Skeletal System
- Components: Bones, cartilage, ligaments, joints.
-
Functions:
- Provides structure and support.
- Protects vital organs (e.g., skull protects the brain).
- Facilitates movement (muscle attachment).
- Produces blood cells (hematopoiesis) in bone marrow.
- Stores minerals (e.g., calcium, phosphorus).
Muscular System
- Components: Skeletal muscles, smooth muscles, cardiac muscle.
-
Functions:
- Enables movement of the body.
- Maintains posture.
- Produces heat through muscle contractions.
- Smooth muscles control involuntary functions (e.g., digestion).
Nervous System
- Components: Brain, spinal cord, nerves, sensory organs.
-
Functions:
- Controls voluntary and involuntary actions.
- Processes sensory information.
- Coordinates responses to stimuli.
- Facilitates communication between different body parts.
Endocrine System
- Components: Glands (e.g., pituitary, thyroid, adrenal), hormones.
-
Functions:
- Regulates metabolism, growth, and development.
- Controls mood and stress responses.
- Maintains homeostasis (e.g., blood sugar levels).
- Influences reproductive functions.
Cardiovascular System
- Components: Heart, blood vessels (arteries, veins, capillaries), blood.
-
Functions:
- Transports oxygen, nutrients, hormones, and waste products.
- Regulates body temperature and pH balance.
- Protects against disease through immune response.
Lymphatic System
- Components: Lymph nodes, lymphatic vessels, spleen, thymus, tonsils.
-
Functions:
- Maintains fluid balance by returning interstitial fluid to the bloodstream.
- Absorbs fats and fat-soluble vitamins from the digestive system.
- Provides immune defense against pathogens.
Respiratory System
- Components: Nose, pharynx, larynx, trachea, bronchi, lungs, diaphragm.
-
Functions:
- Facilitates gas exchange (oxygen intake, carbon dioxide removal).
- Helps regulate blood pH through carbon dioxide levels.
- Filters, warms, and humidifies incoming air.
Digestive System
- Components: Mouth, esophagus, stomach, intestines (small and large), liver, pancreas, gallbladder.
-
Functions:
- Breaks down food into nutrients for absorption.
- Eliminates waste products from the body.
- Produces enzymes and digestive juices for digestion.
Urinary System
- Components: Kidneys, ureters, bladder, urethra.
-
Functions:
- Removes waste products and excess substances from the blood.
- Regulates water and electrolyte balance.
- Maintains blood pressure and pH balance.
Integumentary System
- Composed of skin, hair, nails, and glands that serve as the body's barrier.
- Protects against pathogens, injury, and dehydration while providing thermal insulation.
- Regulates body temperature through sweat and blood flow adjustments.
- Synthesizes vitamin D, essential for bone health, through exposure to sunlight.
- Facilitates sensory reception, allowing detection of touch, pain, and temperature changes.
Skeletal System
- Includes bones, cartilage, ligaments, and joints, forming the body's framework.
- Provides structural support, allowing for upright posture and shape.
- Protects vital organs; for instance, the skull encapsulates the brain.
- Facilitates movement by serving as attachment points for muscles.
- Produces blood cells in the bone marrow, essential for oxygen transport.
- Stores minerals, primarily calcium and phosphorus, crucial for bodily functions.
Muscular System
- Comprises skeletal, smooth, and cardiac muscles responsible for various movements.
- Enables voluntary body movement, including all physical actions.
- Maintains posture by stabilizing joints and body alignment.
- Produces heat through muscle contractions, contributing to thermoregulation.
- Smooth muscles manage involuntary functions such as digestion and blood vessel regulation.
Nervous System
- Encompasses the brain, spinal cord, nerves, and sensory organs that relay signals.
- Controls both voluntary and involuntary actions for precise body function.
- Processes sensory information, allowing perception of the environment.
- Coordinates quick responses to stimuli through reflex actions.
- Facilitates communication between different body parts for cohesive operation.
Endocrine System
- Comprised of hormone-secreting glands like the pituitary, thyroid, and adrenal glands.
- Regulates metabolism, growth, and development through hormonal signals.
- Influences emotional states and stress responses to maintain mental well-being.
- Ensures homeostasis, such as regulating blood sugar and water levels.
- Affects reproductive health by controlling sexual function and development.
Cardiovascular System
- Made up of the heart, blood vessels (arteries, veins, capillaries), and blood.
- Transports oxygen and nutrients to tissues while removing carbon dioxide and waste.
- Regulates body temperature and pH balance to maintain stable internal conditions.
- Provides immune defense through the circulation of disease-fighting cells and antibodies.
Lymphatic System
- Composed of lymph nodes, lymphatic vessels, spleen, thymus, and tonsils.
- Maintains fluid balance by returning interstitial fluid to the bloodstream.
- Absorbs fats and fat-soluble vitamins from the digestive tract for energy storage.
- Provides immune defense, aiding in the detection and destruction of pathogens.
Respiratory System
- Includes the nose, pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
- Facilitates gas exchange critical for oxygen intake and carbon dioxide elimination.
- Helps regulate blood pH by managing carbon dioxide levels in the bloodstream.
- Filters, warms, and humidifies air before it reaches the lungs, ensuring optimal breathing conditions.
Digestive System
- Made up of the mouth, esophagus, stomach, intestines, liver, pancreas, and gallbladder.
- Breaks down food into essential nutrients for cellular absorption and utilization.
- Eliminates waste products, maintaining overall bodily health and function.
- Produces enzymes and digestive juices necessary for effective digestion and nutrient assimilation.
Urinary System
- Composed of kidneys, ureters, bladder, and urethra, which manage waste excretion.
- Removes waste products and excess substances from the bloodstream efficiently.
- Regulates water and electrolyte balance to prevent dehydration and maintain homeostasis.
- Helps maintain blood pressure and pH balance, essential for preventing metabolic disturbances.
