IN THIS POWER POINT PRESENTATION WE TELL ABOUT VARIOUS ORGAN SYSTEM OF HUMAN BODY

1. Cells, tissues, organs and systems
Friday, 26 April 2024
Learning objectives:
• To order structures to show how living
organisms are organised in terms of cells,
tissues, organs and systems.

2. • A cell living on its own is called unicellular
• Many cells together in an organism is called
multicellular

3. • 7E – Chicken leg dissection Tues 18th

4. Starter (5 mins)
• Brick wall house street town
• Discuss in pairs how these words relate to one
another.
• Read through the information on Student’s
Book page 13 and discuss how this 'town
model' is similar to a living organism.

5. Living things are made up of organised systems.
Each specific cell is grouped with cells similar in
structure and function to form a tissue.
How is the body organised?

How is the body organized?
Living things are made up of organized systems too.
Each specific cell is grouped with other cells similar in structure and function to
form tissues and ultimately organs:
Groups of tissues work
together to form
organs.
Groups of cells work
together to form
tissues.
Cells are the
basic units of
life.
cell tissue organ

7. • Animal cells and plant cells can form
tissues.
• A living tissue is made from a group of
cells with a similar structure and function,
which all work together to do a particular
job. Here are some examples of tissues:
• muscle
• the lining of the intestine
• the lining of the lungs

8. Animal tissues Plant tissues
muscle
bone
liver
skin
lung
mesophyll
phloem
xylem
Can you think of any more types of tissue?

How is the body like a school?
To understand how the body is organized, think about all the different people that
work in a school to make it function.
Everybody in the school needs to know where they should be and what they are
doing for the school to function properly.
Everybody does a different job – they have different skills and equipment to
help them do their job.
 teachers and teaching assistants
 caretakers and cleaners
 dinner ladies and bus drivers
 governors and office workers

What is a system?

Why be organized?
Why do organisms have to be so organized?
Organization of the body allows complex organisms to carry out many
different jobs at the same time.
Being organized means that the body does not waste energy, so it is
more efficient.
body life
processes
excretion
nutrition
respiration
growth reproduction
sensitivity
movement

13. The body is made up of different organ systems working
together to carry out all the functions of a living organism.
Both the body and schools are organized systems:
cell pupil
tissue registration group
organ subject class
organ system year
organism school

19. Main 50 mins
• Look at keywords – do you all undertand meanings?
• Students complete the questions on page 13 of the Student’s Book.
• Students then work in pairs to complete the activity on Worksheet
Lesson 6: Cells, tissues, organs and systems. They organise the cards
first into examples of cells, tissues, organs, organ systems
and organisms. They then use the cards to order groups of five to
show the progression from cell
to organism.
• Ask pairs for feedback on how they ordered the cards and check
understanding. Choose one example, such as neurone (cell), nerve
(tissue), brain (organ), nervous system (organ system) and draw a
'pyramid of numbers’ style diagram to illustrate how the numbers
at each level decrease.
