So that white and red blood cells can pass through the capillaries
The lymphatic capillaries are made up of endothelial cells, which are thin-walled cells that line the inside of the vessels. These cells have small openings that allow fluid and molecules to enter the capillaries.
Capillaries are the smallest blood vessels in the body, consisting of a single layer of endothelial cells. They are where oxygen and nutrients are exchanged with tissues.
Capillaries are tiny blood vessels that consist of a single layer of endothelial cells. They have a diameter just large enough for red blood cells to pass through one at a time. Capillaries connect arterioles and venules in the circulatory system.
Capillaries are tiny blood vessels with a single layer of endothelial cells that allow for the exchange of gases, nutrients, and waste products between the blood and tissues. They are the smallest and most numerous type of blood vessel in the body, forming an extensive network for efficient transport of substances to and from cells.
Increased permeability of the endothelial-capsular membrane can be caused by factors such as inflammation, trauma, or infection. These conditions can disrupt the tight junctions between endothelial cells, leading to leakage of fluid and proteins from the blood vessels into the surrounding tissues.
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
Lymphatic capillaries are dead-end vessels interspersed between the vascular capillaries. They lack tight junctions between endothelial cells and therefore are more permeable to proteins than are vascular capillaries.
Endothelial cells make up the endothelium of capillaries. These cells form a single layer lining the interior surface of blood vessels, including capillaries, and play a crucial role in regulating the exchange of substances between the blood and surrounding tissues.

Lymphatic capillaries are closed at one end and they are tethered to surrounding tissues by protein filaments. Endothelial cells loosely overlap the lymphatic capillaries to allow bacterial and cells to enter the capillaries. The layout of the endothelial cells also create valve-like flaps which open when the interstitial fluid pressure is high and close when it is low.

organ is a structure made up of 2 or more no. of tissues(group of similar cells structurally and functionally)....artery is made up of endothelial cells, muscle fibres, elastic fibres etc placed in layers...hence is an organ. whereas capillaries only have endothelial cells.
like blood capillaries, their wall consists of a single layer of endothelial cells. Their permeability results from the structure and arrangement of the endothelial cells:they have few intercellular junctions, and the edges of adjacent cells overlap, filaments anchor the endothelial cells to the surrounding connective tissue. as a result, any increase in the volume of in the wall and allowing the fluid to enter. :)
the endothelial cells have pores (windows) to allow rapid movement of solutes and water.

blood-brain barrier (!)
Yes, Diapedesis is a process by which "white blood cells" escape from the capillaries into the tissue spaces, but not RBCs and Platlets.
