branchioles : A pulmonary lobule is the portion of the lung ventilated by one bronchiole. Bronchioles are approximately 1mm or less in diameter and their walls consist of ciliated cuboidal epithelium and a layer of smooth muscle.
cappillaris : are the smallest of a body's blood vessels and are parts of the microcirculation. They are only 1 cell thick. These microvessels, measuring 5-10 μm in diameter, connect arterioles and venules, and enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues
What else can I help you with?
Is the bronchiole surrounded by blood capillaries?
No, bronchioles are part of the respiratory system and are not surrounded by blood capillaries. Bronchioles are airways within the lungs that help transport air to the alveoli for gas exchange. Blood capillaries are located near the alveoli for the exchange of oxygen and carbon dioxide.
What are the small branches of tubes that lead to alveoli?
Not sure what exactly you are looking for here... but starting from the mouth: Pharynx Trachea Bronchi Bronchioles Alveoli
What path does air take when you inhale?
Mouth/nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and capillaries.
What three types of vessels are seen when you section the lungs?
Pulmonary artery, pulmonary vein, and bronchioles.

At the end opf the bronchioles are small air sacs called what which is where the oxygen enters the blood through the capillaries?
They are called alveoli
What is the job of the bronchioles?
The brochiole's function is to allow oxygen to pass into the aveoli (air sacks covered in capillaries) where the oxygen can then enter your blood stream.
What kind of blood cells surround the alveoli?
Alveoli are covered with capillaries. The deoxygenated blood that has come into the lung through the arteries flows through these capillaries, getting rid of carbon dioxide and accepting oxygen from the air that has been brought into the alveoli by the bronchioles. The carbon dioxide travels back out of the alveoli, through the bronchioles, into the bronchial tube system, and out the trachea each time you exhale.
What are the micro and macro structures of the lungs?
The macro structures of the lungs are what you can see. They would be the lobes of the lungs, bronchi, large blood vessels, lymph nodes and bronchioles. The micro structures are one you can not see without a microscope. That would be the vey small bronchioles, capillaries and the alveoli.
What is relationship of the alveoli to capillaries?
The alveoli branch from the bronchioles and are responsible for gas exchange with the pulmonary capillaries. They come in close contanct with the capillaries so the exchange of O2 and Co2 can occur rapidly and easily.
What is the part of the resporty tree which the alveoli are attched?
The alveoli are attached to the respiratory tree at the terminal bronchioles, which are the smallest branches of the bronchi. From the bronchioles, air passes into the alveolar ducts and then into the alveolar sacs, where the alveoli are clustered. This structure allows for efficient gas exchange between the air in the alveoli and the blood in the surrounding capillaries.
What are the 3 types of bronchioles?
The three types of bronchioles are terminal bronchioles, respiratory bronchioles, and conducting bronchioles. Terminal bronchioles are the smallest airways in the respiratory system that lead to the respiratory bronchioles where gas exchange occurs. Conducting bronchioles are larger airways that branch off the main bronchi and help to conduct air to the smaller bronchioles.
