    What is the main organ of the Circulatory system?

    • Heart

    • Spleen

    • Adrenal

    • Liver

    • Vessels

    Correct Answer
    A. Heart
    Explanation
    The main organ of the circulatory system is the heart. It is responsible for pumping blood throughout the body, supplying oxygen and nutrients to the organs and tissues. The heart consists of four chambers that work together to ensure proper circulation. It receives deoxygenated blood from the body and sends it to the lungs to be oxygenated, then pumps the oxygenated blood back to the body. Without the heart, the circulatory system would not be able to function properly, and the body would not receive the necessary oxygen and nutrients.

    Correct Answer
    A. Brain
    Explanation
    The brain controls breathing. It sends signals to the muscles responsible for breathing, such as the diaphragm and intercostal muscles, to contract and relax, allowing air to enter and leave the lungs. The brain constantly monitors the levels of oxygen and carbon dioxide in the blood and adjusts the breathing rate and depth accordingly to maintain a balance. Without the brain's control, the body would not be able to regulate breathing properly.

    Which system is included in Control systems except for the Nervous system?

    • The lymphatic system

    • The Respiratory system

    • The Endocrine system

    • The Digestive system

    • The Urinary system

    Correct Answer
    A. The Endocrine system
    Explanation
    The endocrine system is the correct answer because it is a system that regulates and controls various bodily functions through the release of hormones. It works in conjunction with the nervous system to maintain homeostasis in the body. The other options listed (lymphatic system, respiratory system, digestive system, and urinary system) are not control systems but rather systems that have different functions such as immune response, gas exchange, nutrient absorption, and waste elimination, respectively.

    Which endocrine organ releases the hormone which increases the heartbeats and blood glucose level?

    • Adrenal

    • Pituitary glands

    • Thyroid glands

    • Mammary gland

    • Pancreas

    Correct Answer
    A. Adrenal
    Explanation
    The adrenal gland releases the hormone called adrenaline, which increases heart rate and blood glucose levels. Adrenaline is released in response to stress or danger, preparing the body for a fight or flight response. It increases heart rate to pump more blood to the muscles and raises blood glucose levels to provide energy for the body to respond to the stressful situation.

    What does occur when the coronary circulation is blocked?

    • The blood can't move in the vessels

    • White blood cells can't destroy the harmful microorganisms

    • Platelets don't form clots

    • Oxygen and nutrients cannot reach all the cells.

    • All of above

    Correct Answer
    A. Oxygen and nutrients cannot reach all the cells.
    Explanation
    When the coronary circulation is blocked, it means that the blood flow to the heart muscle is restricted. This can occur due to the buildup of plaque in the coronary arteries, leading to a condition called coronary artery disease. When the circulation is blocked, oxygen and nutrients cannot reach all the cells in the heart muscle. This can result in chest pain or angina, and if the blockage is severe, it can cause a heart attack. Therefore, the correct answer is that oxygen and nutrients cannot reach all the cells.
