Fill in the blank squares:
System
Major Structure(s)
Brain and Spinal Cord
Major Function
Integumentary System
Lungs
Breaks down food small
enough to be used by cells;
solid waste removal
Excretory system
Support; produces blood
cells
Muscles
Supplies different parts of
the body with nutrients and
oxygen
Endocrine system
Testes, penis, ovaries,
vagina
Lymphatic/Immune System
List the systems that work together to perform:
Nutrient Absorption:
Body System
Function it Performs to aid in Nutrient
Absorption
Protection and Defense against injury and illness:
Body System
Function it Performs to aid in defense against
injury and illness
Maintaining Homeostasis: (there are more than 4 right answers)
Body System
Function it Performs to aid in maintaining
homeostasis
Body Systems Matching
Directions: Match the system to its primary functions and also to the organs found in that system. Write the correct
letter(s) under the system name. Place the value (number found next to the letter(s)) next to the letters. The numbers will
add up to a 100 when all the correct answers are put together. Letters can be used more than once. Each system can have
more than one function and organ letter.
