QuestionChoice
The interventricular septum sits between the right and left ventricle. It can be further divided into a muscular portion and a membranous portion. The interventricular septum essentially marks the boundary between the left and right ventricles. The membranous portion is where most defects of the septum can occur.

d
Contains an interventricular septum within its walls
QuestionChoice
The pulmonary arteries carry deoxygenated blood from the right ventricle towards the lungs to collect oxygen. The four pulmonary veins carry oxygenated blood from the lungs to the heart, and empty directly into the left atrium.

b
The structure receives oxygenated blood from four pulmonary arteries.
QuestionChoice
The left atrium is labelled. The four pulmonary veins carry oxygenated blood from the lungs to the heart, and empty directly into the left atrium. The four pulmonary veins drain the following regions:
* Right superior pulmonary vein: right upper and middle lobes
* Right inferior pulmonary vein: right lower lobe
* Left superior pulmonary vein: left upper lobe
* Left inferior pulmonary vein: left lower lobe

a
The structure receives oxygenated blood from four pulmonary veins.
QuestionChoice
This answer describes the tricuspid valve, which is located between the right atrium and the right ventricle. The chordae tendinae are strong fibrous bands of tissue that join the valve leaflets and papillary muscles to allow for valve leaflet closure.
