The tiniest tubes in the circulatory system, known as capillaries, are closely related to the air sacs in the lungs, called alveoli. Capillaries surround the alveoli and facilitate the exchange of oxygen and carbon dioxide between the air in the alveoli and the blood. This process allows oxygen to enter the bloodstream while carbon dioxide is expelled from the blood, highlighting the interconnectedness of the respiratory and circulatory systems in maintaining body oxygenation.
They are called capillaries and are involved in the process of capillary exchange where they supply each living cell in your body with the nutrients it needs to survive and also carries away their waste products. The tiniest tubes are the capillaries.
Closed circulatory system.

yes
a The Circulatory System has 2 tubes on oxygenated rube which is blood with oxygen and deoxygenated tube which the blood is not carrying oxygen
The blood vessels of the circulatory system is the system of tubes that carry blood in vertebrates. These vessels include veins, arteries, and capillaries.
by getting all the food down the tubes
segmented worms have a closed circulatory system.in a closed circulatory system, blood moves only within a connected network of tubes called blood vessels.
Cardiovascular (translated loosely it means "heart tubes/pipes").
