pulmonary arterioles

Explanation:

Pulmonary arterioles are small blood vessels located in the lung. They appear as branches of the major arteries and have the main function of releasing blood from capillaries, in addition to regulating blood flow and peripheral blood pressure in capillaries.

It is important to note that arterioles are very small in size, which facilitates their functions to be performed efficiently and quickly.
