Question types: Match the organ system

Rule: Human organ systems

Digestive: stomach, intestines, liver. Respiratory: windpipe, lungs. Circulatory: heart, blood vessels, blood.

Nervous: brain, spinal cord, nerves. Excretory: kidneys, bladder. Skeletal and muscular: bones, muscles.

Example: The kidneys clean the blood and make urine: they belong to the excretory system.

Watch out: The liver is not part of the circulatory system but the digestive one: it makes bile to help digest fat.

Sample questions

  1. Question 1 Easy

    Which organ system does this organ belong to? Match each item (1–3) with the right option (A–D).

    1. spinal cord
    2. liver
    3. biceps
    • A) muscular system
    • B) digestive system
    • C) skeletal system
    • D) nervous system
    Show the solution
    Answer:
    1. spinal cord → D) nervous system
    2. liver → B) digestive system
    3. biceps → A) muscular system

    How it works: spinal cord – nervous system; liver – digestive system; biceps – muscular system

  2. Question 2 Normal

    Which organ system does this organ belong to? Match each item (1–4) with the right option (A–E).

    1. spinal cord
    2. liver
    3. biceps
    4. skull
    • A) urinary system
    • B) nervous system
    • C) muscular system
    • D) skeletal system
    • E) digestive system
    Show the solution
    Answer:
    1. spinal cord → B) nervous system
    2. liver → E) digestive system
    3. biceps → C) muscular system
    4. skull → D) skeletal system

    How it works: spinal cord – nervous system; liver – digestive system; biceps – muscular system; skull – skeletal system

  3. Question 3 Hard

    Which organ system does this organ belong to? Match each item (1–5) with the right option (A–F).

    1. spinal cord
    2. liver
    3. biceps
    4. skull
    5. kidneys
    • A) skeletal system
    • B) digestive system
    • C) muscular system
    • D) nervous system
    • E) urinary system
    • F) circulatory system
    Show the solution
    Answer:
    1. spinal cord → D) nervous system
    2. liver → B) digestive system
    3. biceps → C) muscular system
    4. skull → A) skeletal system
    5. kidneys → E) urinary system

    How it works: spinal cord – nervous system; liver – digestive system; biceps – muscular system; skull – skeletal system; kidneys – urinary system
