what is the correct sequence of events for blood flow through the heart?

From Internet:

Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) aorta –> 14) body.

The correct sequence of events for blood flow through the heart is as follows:

1. Deoxygenated blood enters the right atrium from the superior and inferior vena cava.
2. The right atrium contracts, and blood flows through the tricuspid valve into the right ventricle.
3. The right ventricle contracts, and blood is pumped through the pulmonary valve into the pulmonary artery.
4. The pulmonary artery carries deoxygenated blood to the lungs, where it picks up oxygen and releases carbon dioxide.
5. Oxygenated blood returns to the heart via the pulmonary veins and enters the left atrium.
6. The left atrium contracts, and blood flows through the mitral (bicuspid) valve into the left ventricle.
7. The left ventricle contracts, and blood is pumped through the aortic valve into the aorta.
8. The aorta distributes oxygenated blood to the rest of the body, delivering oxygen and nutrients to the tissues.
9. Deoxygenated blood returns to the heart, and the cycle begins again with step 1.

The correct sequence of events for blood flow through the heart is as follows:

1. Deoxygenated blood enters the right atrium from the body through the superior vena cava (bringing blood from the upper body) and the inferior vena cava (bringing blood from the lower body).

2. The right atrium contracts, and blood flows through the tricuspid valve into the right ventricle.

3. The right ventricle contracts, and blood is pushed through the pulmonary valve into the pulmonary artery.

4. The pulmonary artery carries deoxygenated blood to the lungs, where it picks up oxygen and gets rid of carbon dioxide through the process of respiration.

5. Oxygenated blood returns to the heart through the pulmonary veins and enters the left atrium.

6. The left atrium contracts, and blood flows through the mitral (bicuspid) valve into the left ventricle.

7. The left ventricle contracts, and blood is pumped through the aortic valve into the aorta, the largest artery in the body.

8. The aorta distributes oxygenated blood to the rest of the body, supplying tissues and organs with oxygen and nutrients.

To remember the sequence of events, you can use the mnemonic "Superior Vena Cava, Right atrium, Tricuspid valve, Right Ventricle, Pulmonary valve, Pulmonary artery, Lungs, Pulmonary veins, Left atrium, Mitral valve, Left Ventricle, Aortic valve, Aorta" or the acronym "SVA RAV TV RVP PVAL PAL LV MAV LVP AVL A" for short.
