The Great Coronary Vein drains the muscles of the heart. It ascends the anterior interventricular sulcus (groove between the two ventricles) around the left coronary groove (groove between the left atrium and left ventricle) and into the coronary sinus on the right atrium of the heart.
What else can I help you with?
Where does the blood in the left atrium come from?
It comes from the 4 pulmonary veins that drain into the left atrium. they carry oxygenated blood that has come from the pulmonary circulation as well as the deoxygenated blood from the bronchial arteries.
How many mosquitoes would it take to completely drain a human of blood?
It would take about 1.2 million mosquitoes to completely drain a human of blood.
Where does the blood within the hepatic sinusoids drain into the vein?
The blood within the hepatic sinusoids drains into the hepatic vein.
What vessels carry blood to the right side of the heart?
superior vena cava(SVC) transports blood from body above the level of heart i.e.head, neck, face.. whereas inferior vena cava(IVC) transports blood from body below the level of heart i.e. the rest of the body.. SVC and IVC drain into the right atrium seperately.
What is found within the dural sinuses of the brain?
The dural sinuses are blood-filled channels located between the layers of the dura mater, the outermost membrane surrounding the brain. They collect blood from the brain and drain it back into the systemic circulation through the internal jugular vein. The sinuses contain venous blood, cerebrospinal fluid, and arachnoid granulations.
What structures drain deoxygenated blood into right atruim?
coronary sinus, ivc,svc
Which chamber does the coronary sinus drain into?
The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the myocardium of the heart. It is present in humans and other animals. It delivers deoxygenated blood to the Right atrium in conjunction with the superior and inferior vena cava.Wikipedia
Into which heart chamber does the coronary sinus drain?
The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the myocardium of the heart. It is present in humans and other animals. It delivers deoxygenated blood to the Right atrium in conjunction with the superior and inferior vena cava.Wikipedia
Does oxgyen rech the brain through the internal jagular vein?
No, the jugular veins drain deoxygenated blood from the head. The internal and external carotid arteries carry blood to the brain.
What do venuoles do?
venuoles branches off the vein and are also linked to the capillries/ these are vessels that drain the deoxygenated blood from the capillaries and takes them to the veins which returns it to the heart
What veins lead back to the heart from the lungs?
Pulmonary veins- which can be confusing because the blood in them is red and rich in oxygen since it just came from the lungs where it picked up O2. Vein drain to the heart. Arteries lead "A"way from the heart.
What is the main function of the venules?
Venules are small blood vessels that collect blood from capillaries and transport it to larger veins. Their main function is to drain deoxygenated blood from tissues and return it to the heart for oxygenation.
Venules drain these tiny beds of vessels?
Venules drain the capillary beds, which are the smallest blood vessels where the exchange of oxygen, nutrients, and waste products occurs between blood and tissues. After blood passes through the capillary network, it collects in venules, which then transport the deoxygenated blood back towards larger veins and ultimately to the heart. This process is essential for maintaining proper circulation and ensuring that tissues receive the necessary components for cellular function.
Which vein drain the walls of the heart?
The coronary sinus provides venous drainage to the myocardium. There is, however, direct drainage into the ventricles as well.
Which veins drain the walls of the heart?

What are cavities that filled with blood and help drain cerebrospinal fluid?
Cavities that are filled with blood and help drain cerebrospinal fluid in the brain are called the arachnoid granulations. These structures play a key role in maintaining the balance of cerebrospinal fluid in the central nervous system.
Where does the blood in the left atrium come from?
It comes from the 4 pulmonary veins that drain into the left atrium. they carry oxygenated blood that has come from the pulmonary circulation as well as the deoxygenated blood from the bronchial arteries.
