Study Notes
Human Body Systems
- The human body is comprised of various systems working together
- These include nervous, integumentary, circulatory, endocrine, respiratory, digestive, reproductive, urinary, muscular, and skeletal systems
Infrastructure Systems
- Circulatory: Transports blood, nutrients, and gases throughout the body (heart, blood vessels, blood)
- Muscular: Enables movement and provides body structure (muscles, tendons)
- Nervous: Controls bodily functions and responds to stimuli (brain, spinal cord, nerves)
- Skeletal: Supports and protects the body, stores minerals, and produces blood cells (bones, joints)
Regulation Systems
- Endocrine: Regulates bodily functions like growth, metabolism, and mood (hormones, glands)
- Lymphatic: Protects the body from infection and maintains fluid balance (lymph, lymph nodes, spleen)
- Urinary: Removes waste and excess fluid from the body (kidneys, bladder, urethra)
Energy Systems
- Respiratory: Takes in oxygen and removes carbon dioxide (lungs, airways)
- Digestive: Breaks down food into nutrients and absorbs them (stomach, intestines, liver)
Reproductive Systems
- Reproductive: Produces offspring and allows for sexual reproduction (ovaries, testes, uterus)
Digestive System
- Mechanical Digestion: Physically breaks down food
- Chemical Digestion: Breaks down food into absorbable molecules
- Organs: Mouth, esophagus, stomach, small intestine, large intestine, pancreas, liver, gallbladder
- Processes: Ingestion, Digestion, Absorption, Egestion
Excretory System
- Functions: Eliminates cellular wastes through lungs, skin, kidneys, and digestive system
- Processes: Sweating, exhaling, urination, defecation
- Parts: Kidneys, ureters, bladder, urethra
Respiratory System
- Components: Nasal cavity, mouth, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, lungs, diaphragm
- Functions: Takes in oxygen and releases carbon dioxide
- Processes: Inhalation, exhalation
- Gas Exchange: Occurs in the alveoli
Circulatory System
- Components: Heart, blood vessels (arteries, capillaries, veins), blood
- Functions: Transports nutrients, oxygen, hormones, wastes, and other materials throughout the body, fights infections, maintains body temperature (thermoregulation), and maintains fluid balance
- Blood Composition: Plasma, red blood cells, white blood cells, platelets
- Blood Vessels: Arteries carry blood away from the heart, veins carry blood to the heart and capillaries facilitate exchange between blood and tissues.
Heart
- Chambers: 4 chambers (2 atria and 2 ventricles)
- Circulation: Pulmonary circulation (heart to lungs and back) and systemic circulation (heart to body and back)
