Question types: Fill in the gaps

Rule: The human body

The heart pumps blood round the whole body. In the lungs the blood takes in oxygen and gives off carbon dioxide.

The brain controls the body. The stomach and intestines digest food. The skeleton supports the body, muscles move it.

Arteries carry blood away from the heart, veins carry it back to the heart.

Example: The path of food: mouth → gullet → stomach → small intestine → large intestine.

Watch out: Air doesn’t go to the stomach: it goes through the nose and windpipe to the lungs, food goes down the gullet.

Sample questions

  1. Question 1 Easy

    Fill in the right words.

    1. The longest bone in the human body is the …. (thigh bone (femur) / shin bone / upper arm bone)
    2. Blood picks up oxygen in the …. (liver / kidneys / lungs)
    3. White blood cells protect the body against …. (cold / light / infection)
    Show the solution
    Answer:
    1. The longest bone in the human body is the thigh bone (femur).
    2. Blood picks up oxygen in the lungs.
    3. White blood cells protect the body against infection.

    How it works: The longest bone in the human body is the thigh bone (femur). Blood picks up oxygen in the lungs. White blood cells protect the body against infection.

  2. Question 2 Normal

    Fill in the right words.

    1. Most nutrients are absorbed in the … intestine. (blind / large / small)
    2. The largest organ of the human body is the …. (skin / heart / brain)
    3. An adult skeleton has about … bones. (306 / 106 / 206)
    4. Insulin is made by the …. (spleen / thyroid gland / pancreas)
    Show the solution
    Answer:
    1. Most nutrients are absorbed in the small intestine.
    2. The largest organ of the human body is the skin.
    3. An adult skeleton has about 206 bones.
    4. Insulin is made by the pancreas.

    How it works: Most nutrients are absorbed in the small intestine. The largest organ of the human body is the skin. An adult skeleton has about 206 bones. Insulin is made by the pancreas.

  3. Question 3 Hard

    Fill in the right words.

    1. The digestion of starch begins in the …. (rectum / mouth / large intestine)
    2. Platelets help the blood to …. (take in oxygen / clot / filter)
    3. Blood low in oxygen flows back to the heart in the …. (arteries / veins / capillaries)
    4. The light-sensitive cells of the eye are in the …. (retina / cornea / lens)
    Show the solution
    Answer:
    1. The digestion of starch begins in the mouth.
    2. Platelets help the blood to clot.
    3. Blood low in oxygen flows back to the heart in the veins.
    4. The light-sensitive cells of the eye are in the retina.

    How it works: The digestion of starch begins in the mouth. Platelets help the blood to clot. Blood low in oxygen flows back to the heart in the veins. The light-sensitive cells of the eye are in the retina.
