ASTHMA & BREATHING
What happens to the airways during an asthma attack?
They swell and become narrow.
What is anemia?
A condition where the body has fewer red blood cells than normal.
What does insulin do?
It unlocks cells so glucose can enter.
What does the pancreas normally make?
Digestive enzymes.
Which two conditions involve problems getting oxygen to the body’s cells?
Asthma and anemia.
Why do people with asthma sometimes feel tired or weak during an attack?
Less oxygen reaches the blood and cells.
Why do people with anemia feel weak or faint?
Cells don’t get enough oxygen.
What happens to glucose when the body doesn’t make enough insulin?
It stays in the blood instead of entering cells.
What do enzymes do?
Break food into small molecules the body can use.
Which two conditions lead to cells not getting enough glucose?
Diabetes and pancreas injury.
What sound is made when air moves through tight airways?
Wheezing.
What nutrient does the body need to make red blood cells?
Iron.
Where does glucose come from?
Carbohydrates that the digestive system breaks down.
What happens when the pancreas is injured and can’t make enough enzymes?
Food doesn’t break down properly and nutrients don’t enter the blood.
What system moves oxygen, glucose, insulin, and nutrients around the body?
The circulatory system.
Which two body systems work together to bring oxygen to cells?
The respiratory system and circulatory system.
Which structures in the lungs move oxygen into the blood?
Alveoli.
What is the main difference between Type 1 and Type 2 diabetes?
Type 1: no insulin made.
Type 2: insulin is made but not used well.
Why might someone with a pancreas injury feel tired?
Cells don’t get enough glucose for energy.
Which condition is helped by insulin made in a lab, and which is helped by enzymes made in a lab?
Diabetes → insulin
Pancreas injury → enzymes
How does an inhaler help someone during an asthma attack?
It opens the airways so more air can enter the lungs.
List two iron-rich foods that help prevent anemia.
Beans, meat, spinach, leafy greens (any two)
Why is high blood glucose dangerous?
Cells can’t get glucose, so they can’t make energy.
How do people with chronic pancreas injury stay healthy?
They take enzyme medicines made in a lab to help digest food.
Explain one similarity between asthma and diabetes.
Both prevent cells from getting the energy they need (asthma → low oxygen, diabetes → low glucose).
