Question

1. practice labeling heart structures below:

word bank: septum, pulmonary artery, right atrium, right ventricle, left atrium, left ventricle, pulmonary veins, aorta, tricuspid valve, bicuspid valve, superior vena cava, aortic valve
(image of heart structure with labels to fill)
the path of blood flow through a human heart. use directional arrow

Explanation:

Step1: Identify the structure next to the aorta

The structure adjacent to the aorta (already labeled) is the pulmonary artery. So the top - middle blank (next to aorta) should be labeled as "pulmonary artery".

Step2: Identify the structure connected to the left atrium (LA)

The structure connected to the left atrium (LA) is the pulmonary veins. So the blank connected to LA (the one above LA) should be labeled as "pulmonary veins".

Step3: Identify the valve in the right atrium - right ventricle (RA - RV) path

The valve between the right atrium (RA) and right ventricle (RV) is the tricuspid valve. So the blank connected to RA - RV path (the left - middle blank) should be labeled as "tricuspid valve".

Step4: Identify the valve in the left atrium - left ventricle (LA - LV) path

The valve between the left atrium (LA) and left ventricle (LV) is the bicuspid valve (mitral valve). So the blank connected to LA - LV path (the right - middle blank) should be labeled as "bicuspid valve".

Step5: Identify the structure separating the two ventricles

The structure separating the right ventricle (RV) and left ventricle (LV) is the septum. So the bottom - middle blank (between RV and LV) should be labeled as "septum".

Step6: Identify the structure connected to the right atrium (RA)

The structure connected to the right atrium (RA) is the superior vena cava (SVC is already labeled, and the other connection to RA is consistent with the word bank, but the SVC is labeled, and the right atrium's other connection is part of the vena cava system, but in the word bank, the superior vena cava is given, and we already labeled SVC. The right atrium is labeled RA, and the structure we need to label for the right atrium's valve is tricuspid (done in step3). For the septum, we labeled that. The aortic valve (AV) is labeled.

Answer:

• Top - middle blank: pulmonary artery
• Blank above LA: pulmonary veins
• Left - middle blank: tricuspid valve
• Right - middle blank: bicuspid valve
• Bottom - middle blank: septum
