The valves permit the flow of blood in One Direction only and not in reverse direction, preventing the back flow of the blood.

HEART❤ HAS FOUR VALVES :

1⃣TRICUSPID VALVE: which guards the opening between the right auricle and the right ventricle.

2⃣BICUSPID VALVE: which guards the opening between the left auricle and the left ventricle.

3⃣AORTIC SEMILUNAR VALVES: located at the point of origin of aorta from the left ventricle and are three in number.

4⃣PULMONARY SEMILUNAR VALVES: Located at the opening of right ventricle into the the pulmonary artery and are three in number.

Answer 2

$\huge\underline\purple{\sf Answer}$

VALVES OF HEART ::

❇There are mainly four types of valves are present.

1.TRICUSPID VALVE

2. BICUSPID VALVE

3. AORTIC /SYSTEMIC SEMILUNARVALVE.

4. PULMONARY SEMILUNAR VALVE

TRICUSPID VALVE ::

➡This valve is present between right atrium and right ventricle.

➡This valve prevents back flow of the blood in reverse direction.

➡This valve allows blood to flow in one direction.

BICUSPID VALVE ::

➡This valve is present between left atrium and left ventricle.

➡It is also known as mitral valve.

➡ it mainly allows passage of oxygen rich blood.

SYSTEMIC S. VALVE ::

➡This valve guards the opening of aorta or systemic artery.

➡This is the largest artery.

➡This artery arises from the left ventricle.

PULMONARY S. VALVE ::

➡This valve guards the opening of pulmonary artery.

➡It arises from the right ventricle of the heart.
