Complete Solutions
atoms - ANS one element; building blocks of matter
molecules - ANS two or more atoms joined together
Macromolecules - ANS A very large organic molecule composed of many smaller
molecules. includes proteins and DNA molecules; also form organelles
cellular level - ANS cells
tissue level - ANS tissues; group of similar cells that perform common functions
epithelial tissue - ANS covers exposed surfaces and lines body cavities
connective tissue - ANS protects, supports, and binds structures and organs
muscle tissues - ANS specialized for contraction, which brings about movement
nervous tissue - ANS conducts nerve impulses
organ level - ANS composed of organs; contains two or more tissue types
organ system level - ANS organs that work closely together
organismal level - ANS the human organism is made up of many organ systems
, integumentary system - ANS consists of the skin, mucous membranes, hair, and nail ; providers
protection, prevents water loss and gain, regulates body temp, and releases secretions
sketal system - ANS consists of skull, sternum, rib, cartilage, upper and lower limb bones, and
knee joints; provides support/ protection, blood cell production, stores calcium and
phosphorus, provide sight for ligament and muscle attachments
Muscular System - ANS consists of tendons, pectoral muscle, aponeurosis, sartarious
muscle; produces body movement, generates heat when muscles contract
nervous system - ANS consists of eye, brain, spinal cord, and nerves; responds to sensory
stimuli, controls muscles and some glands, and is responsible for consciousness,
intelligence, and memory
endocrine system - ANS consists of thyroid gland, thymus, adrenal glands, pancreas, kidney, and
testes; maintains homeostasis of blood composition and volume, controls digestive
processes/reproductive functions
cardiovascular system - ANS consists of the heart, blood, and blood vessels; heart moves blood
through blood vessels in order to distribute hormones, nutrient, gases, and pick up waste
products
lympathic system - ANS consists of tonsils, lymph nodes, thymus, thoracic duct, spleen,
and other lymph nodes; transports nutrients and filters lymph fluids that are collected and
transported and may participate in an immune response
respiratory system - ANS consists of nasal cavity, nose, trachea, bronchi, lungs, pharynx
(throat), and larynx (voice box); responsible for exchange of gases (oxygen and carbon dioxide)
between blood and the air in the lungs.
urinary system - ANS kidneys, ureters, urinary bladder, urethra. Eliminates nitrogenous
wastes from the body. Regulates water, electrolyte and acid-base balance of the blood.
