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.

The trachea branches off into two tubes going to each lung called the Bronchial Tubes.

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.
