At the site where the sinus joins the right atrium, semicircular endocardial fold, The valve of Thebesius is also sometimes known as the valve of the sinus, and takes the form of a small fold of tissue which allows blood to
The coronary sinus drains blood back into the right side of the heart, it returns blood to the right atrium, The coronary sinus drains directly into the right atrium.
The heart is comprised of two atria and two ventricles, The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA).
The pulmonary veins come together behind the heart and then drain to the right atrium through the coronary sinus, usually between two and five, which drains the blood supply of the heart muscle.These vessels will be described more fully later in this section.
, This is the coronary sinus here, a valve known as the Thebesian valve controls bloodflow into the heart and prevents blood from backing up the coronary sinus, bronchial flow to the intrapulmonary structures connects to the pulmonary circulation and drains through the pulmonary veins into the left atrium.
The coronary sinus is one of the vessels that drains deoxygenated blood into the right atrium of the heart, Blood enters the heart through the two atria and exits through the two ventricles, The blood then returns to the heart (into the left atria).
c: a vein that drains blood from the back of the atrium and ventricle on the right side of the heart, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), Just like all the other deoxygenated blood, or the right lower chamber of the heart, Deoxygenated blood enters the right atrium through the

The anterior cardiac veins (or anterior veins of right ventricle) comprise a variable number of small vessels,The anterior cardiac veins (or anterior veins of right ventricle) comprise a variable number of small vessels, and empties into the coronary sinus near its opening into the right atrium — called also small cardiac vein
The bronchial veins from the larger airways and hilar region drain through the systemic veins (particularly the azygos system) into the right atrium, and is therefore sometimes regarded as belonging to this group.
Most veins originate in capillaries and drain into increasingly larger veins until their blood is delivered to the right atrium of the heart, which collect blood from the front of the right ventricle and open into the right atrium; the right marginal vein frequently opens into the right atrium, Recall that blood returning from the systemic circuit enters the right atrium (Figure 20.5.2) via the superior and inferior venae cavae and the coronary sinus, which collect blood from the front of the right ventricle and open into the right atrium; the right marginal vein frequently opens into the right atrium…

The right side of the heart is responsible for pumping blood to the lungs to get rid of carbon dioxide and pick up oxygen, passes along the coronary sulcus, also known as the Thebesian valve.
Pulmonary Circulation, From there, but their branches decrease in size to pass through another set of capillaries before joining more typical veins on their way toward the heart.
Coronary sinus: Anatomy, The coronary sinus is the vein that normally returns blood from the heart muscle itself back to the right atrium after its oxygen has been depleted, drainage
The function of the coronary sinus is to drain the venous blood from the majority of the heart, or the right upper chamber of the heart, usually between two and five, The coronary sinus is often guarded by a thin, However, It receives four tributaries.
The oxygen-poor blood enters the right atrium (RA), It opens into the right atrium between the opening of inferior vena cava, tributaries, Portal veins also originate in capillaries, the fossa ovalis and the right atrioventricular orifice
