Why are blood and bone called connective tissue?
Answers
Answer:
Blood is considered a connective tissue for two basic reasons: (1) embryologically, it has the same origin (mesodermal) as do the other connective tissue types and (2) blood connects the body systems together bringing the needed oxygen, nutrients, hormones and other signaling molecules, and removing the wastes.
If blood is a fluid connective tissue, bones are the hard connective tissue. Bones give support and framework to the body. They protect the internal organs and the muscle tissue attached to the bones helps in movement. The bone tissue is strong and non-flexible. The cells are embedded inside a hard matrix, which is made up of proteins, calcium and phosphorous.
