What valve prevents the backflow of blood from the right ventricle into the right atrium?
The valve that prevents the backflow of blood from the right ventricle into the right atrium is called the tricuspid valve.
Narrowing of the valve between the right atrium and right ventricle is called?
Narrowing of the valve between the right atrium and right ventricle is called tricuspid stenosis. This condition can lead to decreased blood flow from the right atrium to the right ventricle, causing symptoms such as fatigue, shortness of breath, and fluid retention. Treatment may involve medications or surgical intervention to repair or replace the affected valve.

What vessel carries oxygen-rich blood into the left atrium?
The Superior Vena Cava also known as the anterior Vena Cava.
What is the blood pressure within the right atrium called?
The blood pressure within the right atrium is called central venous pressure (CVP). It is a measure of the pressure in the large veins close to the heart and reflects the amount of blood returning to the heart.
Ridges in anterior wall of right atrium are called?
Pectinate muscles
When blood enters the left atrium its muscular walls are?
strong then the right atrium but not as strong as the left ventricle because the left atrium deals with a higher pressure in comparison to the right atrium. The walls of the posterior left atrium are smooth, this part receives the 4 pulmonary veins The wall of the anterior left atrium contain musculi pectinati, small ridges in the wall Unlike in the right atrium there is no definitive division between the two
In what chamber of the heart do the superior and inferior vena cava open?
Anterior and posterior vena cavae are two collecting blood vessels,which open into right atrium of heart.They collect de-oxygenated blood from all the parts of the body.
What do you call the top portion of the heart?

What chamber of the heart lies most anterior?
Right Ventricle. The most posterior is the Left Atrium
The upper chambers of the heart are?
The two upper chambers are called the atria. A single atria is an atrium.
What are the top parts of the heart called?
right atrium and left atrium
What are the four chambers of the heart are called?
The four chambers are; Left atrium Right atrium Left Ventricle Right Ventricle The two upper chambers are called atria (singular: atrium) and the two lower chambers are called ventricles. There are four chambers of the heart - the right atrium, left atrium, right ventricle and left ventricle.
What are the inferior chambers of the heart called?
the ventricles
What are the upper chambers of the mammalian heart called?
the upper chambers of the heart are called the atria. (or atrium singular)
Name the two veins that cross over the superior part of the right coronary artery into the anterior surface of the right ventricle?
The two veins that cross over the superior part of the right coronary artery unto the anterior surface of the right ventricle are the anterior cardiac veins. The anterior cardiac veins are two or three small veins in the anterior wall of the right ventricle opening directly into the right atrium independently of the coronary sinus.
What are the 4 major veins of the heart called?
Right ventricle, left ventricle, right atrium, left atrium.
