Connective Tissue Bone, shown in Figure 8, has calcium salts in the matrix, giving it greater rigidity and strength. Bone also serves as a reservoir (or sink) for calcium.

Lacunae are commonly referred to as Haversian canals . Spongy bone occurs at the ends of bones and has bony bars and plates separated by irregular spaces. The solid portions of spongy bone pick up stress.

Unformatted text preview: cells ( erythrocytes ) carry oxygen. White blood cells ( leukocytes ) function in the immune system. Plasma transports dissolved glucose, wastes, carbon dioxide and hormones, as well as regulating the water balance for the blood cells. Platelets are cell fragments that function in blood clotting. Muscle Tissue Muscle tissue facilitates movement of the animal by contraction of individual muscle cells (referred to as muscle fibers ). Three types of muscle fibers occur in animals (the only taxonomic kingdom to have muscle cells): skeletal (striated) smooth cardiac...
