4.2 Organs, tissues and cells

Learning goals

• You can recognize organsystems, organs, tissues and cells and you can describe their characteristics and functions
• You can explain in (parts of) organisms what the connection is between form and function 

Do you remember the name and function of these organs?

Number 20 is part of which organsystem?

The kidneys are part of the excretory system

Tissues

4.2

Function?!?

Intercellular material (" Tussencelstof") 

Cells rarely touch due to an amount of extracellular material between cells

Functions include: support (bone cells, cell walls), flexibility (cartilage) , transport of materials and signals, storage and protection

Many diverse forms: gel, liquid, fibrous or solid

Capacity for regeneration and repair

Form and function

In organisms there is a connection between the form and the function of the biological units that they are build of e.g. streamline, withstanding forces, axons and dendrites of neurons...

Homologie of analogie?

Vorm en functie
