7. Connective tissue supports and connects
organs and tissue
 Adipose type of connective tissue that stores fat cells
 Cartilage firm, flexible support of the embryonic skeleton
and part of the adult skeleton
 Tendons white bands of connective tissue attaching
skeletal muscle to bone
 Ligaments strong, flexible bands of connective tissue that
hold bones firmly together at the joints
