The cardiovascular system in 3D
The cardiovascular system is made up of the heart and the blood vessels: arteries, veins and capillaries. Blood pumped by the heart travels through the pulmonary circulation to the lungs and the systemic circulation to the rest of the body before returning to the heart, carrying oxygen and nutrients and collecting carbon dioxide and waste. In BAHI BODY you can view the heart’s four chambers and four valves, the aorta and the pulmonary trunk, the venae cavae and the great arteries of the neck and arms.
The path of blood through the heart
- Right atrium
- Tricuspid valve
- Right ventricle
- Pulmonary valve
- Pulmonary trunk
- Lungs · airways
- Left atrium
- Mitral valve
- Left ventricle
- Aortic valve
- Aorta
Organs
- Heart: The heart is a muscular organ in the middle of the chest, slightly to the left, between the lungs. With two atria, two ventricles and four valves it pumps blood to the lungs and the rest of the body.
Parts
- Right atrium: The chamber that first receives blood returning from the body.
- Right ventricle: It pumps blood from the right atrium out to the lungs.
- Pulmonary valve: The valve between the right ventricle and the pulmonary artery.
- Pulmonary trunk: The artery taking blood from the right ventricle to both lungs.
- Left atrium: The chamber that receives oxygen-rich blood from the lungs.
- Left ventricle: It pumps blood out to the whole body and has the thickest wall.
- Mitral valve: Between the left atrium and ventricle, it keeps blood from flowing back.
- Tricuspid valve: Between the right atrium and ventricle, it keeps blood from flowing back.
- Aortic valve: The valve between the left ventricle and the aorta.
- Aorta: The largest artery, carrying blood from the left ventricle to the body.
- Superior vena cava: The large vein that returns blood from the upper body to the right atrium. It drains the head, neck, arms and upper chest, and is formed where the left and right brachiocephalic veins join.
- Inferior vena cava: The largest vein in the body. It returns blood from the legs, pelvis and abdomen to the right atrium, running up the right side of the spine and through the diaphragm to reach the heart.
- Brachiocephalic trunk: The first branch of the aortic arch, found on the right side only. It divides into the right common carotid artery and the right subclavian artery.
- Brachiocephalic veins: Paired veins, one on each side at the base of the neck, each formed where the internal jugular and subclavian veins meet. The two join to form the superior vena cava.
- Common carotid arteries: The arteries supplying the head and neck, running up each side of the neck. The right one branches from the brachiocephalic trunk and the left straight from the aortic arch; each divides into the internal and external carotid arteries at the level of the upper border of the thyroid cartilage.
- Subclavian arteries: The arteries passing beneath the collarbones to supply the arms. The right one branches from the brachiocephalic trunk and the left straight from the aortic arch; each becomes the axillary artery past the outer edge of the first rib.
