Chapter 5, Problem 3CT
Summary Introduction
To explain: What happens to an older person’s bone without the larger amount of calcium.
Introduction: The compact bone tissue forms the circular layers around the small central canals. The circular layers are called osteon. Inside osteon, the small channels are connected with each other by serving channels for blood vessels and nerves that transport substances for osteocytes.
