Explanation:
Vascular supply and circulation
In a typical long bone, blood is supplied by three separate systems: a nutrient artery, periosteal vessels, and epiphyseal vessels. The diaphysis and metaphysis are nourished primarily by the nutrient artery, which passes through the cortex into the medullary cavity and then ramifies outward through haversian and Volkmann canals to supply the cortex. Extensive vessels in the periosteum, the membrane surrounding the bone, supply the superficial layers of the cortex and connect with the nutrient-artery system. In the event of obstruction of the nutrient artery, periosteal vessels are capable of meeting the needs of both systems. The epiphyses are supplied by a separate system that consists of a ring of arteries entering the bone along a circular band between the growth plate and the joint capsule. In the adult these vessels become connected to the other two systems at the metaphyseal-epiphyseal junction, but while the growth plate is open there is no such connection, and the epiphyseal vessels are the sole source of nutrition for the growing cartilage; therefore they are essential for skeletal growth.
Answer:
Bone has a rich vascular supply, receiving 10-20% of the cardiac output. The blood supply varies with different types of bones, but blood vessels are especially rich in areas that contain red bone marrow. ... In growing bones, these arteries are separated by the epiphyseal cartilaginous plates.
