Anatomy - studies the structure of the body
Physiology - studies the function of the body parts
Levels of organization - atom, molecule, organelle, cell, tissue, organ, organ system,
organism
cells - smallest unit of living things
tissues - a group of similar cells that have a common function
organ - structure composed of at least 2 tissue types that performs a specific function for
the body.
necessary life functions - maintaining boundaries, movement, responsiveness, growth,
digestion, excretion, reproduction, and metabolism
integumentary system - system composed of hair, skin and nails, covers external body and
protects deeper tissue
skeletal system - system composed of bones and joints, protects and supports, provides
bodys frame work for muscles
, muscular system - system composed of skeletal muscles and allows for movements and
manipulation of the environment
nervous system - composed of spinal cord, brain and nerves. control system of the body and
responds to changes by activating muscles and glands
endocrine system - Composed of glands that regulate the processes such as growth and
reproduction.
cardiovascular system - composed of heart and blood vessels, transports blood which carries
oxygen, CO2, nutrients and waste.
lymphatic system - composed of red bone marrow, nodes, spleen, vessles and thoracic duct,
which disposes debris in the lymphatic stream.
respiratory system - composed of nasal cavity, pharynx, larnx, trachea, broncus and lungs,
keeps blood supplied with O2 and removes CO2
digestive system - Composed of oral cavity, esophogus, liver, stomach, intestines and
rectum. breaks down food and absorbs nutrients
urinary system - Composed of kidneys, ureters, bladder and urethra, rids the body of acid-
based wastes.
reproductive system - System that functions in producing offspring
homeostasis - the ability to maintain an internal balance even when outside world changes.
dynamic state of equilibrium
receptor, control center, effector - 3 main parts of homeostatic control
