    The bladder is a saclike muscular organ of the excretory system which stores urine until it is released from the body?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that the bladder is indeed a saclike muscular organ of the excretory system. Its main function is to store urine that is produced by the kidneys until it is released from the body through the process of urination. The bladder expands as it fills with urine and contracts when it is time to empty. This process is controlled by the nervous system, specifically the reflex that triggers the urge to urinate. Therefore, it is true that the bladder stores urine until it is released from the body.

    What is the main organ of the respiratory system where gases are exchanged?

    • Heart

    • Lungs

    • Breast

    • Stomach

    Correct Answer
    A. Lungs
    Explanation
    The main organ of the respiratory system where gases are exchanged is the lungs. The lungs are responsible for taking in oxygen from the air and releasing carbon dioxide, which is a waste product, out of the body. This exchange of gases occurs in tiny air sacs called alveoli, which are present in the lungs. The oxygen is then transported to the cells of the body through the bloodstream, while carbon dioxide is carried back to the lungs to be exhaled.

    The Circulatory system and the Respiratory system are two systems the excretory system work with to remove wastes from the body and to make sure that oxygen reaches the blood stream and corbon dioxide is removed.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The circulatory system and the respiratory system are both involved in the excretory system's function of removing waste from the body. The circulatory system transports waste products to the excretory organs, such as the kidneys, for elimination. The respiratory system helps in the removal of carbon dioxide, a waste product, by exchanging it with oxygen through the process of breathing. Therefore, it is true that the excretory system works with the circulatory and respiratory systems to remove waste and ensure oxygen reaches the bloodstream.

    What are some disorders of the respiratory system?

    • Coughing, sneezing, watery eyes, hives

    • Emphysema, bronchitis, respiratory infection, asthma, lung cancer

    • Diarrhea, stomach virus, liver disease, skin disease

    Correct Answer
    A. Emphysema, bronchitis, respiratory infection, asthma, lung cancer
    Explanation
    The correct answer is Emphysema, bronchitis, respiratory infection, asthma, lung cancer. These disorders are all related to the respiratory system. Emphysema is a chronic lung condition that causes shortness of breath, bronchitis is inflammation of the bronchial tubes, respiratory infection refers to any infection of the respiratory tract, asthma is a chronic condition that causes airway inflammation and constriction, and lung cancer is a malignant tumor that originates in the lungs. These disorders can all affect the normal functioning of the respiratory system and may require medical intervention.

    Breathing is the movement of the chest that brings air into the lungs and removes wast gases

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Breathing is indeed the movement of the chest that allows air to enter the lungs and expels waste gases. This process is essential for the exchange of oxygen and carbon dioxide in the body. The diaphragm and intercostal muscles contract and relax, causing the chest cavity to expand and contract, creating a pressure gradient that facilitates the movement of air in and out of the lungs. Therefore, the statement "Breathing is the movement of the chest that brings air into the lungs and removes waste gases" is accurate and true.

    What are the organs of the excretory system that giet rid of urea, excess water, and some other waste materials released by the cells?

    • Liver

    • Bile

    • Kidneys

    • Eyes

    Correct Answer
    A. Kidneys
    Explanation
    The kidneys are the organs of the excretory system that help in getting rid of urea, excess water, and other waste materials released by the cells. They filter the blood and remove waste products, which are then excreted as urine. The liver also plays a role in the excretory system by metabolizing and detoxifying substances, but it is not primarily responsible for removing urea and excess water from the body. Bile is produced by the liver and helps in the digestion and absorption of fats, but it is not directly involved in excretion. The eyes are not part of the excretory system and do not eliminate waste materials.

    Which organ is also called the windpipe and moves air from the nose to the lungs?

    • Esophagus

    • Throat

    • Trachea

    Correct Answer
    A. Trachea
    Explanation
    The organ that is also called the windpipe and moves air from the nose to the lungs is the trachea. The trachea is a tube-like structure located in the throat, just below the larynx. It is responsible for carrying air to and from the lungs, allowing for the process of respiration. The trachea is lined with tiny hair-like structures called cilia, which help to filter out dust and other particles from the air before it reaches the lungs.

  • 9. 

    What are the tubes that lead to each lung and move air form the trachea to the lungs?

    Correct Answer
    Bronchi
    Explanation
    The tubes that lead to each lung and move air from the trachea to the lungs are called bronchi. These are the main passageways that branch off from the trachea and enter into the lungs. The bronchi further divide into smaller branches known as bronchioles, which eventually lead to the alveoli, where gas exchange occurs. The bronchi play a crucial role in delivering oxygen to the lungs and removing carbon dioxide from the body.

    What is the tube through which urine passes before it is removed from the body?

    Correct Answer
    urethra
    Explanation
    The urethra is the tube through which urine passes before it is removed from the body. It connects the bladder to the external opening of the body, allowing urine to be expelled during urination. The urethra is responsible for transporting urine from the bladder to the outside of the body, allowing for the elimination of waste products.

  • 11. 

    Besides your urinary system what other organ(s) in your body help in excretion?

    • Skin Lungs heart, skin, lungs, liver

    • Liver, skin, colon, throat

    • Lungs, kidney, skin, pulse

    • Skin, lungs, liver, kidney

    Correct Answer
    A. Skin, lungs, liver, kidney
    Explanation
    The skin is one of the organs in the body that helps in excretion. It eliminates waste products such as sweat and sebum through sweat glands and sebaceous glands. The lungs also play a role in excretion by removing carbon dioxide, a waste product of cellular respiration, through breathing. The liver is responsible for metabolizing and detoxifying various substances, including drugs and toxins, and excreting them in bile. The kidneys are the main organs of excretion, filtering waste products from the blood and producing urine to eliminate them from the body.

    The colon is the name of the muschle that aids in the breathing process.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. The colon is not the muscle that aids in the breathing process. The muscle responsible for breathing is the diaphragm. The colon, on the other hand, is part of the digestive system and is responsible for absorbing water and electrolytes from undigested food, forming feces, and eliminating waste from the body.

    What are the tubes that connect each kedney to the bladder?

    Correct Answer
    ureters
    Explanation
    The tubes that connect each kidney to the bladder are called ureters. These narrow tubes play a crucial role in the urinary system by transporting urine from the kidneys to the bladder. The ureters ensure the continuous flow of urine by using peristalsis, a series of muscular contractions, to push the urine forward. Once the urine reaches the bladder, it is stored until it is expelled from the body during urination.

    Rate this question:

  • 14. 

    How much of your blood passes though your kidneys each day?

    Correct Answer
    All of it
    Explanation
    The kidneys are responsible for filtering waste products and excess fluid from the blood, producing urine. They receive a large amount of blood supply from the renal arteries. Every drop of blood that circulates through the body passes through the kidneys for filtration. Therefore, it can be concluded that all of the blood in the body passes through the kidneys each day.

    The functions of the respiratory system is to provide gasic air to the blood

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The respiratory system is responsible for the exchange of gases between the body and the environment. It ensures that oxygen from the inhaled air enters the bloodstream and carbon dioxide, a waste product, is removed. This process occurs in the lungs, where oxygen is absorbed into the blood vessels and carbon dioxide is released. Therefore, the statement that the functions of the respiratory system are to provide gaseous air to the blood is true.

    Rate this question:

  • 16. 

    Which organ collects air form the environment and moistens and heats the air before it enters the trachea?

    Correct Answer
    nasal cavity
    Explanation
    The nasal cavity is the organ that collects air from the environment and performs important functions before it enters the trachea. It moistens the air by producing mucus, which helps to keep the respiratory system hydrated. The nasal cavity also heats the air as it passes through, bringing it closer to body temperature before it reaches the lungs. These processes are crucial for protecting the delicate tissues of the respiratory system and ensuring optimal functioning of the lungs.

    Rate this question:

  • 17. 

    What are the air sacs in the lungs where gas exchange takes place?

    Correct Answer
    alveoli, Alveoli
    Explanation
    The air sacs in the lungs where gas exchange takes place are called alveoli. These tiny, balloon-like structures are located at the end of the bronchial tubes and are surrounded by a network of capillaries. The alveoli are the primary sites for the exchange of oxygen and carbon dioxide between the lungs and the blood. Oxygen from the air you breathe diffuses through the walls of the alveoli and into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled.
