This article discusses our recent experience of lenders requiring counterparties to collateralize those swap obligations. âCollateralizationâ of a swap transaction refers to a situation where either or both parties to a swap are required to offer security or credit support for the risk that their counterparty is taking on the transaction at any given point in time.
The single cell layer of capillaries, although ideal for diffusion, creates problems. Capillary beds are easily destroyed. High blood pressure or any impact, such as caused by â¦ a punch, can rupture the thin-layered capillary.
The flow of blood in the capillaries is controlled by structures called precapillary sphincters. These structures are located between arterioles and capillaries and contain muscle fibers that allow them to contract. When the sphincters are open, blood flows freely to the capillary beds of body tissue.When the sphincters are closed, blood is not allowed to flow through the capillary beds. Fluid exchange between the capillaries and the body tissues takes place at the capillary bed.apillaries measure in size from about 5-10 microns in diameter. Capillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue). Oxygen, carbon dioxide, nutrients and wastes are exchanged through the thin walls of the capillaries.
