Which veins empty into the right atrium?
On the right side Oxygen-poor blood from all over your body enters your right atrium through two large veins, your inferior vena cava and superior vena cava.
Which vessels empty into the left atrium?
The pulmonary veins empty blood into the left atrium. From the left atrium, oxygenated blood enters the left ventricle, the aorta, and enters circulation in the arteries, arterioles and capillaries of the body.
How many vessels drain into the right atrium?
two vesselsThe inferior vena cava and coronary sinus are the only two vessels draining into the right atrium that have valvular mechanisms to prevent venous reflux.
Which vessel does not drain directly into the right atrium?
Answer and Explanation: The right atrium does not receive blood from the d) circumflex artery. The right atrium receives the deoxygenated blood from the systemic circuit via the superior and inferior vena cava which are the main collecting vessels of the venous system.
What veins drain the lungs?
Bronchial veins are small vessels that form a part of the venous drainage of the lungs. These vessels drain the larger pulmonary bronchi and the area of the lung close to the hilum. The bronchial veins can be divided into two systems; deep and superficial.
What is the function of middle cardiac vein?
Along with the great and small cardiac veins, the middle cardiac vein constitutes the greater cardiac venous system. The function of the middle cardiac vein is to drain the venous blood of the external layer of the myocardium.
Does anterior cardiac vein drain into coronary sinus?
The anterior cardiac veins do not drain into the coronary sinus but drain directly into the right atrium. Some small veins known as Thebesian veins drain directly into any of the four chambers of the heart.
What drains into superior vena cava?
The azygos vein is another vein that drains into the superior vena cava. This vein is unpaired. It runs along the right aspect of the thoracic vertebral column and enters into the thorax at the aortic hiatus of the diaphragm. The azygos vein forms from the joining of the right subcostal and ascending lumbar veins.

What is the name of the veins on the right ventricle?
Last reviewed: May 31, 2021. Reading time: 1 minute. Anterior cardiac veins ( Venae anteriores cordis) The anterior cardiac veins, also known as the anterior cardiac veins of right ventricle, are the small parallel veins found on the anterior surface of the right ventricle.
What is the function of the anterior cardiac veins?
The function of the anterior cardiac veins is to drain the upper anterior portion of the myocardium of the right ventricle. These veins empty directly into the right atrium, unlike the majority of the cardiac veins that empty into the coronary sinus.
Where are the 3-5 veins located?
The 3-5 anterior cardiac veins emerge on the anterior surface of the right ventricle. They course horizontally across the surface of the ventricle, located deep to the epicardial layer of the heart.
What is the cardiac vein?
The cardiac veins, in general, follow the distribution of the coronary artery system, running parallel and superficial to the coronary arteries and their branches. The great cardiac vein runs parallel but in opposite direction to the LAD in the anterior interventricular groove (see Fig. 50.3A ). The great cardiac vein continues its course in the left anterior AV groove along with the LCx artery (see Fig. 50.3A ). Throughout its course, the great cardiac vein receives its tributaries from the left ventricle and atrium. In the left posterior AV groove, the great cardiac vein becomes a larger venous structure known as the coronary sinus (see Fig. 50.3B ). The coronary sinus is about 3 to 5 mm in diameter and 2 to 5 cm in length and receives blood from most cardiac veins before it empties into the right atrium. One of its major tributaries is the middle cardiac vein, which runs superiorly in the posterior interventricular groove along the PDA (see Fig. 50.3B ). It empties into the coronary sinus at the crux of the heart. The lateral, posterolateral, and posterior cardiac veins of the left ventricle receive blood from their respective aspects of the left ventricle before emptying into the coronary sinus along the left AV groove. There are multiple anterior cardiac veins that receive blood from the right ventricle and drain into the small cardiac vein. The small cardiac vein runs along the right AV groove downward toward the crux, where it subsequently empties into the coronary sinus. Some of the anterior cardiac veins drain directly into the right atrium.
Which vein moves blood away from the anterior aspect of the heart and runs with the LAD?
The great cardiac vein: main tributary of the coronary sinus. Moves blood away from the anterior aspect of the heart and runs with the LAD.
What is the bandlike muscular structure that extends from the underside of the right atrial appendage to the?
46 A bandlike muscular structure extending from the underside of the right atrial appendage to the right ventricle was identified during dissection of the right AV groove ( Fig. 25-6 ). Internally, this structure corresponded to a pouch with a muscular wall that coursed through the epicardial fat and ultimately continued into the ventricular myocardium about 5 mm from the annular insertion of the tricuspid valve.
Where do epicardial APs occur?
Most reported epicardial APs occur adjacent to a CS diverticulum, the MCV, or the great cardiac vein.94 The atrial appendage-to-ventricular pathway is a recognized variant of AP connections that is characterized by an epicardial course connecting the atrial appendage and the ventricular base, most frequently on the right side. Delivery of RF energy at endocardial sites may be ineffective, resulting in failure of ablation or recurrence of pathway conduction.
Where do the anterior and posterior interventricular sulci continue?
Anterior and posterior interventricular sulci continue inferiorly to right of apex
Can cryoablation be done for ventricular tachycardia?
A few case series on cryoablation for ventricular tachycardia have been published. 165,166 Obel and coworkers reported three cases of left ventricular outflow tract tachycardia successfully ablated from the distal great cardiac vein.167 In a larger series, cryoablation with an 8-mm-tip catheter was attempted in 14 patients with highly symptomatic frequent monomorphic ventricular premature beats or nonsustained ventricular tachycardia originating within the right ventricular outflow tract. 168 Cryoablation resulted in complete success in all but one patient. Three patients reported slight pain arising from local pressure of the catheter on the right ventricular outflow tract with no pain related to delivery of cryothermal energy. All patients with acutely successful procedures remained arrhythmia free at 3 months of follow-up.
Which vein accompanies the AM?
The small cardiac vein: accompanies the AM. Removes blood from the right ventricle into the right atrium.
Where does the great cardiac vein come from?
The great cardiac vein emerges at the apex of the heart from the small venules that collect the venous blood of this cardiac region. It ascends along the anterior surface of the heart, passing through the anterior interventricular groove accompanied by the anterior interventricular artery. Once it reaches the bifurcation of the left coronary artery, it takes a sharp course to the left crossing into the left atrioventricular groove.
What is the function of the great cardiac vein?
The main function of the great cardiac vein is to contribute to the venous drainage of the external layer of the myocardium. This article will discuss the anatomy , course and function of the great cardiac vein.
Where does the heart's heart vein go?
The vein passes below the left auricle of the heart, emptying into the coronary sinus. Just prior to the opening into the coronary sinus, it is joined by the oblique vein of left atrium (of Marshall). Along its course, the great cardiac vein receives small tributaries from the myocardium of both ventricles and the left atrium. It also receives the venous blood from the left marginal vein.
What is the heart vein?
The great cardiac vein, also called the anterior interventricular vein, is a large blood vessel found on the anterior (sternocostal) surface of the heart. It is one of the veins that constitute the greater cardiac venous system, along with the coronary sinus, middle cardiac, small cardiac, anterior cardiac, anterior and posterior interventricular, right and left marginal, left posterior, ventricular septal veins, infundibular veins, veins of the atria, vein of Zuckerkandl, vein of Cruveilhier, and oblique vein of Marshall.
