Relationship between bronchioles alveoli and blood vessels are

They are both actively involved in gaseous exchange in the body and they are both associated with the lungs.

Explanation: The lungs contain the bronchi and alveoli. The relationship between them is that they are both involved gaseous exchange in the lungs and the body.

Alveoli are tiny sacs inside the lungs it allows oxygen and carbon dioxide to move between the lungs and bloodstream.

Bronchi connect the trachea and lungs, they are pathways that shuttle air to and from the lungs and subsequently outside the body.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
