Loose connective tissue is found through-out  the organism and has a fundamental  role in the nutrition of all tissues because it allows blood vessels to pass through it.
The tissue is made of a mixture of collagen, elastic and reticulin fibres.This can be seen in the liver substance and in the artery wall itself; here the circular muscle is held in place by a protective sheath of loose areolar tissue.

Connective tissue (C.T.) is the second of the four primary types of tissue in the body.
The ground substance of the connective tissue, which would occupy the space between the fibers and cells, is pale staining, and much of it is lost during most histological preparations.
These tissues are characterized by an overwhelming preponderance of the fibrous component of the tissue, with a correspondingly smaller volume of ground substance, tissue fluid and cells.

Connective tissue may be distinguished as either loose or dense, depending on the proportion of fibers.
Dense elastic connective tissue is found wherever the elasticity of elastin is of paramount importance, as in the ligamentum flavum (flavum refers to the yellow color conferred by the elastin) and the aorta.
The major determinant of the mechanical properties of most connective tissue is the extracellular matrix which is secreted by the cells within it (fibroblasts in ordinary connective tissue, osteoblasts and chondroblasts in bone and cartilage respectively).

 3. Connective Tissue
One generalization is that all of the cells of connective tissues derive from embryonic mesenchyme; thus, they are part of an extended family of cells with at least some common characteristics.
In fact, loose connective tissue often shows less shrinkage artifact than does dense because the larger number of interlaced fibers forms a felt-work that shrinks as a whole instead of allowing individual bundles of fibers to pull away from each other individually to form internal gaps.
Sometimes it is the vasculature or looseness of the tissue or the presence of glands which highlights the distinctiveness of the lamina propria.

 Connective Tissue
This is a specific type of extracellular matrix found as a sheet separating connective tissue from other tissue types, such as nerve, muscle, or blood vessel endothelium.
In tissue sections this space appears rather empty and unordered, but it is actually filled with a complex, regulated, and variously specialized network of interconnected glycoproteins and polysaccharides, which are not well preserved or stained by most standard histochemical procedures.
These include both long-term tissue residents, such as fibroblasts and adipose cells, and transient migratory residents, such as plasma cells, macrophages, and eosinophils, which move back and forth between tissue space and blood or lymph.

This type of dense regular connective tissue is found in the tendon, which connects muscles to bones or cartilage (Tendon 1).
Since bony tissue has no flexibility, the connective tissue must provide it and therefore elastic fibers are now found in the matrix; collagen is also present to provide tensile strength (Ligament 1).

 Frequently Asked Questions
In most of these cases, the patient is said to have an “undifferentiated connective tissue disease.” Other than watching the patient closely for signs of another disorder, the treatment is virtually the same as for primary Raynaud’s.
As a true genetic factor has not been clinically proven, it is uncertain as to whether or not family connections are based on increased awareness of the condition among relatives or true heredity.
Rheumatologists are the most knowledgeable specialists about Raynaud’s because they regularly treat people with the connective tissue diseases most closely associated with the condition (such as lupus, scleroderma and rheumatoid arthritis).
