8b: Respiration

respiration
1. happens in all the cells in your body
2. happens in your lungs
3. happens in your small intestine
4. makes oxygen
Respiration:
1. glucose + oxygen --> carbon dioxide + water + energy
2. glucose + water --> carbon dioxide + oxygen + energy
3. water + oxygen --> carbon dioxide + glucose + energy
4. glucose + oxygen + energy --> carbon dioxide + water
Which is the correct order? Most energy <------------> Least energy:
1. carbohydrates - fats - proteins - vitamins & minerals
2. fats - proteins - carbohydrates - vitamins & minerals
3. proteins - carbohydrates - fats - vitamins & minerals
4. vitamins & minerals - carbohydrates - fats - proteins
when you breathe in
1. your ribs move up & your diaphragm flattens
2. your ribs move up and your diaphragm "domes" upwards

4. your ribs move down and your diaphragm "domes" upwards
when you breathe out
1. your ribs move down and your diaphragm "domes" upwards
2. your ribs move up & your diaphragm flattens
3. your ribs move up and your diaphragm "domes" upwards
4. your ribs move down and your diaphragm flattens

the air we breathe out contains
1. more carbon dioxide, less oxygen, more moisture
2. less carbon dioxide, more oxygen, less moisture
3. less carbon dioxide, less oxygen, less moisture

alveoli are
1. air sacs in the lungs
2. tubes in the lungs

the kidneys
1. remove waste from the blood
2. remove oxygen from the blood
3. add oxygen to the blood
4. absorb nutrients from the blood
arteries
1. have thick walls
2. have thin walls
3. have muscles in the walls
4. are tiny tubes
veins
1. have muscles in the walls
2. have very thick walls
3. are tiny tubes
4. carry oxygenated blood
the left side of the heart
1. is larger, to pump blood around the whole body
2. is smaller, to pump blood only to the lungs
3. is larger, to pump blood to the lungs
4. is the same size as the right side
Doctors can listen to your heartbeat using a
1. stethoscope
2. oscilloscope
3. microscope
4. epidiascope
You can feel your pulse on
1. an artery
2. a vein
3. a capillary
4. a muscle
the heart muscles are supplied with oxygenated blood from the
1. coronary arteries
2. pulmonary artery
3. carotid artery
4. cervical artery
respiration
1. happens in plants and animals
2. happens in plants only
3. happens in animals only
4. happens in plants, but only at night
we can detect carbon dioxide using

3. benedict's solution
4. universal indicator
your diaphragm is
1. a sheet of muscle below your lungs
2. a membrane in your throat
3. part of the circulatory system
4. the lining of your lungs
oxygen in the blood is carried by
1. red blood cells
2. white blood cells
3. platelets
4. plasma
in the blood, platelets
1. help blood to clot if you are injured
2. carry oxygen
3. fight invading bacteria
4. carry carbon dioxide
in the blood, plasma
1. carries dissolved carbon dioxide
2. carries oxygen
3. fights invading bacteria
4. helps blood to clot if you are injured
the main blood groups are
1. O, A, B, AB
2. A, B, AB, C
3. O, A, B
4. A,B, O, OB
in your body, valves are found in
1. heart and veins
2. heart
3. heart and arteries
4. heart and capillaries
oxygen in the blood is carried by
1. haemoglobin in the red blood cells
2. chlorophyll in the red blood cells
3. haemoglobin in the white blood cells
4. platelets
alveoli
1. have a large surface area and a good blood supply
2. have thick walls
3. clean the air in your lungs
4. are tubes leading to the air sacs in your lungs
lime water
1. turns milky in the presence of carbon dioxide
2. turns milky in the presence of oxygen
3. turns red in the presence of carbon dioxide
4. turns red in the presence of oxygen
capillaries
1. have very thin walls
2. have thick walls
3. have muscles in the walls
4. have valves to stop the blood flowing the wrong way
which of these is true?

2. carbon monoxide is a waste product of respiration
3. respiration produces oxygen gas
4. exercise increases the risk of heart disease
