Final answer:
Muscular arteries are known as distributing arteries as they distribute blood to organs and tissues, branching out from the aorta.
Step-by-step explanation:
The arteries that are known as distributing arteries because they distribute blood to the body organs and tissues are the muscular arteries. These arteries branch out from the aorta, the main artery of systemic circulation, which originates from the left ventricle and extends to the abdomen. The aorta distributes blood to the major arteries that supply the various parts of the body, including the carotid, brachial, thoracic, hepatic, renal, gastric, and iliac arteries. These, in turn, diverge into minor arteries and arterioles, reaching deeply into the muscles and organs. Muscular arteries contain more muscle tissue in their walls compared to the arteries close to the heart, which allows them to constrict and affect flow rates of blood as needed throughout the body.
