What is the circulation of a red blood cell in the human body?

Answer 1

Right atrium through the tricuspid valve to the right ventricle, through the pulmonary semilunar valve to the pulmonary trunk, to the lungs, to the capillary beds of the lungs, to the pulmonary vein, to the left atrium of the heart, through the mitral valve to the left ventricle, through the aortic semilunar valve to the aorta, to the systemic arteries, to the capillary beds of the tissues, to the systemic veins, to the superior vena cava, inferior vena cava, and coronary sinus entering the right atrium of the heart.

Right atrium through the tricuspid valve

to the RIGHT VENTRICLE through the PULMONARY SEMILUNAR valve

to the pulmonary trunk

to the LUNGS

to the capillary beds of the lungs

to the PULMONARY VEINS

to the LEFT ATRIUM of the heart through the BICUSPID (MITRAL) valve

to the LEFT VENTRICLE through the AORTIC SEMILUNAR valve

to the AORTA

to the systemic arteries

to the CAPILLARY BEDS of the tissues

to the systemic veins

to the SUPERIOR AND INFERIOR VENA CAVA

and CORONARY SINUS entering the right atrium of the heart
