Vascular connective tissue is the tissue responsible for transport in the body of an animal. There are several types of connective tissue, such as adipose tissue, the lymphatic system, osseous tissue and bone marrow. Cartilage is a type of connective tissue that is non-vascular, because it doesn't transport anything.
The lymphatic system transports the fluid lymph to the heart. Blood circulates throughout the body, adipose tissue insulates the organs with protective fat and regulates body temperature, and osseous tissue is associated with bone and marrow. Cartilage exists between joints, bones and other sites in the body. It is distinguished from vascular connective tissue because it does not contain blood vessels.
