Diapedesis
Chemotaxis
called chemotaxis. Chemicals released from damaged cells act as signals that guide leukocytes to the site of injury or infection, helping to initiate the inflammatory response and target the source of damage for immune defense and repair.
Leukocytes make antibodies.
Leaky capillaries found in the bone marrow are called sinusoidal capillaries. These specialized capillaries allow larger cells like blood cells to move in and out of the bloodstream more easily due to their larger size and more permeable nature. This facilitates the movement of cells between the bone marrow and blood circulation.

Sinusoidal Capillaries
Fluid enters the lymphatic system (this system returns fluid and proteins to blood) by diffusing into lymph capillaries. This fluid is now called lymph and is kind of like interstitial fluid in composition. This movement of fluid is determined by net balance. It only diffuses into the capillaries if there isn't enough fluid there to begin with.
They are called leukocytes.
These are called the alveoli capillaries.
