Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers. Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide. Also present are various leukocytes (white blood cells) involved in immune response. Connective tissue (CT) is one of the four basic types of animal tissue, along with epithelial Examples of non-fibrous CT include adipose tissue and blood. Blood is a fluid connective tissue. It consists of a liquid matrix called the plasma, in which blood cells are present. So it can be said blood is an important lifeline. It travels all around the body in specialized blood vessels.

Loose connective tissue has much more ground substance and a relative lack of fibrous tissue, while the reverse is true of dense connective tissue.

Dense regular connective tissue, found in structures such as tendons and ligamentsis characterized by collagen fibers arranged in an orderly parallel fashion, giving it tensile strength in one direction.

Dense irregular connective tissue provides strength in multiple directions by its dense bundles of blood connective tissue arranged in all directions. Special connective tissue consists of reticular connective tissueadipose tissuecartilageboneand blood connective tissue.

Connective tissue

In the lungsblood acquires oxygen and releases carbon dioxide transported from the tissues. The kidneys remove excess water and blood connective tissue waste products. Nutrient substances derived from food reach the bloodstream after absorption by the gastrointestinal tract.

Glands of the endocrine system release their secretions into the blood, which transports these hormones to the tissues in which they exert their effects. Many substances are recycled through the blood; for example, iron released during the destruction of old red cells blood connective tissue conveyed by the plasma to sites of new red cell production where it is reused.

Blood | Definition, Composition, & Functions |

Each of the numerous components of the blood is kept within appropriate concentration limits by an effective regulatory mechanism. In many instances, feedback control systems are operative; thus, a declining level of blood sugar glucose leads to accelerated release of glucose into the blood so that a potentially hazardous depletion blood connective tissue glucose does not occur.

In a circuit through the cardiovascular system, red blood cells transport oxygen from the lungs to the body tissues and transport carbon dioxide from the body tissues to the lungs. Unicellular organisms, primitive multicellular animals, blood connective tissue the early embryos of higher forms of life lack a circulatory system.

Connective Tissue

Because of their small size, these organisms can absorb oxygen and nutrients blood connective tissue can discharge wastes directly into their surrounding medium by simple diffusion. Sponges and coelenterates e. In larger and more-complex animals, transport of adequate amounts of oxygen and other substances requires some type of blood circulation.

In most such animals the blood connective tissue passes through a respiratory exchange membranewhich lies in the gillslungs, or even the skin.

There the blood picks up oxygen and blood connective tissue of carbon dioxide. The cellular composition of blood varies from group to group in the animal kingdom. Most invertebrates have various large blood cells capable of amoeboid movement.

Some of these aid in transporting substances; other are capable of surrounding and digesting foreign particles or debris phagocytosis.

Compared with vertebrate blood, however, that of the invertebrates has relatively few cells. Among the vertebrates, there are several classes of amoeboid cells white blood cells, or leukocytes and cells that help stop bleeding plateletsor thrombocytes.

Oxygen requirements have played a major role in determining both the composition of blood and the architecture of the circulatory system. Collagen also blood connective tissue bone and cartilage. Elastic and reticular fibers are less abundant connective tissue proteins with a more limited distribution.

The ground substance may be liquid, as in blood; gelatinous, as in areolar tissue; rubbery, as in cartilage; or calcified and stony, as in bone.
