Why would you expect gills to have an exceptionally large number of capillaries?
Capillaries, which are the smallest of the blood vessels, are the site of gas exchange...carbon dioxide diffuses out of surrounding cells into the gills to be lost into the environment, and oxygen diffuses from the environment into the gill cells and then surrounding tissues. The gills function like the lungs of a fish, so large numbers of capillaries in these structures function to supply oxygen/get rid of waste carbon dioxide for the organism.
Why do capillaries have such thin walls?
Capillaries have thin walls to optimise the level of diffusion of oxygen and other nutrients in the blood stream to the surrounding cells.
How do lympathtic capillaries differ from blood capillaries?
· Although similar to blood capillaries, lymphatic capillaries differ structurally in the following ways: · The endothelial cells forming the walls of lymphatic capillaries are not tightly joined. Their edges loosely overlap one another, forming flaplike minivalves. The flaps, anchored by fine collagen fibers to surrounding structures, gape open when the fluid pressure is high in the interstitial space, allowing it to enter the lymphatic capillary. · Bundles of fine filaments anchor the endothelial cells to surrounding structures so that any increase in interstitial fluid volume separates the cell flaps, exposing gaps in the wall rather than causing the lymphatic capillary to collapse.
Body cells surrounding capillaries usually have?
The body cells surrounding the capillary usually have low concentrations of oxygen and nutrients, but high concentrations of carbon dioxide and other waste products.
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 are the small vessels called where substances such as nutrientoxygen and carbon dioxide are exchanged for substances in the tissue fluid surrounding body cells?
Capillaries
What is Focal Adhesions and Hemidesmosomes?
Focal adhesions are temporal structures that attach motile cells to the matrix as they move through it while hemidesmosomes are more permanent structures that anchor epithelial cells to the underlying basal lamina.
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.
What so capillaries do in cells?
Capillaries do not occur in cells.Capillaries are larger than cells, indeed capillaries are made of cells.Capillaries are the smallest blood vesicles.
The transport of oxygen by hemoglobin occurs in the?
capillaries between the cells in the lungs or the capillaries between the cells in the body
What do capillaries pick up to bring to the lungs?
Capillaries surrounding cells pick up blood containing Water (dissolved in the plasma) and carbon dioxide (on the red blood cells) to bring it back through the veins and to the lungs. If I didn't answer your question or you want to ask more, post a message on my message board!
Do body cells that surround the capillaries usually have high nutrient concetration?
The body cells surrounding the capillary usually have low concentrations of oxygen and nutrients, but high concentrations of carbon dioxide and other waste products.
