Quick match – organ systems and life processes
Organ systems and their function
Task 1
1)
Cut out the organ systems on the right and match them to their functions on the left.
maintenance
reproductive system
replacement
sensory system
movement
circulatory system
support
respiratory system
supply and removal
digestive system
absorption
excretory system
response
nervous system
transport
muscular system
communication
2)
skeletal system
Some organ systems have more than one function. Add other words to the function boxes
to summarise what each organ system does.

Quick match – organ systems and life processes
Life processes and organ systems
A living thing can be defined as carrying out seven processes.
The mnemonic MRS GREN is a useful memory aid.
Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition
Task 2
1)
Can you assign organ systems to each process? Some may have more than one.
Organ systems:
skeletal, reproductive, sensory, nervous, excretory, respiratory, digestive,
circulatory, muscular.
Processes of living things
Organ system/s involved in life process
Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition
2)
Which system is missing from this list?
It is particularly concerned with growth and changes in the body.
Here are two anagrams to help you:
moorhens
inner code

Quick match – organ systems and life processes
Teaching notes
This activity looks at organ systems, their functions and how they link to the life processes of living
things.
This task could lead to a discussion about how simple organisms carry out the seven life processes
and why it was necessary for organ systems to evolve.
The two sheets could be used together or separately.
Answers
Organs and organ systems
Task 1
replacement – reproductive
response – sensory
transportation – circulatory
supply and removal – respiratory
absorption – digestive
maintenance – excretory
communication – nervous
movement – muscular
support – skeletal
Life processes and organ systems
Task 2
The answers are certainly open to discussion!
1)
Movement – muscular, skeletal, nervous
Respiration – respiratory, digestive, circulatory, excretory
Sensitivity – sensory, nervous
Growth – ?
Reproduction – reproductive
Excretion – excretory, digestive
Nutrition – digestive, respiratory
2)
The missing organ system is the endocrine system.
Anagram solutions:
moorhens = hormones
inner code = endocrine (system)
