What is mitosis used for?
Growth, repair, or asexual reproduction
Name a benefit of being a bionic human
Answer depends, some examples; enhanced strength, less prone to disease
Explain the role of the excretory system
To remove excess waste product from the human body
What is the main purpose of body systems working together?
To keep the body running, to maintain stable health, to ensure growth, reproduction and survival

Name 1 way the skeletal/muscular system helps the digestive system

How does mitosis help repair a wound?
Creating more cells to replace the damaged ones
Which intestine helps absorb the nutrients from food in the digestive system?
Small intestine
Explain how the circulatory and respiratory system work together
Supply the body with oxygen and remove carbon dioxide. Oxygen is carried through the blood to the body and blood carries carbon dioxide to lungs to be exhaled.
Describe what happens when the respiratory and circulatory system fails
The body does not get enough oxygen and carbon dioxide builds up in the blood, causing difficulty breathing and damage to organs
Describe what happens when mitosis goes uncontrollable
Cells divide rapidly, damaging tissue around them, forming tumours that can potentially spread and cause cancer

How much percentage of deaths are caused by the failure of multiple body systems?
50%
Name the 6 phases of mitosis
