Connective

Connective Tissue

Connective tissue is one of the four types of biological tissue that supports, connects, or separates different types of tissues and organs in the body. It is made up of cells, fibers, and extracellular matrix and is classified into two subtypes: soft and specialized connective tissues.

Types of Connective Tissue

Soft Connective Tissues

Soft connective tissues include areolar tissue, adipose tissue, and reticular connective tissue.

• Areolar Tissue: This is the most common type of connective tissue in the body. It holds organs in place and attaches epithelial tissue to other underlying tissues.

• Adipose Tissue: Also known as fat, this tissue stores energy in the form of fat globules. It also cushions and insulates the body.

• Reticular Connective Tissue: This tissue is found in the lymphatic system and bone marrow. It provides a supportive framework.

Specialized Connective Tissues

Specialized connective tissues include cartilage, bone, and blood.

• Cartilage: This is a flexible connective tissue found in many areas of the body including the joints, the rib cage, the ear, the nose, the throat, and between the bones of the spine and pelvis.

• Bone: This is a rigid connective tissue that makes up the skeleton of the body. It supports the body, protects the organs, provides levers for movement, stores calcium and other minerals, and houses the bone marrow where blood cells are formed.

• Blood: This is a fluid connective tissue that transports oxygen, nutrients, and other substances throughout the body. It also removes waste products.

Functions of Connective Tissue

Connective tissue has a variety of functions including:

• Providing support and structural framework for the body
• Storing energy
• Providing protection and insulation
• Transporting substances within the body

Diseases of Connective Tissue

There are many diseases that can affect connective tissue. These include rheumatoid arthritis, lupus, scleroderma, and Marfan syndrome. These diseases can cause a variety of symptoms and can affect different parts of the body.
