Sinusoids are channels found in which organ?

Explanation:
Sinusoids are a special, highly permeable type of capillary designed for quick exchange between blood and tissue. In the liver, hepatic sinusoids span between rows of hepatocytes and carry blood from both the portal vein and hepatic artery to the central veins. Their lining is fenestrated endothelium with little or no basement membrane, making them more permeable than typical continuous capillaries. This structure supports the liver’s roles in filtering, metabolizing, and detoxifying substances, while also allowing immune cells to patrol the tissue. Although other organs can have sinusoid-like vessels, the liver is the classic organ described as having sinusoids in standard anatomy and physiology contexts.
