What Is An Organ System In Biology? - Quiz

A quiz designed to test the knowledge of students who have done some learning for NZQA Unit Standard. Demonstrate knowledge of the characteristics of living things, organs, and organ systems


Questions and Answers
  • 1. 

    The function of the DIGESTIVE SYSTEM is to....

    • A.

      Break down our food so that we can absorb (take in) the nutrients

    • B.

      Get oxygen into the blood

    • C.

      Get blood to and from the cells of our body

    Correct Answer
    A. Break down our food so that we can absorb (take in) the nutrients
    Explanation
    The digestive system is responsible for breaking down the food we consume into smaller molecules that can be absorbed by the body. This process allows the nutrients present in the food to be taken in and utilized by the cells for various functions such as energy production, growth, and repair. Without the digestive system, our bodies would not be able to extract the necessary nutrients from food, leading to malnutrition and other health issues.

                                     The function of the CIRCULATORY SYSTEM is to.... [pick the best answer]

    • A.

      Deliver nutrients and oxygen to cells by circulating blood around the lungs

    • B.

      Circulate blood around the entire body; delivering nutrients and oxygen AND carrying away waste products

    • C.

      Circulate blood around our legs

    Correct Answer
    B. Circulate blood around the entire body; delivering nutrients and oxygen AND carrying away waste products
    Explanation
    The circulatory system functions by circulating blood around the entire body, delivering nutrients and oxygen to cells, and carrying away waste products. This process ensures that all cells receive the necessary substances for their proper functioning and removes waste materials to maintain homeostasis.

    The function of the GAS EXCHANGE SYSTEM is to ...

    • A.

      Ensure excess gas leaves the intestine

    • B.

      Remove waste products from everywhere in your body

    • C.

      Maintain the sugar level in your blood

    • D.

      Get oxygen into the blood for our cells, and carbon dioxide out of the blood

    Correct Answer
    D. Get oxygen into the blood for our cells, and carbon dioxide out of the blood
    Explanation
    The function of the GAS EXCHANGE SYSTEM is to get oxygen into the blood for our cells, and carbon dioxide out of the blood. This is accomplished through the process of respiration, where oxygen is taken in by the lungs and transported to the bloodstream, while carbon dioxide, a waste product, is removed from the bloodstream and exhaled. This system ensures that our cells receive the oxygen they need for energy production, while also getting rid of the waste product carbon dioxide.

    The function of something is its....

    • A.

      Location (place)

    • B.

      Gas exchange

    • C.

      Job or purpose; what it is for

    • D.

      Top

    Correct Answer
    C. Job or purpose; what it is for
    Explanation
    The function of something refers to its job or purpose, which is what it is meant to do or the role it serves. This answer correctly identifies that the function of something is related to its job or purpose, indicating what it is for. It accurately captures the meaning of the term "function" in this context.

  • 5. 

    Some organs or body parts are involved in more than one  ORGAN SYSTEM. Which of the following are involved in BOTH the DIGESTIVE SYSTEM and the GAS EXCHANGE SYSTEM?

    • A.

      The mouth and the trachea

    • B.

      Just the mouth

    • C.

      The mouth and the oesophagus

    • D.

      Just the trachea

    Correct Answer
    B. Just the mouth
    Explanation
    The mouth is involved in both the digestive system and the gas exchange system. In the digestive system, the mouth is responsible for the initial mechanical and chemical breakdown of food through chewing and saliva production. In the gas exchange system, the mouth serves as an entry point for air during inhalation and exhalation, allowing for the exchange of oxygen and carbon dioxide. The trachea, on the other hand, is only involved in the gas exchange system as it carries air to and from the lungs. The oesophagus is solely part of the digestive system, not the gas exchange system.

    I am an organ system.Food enters me at the mouth and is chewed by the teeth; in the stomach acid breaks down the food further; many more organs process the food ensuring that nutrients from it are passed into the blood. I am the ___________ ____________

    Correct Answer
    digestive system, Digestive System, DIGESTIVE SYSTEM
    Explanation
    The correct answer is "digestive system" or "Digestive System" or "DIGESTIVE SYSTEM". The given description clearly explains the process of food digestion, starting from the mouth where it enters and is chewed by the teeth, then further broken down by stomach acid, and finally processed by many more organs to extract nutrients and pass them into the blood. This entire process is carried out by the digestive system.

    I am an organ system.Smoking can damage my delicate balloon-like alveoli (air sacs),filling them with tar.The less alveoli are working, the less air I can take in. The less air I can take in, the less oxygen gets to the blood for use by the cells of the body.I am the ____________ _____________ _____________

    Correct Answer
    gas exchange system, GAS EXCHANGE SYSTEM, Gas Exchange System
    Explanation
    The correct answer is "gas exchange system". This organ system is responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream. Smoking can damage the alveoli, which are essential for this gas exchange process. When the alveoli are filled with tar, they become less efficient in taking in air and delivering oxygen to the blood. As a result, less oxygen is available for use by the cells of the body.

    The ORGAN that pumps the blood around the body in the circulatory system is the ____________

    Correct Answer
    heart, HEART
    Explanation
    The heart is the organ responsible for pumping the blood around the body in the circulatory system. It acts as a muscular pump, contracting and relaxing to push the blood through the blood vessels, delivering oxygen and nutrients to the body's tissues and organs. The heart plays a vital role in maintaining the circulation of blood, ensuring that all parts of the body receive the necessary oxygen and nutrients for proper functioning.

    In the GAS EXCHANGE SYSTEM:The large tubes that go from the trachea to the lungs are called the ...

    • A.

      Bronchos

    • B.

      Bronchoes

    • C.

      Bronchimoles

    • D.

      Bronchioles

    • E.

      Branches

    Correct Answer
    D. Bronchioles
    Explanation
    Bronchioles are the correct answer in the given question. In the gas exchange system, the bronchioles are the small tubes that branch out from the trachea and lead to the lungs. They are responsible for carrying air to the alveoli, where the exchange of oxygen and carbon dioxide takes place. The bronchioles are smaller in diameter compared to the bronchi, and their narrowing and widening help regulate airflow to different parts of the lungs.

    In the CIRCULATORY SYSTEM:The blood goes from the heart ....

    • A.

      Into the body

    • B.

      Into the body and back to the heart

    • C.

      Just into the lungs

    Correct Answer
    B. Into the body and back to the heart
    Explanation
    The correct answer is "into the body and back to the heart". In the circulatory system, blood is pumped from the heart into the body through arteries, delivering oxygen and nutrients to the cells. After circulating through the body, the blood returns to the heart through veins to be pumped again. This continuous cycle ensures that oxygenated blood reaches all parts of the body and deoxygenated blood is returned to the heart for reoxygenation.
