Answered step-by-step
The main blood vessels that carry blood to and from the heart, lungs, liver, and kidneys are as follows:
To and From the Heart
- Aorta: The main artery that carries oxygenated blood from the left ventricle to the rest of the body.
- Vena Cava: Comprises two large veins:
- Superior Vena Cava: Carries deoxygenated blood from the upper body (head, neck, arms) to the right atrium.
- Inferior Vena Cava: Carries deoxygenated blood from the lower body (abdomen, legs) to the right atrium.
To and From the Lungs
- Pulmonary Artery: Carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
- Pulmonary Vein: Transports oxygenated blood from the lungs back to the left atrium.
To and From the Liver
- Hepatic Artery: Supplies oxygen-rich blood from the aorta to the liver.
- Hepatic Vein: Carries deoxygenated blood away from the liver back to the inferior vena cava.
- Hepatic Portal Vein: Transports nutrient-rich blood from the gastrointestinal tract and spleen to the liver for processing.
To and From the Kidneys
- Renal Artery: Supplies oxygenated blood from the aorta to each kidney.
- Renal Vein: Carries deoxygenated blood away from each kidney back to the inferior vena cava.
These vessels play crucial roles in ensuring that oxygenated blood reaches various organs while returning deoxygenated blood back to the heart for reoxygenation.
