What would connective tissues composition be?

Answer 1

Connective tissues are made up of cells and extracellular matrix. Examples: Bone tissue consists of osteocytes in an extracellular matrix of mineral deposits; blood consists of blood cells (primarily erythrocytes) surrounded by plasma (mostly water with dissolved proteins, glucose, mineral ions, hormones, carbon dioxide).

Connective tissue is a type of animal tissue that connects, supports, or separates other tissues and organs throughout the body.

Answer 2

Blood, cartilage, and bone are usually considered connective tissue, but because they differ so substantially from the other tissues in this class, the phrase "connective tissue proper" is commonly used to exclude those three. There is also variation in the classification of embryonic connective tissues; on this page they will be treated as a third and separate category.

Collagen is the main protein of connective tissue in animals and the most abundant protein in mammals, making up about 25% of the total protein content.

Areolar (or loose) connective tissue holds organs and epithelia in place, and has a variety of proteinaceous fibres, including collagen and elastin.

Dense connective tissue (or, less commonly, fibrous connective tissue) forms ligaments and tendons. Its densely packed collagen fibers have great tensile strength.

Blood functions in transport. Its extracellular matrix is blood plasma, which transports dissolved nutrients, hormones, and carbon dioxide in the form of bicarbonate. The main cellular component is red blood cells.

Bone makes up virtually the entire skeleton in adult vertebrates.

Cartilage makes up virtually the entire skeleton in chondrichthyes. In most other vertebrates, it is found primarily in joints, where it provides cushioning. The extracellular matrix of cartilage is composed primarily of collagen.

Adipose tissue contains adipocytes, used for cushioning, thermal insulation, lubrication (primarily in the pericardium) and energy storage. [fat]

Reticular connective tissue is a network of reticular fibres (fine collagen, type III) that form a soft skeleton to support the lymphoid organs (lymph nodes, bone marrow, and spleen.)

Answer 3

Connective tissues are predominantly made up of extracellular matrix, which consists of fibers (collagen, elastin) and ground substance (proteoglycans, glycoproteins). The cells found in connective tissues include fibroblasts, adipocytes, macrophages, and mast cells. These tissues provide structural support, insulation, protection, and transportation of nutrients.
