Study Notes
Integumentary System
- Skin is the largest external organ, acting as an excretory, sensory, and temperature-regulating organ.
- Skin has receptors for heat, cold, pain, and touch.
- Skin has three layers:
- Epidermis: Outermost layer, a barrier against infections. Made of dead cells that are constantly shed and replaced. Contains pores for sweat and oil excretion.
- Dermis: Middle layer, containing nerve endings, hair follicles, sweat glands, and oil glands.
- Hypodermis: Innermost layer, composed of fat, blood vessels, and connective tissue, maintaining body temperature.
- Melanin, a pigment in the skin, is responsible for skin color and protects from UV rays.
Digestive System
- The digestive system processes food for nutrient absorption and waste removal.
- Two types of digestion:
- Mechanical: Physically breaks down food (e.g., chewing, churning in stomach).
- Chemical: Breaks down food into simpler molecules (e.g., enzymes).
- Digestive system organs and their roles:
- Mouth: Ingestion and initial mechanical digestion.
- Esophagus: Transports food from mouth to stomach.
- Stomach: Temporarily stores food, secretes gastric juices to begin chemical digestion.
- Small intestine: Completes digestion and absorbs nutrients.
- Large intestine: Absorbs water from undigested food; forms and expels feces.
- Liver: Produces bile to aid in fat digestion.
- Gallbladder: Stores bile.
- Pancreas: Produces enzymes to aid in chemical digestion of carbohydrates, fats, and proteins.
Respiratory System
- The respiratory system facilitates breathing and gas exchange (oxygen intake, carbon dioxide release).
- Key parts and functions:
- Nose: Entryway for air, lined with cilia to filter.
- Pharynx: Passageway for air and food.
- Larynx: Voice box, contains vocal cords.
- Trachea: Windpipe, carries air to lungs.
- Bronchi: Branches of trachea leading to lungs.
- Lungs: Main organs for gas exchange, made of alveoli for efficient gas exchange.
