Skeletal System, Osteon Questions and Answers Graded A+ How do osteons help bones resist pressure and weight? Osteons are arranged in a way that aligns with the direction of the forces placed on the bone, providing optimal strength. What structural feature of the osteon is responsible for its strength and resilience? The concentric lamellae, which form a dense, organized structure around the central canal. What is the primary function of the lacunae in osteons? Lacunae house the ...

Is energy required to move oxygen and carbon dioxide across membranes? correct answers No, it is done via passive diffusion from high partial pressure to low partial pressure. How do internal and external respiration differ? correct answers Internal: gas exchange between the blood and the tissues External: gas exchange between the environment and the blood What processes constitute respiration? correct answers Delivery of oxygen to tissues and removal of waste products; can be external (...
