What else can I help you with?
The density of capillaries within a tissue varies directly with the tissues?
rate of metabolism
Capillaries are to body tissues as are to lungs?
oxygen
What is role of capillaries?
exchange of nutrients and gasses with tissues
What is the role the capillaries?
exchange of nutrients and gasses with tissues
What is the role of the capillaries?
Capillaries are very small blood vessels found within the tissues of the body. Its primary role is to transport blood from arteries to the veins.
Why do most tissues have a greater supply of capillaries than veins and arteries?
Capillaries service cells, arteries and veins transport blood to and from capillaries, respectively.
Are capillaries cells?
No, capillaries are tissues that form tubes to transport blood throughout the body. They are made of thousands of cells.
Where in the circulatory cyctem does nutrients enter and wastes leave the tissues?
The capillaries are the site in the circulatory system where nutrients enter and wastes leave the tissues. The thin walls of the capillaries facilitate this diffusion.
What is the principle force that causes movement of fluid from tissues into capillaries?
The principle force that causes movement of fluid from tissues into capillaries is oncotic pressure. This pressure is generated by the presence of proteins in the blood that draw fluid back into the capillaries by osmosis.
What substances come out of the blood in the exchange at capillaries?
Oxygen and nutrients are delivered from the blood to tissues, and waste products such as carbon dioxide and metabolic byproducts are removed from tissues and transferred into the blood in the exchange at capillaries.
The velocity of blood is slowest in the?
The velocity of blood is slowest in the capillaries. This allows for maximum exchange of nutrients, gases, and wastes between the blood and the surrounding tissues.
