The bronchial tubes lead to the lungs from the esophagus. They are not blood vessels.they branch off of the lungs.
They are called alveoli
Bronchioles
Nose(nasal cavity),larynx,pharynx,trachea,bronchi,bronchioles,alveoli (lungs)
Bronchovascular markings are normal marking of blood vessels of the lungs which supplies to the bronchi and bronchioles and fluid overload is increase in midzones.
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.
The bronchi (their bronchioles) end in the air sacs (alveoli). These are where oxygen enters the blood vessels, and carbon dioxide is removed.
The main structures of the respiratory system are:mouthnosepharynx (throat)larynx (vocal cords)trachea (windpipe)bronchi (singular is bronchus; these are the two smaller tubes that are branches of the trachea)bronchioles (even smaller tubes off of the bronchi)lungsalveoli (singular is alveolus; these are tiny sacs on the bronchioles that are surrounded by blood vessels that allow oxygen into the blood)
Bronchioles are the small branches coming off the bronchi going to avioles which is blood like leaders
how do the bronchi allow the oxygen to get to the blood
The target organ for epinpehrine are many different organs and tissues, some of which include: the heart, blood vessels in skeletal muscle, blood cessels in skin and viscera, intestines, bronchioles, and the liver. Norepinephrine is the same for epinephrine.
Aveloli are the structures within the lungs, at the terminal end of bronchioles. They are not blood vessels. Aveoli resemble a cluster of grapes hanging off the smallest branches of a tree, with the tree upside down. The main bronchus in the upper chest is like the tree trunk, the bronchi branch and thin to bronchioles, then end at the aveoli. There O2 and CO2 exchange takes place.
Blood Vessels-are the passageway of blood.
