It is the nature of the matrix that defines the properties of these connective tissues. John D. Bancroft, Christopher Layton, in Bancroft's Theory and Practice of Histological Techniques (Seventh Edition), 2013 Dense connective tissue. They serve to bind together and support cells or groups of cells, and to provide a medium for the diffusion of ions and molecules and for the traffic of mobile cells (e.g., leukocytes) through various tissues and organs. a 30 minute presentation. Skin is also self-repairing after injury. understand enough basic anatomy to help you teach and learn from other students and teachers.

Collagen is a strong protein and is a main component of ligaments and tendon. NOTE: It also provides metabolic support by creating a hydrophilic environment that mediates the exchange of substances between the blood and tissue. It supports and protects the body, provides surface area for muscle attachment, helps body move, stores minerals and houses blood . Despite its . 30% start in the torso or abdomen.
