Answer 1

Explanation:

Anatomical Parts

The coronary sinus opens into the atrium, between the orifice of the inferior vena cava and the atrioventricular opening. The opening of coronary sinus returns blood from the substance of the heart and is protected by a semicircular valve, the valve of the coronary sinus (valve of Thebesius).

Answer 2

Answer:

Thebasian valve

Between the inferior vena cava's orifice and the atrioventricular aperture, the coronary sinus enters the atrium. A semicircular valve, the valve of the coronary sinus, guards the opening of the coronary sinus, which receives blood returning from the heart's tissue (valve of Thebesius).

Explanation:

• The embryonic sinoatrial valve's caudal remnant is the thebesian valve.
• The mouth of the coronary sinus in the right atrium typically has a semicircular membrane fold. It is medial to the inferior vena cava opening and located on the inferior posterior surface of the heart.
• Although its function in healthy physiology is unknown, some specialists think that it might stop blood from regurgitating into the sinus as the atrium contracts.
• Sadly, the practical practice has shown that the valve may present challenges when cannulating the coronary sinus during cardiac resynchronization therapy (CRT). Studies on the Thebesian valve's anatomy may therefore have useful applications.
