Full Answer
What is the first type of loose connective tissue?
The first type of loose connective tissue is adipose tissue. In general, adipose tissue is fat tissue. There are two types of adipose tissue, brown adipose tissue, and white adipose tissue. Brown adipose tissue is found in the body during the fetal stages and infancy. It is brown in color, hence the name.
Which type of connective tissue is non-vascular?
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.

What is the role of adipose tissue?
Its main role is to store energy in the form of lipids, although it also cushions and insulates the body. Far from being hormonally inert, adipose tissue has, in recent years, been recognized as a major endocrine organ, as it produces hormones such as leptin, estrogen, resistin, and cytokines (especially TNFα ).
Which cytokines are released by perivascular adipose tissue?
Adipose tissues also secrete a type of cytokines (cell-to-cell signalling proteins) called adipok ines (adipose cytokines), which play a role in obesity-associated complications.
