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
Vascular tissue neoplasm malignant vascular tumors are considered sarcomas, a major histological group of tumors, arising from transformed cells of mesenchymal origin. Vascular tissue neoplasm A vascular tissue neoplasm is a tumor arising from endothelial cells, the cells that line the wall of blood vessels and lymphatic vessels, as well as the heart. Vascular tissue neoplasms is a group containing tumors with the same tissue origin; in other words, it denotes histological classification, rather than anatomic (i.e. where in the body the neoplasm is found) or clinical one. They can occur everywhere in the body where vessels are to be found. Vascular tissue
