The tooth roots (pulp, dentin, endodont) are living tissue and have capillaries as well as nerves. The outer enamel consists of tubes of dead material in which the nerves gradually die off as it grows outward, toward the surface of the tooth. The remaining nerves become evident when teeth are drilled, as in the repair of cavities.

Are capillaries muscles or nerves a blood vessels?
Capillaries are the smallest blood vessels.
What do the capillaries carry to the body cells?

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.
Why are capillaries found in alveoli nephrons and villi?
Wherever capillaries are found, these are places where nutrients and wastes are exchanged.
What surrounds each alveolar sac?
Each alveolar sac is surrounded by a network of capillaries that facilitate the exchange of gases (oxygen and carbon dioxide) between the air in the sac and the bloodstream. This close proximity allows for efficient gas exchange in the lungs.
What does vasodentin mean?
A modified dentin permeated by blood capillaries and common in the teeth of the lower vertebrates.
Capillaries that have a incomplete lining are called?
continuous capillaries continuous capillaries
What structures connect the smallest arteries with the smallest veins?
Capillaries are the structures that connect arteries to veins.
What blood vessels surround the aveoli?
Capillaries The smallest of the blood vessels: capillaries.
What feeds the capillaries?
Arteries "feed" the capillaries while veins drain the capillaries.
Which veins open up into the capillaries?
plmonary veins begin as capillaries and end as capillaries
What are called leaky capillaries found in he one marrow?
Sinusoidal Capillaries
What smallest blood vessels only one cell thick?
The thin walled blood vessels are called capillaries.
Which capillaries are the most in the body?
continuous capillaries
The smallest and most numerous blood vessels in the human body?
The smallest blood vessels are the capillaries.
Capillaries connect what?
Capillaries connect small arteries to small veins. Capillaries are the site of gas exchange.
Which vessels branch from arteries?
The branches from arteries are arterioles and then into capillaries.
