What cells form a porous membrane surrounding the endothelial cells of the glomerulus?
podocytes
Describe the process of synovial fluid formation?
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.
What is the name of the cells in the nephron that respond to ADH and aldosterone?
Endothelial
What do the capillaries carry to the body cells?
Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
During detachment how do cancer cells cause lysis of the basement membrane of the host cell?
adhesion of cancer cells to the underlying basement membrane [35108]. ... interaction with other cancer cells, host cells, and subendothelian and/or other ..... attachment or to cause detachment of the endothelial cells from ...... exhibited during cancer cell interaction with endothelial cells or blood elements ...
What vessels exchange materials with the extra cellular fluid and the blood?
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.
Are lymphatic capillaries permeable to proteins?
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.
What is it called when plasma moves out of the capillaries and into the spaces between tissue cells?
chyme
What are lymphatic capillaries like?
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.
What is a pericyte?
Pericytes consist of contractile cells that interact with the endothelial cells by covering them. The endolethial cell holds capillaries and venules.
Why are arteries organs but capillaries not?
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.
Anatomical adaptations which enable lymphatic capillaries to absorb tissue fluid?
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. :)
Interstitial fluid contains or is?
Found in spaces between cells and becomes lymph when it enters lymph capillaries.
What can be said about the endothelium of fenestrated capillaries?
the endothelial cells have pores (windows) to allow rapid movement of solutes and water.
Certain capillaries in the brain including the choroid plexus do not have spaces between the cells effectively creating a?
blood-brain barrier (!)
What cell type makes up the endothelium of capillaries?
Endothelial cells also known as epithernal tissue.
Is diapedesis the process by which red blood cells move into tissue spaces from the interior of blood capillaries?
Yes, Diapedesis is a process by which "white blood cells" escape from the capillaries into the tissue spaces, but not RBCs and Platlets.
