Q

What are the fibrous components of CT?

A

Collagen fibers, reticular fibers, and elastic fibers

17
Q

What makes up the ECM of CT?

A

Fibrous component and ground substance

18
Q

What is ground substance?

A

It’s a semi-fluid gel composed of carbs and proteins, water or tissue fluids, and ions

19
Q

In general, cells of CT are suspended in the ECM. What is the exception?

A

Blood! Cells are suspended in fluid (plasma) rather than ECM
