Jul 13, 2023 · The anterior cardiac veins are responsible for draining the sternocostal aspect of the right ventricle. Thebesian veins The smallest cardiac veins (venae cordis minimae) are a collection of small veins of the heart. Otherwise known as Thebesian veins or small cardiac veins, these vessels range from 0.5 – 2 mm in diameter. Although they are ...

Your veins make up an extensive network of blood vessels that wind their way through your entire body. Together, your veins and other blood vessels form a major part of your circulatory system. Your veins connect with venules and capillaries in many places. When mapped out in a drawing, your upper body circulatory system resembles the complex wires...
Many people think veins are blue because they look blue through our skin. But that’s just a trick that our eyes play on us. Your veins are actually full of dark red blood — darker than the blood in your arteries, which is cherry red. The blood in your veins is darker because it lacks oxygen. Your veins look blue because of the way light rays get ab...
Each vein is made of three layers of tissues and fibers: 1. The tunica adventitia (outer layer) gives structure and shape to your vein. 2. The tunica media (middle layer) contains smooth muscle cells that allow your vein to get wider or narrower as blood passes through. 3. Thetunica intima (inner layer) has a lining of smooth endothelial cells, all...
Your veins need an external force to help push your blood in the right direction. One such force is your own breathing. As your lungs expand and your diaphragm moves, they create a suction force that helps your veins push oxygen-poor blood toward your heart. Another force is your body’s muscle movement, especially in your legs. In fact, your leg mu...
Typically cardiac veins are free of atherosclerotic plaques. Importance in device delivery: Left heart pacing can be achieved by placing leads into the cardiac veins through the coronary sinus, which is located within the right atrium.

Veins: Unlike arteries, veins don’t have to carry highly pressurized blood, but they do have to carry large volumes of deoxygenated blood back to your heart. Thin, less elastic walls help them handle high volumes and low pressure. Most veins have valves that open and close. The valves control blood flow and keep your blood flowing in one ...
Sep 13, 2024 · Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins. Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart . Systemic veins return oxygen-depleted blood from the rest of the body to the right atrium of the heart.

Jan 8, 2024 · Small cardiac vein – located on the anterior surface of the heart, in a groove between the right atrium and right ventricle. It travels within this groove onto the posterior surface of the heart, where it empties into the coronary sinus. Middle cardiac vein (posterior interventricular vein) – begins at the apex of the heart and ascends in ...
