Bronchi, Bronchioles and Alveoli.
Bronchi and Bronchioles
- transport systems
Alveoli
- Respiration occurs
consist of nasal with mouth untill lung
No there isn't. The alveoli (air sack) consist of an epithelial layer and extracellular matrix surrounded by capillaries.
There are about 30,000 of them in each lung.
There are 10 bronchi in each lung.
the left and right bronchi
Pleura is a double layered membrane surrounding each lung.
Consisting of thousands of tiny air sacs increases the surface area inside of the lung which allows for better gas exchange. If the lung was made of one larger air sac, you would not be able to exchange as many gases (oxygen/CO2) with each breath.
Trachea
Bronchi are the two tubes that branch off into each lung.
Each lung of a fetal pig has four lobes: the cranial, middle, caudal, and accessory lobes.
Pleura is a double layered membrane surrounding each lung.
