Study Notes
Respiratory System Overview
- Primary functions include oxygen intake, carbon dioxide removal, disease resistance through air filtration, and airflow for speech.
- Comprised of two tracts: upper respiratory tract and lower respiratory tract.
Upper Respiratory Tract
- Components: Nose, nasal cavity, pharynx, larynx (voice box).
- Functions: Heats/cools air, filters air, provides sense of smell, and directs air to the lower airway.
Lower Respiratory Tract
- Components: Trachea (windpipe), lungs, bronchi, bronchioles, alveoli (small air sacs for gas exchange).
- Function: Supplies blood with oxygen.
Gas Exchange Terminology
- Ventilation: Movement of air from the environment into the lungs.
- Respiration: Gas exchange between the environment and body cells; oxygen enters the blood, carbon dioxide is removed.
- Breathing: Automatic process influenced by changes in carbon dioxide levels.
Mechanics of Breathing
- Inspiration: Process of bringing oxygen into the body.
- Expiration: Process of eliminating waste products by expelling air.
- Inhalation: Initiated by the medulla and pons; diaphragm contracts, increasing thoracic cavity size.
- Exhalation: Diaphragm relaxes and decreases thoracic cavity size, forces air out.
Muscles Involved in Respiration
- Primary muscles include the diaphragm and intercostal muscles.
- Abdominal muscles assist during forceful breathing.
Neural Control of Respiration
- Medulla: Primary control center for sending signals to respiratory muscles for inhalation/exhalation.
- Pons: Regulates rate and speed of involuntary respiration.
- Cerebral cortex: Controls voluntary respiration.
Cardiovascular System Overview
- Functions include transporting oxygen and nutrients to body cells, removing waste and carbon dioxide, and carrying hormones.
- Key components: Heart, blood, blood vessels (veins and arteries).
Heart Structure
- Located left of the chest center, above the diaphragm, between the lungs.
- Comprises four chambers: right atrium, right ventricle, left atrium, left ventricle.
- Contains four valves that regulate blood flow.
Blood Circulation
- Right side of the heart receives blood and sends it to the lungs.
- Left side receives oxygenated blood from the lungs and pumps it throughout the body.
Respiratory Conditions
- Various conditions can impact respiratory function; significant for speech-language therapy (SLT).
Cardiovascular Conditions
- Multiple cardiovascular diseases are prevalent and relevant to SLT practices.
Activities and Research Tasks
- Tasks include labeling diagrams of the respiratory and cardiovascular systems and understanding the functions of respiratory muscles.
