Study Notes
Respiratory System
- Primary function: Gas exchange between the body and the environment
- Sound production: Larynx
- Breathing muscle: Diaphragm (contracts and relaxes)
- Air filtration: Nasal cavity (warms and moistens)
- Important structure for swallowing: Epiglottis (prevents food from entering the trachea)
- Non-vital function: Speech production
- Alveoli lining: Simple squamous epithelium
- Surfactant secretion: Type II alveolar cells
- Removing pathogens and debris in lungs: Alveolar macrophages
- Filtering blood: Not a function of the respiratory system
- Ciliated lining for filtering: Trachea and nasal cavity (trachea assists in cleaning debris.
Digestive System
- Nutrient absorption (majority): Small intestine
- Water absorption and waste formation: Large intestine
- Mechanical digestion: Stomach
- Enzyme digestion of carbohydrates: Amylase (in saliva)
- Bile storage and concentration: Gallbladder
- Enzyme production for carbohydrates, proteins, and fats: Pancreas
- Hydrochloric acid production: Parietal cells (in stomach)
- Food movement: Peristalsis (regulated by the myenteric plexus)
- Nutrient absorption increase: Villi and microvilli in the small intestine (increase the surface area)
- Connects pharynx to stomach: Esophagus
- Retroperitoneal organ: Pancreas
- Digestive enzymes secretion: Acinar cells (in pancreas)
- Function of intrinsic factor: Secreted by parietal cells (important for vitamin B12 absorption)
- Liver function: Bile production
Other
- Myenteric plexus function: Controls peristalsis and segmentation (movement and mixing of food)
- Esophagus lining: Stratified squamous epithelium
