Loose Connective Tissue

It also known as areolar tissue, is a cellular connective tissue with thin and relatively sparse collagen fibers.

Fills spaces outside many cells

Papillary layer of dermis, hypodermis, Surrounds lymph and blood vessels, below mesothelium and mucous membranes

Well vascularized

Abundant ground substance and tissue fluid

Fibroblasts/fibrocytes & macrophages common

Loosely woven collagen type I&III and elastic fibers

Loose Connective Tissue in the Intestine

Dense Regular Collagenous Connective Tissue

It is a type of connective tissue that is characterized by a high degree of organization. 

Collagen bundles have parallel orientation

Resists tensile forces

Tendons join muscle to bone

surrounded by loose connective tissue with ground substance for low friction

Ligaments connect bones together

Adipose Tissue

Adipose tissue, commonly known as fat tissue, is a type of connective tissue that plays several important roles in the body.

Types of Adipocytes:

White Adipocytes: The most abundant type in the human body. They have a single large lipid droplet and few cellular organelles.

Brown Adipocytes: Metabolically active cells with multiple lipid droplets and a high concentration of mitochondria (which generate heat).
