Study Notes
Introduction to the Human Body
- Physiology studies the functions of living organisms
- Anatomy studies the structure of an organism and its parts
- Organization is a key characteristic of the human body
Structural Levels of the Body
- The body is made up of smaller units
- Chemical level is the simplest - Atoms are the smallest units of matter
- Cells are the smallest structural units of living things
- Tissues are groups of similar cells with a common function
- Organs are made of various tissue types, performing specific functions
- Systems are combinations of organs working together
Introduction to Body Systems
- The human body has 11 systems, each with specific functions
Digestive System
- Breaks down food and absorbs nutrients
- Includes mouth, pharynx, esophagus, stomach, small intestine, large intestine, liver, and pancreas
Muscular System
- Provides movement through skeletal, cardiac, and smooth muscles
- Skeletal muscles are voluntary (conscious control)
- Cardiac muscles are involuntary (automatic heart contractions)
- Smooth muscles are involuntary (control other organs)
Integumentary System
- Includes skin, providing sensory receptors and protection
- Also includes hair, nails that provide protection
Excretory/Urinary System
- Removes waste products and maintains fluid/electrolyte balance
- Major organs include kidneys, ureter, urinary bladder, and urethra
Reproductive System
- Enables continuation of life
- Combines male sperm and female egg to form a zygote
Circulatory System
- The heart pumps blood to distribute hormones, nutrients, gases, and removes waste
Respiratory System
- Provides oxygen and expels carbon dioxide
- Involves nasal passage, trachea, bronchial tubes, lungs, alveoli (tiny air sacs)
Skeletal System
- Provides structure and protection for internal organs
Immune System
- Protects against germs and microorganisms
- Composed of special cells, proteins, tissues, and organs
Nervous System
- Coordinates body actions through the brain, spinal cord, and nerves
- Also responsible for senses, consciousness, intelligence, and memory
Endocrine System
- Composed of hormones that control many bodily activities (like reproduction, growth, digestion)
