Human Anatomy Heart Quiz

The heart is located in the middle of the thoracic cavity, specifically the middle mediastinum, resting on the diaphragm behind the sternum and slightly to the left.

A condition where the heart is positioned on the right side of the chest instead of the usual left.

The heart has four chambers: two atria (right and left) and two ventricles (right and left).

The right side of the heart, responsible for pumping deoxygenated blood.

The left side of the heart, responsible for pumping oxygenated blood.

The circulation of blood from the heart to the lungs and back to the heart.

The circulation of blood from the heart to the body and back to the heart.

The surface of the heart facing the sternum and ribs.

The part of the heart resting on the diaphragm, with a groove for blood vessels (posterior interventricular groove).

Mostly formed by the left atrium, a chamber of the heart.

Part of the ventricle, located at the 5th intercostal space, 9 cm from the midline; important for auscultation (listening to heart sounds).

The origin of major blood vessels (aorta, pulmonary trunk, and superior vena cava) from the heart.

Formed by the right atrium; extends between the superior and inferior vena cava.

Mostly formed by the right ventricle and extends towards the apex.

Mainly formed by the left ventricle and the left auricle.

Visceral layer of pericardium + adipose tissue, crucial in insulating and protecting the heart.

Cardiac muscle tissue (around 95%) responsible for the heart's pumping action.

Inner lining of the heart chambers, a single layer of flat cells+thin CT; reduces friction for smooth blood flow.

Receives deoxygenated blood from the body and heart muscle via 5 veins; has a smooth-walled chamber and a rough-walled pouch (auricle).

Brings deoxygenated blood from the upper body into the right atrium.

Brings deoxygenated blood from the lower body into the right atrium.

The opening between the atrium and ventricle, allowing blood flow from the atria to the ventricle of the heart.

A valve located at the A-V orifice in the right side of the heart that controls blood flow between the right atrium and right ventricle.

A vessel that drains deoxygenated blood from the heart wall back into the right atrium.

Finger-like projections in the ventricles that secure the valve cusps during contraction, preventing backflow.

A septum wall structure connecting to the anterior papillary muscle. It has a nerve bundle to the right ventricle wall.

Prominent muscular ridges in the ventricles.

The funnel-shaped upper section of the right ventricle, leading to the pulmonary artery.

The opening from the right ventricle to the pulmonary artery (carrying deoxygenated blood to the lungs).

The valve guarding the pulmonary orifice, preventing backflow from the pulmonary artery.

Heart chamber that receives oxygenated blood from the lungs.

Small appendage of the left atrium.

Chamber that pumps oxygenated blood to the body.

Smooth-walled area for outflow in the left ventricle, leading to the aorta.

The valve between the left atrium and ventricle preventing backflow.

Valve guarding the aorta from backflow during ventricular relaxation.

Partition between left and right ventricles.
