Diapedesis
diapedesis
Diapedesis is the process by which white blood cells squeeze through the walls of capillaries and enter tissue spaces to reach sites of inflammation or infection in the body. This is an essential part of the immune response to pathogens.

Diapedesis
the passage of blood cells, esp. leukocytes, through the unruptured walls of the capillaries into the tissues.Leukocyte extravasation is the movement of leukocytes out of the circulatory system, towards the site of tissue damage or infection. This process forms part of the innate immune response, involving the recruitment of non-specific leukocytes. Monocytes also use this process in the absence of infection or tissue damage during their development into macrophages.

By a process called "capillary" action.
diapedesis
When white blood cells leave the capillaries, this process is called diapedesis or extravasation. It allows white blood cells to move from the blood vessel into the surrounding tissues to reach sites of infection or inflammation.
Osmosis through the roots, then capillary action up the trunk and branches.
The flow of blood through a capillary bed is called capillary circulation. It involves the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. Blood enters the capillary bed through arterioles and exits via venules, allowing for efficient nutrient delivery and waste removal at the cellular level. This process is crucial for maintaining tissue health and homeostasis.
Yes, water can travel upwards through a process called capillary action, where water moves against the force of gravity through small spaces in a material. This phenomenon is seen in plants, where water moves from the roots to the leaves through capillary action.
