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
Cerebral edema such as ischemic stroke, cancer, or brain inflammation due to meningitis or encephalitis. Vasogenic edema caused by amyloid-modifying treatments, such as monoclonal antibodies, is known as ARIA-E (amyloid-related imaging abnormalities edema). The blood–brain barrier (BBB) or the blood–cerebrospinal fluid (CSF) barrier may break down, allowing fluid to accumulate in the brain's extracellular space. One manifestation of this is P.R.E.S., or Posterior Reversible Encephalopathy Syndrome. Altered metabolism may cause brain cells to retain water, and dilution of the blood plasma may cause excess water to move into brain cells. Fast travel to high altitude without proper acclimatization can cause high-altitude cerebral
