What is the correct order of blood flow in the heart?
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
What are the structures leading to and from the heart?
The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary …
What are the parts of the heart in order?
The heart is made up of four chambers: two upper chambers known as the left atrium and right atrium and two lower chambers called the left and right ventricles. It is also made up of four valves: the tricuspid, pulmonary, mitral and aortic valves.
What are the 5 structures of the heart?
The heart is enclosed in a pericardial sac that is lined with the parietal layers of a serous membrane. The visceral layer of the serous membrane forms the epicardium….Chambers of the Heart
- Right atrium.
- Right ventricle.
- Left atrium.
- Left ventricle.
What is the correct pathway for the flow of blood through the heart starting at the vena cava?
The blood enters the heart from the body through the superior vena cava and the inferior vena cava. Then the blood enters the right atrium chamber of the heart. The blood then moves through the tricuspid valve (shown as two white flaps) into the right ventricle chamber of the heart.
What are the 13 parts of the heart in order?
Anatomy of the heart

- Right atrium and auricle. Right atrium. Right auricle.
- Interventricular septum and septal papillary muscles. Interventricular septum.
- Right ventricle and papillary muscles. Right ventricle.
- Left ventricle and papillary muscles. Left ventricle.
What is the correct order of blood flow from the superior vena cava?
Both the superior vena cava and inferior vena cava empty blood into the right atrium. Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs.
What are the 14 parts of the heart?
What are the 4 heart valves?
Roles of Your Four Heart Valves
- Tricuspid Valve. Has three leaflets or cusps.
- Pulmonary Valve (or Pulmonic Valve) (link opens in new window)
- Mitral Valve. Has two leaflets.
- Aortic Valve. Has three leaflets, unless it’s abnormal from birth, i.e., bicuspid aortic valve.
