Life Cycle - Human Biology (5A)
Pre Lab 

  • Comparing functions of specific body systems.
  • Defining the organs of body systems.
  • circulatory
  • digestive
  • endocrine
  • excretory
  • integumentary
  • muscular
  • nervous
  • reproductive
  • respiratory
  • skeletal

Students use a worksheet to review the different body systems.



The human body is composed of interactive systems. Most organs in the body are necessary, a few like tonsils are not.  There are specific functions for each of the organs in the systems, but they cannot operate by themselves.

Below is a chart that will help you review the different systems with your students.




respiratory lungs, nasal passages,   bronchi, pharynx, trachea, diaphragm, bronchial tubes intake of oxygen and removal of carbon dioxide from body
nervous  spinal cord, brain, nerves, skin, eyes, ears, tongue, nose control of body activities and the reaction to stimuli
digestive stomach, liver, teeth, tongue, pancreas, intestine, esophagus break down of food and absorption for use as energy
excretory kidneys, bladder ureters, skin controls water and salt balance
 endocrine pituitary gland, adrenal gland, thyroid gland, gonads production of hormones and body regulation
skeletal and muscular bones, muscles protection and movement
circulatory blood, blood vessels, heart, lymph transport of nutrients, metabolic wastes, water, salts, and disease fighting cells
 integumentary skin protection of body from injury and bacteria, maintenance of tissue moisture, holds receptors for stimuli response, body heat regulation


  1.  Use the worksheet to have  students identify the different systems of the body.  
  2. Sing or read Skeletal Hip Hop with students.  Go over the integration of the vocabulary with the rhyme.  You may want students to try and create their own song or poem to go along with some the information they learned by comparing the different systems.  You may want to just do 2 or 4 lines and then make a class bone of the systems.
