What is the function of cardiac veins?
Function: The cardiac veins returns deoxygenated blood (containing metabolic waste products) from the myocardium to the right atrium. This blood then flows back to the lungs for reoxygenation and removal of carbon dioxide.
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.
- One answer you're likely to hear is that veins look blue because the blood inside actually is blue, because it's deoxygenated. If you wonder why you've never seen blue blood before, someone might tell you that's because when you bleed, the blood is oxygenated upon contact with air, and immediately turns red.

- The arteries are perceived as carrying oxygenated blood to the tissues, while veins carry deoxygenated blood back to the heart. However, in pulmonary circulation, the arteries carry deoxygenated blood from the heart to the lungs, and veins return blood from the lungs to the heart.
Veins are an important part of our circulatory system. They are responsible for returning deoxygenated blood back to the heart after arteries carry blood out. The vena cava is the largest vein in the body. Veins have much thinner walls than arteries.
- Capillaries- these are the sites of gas exchange between the tissues. 3. Veins- these return "oxygen poor" blood to the heart, except for the vein that carries blood from the lungs.
- Blood is always red, actually. Veins look blue because light has to penetrate the skin to illuminate them, blue and red light (being of different wavelengths) penetrate with different degrees of success. What makes it back to your eye is the blue light.
- What Three Things Help Push Blood Through Veins? The human circulatory system is a complex, closed network of blood vessels that deliver blood, oxygen and nutrients from the heart to the body -- and deoxygenated blood from the body back to the heart and lungs.
It also receives blood from the left marginal vein and the left posterior ventricular vein. It drains into the right atrium. The anterior cardiac veins do not drain into the coronary sinus but drain directly into the right atrium.
- The coronary sinus 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. It is present in all mammals, including humans.
- The smallest cardiac veins (or Thebesian veins) are minute valveless veins in the walls of all four heart chambers. The veins are sometimes accurately referred to as vessels, but they are frequently confused with a distinct set of artery connections eponymously referred to as the "vessels of Wearn".
- The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart.
