Study Notes
Organ Systems
-
Nervous System: controls body functions, interprets sensory information, and facilitates communication between different parts of the body
- Central Nervous System (CNS): brain and spinal cord
- Peripheral Nervous System (PNS): nerves and ganglia
-
Circulatory System: transports oxygen and nutrients to cells, and removes waste products
- Heart: pumps blood throughout the body
- Blood vessels: arteries, veins, and capillaries
-
Respiratory System: brings oxygen into the body and removes carbon dioxide
- Lungs: exchange oxygen and carbon dioxide
- Airways: trachea, bronchi, and bronchioles
-
Digestive System: breaks down food into nutrients for energy and growth
- Mouth: mechanical digestion and salivary enzymes
- Stomach: chemical digestion and gastric enzymes
- Small intestine: nutrient absorption
- Large intestine: water absorption and waste elimination
-
Endocrine System: produces and regulates hormones
- Glands: pituitary, thyroid, adrenal, pancreas, and gonads
-
Integumentary System: protects the body from external damage and regulates body temperature
- Skin: epidermis, dermis, and hypodermis
- Hair, nails, and sweat glands
-
Muscular System: moves the body and maintains posture
- Skeletal muscles: voluntary movement
- Smooth muscles: involuntary movement
- Cardiac muscles: heart contraction
-
Skeletal System: supports the body and protects internal organs
- Bones: 206 bones in the adult human skeleton
- Joints: connect bones and allow for movement
-
Urinary System: filters waste and excess fluids from the blood
- Kidneys: filtration and urine production
- Ureters: transport urine to the bladder
- Bladder: urine storage
- Urethra: urine elimination
Body Regions
- Cranial Region: head and skull
- Facial Region: face and neck
- Thoracic Region: chest and lungs
- Abdominal Region: abdomen and digestive organs
- Pelvic Region: pelvis and reproductive organs
- Upper Limb Region: arms and hands
- Lower Limb Region: legs and feet
Body Cavities
- Cranial Cavity: contains the brain
- Thoracic Cavity: contains the lungs, heart, and major blood vessels
- Abdominal Cavity: contains the digestive organs and kidneys
- Pelvic Cavity: contains the reproductive organs and urinary bladder
Other Key Concepts
- Homeostasis: maintenance of a stable internal environment
- Anatomical Position: standard reference position for the human body
- Directional Terms: used to describe the location of body structures
- Body Planes: imaginary planes that divide the body into sections
