تعريف capillaries في الإنجليزية الإنجليزية القاموس.
The smallest blood vessels They form a fine network permeating the body's tissue
The smallest blood vessels Oxygen and nutrients leave the bloodstream through capillaries to get into the body Gases from the alveoli enter the bloodstream through capillaries in the lungs
any of the minute blood vessels, averaging 0 008 millimeter in diameter, carrying blood and forming the capillary system Capillaries connect the ends of the smallest arteries with the beginnings of the smallest veins
Small, narrow blood vessels that form bridges between arteries, which carry oxygen-rich blood away from the heart, and veins, which bring oxygen-depleted blood back to the heart Capillaries carry blood to and from cells in the body, allowing for exchange of oxygen, nutrients, carbon dioxide, and cell waste
Very small blood vessels which remove waste from and provide oxygen and nutrients to body cells
[from the Latin capillus, hair]: The tiny, often microscopic, vessels which nourish the tissues and transfer blood from the arteries to the veins
Capillaries, the smallest blood vessels in the body, form a network that allows blood and cells to exchange substances (such as oxygen)
tiny blood vessels that form the most distal part of the circulatory system Arteries branch into ever smaller vessels, finally ending in the capillaries, which connect with the smallest branches of the veins Capillaries deliver oxygen and nutrients to and remove waste products from the body's cells
Tiny blood vessels that allow the exchange of substances Has a single cell thick wall
Tiny blood vessels connecting arteries to vein These blood vessels carry oxygen and nutrients to individual cells
The smallest blood vessels in the body through which most of the oxygen, carbon dioxide, and nutrient exchanges take place
Microscopically small blood vessels between arteries and veins that distribute oxygenated blood to the body's tissues
The tiniest blood vessels; capillary networks connect the arterioles (the smallest arteries) and the venules (the smallest veins) (Read about "Vascular System")
Small blood channels that are the endpoints at which blood/nutrient exchange takes place
minute vessels that connect arterioles and venules (small branches of arteries and veins)
Any of the small blood vessels that connect arteries to veins. Their walls are composed of a single layer of cells which allows molecules such as oxygen, water and lipids to pass through them by diffusion and enter the tissues. Waste products such as carbon dioxide and urea can diffuse back into the blood to be carried away for removal from the body
a minute vessel connecting arterioles and venules, the walls of which act as a membrane for interchange of various substances between blood and tissue fluid The walls consist of thin endothelial cells through which dissolved substances and fluids can pass
the smallest of the body's blood vessels Oxygen and glucose pass through capillary walls and enter the cells Waste products such as carbon dioxide pass back from the cells into the blood through capillaries
a tube of small internal diameter; holds liquid by capillary action any of the minute blood vessels connecting arterioles with venules long and slender with a very small internal diameter; "a capillary tube"
A capillary is the narrowest type of blood vessel in the circulatory system Their walls are only one cell layer thick, so that oxygen and nutrients can pass through them into the surrounding tissues Capillaries also transport waster material (e g urea and carbon dioxide) to venules for ultimate excretion
A minute, thin-walled vessel; particularly one of the smallest blood vessels connecting arteries and veins, but used also for the smallest lymphatic and biliary vessels
= microscopically small blood vessels connecting the arterial and the venous side of the circulatory system and in which the exchange of substances takes place
Capillaries are tiny blood vessels in your body. capillaries the smallest type of blood vessel (=tube carrying blood) in the body. Any of the minute blood vessels that form networks where the arterial and venous circulation (see artery, vein) meet for exchange of oxygen, nutrients, and wastes with body tissues. Capillaries are just large enough for red blood cells to pass through in single file. Their thin walls are semipermeable, allowing small molecules to pass through in both directions. The smallest lymphatic vessels and minute bile channels in the liver are also called capillaries
Resembling a hair; fine; minute; very slender; having minute tubes or interspaces; having very small bore; as, the capillary vessels of animals and plants
The smallest of the body's blood vessels Capillaries have walls so thin that oxygen and glucose can pass through them and enter the cells, and waste products such as carbon dioxide can pass back into the blood to be carried away and taken out of the body Sometimes people who have had diabetes for a long time find that their capillaries become weak, especially those in the kidney and the retina of the eye See also: Blood vessels
Any of the small blood vessels that connect arterioles to venules. Their walls are composed of a single layer of cells which allows molecules such as oxygen, water and lipids to pass through them by diffusion and enter the tissues. Waste products such as carbon dioxide and urea can diffuse back into the blood to be carried away for removal from the body
