Animal Cells

Blood.....is made up of many differnt types of cells all with very important jobs. 
Red Blood cells

White Blood Cell

Has a nuclei but no heamoglobin

They are attracted to microbes that enter your body

They then engulf harmful microbes and some produce antibodies and/or antitoxins


For clotting blood and forming a mesh over an opening in skin to stop further blood loss

Red Blood Cells

Large surface area - Bi-concave disc shape

Contains haemoglobin which picks up oxygen

Has no nucleus to make room for more oxygen

Thin cell wall

Carries oxygen from the lungs to the body and carbon dioxide from the body back to the lungs

A Nerve Cell
Nerve Cells


These are extremely long cells 

They have many branches at both ends to connect to other nerve cells

The long axis (main branch) is covered in myelin sheath for faster conduction

To carry nerve impulses around your body

Sperm Cell
Sperm Cell

Have a long tail so they can swim to find an egg

There are enzymes in the head of the sperm (acrosome) to help the sperm get into the egg

Many mitochondria

Function: To carry the father’s genetic information (DNA) to the egg

Human Egg Cell
Egg Cell

Contains yolk that acts as a food source for the developing embryo (baby) when fertilised
Much larger than other animal cells 
Many mitochondria

Function: Carries the mother’s DNA

Ciliated epithelial cells
Cilliated Cells

They line all the air passages down to the lungs.
Also in oviduct
They have tiny hairs called cilia.
Designed to stop lung damage
Hairs sweep mucus with trapped dust and bacteria back up the throat to be swallowed.
