Compact (dense) tissue is characterized by a tightly packed structure, providing strength and support to bones. It forms the outer layer of bones and is essential for weight-bearing and protection. Cancellous (spongy) tissue, on the other hand, has a porous, lattice-like structure that reduces bone weight while maintaining strength. It is typically found at the ends of long bones and within the interior of others, playing a key role in producing blood cells and storing marrow.
