Superior vena cava: 

1. The superior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the head and upper body feed into the superior vena cava, which empties into the right atrium of the heart.

Pulmonary Semilunar Valve: The pulmonary valve (sometimes referred to as the pulmonic valve) is the semilunar valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. Similar to the aortic valve, the pulmonary valve opens inventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.

right atrium:

1. Deoxygenated blood inters the right atrium through the inferior and superior vena cavas. The right side of the heart then pumps this deoxygenated blood into the pulmonary veins around the lungs.

 right atrioventricular canal:The proper development of the atrioventricular canal into its prospective components (The heart septum and associated valves) to create a clear division between the four compartments of the heart and ensure proper blood movement through the heart, are essential for proper heart function. 

right atrioventricular valve: regulates how blood flows thru the canal

chordae tendineae: The chordae tendineae (tendinous chords), or heart strings, are cord-like tendons that connect the papillary muscles to thetricuspid valve and the mitral valve in the heart.

right ventricle: pumps blood into the pulmonary trunk papillary muscles: contract when ventricles contract; keeps the valve from blowing out into the atrium

interventricular septum: separates the right and left ventricles

aorta:The aorta (/eɪˈɔrtə/) is the main artery in the human body, originating from the left ventricle of the heart and extending down to theabdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.^[1]

pulmonary trunk:The pulmonary artery carries deoxygenated blood from the heart to the lungs. It is one of the only arteries (other than the umbilical arteries in the fetus) that carry deoxygenated blood. The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.

Left atrium:The left atrium is one of four chambers in the human heart. It receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve.

atrioventricular canal:

left atrioventricular valve: lets blood flow from the atrium, down the left AC, and into the left ventricle

aortic semilunar valve: separates the aorta and pulmonary trunk left ventricle: empties into the aorta
