Final answer:
The flow of blood through the pulmonary circuit starts with the right atrium and ends in the left atrioventricular valve. The pathway includes the tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary veins, left atrium, and left atrioventricular valve.
Step-by-step explanation:
Flow of Blood Through the Pulmonary Circuit
- Right atrium
- Tricuspid valve
- Right ventricle
- Pulmonary valve
- Pulmonary artery
- Lungs
- Pulmonary veins
- Left atrium
- Left atrioventricular valve
The flow of blood through the pulmonary circuit starts with the right atrium receiving deoxygenated blood from the body. The blood then flows through the tricuspid valve into the right ventricle. From the right ventricle, the blood is pumped through the pulmonary valve and into the pulmonary artery. The pulmonary artery carries the blood to the lungs, where it exchanges carbon dioxide for oxygen. Oxygenated blood then returns to the heart through the pulmonary veins and enters the left atrium. Finally, the blood flows through the left atrioventricular valve and into the left ventricle.
