Blood Circulation

Anatomic Model Of The Blood Circulation Of The Chest Of An Adult Human Body, Face On. The Pulmonary Circulation Carries The Deoxygenated Blood, Collected From The Whole Body Through The Venous Network In Royal Blue, From The Heart To The Lungs, And Then Brings Back The Oxygenated Blood From The Lung Alveoli To The Heart, In Order That It Is Redistributed To All The Cells Of The Body Through The Arterial Network In Red. More Precisely, The Superior And Inferior Vena Cavas Wide Vertical Veins In Royal Blue Carry The Deoxygenated Blood To The Right Atrium Of The Heart. This Dark Blood Goes Through The Right Ventricle And Is Then Propeled To The Lungs Via The Pulmonary Trunk, Dividing In Right And Left Pulmonary Arteries And Then In Arterioles In Royal Blue. The Oxygenated Blood Is Next Sent Back From The Lung Alveoli To The Heart Through The Pulmonary Veinules And Veins In Red. The Heart Expels Then The Blood To The Whole Body Via The Arch Of Aorta In Red. Under The Diaphragm In White, The Abdominal Aorta And Its Numerous Branches In Red Irrigate All The Viscera: Particularly, The Splenic Artery For The Spleen In Plum, Located On The Left Lateral Abdominal Wall, The Common Hepatic Artery Dividing In The Proper Hepatic Artery For The Liver In Dark Red And In The Renal Arteries For The Kidneys In Incarnate. The Deoxygenated Blood Is Drained From The Kidneys By The Renal Veins In Royal Blue, Then Directed Towards The Heart Through The Inferior Vena Cava. The Venous Blood Coming From The Digestive Organs Follows A Particular Network Independent Of The Heart: The Portal System Of Veins. Indeed, The Blood Collected By Diverse Vessels Splenic Vein For The Spleen Empties Into The Portal Vein Thin Vessel Depicted In Royal Blue For Both Liver Lobes Which Carries It To The Liver, Where It Is Detoxified. The Processed Blood Flows Then Into The Hepatic Veins The One Of The Right Hepa (Photo By BSIP/UIG Via Getty Images)
