However, this route is slow. While cells in blood vessels and in most other lymphatic vessels are carried along by a flow of fluid, virtually no flow is present in lymphatic capillaries. Consequently, ...

The lymphatic system is a network of branching vessels that regulate fluid balance and support the immune system. Its smallest capillaries, comprised of a single endothelial cell layer, must stay ...

In its response to pathogens and vaccines, our immune system relies on dendritic cells. These white blood cells patrol the body's tissues, collect components of pathogens and vaccines and transport ...

The cells that make up the walls of the finest of all lymphatic vessels have a lobate, oak leaf-like shape that makes them particularly resilient to changes in fluid volume. A similar cell shape also ...

Certain cells have an unusual shape that is similar to an oak leaf or puzzle piece, and researchers have found that the form of these cells helps them withstand dramatic changes in volume. These cells ...

You have just enjoyed a delicious summer BBQ. After approximately eight hours, food molecules reach your small intestine, where specialized lymph capillaries, called lacteals, absorb fat nutrients.
