RESPIRATORY
SYSTEM
Presented by:
AFFIFA MAQBOOL HUSSAIN
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.

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
Metabolic pathway that breaks
down glucose and produces ATP
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
ANATOMY
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
