How We Get The Energy We Need Flashcards
How do we get glucose?
From the food we eat
Respiration is a….
Chemical reaction which involves real ease of energy from food
Where does it occur?
In all living cells
What is energy measure in?
Joules
What is the human body made up of?
Several different organ systems
What do each organ system do?
Their own particular jobs but all systems work together
What does respiration mean?
How we get the energy we need
The cells use glucose and oxygen to….
Release energy
What are the waste products?
Carbon dioxide and water
What does aerobic mean?
Using oxygen/ in the presence of oxygen
What is the aerobic respiration equation?
Glucose + oxygen ➤ carbon dioxide + water + energy
Why is the digestive system important?
Changes large insoluble food molecules to small soluble ones to be absorbed into blood stream
Why is the circulatory system important?
carries small soluble food molecules and oxygen to every cell in body and takes away unwanted waste
Why is the respiratory system important?
oxygen is taken into bodies via lungs and carbon dioxide is removed, oxygen is then absorbed into blood, travels to heart and is then pumped around rest of body
Why do we need energy?
