What is the correct sequence that occurs during the process of blood flowing through the body beginning at the heart?
1) It travels through the mitral valves and into the left ventricle.
2) Blood passes through the tricuspid valve into the right ventricle.
3) Blood enters the pulmonary artery and lungs, where it receives oxygen.
4) It moves on through the pulmonic valve during ventricular contraction
5) The right atrium receives deoxygenated blood from the superior and inferior vena cava and the coronary sinus
6) It returns to the left atrium via the pulmonary veins
A) 2, 3, 4, 6, 1, 5
B) 4, 3, 6, 5, 1, 2
C) 5, 2, 4, 3, 6, 1
D) 6, 4, 2, 5, 3, 1

The correct sequence starts with deoxygenated blood entering the right atrium (5), then moving through the tricuspid valve into the right ventricle (2). During ventricular contraction, blood passes through the pulmonic valve (4) and enters the pulmonary artery to reach the lungs (3), where it gets oxygenated. It then returns to the left atrium via the pulmonary veins (6) and travels through the mitral valve into the left ventricle (1), completing the cycle.
