Human Body Flashcards
six structural levels that our body can be studied
chemical, cell, tissue, organ, organ system and organism.
deals with how different atoms like hydrogen and carbon interact to form molecules.
The Chemical Level
which is the basic unit of organisms, we try to correlate how a molecular substance affects a living organism.
The Cell Level
are combined cells that are similar. Their similarity in characteristics and surrounding materials determines its functions.
The Tissue Level
When two or more tissue types work together to perform one or more functions
Organ
Different tissues combine to form organs, such as the
urinary bladder.
Organ Level
This pertains to group of organs working together to sustain a specific function.
Organ System Level
Provides protection, regulates temperature,
prevents water loss, and helps produce vitamin D. Consists of skin, hair, nails, and sweat glands.
Integumentary System
Provides protection and support, allows body
movements, produces blood cells, and stores minerals and adipose tissues. Consists of bones, associated cartillages, ligaments and joints.
Skeletal System
Produces body movements, maintains posture,
and produces body heat. Consists of muscles attached to the skeleton by tendons.
Muscular System
Removes foreign substances from the blood
and lymph, combats disease, maintains tissue fluid balance, and absorbs dietary fats from the digestive tract. Consists of the lympathic vessels, lymph nodes, and other lymphatic organs.
Lymphatic System
Exchanges oxygen and carbon dioxide
between the blood and air and regulates the blood pH. Consist of the lungs and respiratory ligaments.
Respiratory System
Performs the mechanical and chemical
processes of digestion, absorption of nutrients, and elimination of wastes. Consists of the mouth, esophagus, stomach, intestines, and accessory organs.
Digestive System
A major regulatory system that defects
sensations and controls movements, psychological processes, and intellectual functions. Consists of the brain, spinal cord, nerves, and sensory receptors.
Nervous System
A major regulatory system that influences
metabolism, growth, reproduction and many other functions. Consists of glands, such as the pituitary, that secret hormones.
Endocrine System
