Study Notes
Organ Systems
- Nervous System: controls body functions, interprets and responds to stimuli
- Central Nervous System (CNS): brain, spinal cord
- Peripheral Nervous System (PNS): nerves, ganglia
- Circulatory System: transports oxygen, nutrients, and waste products
- Heart: pumps blood
- Blood vessels: arteries, veins, capillaries
- Respiratory System: brings oxygen into the body, removes carbon dioxide
- Lungs: exchange oxygen and carbon dioxide
- Trachea, bronchi, diaphragm: facilitate breathing
- Digestive System: breaks down and absorbs nutrients
- Mouth: mechanical and chemical digestion
- Stomach: chemical digestion
- Small intestine: nutrient absorption
- Large intestine: water absorption, waste elimination
- Endocrine System: produces and regulates hormones
- Glands: pituitary, thyroid, adrenal, pancreas, etc.
- Integumentary System: protects the body from external damage
- Skin: epithelial tissue, sweat glands, hair follicles
- Associated organs: nails, hair, exocrine glands
- Muscular System: moves the body, maintains posture
- Skeletal muscles: voluntary movement
- Smooth muscles: involuntary movement
- Cardiac muscles: heart function
- Skeletal System: provides support, protection, and movement
- Bones: 206 bones in the adult human skeleton
- Joints: connect bones, allow for movement
- Urinary System: filters waste and excess fluids from the blood
- Kidneys: filter waste and excess fluids
- Ureters: transport urine to the bladder
- Bladder: stores urine
- Urethra: eliminates urine from the body
Body Regions
- Head: contains the brain, sensory organs, and facial features
- Neck: connects the head to the torso
- Torso: contains the chest and abdominal cavities
- Upper limb: arm, forearm, hand
- Lower limb: thigh, leg, foot
- Back: posterior region of the torso
Body Cavities
- Cranial cavity: contains the brain
- Thoracic cavity: contains the lungs, heart, and major blood vessels
- Abdominal cavity: contains the digestive organs
- Pelvic cavity: contains the reproductive organs
Tissue Types
- Epithelial tissue: forms the lining of organs, glands, and body surfaces
- Connective tissue: supports and connects other tissues
- Muscle tissue: allows for movement and contraction
- Nervous tissue: transmits and interprets signals
Organ Systems
- Nervous System: interprets and responds to stimuli
- Divided into Central Nervous System (brain, spinal cord) and Peripheral Nervous System (nerves, ganglia)
- Circulatory System: transports oxygen, nutrients, and waste products
- Heart pumps blood through arteries, veins, and capillaries
- Respiratory System: exchanges oxygen and carbon dioxide
- Lungs facilitate gas exchange, with trachea, bronchi, and diaphragm aiding breathing
- Digestive System: breaks down and absorbs nutrients
- Involves mechanical and chemical digestion in the mouth, stomach, and small intestine
- Absorbs nutrients in the small intestine and absorbs water in the large intestine
- Endocrine System: produces and regulates hormones
- Includes glands such as pituitary, thyroid, adrenal, pancreas, etc.
- Integumentary System: protects the body from external damage
- Skin consists of epithelial tissue, sweat glands, and hair follicles
- Muscular System: moves the body and maintains posture
- Skeletal muscles enable voluntary movement, smooth muscles enable involuntary movement, and cardiac muscles control heart function
- Skeletal System: provides support, protection, and movement
- Comprises 206 bones in the adult human skeleton, with joints connecting bones
- Urinary System: filters waste and excess fluids from the blood
- Kidneys filter waste, ureters transport urine to the bladder, and the urethra eliminates urine
