Steps of Blood Flow in the Heart
These flashcards break down the process of blood circulation through the heart into simple, sequential steps. Ideal for students studying human anatomy and physiology, providing a clear understanding of how oxygenated and deoxygenated blood moves through the heart and lungs.
Step 1
Key Terms
Step 1
Deoxygenated blood flows from the inferior and superior vena cava into the right atrium.
Step 2
The right atrium contracts.
Step 3
The blood flows through the tricuspid valve into the right ventricle.
Step 4
The right ventricle contracts and blood flows from the pulmonary artery to the lungs.
Step 5
The deoxygenated blood picks up oxygen.
Step 6
Oxygenated blood flows along the pulmonary veins into the left atrium.
