RESPIRATORY SYSTEM- HUMAN ANATOMY AND PHYSIOLOGY

Respiratory System contributes to homeostasis by providing for exchange of gases– oxygen and carbon dioxide– between atmospheric air, blood and tissue cells.
It also helps adjust pH of body fluids.
Body’s cells continually use oxygen for metabolic reaction that generate ATP from the breakdown of nutrient molecule.

2. INTRODUCTION Respiratory System contributes to homeostasis by providing for exchange of gases– oxygen and carbon dioxide– between atmospheric air, blood and tissue cells. It also helps adjust pH of body fluids. Body’s cells continually use oxygen for metabolic reaction that generate ATP from the breakdown of nutrient molecule.

3. Pulmonary ventilation (Breathing) Transport of gases Cellular Respiration External respiration Internal Respiration 1 2 3 4 5 BREATHING PROCESS Exchange of air between atmosphere and alveoli of lungs Exchange of gas between alveoli of lungs and blood in pulmonary capillaries across the respiratory membrane Exchange of gas between blood in systemic capillaries and tissue cells M etabolic pathway that breaks down glucose and produces ATP

4. RESPIRATORY FUNCTIONS Respiration Gas exchange in alveoli Essential for oxygenation and carbon dioxide removal Filtration Removal of particles Cleansing inhaled air to protect the respiratory system Humidification Air moisture control Prepares air to prevent drying of the respiratory passages pH Regulation Acid-base balance maintenance Helps regulate pH by eliminating carbon dioxide Waste Excretion Removal of metabolic waste like Carbon dioxide Exhalation to eliminate Carbon dioxide

6. PARTS DESCRIPTION Nose Entry point for inhaled air; contains nasal passages Pharynx Passage for both air and food; connects nose to trachea Larynx Voice box; contains vocal cords; air passage to trachea Trachea Windpipe; carries air to and from the lungs Bronchi Primary airways branching from trachea; lead to each lung Bronchioles Smaller airways branching from bronchi; end in alveoli Alveoli Tiny air sacs; site of gas exchange in the lungs
