Final answer:
Connective tissue is a key component of bone, ligaments, and blood, aiding in support, protection, and integration of various body parts.
Step-by-step explanation:
The tissue that is a major component of bone, ligaments, and blood is connective tissue. This category of tissue serves the function of binding the cells and organs of the body together, providing support, protection, and integration for all parts of the body. Connective tissue encompasses a variety of tissue types, including bone tissue, blood, cartilage, adipose, and ligaments.
Bone tissue, particularly, is a hard, dense connective tissue that makes up the skeletal system. It comprises specialized cells, mineral salts, and collagen fibers. Such connective tissue is essential for maintaining the structure and strength of bones. In the context of ligaments, they are made up mostly of long, stringy collagen fibers which are also a component of connective tissue. Furthermore, blood is classified as a connective tissue due to its function in transporting nutrients and waste products throughout the body and it constitutes cells and plasma.
