Diapedesis
The layers of the respiratory membrane include the alveolar epithelium, the basement membrane, and the capillary endothelium. These layers are involved in facilitating the exchange of gases, such as oxygen and carbon dioxide, between the air in the lungs and the blood in the capillaries.
Molecules traveling within the bloodstream pass through the capillary cell wall via osmotic pressure and diffuse through the interstitial fluid before encountering the tissue cell wall.
Endothelial
Endothelial lining refers to the layer of cells that line the interior surface of blood vessels and lymphatic vessels. These cells play a crucial role in regulating blood flow, maintaining blood pressure, and facilitating the exchange of nutrients and waste products between the blood and surrounding tissues.
Endothelial tissue forms the inner lining of blood vessels. This thin layer of cells plays a crucial role in regulating vascular tone, blood flow, and the movement of substances between the bloodstream and surrounding tissues.

The endothelium is the medical term meaning lining of the blood vessels, including those of the heart. It is continuous with the endocardium, the inner lining of the heart chambers and heart valves.
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.
Endothelial cells form the inner lining of a blood vessel and provides an anticoagulant barrier between the vessel wall and blood. Endothelial cells also generate an antithrombotic surface that facilitates transit of plasma and cellular constituents throughout the vasculature. As a selective permeability barrier, the endothelial cell is a unique multifunctional cell with critical basal and inducible metabolic and synthetic functions.

Endothelial cells also generate an antithrombotic surface that facilitates transit of plasma and cellular constituents throughout the vasculature. As a selective permeability barrier, the endothelial cell is a unique multifunctional cell with critical basal and inducible metabolic and synthetic functions. The endothelial cell reacts with physical and chemical stimuli within the circulation and regulates hemostasis, vasomotor tone, and immune and inflammatory responses. In addition, the endothelial cell is pivotal in angiogenesis and vasculogenesis.
Oxygen diffuses through two layers of cells: the alveolar epithelial cells lining the lung air sacs and the capillary endothelial cells before it reaches a red blood cell in the pulmonary capillaries.
Yes, that is correct. Diapedesis is the process by which white blood cells (WBCs) exit blood vessels by squeezing through the gaps between endothelial cells lining the vessel walls. This allows WBCs to migrate towards sites of infection or inflammation in the body.
