Question

Correctly route a RBC through the following structures starting in the right atrium.

1) Left atrium
4) Left ventricle
2) Right ventricle
5) Pulmonary artery
3) Pulmonary vein

a. 1, 2, 4, 5, 3
b. 2, 4, 5, 1, 3
c. 3, 4, 5, 1, 2
d. 2, 5, 3, 1, 4

Answer 1

The correct order for a red blood cell (RBC) to travel through the structures starting in the right atrium is option c. 3, 4, 5, 1, 2. The RBC would then continue its circulation through the rest of the body.

Step-by-step explanation:

The correct order for a red blood cell (RBC) to travel through the structures starting in the right atrium is option

c. 3, 4, 5, 1, 2

. This means that the correct order is Right atrium, Right ventricle, Pulmonary artery, Left atrium, Left ventricle. The RBC would then continue its circulation through the rest of the body.

The proper sequence for a red blood cell traveling from the right atrium is: right ventricle, pulmonary artery, pulmonary vein, left atrium, and then left ventricle, which corresponds to answer choice (d) 2, 5, 3, 1, 4.

To correctly route a red blood cell (RBC) through the heart starting from the right atrium, the sequence through which blood travels is as follows:

1. Right ventricle
2. Pulmonary artery
3. Pulmonary vein
4. Left atrium
5. Left ventricle

Therefore, the correct answer to the student's question is (d) 2, 5, 3, 1, 4.

After leaving the right atrium, the RBC enters the right ventricle. It is then pumped into the pulmonary artery. Following gas exchange in the lungs, the oxygenated RBC travels via the pulmonary veins to the left atrium. The final steps include passing into the left ventricle from where it is distributed to the rest of the body.
