Upper airway system nasal cavity, nasopharynx, oropharynx, laryngopharynx, larynx
Lower Airway trachea, bronchioles, alveoli
Systems of the respiratory system Upper airway
Lower airway
Chest wall
Pulmonary Circulation
the movement of air into and out of the lungs ventilation
movement of particles from a high concentration and low concentration Diffusion
the way that blood moves and delivers oxygen to the tissues. Perfusion
mucus secreting cells Globet Cells
hyperplasia of globes cells bronchitis
moves particles to oropharynx Cilia
secrete antibacterial enzymes serous glands
what does nicotine do to the cilia paralyzes them
,how many division of bronchioles are there 16-23
primary gas exchange happens here alveoli
allow movement of macrophages pores of kahn
- Provides structure
- Once killed off, they cannot regenerate Type 1 Alveolar Cells
- Can regenerate
- Produces surfactant
- Allows alveoli to stay opens Type 2 Alveolar Cells
surrounding inside of thorax
lines the pulmonary cavity Parietal
- Around organs
- Adherent to all surfaces
- Continuous with parietal at the hilum Visceral
Edema in the pleural cavity effusion
low pressure system
Responsible for gas exchange pulmonary
, supplies lung tissues
blood supply for conducting airways and supporting structures bronchial
Pulmonary artery leaves the __________ ________ with unoxygenated blood, divides and enter the
lungs at the ________ R ventricle
Hilum
Delivery of O2 to the cells 1: Air into and out of lungs (ventilation)
2: Diffusion of O2 from alveoli to capillaries
3: Adequate perfusion of the blood (perfusion)
4: Diffusion of O2 from the capillary to the body cells & tissue
CO2 exchange 1: Diffusion of Co2 from the tissue cells into systemic capillaries
2: Perfusion of the pulmonary capillary bed by venous blood
3: Diffusion of CO2 from capillaries into the alveoli
4: Removal of Co2 from the lung (ventilation)
how to prevent atelectasis lungs must be rotated frequency so all parts of the must perfuses
Relationship between ventilation and perfusion expressed in V/Q
Gas exerts pressure partial pressure
Air moves between atmosphere and lungs because of pressure differences Gradient
