through the heart after blood goes through the pulmonary vein it goes to the right atrium.
False, it goes to the left atrium.
The base of the heart lays beneath what rib
2nd rib
Large fibers that conduct impulses to ventricular myocardium.
Purkinje Fibers
Opening between the left and right atria of the fetal heart.
Foramen Ovale
Inflammation of a vein
Phlebitis
About 65% of the blood is found in the systemic veins.
True
Inner layer of the heart
endocardium
Joins the carotid and vertebral artery systems.
Cerebral Arterial Circle (Circle of Willis)
