  • Inspiratory muscles contract

  • Thoracic volume increase

  • Lungs are stretched and intrapulmonary volume increases

  • Intrapulmonary pressure drops

  • Air flows into lungs

Expiration

  • Inspiratory muscles relax

  • Decrease in thoracic volume

  • Decrease in intrapulmonary volume

  • Increase in intrapulmonary pressure

  • Air flows out of lungs

Pharynx - connects the nasal cavity and mouth to the larynx and oesophagus, playing a role in respiration and digestion


Larynx - located in the anterior aspect of the neck, protect the lower respiratory tract from aspirating food into the trachea


Trachea - is a midline structure, allow passage of inspired and expired air into and out of the lung


Bronchi - passageways that connect your windpipe to your lungs


Alveoli - tiny air sacs in the lungs where gas exchange occurs


Diaphragm - contracts rhythmically and continually, and most of the time, involuntarily

Cell Types that make up alveolar tissue

Type I alveolar cells - facilitate gas exchange

Type II alveolar cells - Produce surfactant to reduce surface tension

  • Air enters lungs, reaching alveoli.

  • Oxygen diffuses from alveoli into blood.

  • Carbon dioxide diffuses from blood into alveoli.

  • Oxygen-rich blood is transported to tissues.

  • Carbon dioxide is expelled through exhalation.

  • Gas exchange is regulated by oxygen, CO2, and pH levels.

  • Oxygen enters alveoli.

  • Oxygen diffuses into blood.

  • Binds to hemoglobin in red blood cells.

  • Oxygen-rich blood circulates to tissues.

  • Oxygen is released to cells.

  • Deoxygenated blood returns to lungs for reoxygenation.

All structures must work together to ensure efficient oxygen uptake and carbon dioxide removal.

  • The respiratory system interacts with the cardiovascular system through gas exchange in the alveoli and oxygen transport via hemoglobin in red blood cells.


  • The respiratory system interacts with the endocrine in situations such as the release of Epinephrine. It binds to receptors in the airways, causing the bronchioles to dilate (a process called bronchodilation). This dilation increases airflow to the lungs, allowing more oxygen to enter the bloodstream.
