Systemic & Coronary Circulation | Position of the Heart | Pericardium | Chambers & Valves | Fact Check |
---|---|---|---|---|
Left
Systemic circulation moves oxygenated blood from the ______ side of the heart through blood vessels to systemic cells
|
The inferior border & right border
______ is formed by the right ventricle & ______ the formed by right atrium & ventricle is located anteriorly
|
The pericardium
Restricts the heart’s movements so that it doesn't bounce like a child in a bouncy house within the thoracic cavity
|
Closing of the atrioventricular valve
What valve produces the S1 sound (lubb)?
|
Clenched fist
The heart is about the size of a person's?
|
Right
Pulmonary circulation moves deoxygenated blood from the ______ side of the heart through blood vessels to the lungs
|
The left border
What is formed by the left atrium & ventricle is located posteriorly
|
Serous pericardium
A thin, double-layered serous membrane
|
Closing of the semilunar valve
What valve produces the S2 sound (dupp)?
|
Diseases
What causes the heart size to increase?
|
True
True or false: Nutrients are exchanged with the systemic cells before blood is returned to the right side of heart.
|
Superior border
What border is formed by great arterial trunks (ascending aorta & pulmonary trunk) & superior vena cava
|
Epicardium & the parietal layer
The layers of the Serous pericardium are?
|
Aortic semilunar valve
______ is best heard in the 2nd intercostal space right of the sternum
|
Angiogram
What is used to view coronary circulation?
|
Blood pressure
______ is the force of the blood pushing against the inside walls of the vessels
|
The base
Posterosuperior surface of the heart formed by the left atrium; bordered by pulmonary veins that enter the left atrium
|
Pericardial cavity
The narrow space between the parietal & visceral layers of the serous pericardium.
|
The left atrioventricular valve, right atrioventricular valve
______ is best heard near the apex of the heart while the ______ is best heard at the interior left sternal border in the 5th intercostal space
|
Fibrous skeleton
Electrical insulator to prevent action potentials in the atria from passing to the ventricles, so that the ventricles don't contract at the same time as atria
|
Systemic
The right atrium receives venous blood from the ______ circulation and the heart muscle itself
|
Heart
The ______ located on the left of the body midline posterior to the sternum in the mediastinum (median space of thoracic cavity)
|
Fibrous pericardium
A tough, dense connective tissue layer that is attached inferiorly to the diaphragm & superiorly to the base of the great vessels.
|
Pulmonary semilunar valve
______ is best heard in the 2nd intercostal space left of the sternum
|
Fibrous skeleton
When the atria contract, the ______ compress the walls of the chambers inward to move the blood into the ventricles.
