Interactions Between the Respiratory System and Other Organ Systems

indicates ways in which this system affects other systems indicates ways in which other systems affect this one

All Systems

The respiratory system serves all other systems by supplying O2, removing CO2, and maintaining acid-base balance

Integumentary System

^^ Nasal guard hairs reduce inhalation of dust and other foreign matter

Skeletal System

^^ Thoracic cage protects lungs; movement of ribs produces pressure changes that ventilate lungs

Muscular System

^^ Skeletal muscles ventilate lungs, control position of larynx during swallowing, control vocal cords during speech; exercise strongly stimulates respiration because of the CO2 generated by active muscles

Nervous System

^^ Produces the respiratory rhythm, monitors blood gases and pH, monitors stretching of lungs; phrenic, intercostal, and other nerves control respiratory muscles

Endocrine System

Lungs produce angiotensin-converting enzyme (ACE), which converts angiotensin I to the hormone angiotensin II ^^ Epinephrine and norepinephrine dilate bronchioles and stimulate ventilation

Circulatory System

Regulates blood pH; thoracic pump aids in venous return; lungs produce blood platelets; production of angiotensin II by lungs is important in control of blood volume and pressure; obstruction of pulmonary circulation leads to right-sided heart failure

^- Blood transports O2 and CO2; mitral stenosis or left-sided heart failure can cause pulmonary edema; emboli from peripheral sites often lodge in lungs

Lymphatic/Immune Systems

Thoracic pump promotes lymph flow ^^ Lymphatic drainage from lungs is important in keeping alveoli dry; immune cells protect lungs from infection

Valsalva Maneuver Childbirth

Urinary System

Valsalva maneuver aids in emptying bladder ^^ Disposes of wastes from respiratory organs; collaborates with lungs in controlling blood pH

Digestive System

Valsalva maneuver aids in defecation ^^ Provides nutrients for growth and maintenance of respiratory system

Reproductive System

Valsalva maneuver aids in childbirth ^^ Sexual arousal stimulates respiration

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
