1. Ciliated Cell Structure:
They line all the air passages down to the lungs.
They have tiny hairs called cilia.
Function:
Designed to stop Lung Damage
Hairs sweep mucus with trapped dust and bacteria back up the throat to be swallowed.
If you smoke then the hairs die and the mucus builds up leading to the well known smoker’s cough
Nucleus
cilia

2. Egg Cell Egg (Ovum) Cell Structure:
Contains yolk that acts as a food source for the developing embryo (baby) when fertilised
Much larger than other animal cells (look at the size of the sperm next to it!)
Function:
Carries the mother’s DNA
Cytoplasm containing yolk
Layer of jelly
Nucleus

3. Red blood cells Red Blood Cells Structure: Large surface area
Contains hemoglobin which picks up oxygen
Found in plasma
Has no nucleus to make room for more oxygen
Function:
Carries oxygen from the lungs to the body and carbon dioxide from the body back to the lungs.

4. Nerve cells Neuron Cells Structure:
These are extremely elongated (long) cells
They have many branches at both ends to connect to other nerve cells
The long axis (main branch) is covered in fat to prevent the electrical impulses affecting the surrounding parts of your body
Function:
To carry nerve impulses around your body

5. Red blood cells White Blood Cells Function:
nucleus
Function:
These cells are found in your blood.
They are attracted to diseases and bacteria that enter your body
They then ‘eats’ any bacteria/disease so the microbe can’t infect you and make you ill

6. Sperm cells Sperm Cell Structure:
Have a long tail so they can swim to find an egg
There are enzymes in the head of the sperm to help the sperm get into the egg
Function:
To carry the father’s genetic information (DNA) to the egg
