Loose connective tissue skin and mucous membranes, it is more compact and sometimes difficult to distinguish from dense irregular connective tissue. Areolar connective tissues hold organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue. Organs that are rich in loose connective tissue(such as the eyelids) are usually sites that undergo oedema indicating renal failure or nephrotic syndrome. Thus periorbital swelling is one characteristic finding in severe renal disease Loose connective tissue Loose connective
Tissue culture growth of cells from a tissue from a multicellular organism "in vitro". These cells may be cells isolated from a donor organism, "primary cells", or an immortalised cell line. The cells are bathed in a culture medium, which contains essential nutrients and energy sources necessary for the cells' survival. The term tissue culture is often used interchangeably with cell culture The literal meaning of tissue culture refers to the culturing of tissue pieces, i.e. explant culture. Tissue culture is an important tool for the study of the biology of cells from multicellular organisms. It provides an "in vitro" model of
