What are some arteries and veins?
Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart. Deep veins, located in the center of the leg near the leg bones, are enclosed by muscle. The iliac, femoral, popliteal and tibial (calf) veins are the deep veins in the legs.
What are the 5 veins?
These include the great cardiac vein, the middle cardiac vein, the small cardiac vein, the smallest cardiac veins, and the anterior cardiac veins. Coronary veins carry blood with a poor level of oxygen, from the myocardium to the right atrium.
What are the main arteries?
The 2 main coronary arteries are the left main and right coronary arteries.
- Left main coronary artery (LMCA). The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium).
- Right coronary artery (RCA).
What are the 3 parts of arteries and veins?
tunica intima: The innermost layer of a blood vessel. tunica externa: The outermost layer of a blood vessel. capillary: Any of the small blood vessels that connect arteries to veins. tunica media: The middle layer of a blood vessel.
How many types of veins are there?
There are four types of veins: Deep veins are located within muscle tissue. They have a corresponding artery nearby. Superficial veins are closer to the skin’s surface.
Where are the major arteries in your legs?
One travels down each leg and branches into internal and external iliac arteries, which supply blood to other branches, including the femoral artery. The femoral artery, the major artery in the thigh, continues to branch into other smaller arteries as blood travels all the way down to the tips of the toes.
What are the 4 types of veins?
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.
What is the biggest artery in the body?
Aorta Anatomy The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What are the 4 differences between arteries and veins?
Arteries carry blood away from the heart to the tissues of the body. Veins carry blood from the tissues of the body back to the heart. Arteries carry oxygenated blood expect pulmonary artery. Veins carry deoxygenated blood except pulmonary vein.
What is the smallest vein in the body?
Capillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
What are the names of the arteries in the human body?
Ascending aorta Left coronary artery Ascending aorta Left coronary artery LAD Left coronary artery Right coronary artery Right coronary artery Circumflex a Aortic arch Brachiocephalic a
What are the three arteries that supply the foot?
These three arteries supply the the leg. The foot is supplied by the dorsalis pedis artery (a continuation of the anterior tibial artery) and the posterior tibial artery. A vein is defined as a vessel that conducts blood from the periphery to the heart. All veins carry deoxygenated blood–except for the pulmonary vein.
What are the different types of blood veins?
What Are The Types Of Veins? 1 Pulmonary Veins. Pulmonary veins are a type of large-sized vein in the body that serves as the channel where newly oxygenated blood from the lungs moves into the heart before 2 Systemic Veins. 3 Superficial Veins. 4 Deep Veins. 5 Connecting Veins. …
Are there any valves in arteries or veins?
There are no valves in the artery vessels. There are valves in the veins allowing blood to flow in the upward direction. Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis. Veins are less susceptible to the diseases and few include diseases like varicose veins.
What are the names of the arteries?
In general, three types of arteries are found in the body: (1) Elastic Arteries, (2) Muscular Arteries, and (3) Arterioles. All three types are composed of three coats or tunics: (1) tunica intima (inner most), (2) tunica media (middle), and (3) adventitia (outer most).
What are the major arteries?
Major arteries. By definition, an artery is a vessel that conducts blood from the heart to the periphery. All arteries carry oxygenated blood–except for the pulmonary artery. The largest artery in the body is the aorta and it is divided into four parts: ascending aorta, aortic arch, thoracic aorta, and abdominal aorta.
What are the main arteries in the human body?
According to medical science, the main artery in the body is the aorta. It is connected to the left ventricle of the heart.
What are the major veins in the human body?
The largest veins in the human body are the venae cavae. These are two large veins which enter the right atrium of the heart from above and below. The superior vena cava carries blood from the arms and head to the right atrium of the heart, while the inferior vena cava carries blood from the legs and abdomen to the heart.
