It is situated on the sternocostal surface of the heart, close to its left margin. –is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium). It delivers less-oxygenated blood to the right atrium, as do the superior and inferior vena cavae.
What is the function of the great cardiac vein?
Function: This cardiac vein returns deoxygenated blood (metabolic waste products) from the anterior surfaces of the left ventricle. Other Nomenclature: The section of the great cardiac vein that courses anteriorly in between the left and right ventricle is also known as the anterior interventricular vein.
What is the function of coronary veins quizlet?
Function of the coronary arteries is to deliver oxygenated blood to the myocardium.
What veins drain into the great cardiac vein quizlet?
Great cardiac vein drains what area? Anterior portions of the right and left ventricles. Middle cardiac vein DESCRIPTION: Located in the posterior interventricular sulcus, parallel to the posterior interventricular artery.
Which coronary artery provides blood to the left atrium and left ventricle quizlet?
Which coronary blood vessel delivers oxygenated blood to the walls of the left atrium and left ventricle? The circumflex artery delivers oxygenated blood to the left atrium and left ventricle.
What is the main function of small cardiac vein?
Function. The small cardiac vein receives blood from the posterior portion of the right atrium and ventricle.
Where does the great cardiac vein lead to?
The great cardiac vein then drains into the left end (origin) of the coronary sinus, at the same end as the oblique vein of Marshall which together marks the origin of the coronary sinus.
What is the function of the coronary sinus?
The coronary sinus is the major venous tributary of the greater cardiac venous system; it is responsible for draining most of the deoxygenated blood leaving the myocardium.
What veins drain into the great cardiac 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.
Great cardiac vein.
|Drains from||Small venules of the apex of heart|
|Drainage area||External layer of the myocardium of the ventricles and left atrium|
What is the interventricular septum quizlet?
Interventricular septum. The ventricles of the heart are separated into left and right sides by the. Veins. blood vessels that carry blood back to the heart.
What does not drain into the cardiac sinus quizlet?
What cardiac veins do not drain into the coronary sinus? Anterior cardiac veins and the Thebesian veins.
Which heart chamber that coronary veins drain blood into quizlet?
Where does the coronary sinus vein drain? The great cardiac vein, small and middle cardiac veins drain into the coronary sinus. The coronary sinus empties into the right atrium.
What is the function of the pulmonary artery quizlet?
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.
Which vessels carry blood away from the heart quizlet?
The blood vessels that carry blood away from the heart are called arteries.
What is the term used for blockage of blood flow?
This disease process is called atherosclerosis. When blockages develop in the coronary arteries, the restricted blood flow results in a lack of oxygen to the heart muscle. This condition is known as coronary artery disease.
Is the circumflex artery a coronary artery?
The circumflex artery (Cx) is one of the two major coronary arteries that arise from the bifurcation of the left main coronary artery (the other branch being the left anterior descending (LAD) artery).
