Portion of lungs that extends above the clavicle

What do you call the structures passing through the hilium

Forms the base of larynx ; upon which other cartilages rest

Movement of gases between the bloodband body's cell

Indentation on the medial surface of the lungs

Larynx: contains superior pair of ligaments ; false vocal cord

Division of trachea that forms primary bronchi

Movement of gases between atmospheric air in lungs and blood

Chambers connected to 2 or more alveoli at the end of an alveolar duct

Nose to larynx

Arise mainly from main bronchi

Diffusion of gases across the membrane

A smooth muscle that can narrowndown the diameter of trachea by contracting, which aids coughing

Result from continued branchingnof the segmental bronchi

Trachea to alveoli of the lungs

Spaced enclosed by thoracic wall and diaphragm

Supply subdivisions within each lobe

4th process for gas exchange between air and blood

3rd process for gas exchange between air and blood

- site of pulmonary gas exchange - small, air-filled chambers where air and blood comes into close contact

Largest cartilage, also known as the adam's apple

- primary organs for gas exchange - among the largest orgams of the body

Attached to the superior tips of thr arythenoid cartilage

Opening at the junction of vocal folds

Type of cell of alveolar wall: round or cube shaped secretory cells that produce surfactant, which make it easier for alveoli tonexpand during respiration

Type of cell of alveolar wall: 90% of alveolar surface where most of gas exchange between alveolar air and blood takes place

2nd process for gas exchange between air and blood

Posterior opening inti the pharynx

Contained in a mucous membrane anterior to the corniculate cartilage

Arise from several subdivisioms of bronchioles

- attached to the thyroid cartilage - a freely movable flap - helps divert food away from trachea opening

- floor of nasal cavity - separates oras cavity in the mouth - formed by palatine process of maxillae and palatine bone

Nose to smallest airtubes in lungs ; pulmonary ventilation

Articulate with superipr border on the posterior of the cricoid cartilage

Respiration consist of 2...?

A ridge of cartilage that serves as an important landmark for reading x-rays. Its mucous membrane is sensitive to mechanical situation

- has few attached alveoli - as respiratory bronchioles divide to form smaller repiratory bronchioles, the number of attached alveoli increases

Deep to the connective tissue that surrounds each lungs called visceral pleura

Consist of trachea and network of airtube in lungs

1st process for gas exchange between air and blood

- opens the chamber inside the nose - where air 1st enter

Movement of air into and out of the lungs

- C Shaped pieces of hyaline cartilage - supports trachea and prevent it from collapsing

Smooth muscle relaxes, making bronchiole larger

Portion of lungs in contact with diaphragm

Solely lungs and includes some specialized small air tubes and alveoli ; gas exchange

Resistance to airflow is proportional to the diameterbof a tube. Thus, a small change in diameter results in ablarge change in resistance, which greatly decrease airflow

Formed by alveolar walls amd surroundingbpulmonary capillaries; Location of pulmonary gas exchange and is extremely thin to facilitate diffusion of gases

Commonly known as the windpipe

Smooth muscle contracts, making bronchiole diameter smaller

Anterior external opening

Larynx: contains inferior ligaments; true vocal cords

Arise from respiratory bronchioles; are long, branching hallways with many open doorways

Called the "voice box" because it houses the ligaments used for speech

Follows the bronchi and drain lymphs from bronchi and associated connective tissue
