APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Lymphatic capillaries start as blind-ended sacs in the periphery and merge to collecting lymphatic vessels, which are surrounded by pericytes and have valves to direct the flow into the draining lymph nodes (Figure 1).

Detailed explanation-2: -The smallest lymphatic vessels are the lymph capillaries, which begin in the tissue spaces as blind-ended sacs. Lymph capillaries are found in all regions of the body except the bone marrow, central nervous system, and tissues, such as the epidermis, that lack blood vessels.

Detailed explanation-3: -Lymphatic capillaries are very thin vessels which are blind-ended tubes. These lacteals have a thickness of a single cell, but the cells are arranged in an overlapping manner so that the fluid from the outside can enter it with relative ease.
