Blood Circulation in the Body:
- Pulmonary Circulation (Circulus Sanguid Minor):
○ Deoxygenated blood comes from the body into the right atrium through the superior and inferior vena cava.
○ Blood goes through the Tricuspid valve into the right ventricle
○ The right ventricle pumps blood through the pulmonary valve into the pulmonary artery
○ The pulmonary artery pumps blood into the lungs
- Circulus Sanguis major (Systemic Circulation):
○ Blood comes from the lungs into the left Atria
○ The left atria send blood through the bicuspid valve into the left ventricle.
○ The left ventricle sends blood through the Aortic Valve into the Aorta
○ Aorta sends blood to the body again

    Thanks to your video. Recently a member in my family had Atrial Fibrillation and LVF at 20 to 25pct. Within days of resuscitation, she had a fall and broke the head of the Femur, calling for a Total Hip Replacement Surgery. All of us kept our fingers crossed and her heart behaved nobly. I was going through various videos on the anatomy and electrical conduction of heart, but yours is the best, precise and presented in 3-D form. Quite happy with your video. I have immediately subscribed to your channel.
