Rats are various medium sized long-tailed Rodents of the superfamily Muroidea Fenestrae are approx 100 nm diameter, and the sinusoidal width 5 µm.

A liver sinusoid is a type of sinusoidal blood vessel (with fenestrated, discontinuous endothelium) that serve as a location for the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein. A sinusoid is a small Blood vessel similar to a Capillary but with a Discontinuous Endothelium. ^[1]

Liver sinusoids are equipped with Kupffer cells that can take up and destroy foreign material such as bacteria entering the sinusoids. Kupffer cells, also known as Browicz-Kupffer cells, are specialized Macrophages located in the Liver that form part of the Reticuloendothelial system Phagocytosis is the cellular process of engulfing solid particles by the Cell membrane to form an internal Phagosome, or "food vacuole The Bacteria ( singular: bacterium) are a large group of unicellular Microorganisms Typically a few Micrometres in length bacteria have
