Most types of connective tissue contain fibrous strands of the protein collagen that add strength to connective tissue. Some examples of connective tissue include the inner layers of skin, tendons, ligaments, cartilage, areolar, adipose bone and fat tissue. In addition to these more recognizable forms of connective tissue, blood is also considered a form of connective tissue.

• *Describe the 3 main types of cells and the 3 main types of fibers found in connective tissue? Reference Table 5.6.

6. Within days after a fracture, a “soft callus” of fibrocartilage forms. What fibers are found in this type of cartilage? Identify the cells required for fibrocartilaginous callus formation and list their functions.

4. Organ level- Organs are made up of different types of tissues. Organ is a discrete structure composed of at least two tissue types that performs a specific function for the body.

and connective tissue. Although an organ has a specific function, organs also function as part of

2. Describe and give at least one example of each of the functions of the integumentary system.

A.) Which serous membrane in Chloe’s abdomen most likely contains the greatest amount of adipose tissue?

The matrix of a tissue can be secreted by the connective tissues within the body. The functions of connective tissues are to transport materials around the body to give support to the weak areas to protect and support the body.

3. Describe the primary functions of each type of body tissue and give examples of each.

Connective tissue - Connective tissues holds and binds everything together which are found all around the body. This type of tissue is also called fibrous connective tissues as they are consisting of a lot of fibres eg. Collagen and Elastin.

The second type of tissue found in the body is connective tissue. They lie beneath the epithelial tissue helping to connect different part of the internal structure, the cells are more widely separated from each other then in epithelial tissue. The intercellular substance known as the matrix is found in considerably large amounts. Within the matrix there are usually fibres which may be a jelly like consistency or dense and rigid depending on the type, function and positioning of the tissue. Theses fibres form a supporting system for cells to attach to. The major functions of connective tissue are to transport materials, give structural support and protection. The types of connective tissue that will be explained are blood, bone, cartilage, bone, areolar tissue and adipose tissue.

Collagen is a fibrous protein which functions in the extracellular matrix and connective tissue. This protein strengthens and supports tissues in the body, such as bone, cartilage, skin, and tendons. Collagen 1 (alpha 1) is the most abundant type of collagen and is vastly distributed in connective tissue, except in hyaline cartilage. Type I collage is found throughout the body in the skin, tendon, vascular, organs, and it is responsible for strength and sturdiness. It is a triple helix formed by two copies of the alpha chain and one copy of the alpha 2 chain. Type II collagen is the main element of cartilage and it is formed by two or more collagens. Type III collagen makes up elastic tissues (skin, lungs, blood vessels). Type IV forms the
