How many veins go in and out of your heart?!
Question: Veins and capillaries carry blood to the heart and there are hundreds of thousands of them and there are 4 main arteries carrying blood away.
Answers: Veins and capillaries carry blood to the heart and there are hundreds of thousands of them and there are 4 main arteries carrying blood away.
Four big ones.The heart has four chambers. The upper two are the right and left atria. The lower two are the right and left ventricles. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction.
What are the four heart valves?
The tricuspid valve is between the right atrium and right ventricle.
The pulmonary or pulmonic valve is between the right ventricle and the pulmonary artery.
The mitral valve is between the left atrium and left ventricle.
The aortic valve is between the left ventricle and the aorta.
Each valve has a set of flaps (also called leaflets or cusps). When working properly, the heart valves open and close fully.
Heart valves don't always work as they should. A person can be born with an abnormal heart valve, a type of congenital heart defect. Also, a valve can become damaged by:
infections such as infective endocarditis
rheumatic fever
changes in valve structure in the elderly
Veins only carry blood TO the heart, not away from.
The veins of the heart are left innominate vein, superior and inferior vena cava, left and right pulmonary veins, and cardiac vein.
the arteries carry blood away
Veins only cary blood into the heart.
The Great Cardiac Vein, beginning at the apex of the heart.
The Superior Vena Cava comes in from the top
The Inferior Vena Cava comes in from the bottom
The Left and Right Pulmonary Vein (two from each direction) but all enter into the left atrium (so considered one that comes into the heart)
So there are four.
