    Which gas does your body need to stay alive?

    Explanation
    Oxygen is the gas that our body needs to stay alive. It is essential for the process of respiration, where oxygen is taken in by the lungs and transported to the cells through the bloodstream. In the cells, oxygen is used to produce energy through a process called cellular respiration. Without an adequate supply of oxygen, our body's cells would not be able to function properly, leading to organ damage and eventually death.

    What is the definition of "DIAPHRAGM"?

    • The part of your body that takes oxygen from the air

    • The main muscle used in breathing

    • A waste gas made in your body

    • Our eating habitat

    Correct Answer
    A. The main muscle used in breathing
    Explanation
    The correct answer is "the main muscle used in breathing." The diaphragm is a dome-shaped muscle located below the lungs that plays a crucial role in the process of breathing. When we inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity and allowing the lungs to expand and fill with air. When we exhale, the diaphragm relaxes and moves upward, pushing air out of the lungs. Therefore, the diaphragm is the primary muscle responsible for the mechanical aspect of breathing.

    • Heart

    • Lung

    Correct Answer
    A. Heart
    Explanation
    The correct answer is "heart" because the heart is located in the chest, slightly to the left, and can be felt pulsating in the wrist due to the radial artery passing over it. The heart is responsible for pumping blood throughout the body, and its rhythmic contractions can be felt in various parts of the body, including the wrist.

    • Heart

    • Pulse

    Correct Answer
    A. Diaphragm
    Explanation
    The diaphragm is the main breathing muscle because it plays a crucial role in the process of inhalation and exhalation. When we inhale, the diaphragm contracts and moves downward, creating more space in the chest cavity for the lungs to expand and fill with air. This allows us to take in oxygen. On the other hand, when we exhale, the diaphragm relaxes and moves upward, pushing the air out of the lungs. Without the diaphragm's contraction and relaxation, the process of breathing would not be possible.

    What is the definition for "PULSE"??

    • A muscle that is at work all the time

    • Tubes that carry blood

    • The stretching of some blood vessels

    • Carries nutrients,oxygen,and other things in it

    Correct Answer
    A. The stretching of some blood vessels
    Explanation
    The correct answer is "the stretching of some blood vessels." This definition refers to the pulsation or expansion of certain blood vessels, such as arteries, as a result of the heartbeat. When the heart contracts, it pushes blood through the arteries, causing them to stretch and create a pulse. This pulse can be felt in different parts of the body, such as the wrist or neck, and is used to measure heart rate and assess overall cardiovascular health.
