LET'S DISCUSS ORGAN TRANSPLANTS

• Do you think the opt-out system will increase the number of donors?
• To you think it is a good thing that we now have an opt-out system instead of an opt-in system? Why?

Today we will discuss tissues

Learning goals 1.2 

• You can describe and explain the following terms: tissue, cell, functional cell & functional tissue.  
• You can name the 4 tissue types and recognize them in a picture. 
• You can describe the functions of the 4 tissue types. 
• You can describe the difference between a single-celled organism and a multicellular organism. 

Epithelial tissue

Cells that provide a covering (on the skin or surfaces inside your body, like lungs or intestines) 

Muscle tissue

Muscle cells that can contract. 

Found in your muscles, but also in your heart 

and in your organs. 

Connective tissue

Supports other tissues and binds them together. 

Found in your bones and blood. 

Nerve tissue

Made from nerve cells that send and receive messages

Found in your brain, spinal cord & nerves 

Which organ system is made up of nerve tissue?

Answer the following questions:

• What is the difference between the 4 tissue types and functional tissues? 

• Do single-celled organisms also have tissues? Explain your answer. 

DONE? Start with the SIF & PIF on 1.2 and study the learning goals for 2.4 (this is homework for next week)
