Which branches into arteries and then into smaller vessels?
Arteries and arterioles The arteries branch into smaller and smaller vessels, eventually becoming very small vessels called arterioles. Arteries and arterioles have muscular walls that can adjust their diameter to increase or decrease blood flow to a particular part of the body.
What divides into smaller arteries?
The aorta branches into arteries, which eventually branch into smaller arterioles. Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries.
What are the two branches of the heart?
The two main branches are the left coronary artery (LCA) and right coronary artery (RCA). The arteries can additionally be categorized based on the area of the heart for which they provide circulation.
What are the major branches off of the heart?
The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.
What are the two branches of the left coronary artery quizlet?
The left coronary artery branches from the left aortic sinus of the ascending aorta passing between the pulmonary trunk and the left auricle before entering the coronary sulcus. Posterior to the pulmonary trunk, the artery divides into its two terminal branches, the anterior interventricular and the circumflex.
Which is the smallest blood vessels?
Capillaries, the smallest blood vessels, connect arteries and veins.
What are the two main arteries in the heart?
The 2 main coronary arteries are: Left main coronary artery. This artery sends blood to the left side of the heart muscle. This includes the left ventricle and left atrium. It divides into these branches: Left anterior descending artery. This smaller artery branches off the left coronary artery.
Which is the smallest artery in the body?
Abdominal aorta: The abdominal aorta supplies blood to the lower portions of the body including the legs. Arteries make up only a portion of the blood vessels in the body. They further divide into arterioles and capillaries. Arterioles are the smallest arteries, and they connect directly to capillaries to form the capillary bed.
Which is the artery that supplies blood to the head and neck?
Brachiocephalic artery: This artery and its branches supply blood to the right side of the head and neck and the right arm. Left common carotid artery: This artery supplies blood to the left portions of the head and neck. Left and right coronary arteries: The coronary arteries supply blood to the muscles of the heart.
What are the different types of blood vessels?
Arteries are the blood vessels that carry blood away from the heart. The different types of arteries include: Elastic arteries: are also called conducting arteries that have a thick middle layer that stretches in response to each pulse. Muscular arteries: are medium-sized arteries that draw blood from elastic arteries.
