Tissues, organs and organ systems
LO: Be able to identify, describe
and explain the role of human
tissues, organs and organ systems
1. What type of life existed before multi
cellular life on earth?Single celled
organisms
2. Name 3 systems that allow people or
goods to move around the country. Rail
network, road network, aviation,
canals, bus network etc.
3. List as many organelles of an animal
cell as you can. Nucleus, cell
membrane, cytoplasm, mitochondria,
ribosomes.
How do you get from single cells to
multicellular organisms?

Organs in a plant:
• What are the organs in a plant?
• What is their roles?
Guiding game:
• You have to get in pairs.
• You have a time limit.
• One person from each pair faces the back of the room
with their partner in front of them looking at the board.
• The person facing the board has to describe the picture
to their partner who will draw it.
• Best picture receives a prize.

Examples of tissues you need to know:
• A stomach has several tissues; including:
1. Muscular; contract and churn the contents.
2. Glandular; secretes enzymes & hormones
3. Epithelial; covers parts of the body
eg lining of stomach.
There are others e.g. connective tissue, nervous
tissue.

• The human body has many organ systems for
exchanging and transporting materials, for example,
the excretory system, and the digestive system.
(of course it is more complex that this but let’s break it down to easy to remember steps)

Organs
• The digestive system –is made of
different cells that form tissues
that work together
1. Glands eg pancreas and salivary,
make digestive juices
2. Stomach and small intestine;
digest food
3. Liver produces bile; to emulsify
fats
4. Small intestine; lined with
microvilli for increased
absorbtion of small soluble food
molecules
5. The large intestine; absorbs
excess water and leaves faeces
