Capillaries
Blood flows in capillaries, but there is blood leaks out from the capillaries, known as tissue fluid or interstitial fluid.
Pulmonary capillaries
The smallest blood vessels of the body = capillaries
capillaries
Each alveolar sac is surrounded by a network of capillaries that facilitate the exchange of gases (oxygen and carbon dioxide) between the air in the sac and the bloodstream. This close proximity allows for efficient gas exchange in the lungs.
This capillary network surrounds the tubules and plays an important role in secretion and reabsorption, plus it delivers oxygen to kidney cells.
The renal corpuscle consists of the glomerulus, which is a network of capillaries, and the Bowman's capsule, which is a cup-shaped structure that surrounds the glomerulus. Together, these components are responsible for the initial filtration of blood in the kidney.

First, the endothelial lining of the capillaries is traversed fol- lowed by movement through a matrix that surrounds synovial cells. This ultrafiltrate is combined with a mucopolysac- charide (hyaluronate) synthesized by the synovium.
Lymphatic fluid, or lymph, originates from interstitial fluid, which is the fluid that surrounds cells in tissues. It is formed when excess fluid, proteins, and waste products from blood capillaries seep into the spaces between cells. The lymphatic system collects this fluid through lymphatic capillaries, which transport it through lymph nodes and eventually return it to the bloodstream.
