Study Notes
Terminology
- Smallest to largest structures inside a cell: chemical (e.g., water, glucose, DNA), organelle (e.g., ribosomes, mitochondria), cell (e.g., neuron, red blood cell), tissue (e.g., muscle tissue, epithelial tissue), organ (e.g., stomach, heart), system (e.g., digestive system, respiratory system)
- Correct order of organization: Protein (chemical), Blood (tissue), Ribosome (organelle), Stomach (organ)
Functions and Organs of Body Systems
Cardiovascular System
- Function: Transports oxygen, nutrients, hormones, and waste.
- Major organs: Heart, blood vessels (arteries, veins, capillaries)
Endocrine System
- Function: Regulates body functions through hormones.
- Major organs: Pituitary gland, thyroid gland, adrenal glands, pancreas
Digestive System
- Function: Breaks down food, absorbs nutrients.
- Major organs: Mouth, esophagus, stomach, intestines, liver
Urinary System
- Function: Removes waste, maintains fluid/electrolyte balance.
- Major organs: Kidneys, ureters, bladder, urethra
Integumentary System
- Function: Protects the body, regulates temperature, prevents water loss.
- Major organs: Skin, hair, nails
Skeletal System
- Function: Provides structure, protects organs, stores minerals, aids movement.
- Major organs: Bones, cartilage, ligaments
Anatomical Position
- Body is standing upright, facing forward, arms at sides, palms forward
Anatomical Terms for Regions
- (List of anatomical regions is provided in the text)
Body Sections
- Frontal (coronal): Divides body into anterior and posterior parts.
- Transverse: Divides body into superior and inferior parts.
- Sagittal: Divides body into right and left parts.
Body Cavities and Contents
- Dorsal cavity
- Cranial cavity: Contains the brain.
- Spinal cavity: Contains the spinal cord.
- Ventral cavity
- Thoracic cavity: Contains lungs, heart.
- Abdominalpelvic cavity: Contains stomach, liver, intestines, bladder.
- General name for lining tissues: Ventral: Serous membranes, Dorsal: Meninges
Homeostasis
- Definition: Maintenance of stable internal conditions.
- pH homeostasis: Regulated by buffers, kidney function, respiration.
- Temperature homeostasis: Regulated by sweat production, shivering.
- Hormones: Insulin (high blood sugar), Glucagon (low blood sugar).
- Negative feedback examples: Body temperature regulation (sweating to cool down).
- Systems controlling homeostasis: Nervous system, Endocrine system
