Its a two layered serous sac that surrounds the heart and the root of the great vessels

The great vessels that originate from the heart radiate their branches to...

The pericardium is composed of both fibrous pericardium and serous pericardium

Its tough connective tissue

Its thin and consists of a parietal and visceral layer

Lines the inner surface of the fibrous pericardium

Adhered to the heart and forms its outer covering

Branches from the internal thoracic pericardiophrenic, musculophrenic, and inferior phrenic arteries, and the thoracic aorta.

Azygous system of veins and the internal thoracic and superior phrenic veins

Vagus nerve, the sympathetic trunks and phrenic nerves

Heart orientation that projects forward, downward, and to the left

Quadrilateral and faces the posterior direction

The base of the heart is opposite to the apex

Consists of the left atrium, small portion of the rights atrium and proximal parts of the great veins

Formed by the inferolateral part of the left ventricle. Positioned deep into the left 5th intercostal space midclavicular line

Faces anteriorly and consist mostly of the right ventricle

Faces the left lung, broad and convex, and consists of the left ventricle and a portion of the left atrium

Faces the right lung, is broad and convex and consist of the right atrium

The heart consists of a single chamber and pump

Receives deoxygenated blood from the body and sends it to the lungs

Receives oxygenated blood from the lung and sends it to the body

What does each pump of the heart consist of?

What separates the four chamber of the heart?

Receives deoxygenated blood from the body via SVC, IVC, and coronary sinus

Receives oxygenated blood from the lungs via pulmonary veins

Received deoxygenated blood from the right atrium via right atrioventricular orifice and sends it to the lungs via pulmonary trunk

Receives oxygenated blood from left atrium via left atrioventricular orifice and sends it to the body via aorta

What separates the atria from ventricles and ventricles from great vessels?

This heart valve prevents back flow from the ventricle to the atria

This heart valve prevent back flow from the great vessels to the ventricles

They're fibrous cords that connect the papillary muscles of the ventricular walls to the atrioventricular valves and prevent the backward prolapse of the cusps.

Fibrous structural support for the heart chambers that consist of dense, fibrous connective tissue in the form of four rings with interconnecting areas between the atria and the ventricles

Located between the aortic ring and right atrioventricular ring

Located between the aortic ring and the left atrioventricular ring

The coronary arteries arise from the aortic sinuses at the beginning of the ascending aorta, and then circle the heart

How many coronary arteries are there?

Blood is moved from the left and right ventricles to the aorta and pulmonary vein

They're a network of specialized cells located in the subendocardial surface of the ventricular walls. Their rapid conduction allows coordinated ventricular contraction

Decreases HR, Reduces force of contraction and constricts the coronary arteries

Increases HR and increases the force of contraction

Considered the largest artery in the body

Carries oxygenated blood to the rest of the body, arises from the aortic orifice at the base of the left ventricle, via aortic valve.

Located within the pericardial sac

Begins at the junction of the two brachiocephalic veins

Passes through the fibrous pericardium and enters the right atrium

Formed in the pelvis by the common iliac veins

Passes through the diaphragm (T12), enters the fibrous pericardium and enters the right atrium
