Circulatory System
What organ pumps blood around your body?
The heart
Where does digestion begin?
The mouth
The digestive system breaks food down into nutrients. What system carries those nutrients around the body?
Circulatory system
The heart is an example of what?
An organ
What is the name of Mario's brother?
Luigi
What liquid travels around your body carrying oxygen and nutrients?
Blood
What organ uses acid and enzymes to help break down food?
The stomach
After nutrients are absorbed into the small intestine, where do they go?
Into the bloodstream
What is a group of similar cells working together called?
Tissue
What game features a character called Steve and a world made entirely of blocks?
Minecraft
What are the three main types of blood vessels?
Arteries, veins and capillaries
Which organ absorbs most nutrients from digested food?
Small intestine
A muscle cell needs sugar and oxygen to release energy. Which two body systems help deliver these substances to the cell?
Digestive system provides sugar/nutrients and the respiratory system (lungs) provides oxygen; the circulatory system transports both.
Put these in order from smallest to largest:
Organ → Cell → Organ system → Tissue
Cell → Tissue → Organ → Organ system
What is the name of the blue Pokémon that evolves into Blastoise?
Squirtle
Which blood vessel carries blood AWAY from the heart?
Artery
What is the difference between mechanical and chemical digestion?
Mechanical digestion physically breaks food into smaller pieces, while chemical digestion uses chemicals/enzymes to break food molecules down.
Explain how a sandwich you eat can eventually provide energy to your leg muscles.
Food is digested → nutrients such as sugar are absorbed into the blood → blood transports them around the body → sugar reaches muscle cells → cells use it to release energy.
What could happen if a person's heart could no longer pump blood effectively?
The body's cells would receive less oxygen and nutrients, and waste products such as carbon dioxide would not be transported away as effectively.
In Inside Out, what emotion is represented by the colour blue?
Sadness
Why are capillaries so small and thin?
They allow substances such as oxygen, carbon dioxide and nutrients to move between the blood and body tissues.
Why can't your body simply absorb a piece of bread directly into your bloodstream?
The molecules in food are too large. Digestion breaks them into smaller molecules that can be absorbed.
Imagine the small intestine stops absorbing nutrients properly. Predict what might happen to the circulatory system and the rest of the body.
Fewer nutrients would enter the bloodstream, so cells throughout the body would receive less of the nutrients they need for energy, growth and repair.
A person has a blockage in one of their arteries. Explain why this could be dangerous for their cells.
Less blood may reach tissues beyond the blockage, meaning cells may receive less oxygen and nutrients and have difficulty removing wastes.
What is the only Australian state that is also the name of a country?
None!
