    • D.

      Cerebrum and cerebellum

    Correct Answer
    B. Medulla Oblangata and pons of the mid brain
    Explanation
    The correct answer is Medulla Oblangata and pons of the mid brain. The medulla oblongata and pons are responsible for controlling the basic functions of respiration. The medulla oblongata contains the respiratory centers that regulate the rate and depth of breathing. It receives information from chemoreceptors that detect changes in oxygen and carbon dioxide levels in the blood, and adjusts breathing accordingly. The pons acts as a bridge between the medulla oblongata and the higher brain centers, helping to coordinate the rhythm and pattern of breathing. Together, the medulla oblongata and pons play a crucial role in maintaining the body's respiratory function.

      Veins

    • C.

      Capillaries

    • D.

      Nerves

    Correct Answer
    A. Arteries
    Explanation
    Arteries are the blood vessels that carry oxygenated blood away from the heart to the rest of the body. They have thick, elastic walls that help them withstand the high pressure of the blood pumped by the heart. Arteries branch out into smaller vessels called arterioles, which further divide into capillaries. Capillaries are responsible for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. After this exchange, the deoxygenated blood is then carried back to the heart through veins. Nerves, on the other hand, are not blood vessels and do not transport blood.

    Rate this question:

  • 15. 

    Pulmonary vein carries _____________ blood.

    • A.

      Oxygenated

    • B.

      De-oxygenated

    • C.

      Both

    • D.

      None of the above

    Correct Answer
    A. Oxygenated
    Explanation
    The pulmonary vein carries oxygenated blood. This is because the pulmonary veins transport blood from the lungs back to the heart, and in the lungs, oxygen is added to the blood while carbon dioxide is removed. Therefore, the blood in the pulmonary vein is rich in oxygen and ready to be pumped to the rest of the body.

      Systole

    • C.

      Pulse

    • D.

      Conduction

    Correct Answer
    B. Systole
    Explanation
    During the contraction phase of the heart, known as systole, both ventricles contract simultaneously to pump blood to the lungs and the rest of the body. This is an essential process that ensures proper circulation and delivery of oxygen and nutrients to all the organs and tissues. Diastole, on the other hand, refers to the relaxation phase of the heart when the ventricles fill with blood. Pulse is the rhythmic expansion and contraction of the arteries due to the heart's pumping action. Conduction refers to the electrical signals that coordinate the heart's contractions.

      Blood cells

    • D.

      Capillaries

    Correct Answer
    B. Nephrons
    Explanation
    The correct answer is nephrons. Nephrons are the structural and functional units of the kidney. They are responsible for filtering waste products, excess water, and electrolytes from the blood to produce urine. Each kidney contains millions of nephrons, which consist of a glomerulus, renal tubules, and collecting ducts. The glomerulus filters blood, while the renal tubules reabsorb useful substances and excrete waste products. The collecting ducts collect urine and transport it to the renal pelvis for elimination. Nephrons play a crucial role in maintaining the body's fluid balance, electrolyte levels, and acid-base balance.

    The intestinal lymphatic system helps transport:

    • A.

      Digested fats

    • B.

      Digested minerals

    • C.

      Digested proteins

    • D.

      Digested vitamins

    Correct Answer
    A. Digested fats
    Explanation
    The intestinal lymphatic system helps transport digested fats. This system plays a crucial role in absorbing dietary fats and fat-soluble vitamins from the small intestine. After digestion, the fats are converted into small droplets called chylomicrons, which are then transported into the lymphatic vessels called lacteals. These lacteals eventually merge with the bloodstream, allowing the fats to be delivered to various tissues and organs throughout the body. This process is essential for the absorption and utilization of dietary fats for energy production and other physiological functions.

      Sensory

    • C.

      Efferent

    • D.

      Vagus nerve

    Correct Answer
    B. Sensory
    Explanation
    Sensory neurons are responsible for receiving information from the external environment and transmitting it to the central nervous system. These neurons are specialized to detect various stimuli such as touch, temperature, pain, and sound, and convert them into electrical signals that can be interpreted by the brain. This allows us to perceive and respond to the world around us. Motor neurons, on the other hand, carry signals from the central nervous system to the muscles and glands, enabling movement and bodily functions. Efferent neurons are a type of motor neuron that specifically transmit signals away from the central nervous system. The vagus nerve is a cranial nerve that contains both sensory and motor fibers, but its main function is to regulate the parasympathetic nervous system.

    • C.

      Somatic

    • D.

      None of the above

    Correct Answer
    A. Sympathetic
    Explanation
    The sympathetic nervous system is responsible for the flight or fight response of the body. When faced with a perceived threat or danger, the sympathetic nervous system activates to prepare the body for action. It increases heart rate, dilates blood vessels, and releases stress hormones like adrenaline, all of which help to mobilize the body's resources and prepare it to either confront the threat or escape from it. The sympathetic nervous system is part of the autonomic nervous system, which controls involuntary bodily functions.

    _____________ controls the movement of partially digested food from stomach to duodenum.

    • A.

      Sphincter of oddi

    • B.

      Pyrolic sphincter

    • C.

      Lleocecal sphincter

    • D.

      None of the above

    Correct Answer
    B. Pyrolic sphincter
    Explanation
    The correct answer is the Pyrolic sphincter. The Pyrolic sphincter is a circular muscle located between the stomach and the duodenum. Its main function is to control the movement of partially digested food from the stomach into the small intestine. When the food is ready to be passed into the duodenum for further digestion and absorption, the Pyrolic sphincter relaxes, allowing the food to pass through. Once the food has passed through, the sphincter contracts again to prevent the backflow of stomach acid into the stomach.

    • A.

      Anti-peristaltic movement

    • B.

      Peristaltic movement

    • C.

      Sliding movement

    • D.

      None of the above

    Correct Answer
    B. Peristaltic movement
    Explanation
    Peristaltic movement refers to the coordinated contraction and relaxation of muscles in the gastrointestinal (GI) tract, which helps to propel food through the digestive system. This movement involves a wave-like motion that pushes the food forward, allowing for efficient digestion and absorption of nutrients. Anti-peristaltic movement, on the other hand, would be the reverse motion, pushing food in the opposite direction, which is not a normal physiological process in the GI tract. Sliding movement is not a recognized term in the context of GI motility. Therefore, the correct answer is peristaltic movement.

    Oestrogen and Progesterone are hormones that play a crucial role in the female reproductive system. They are primarily secreted by the ovaries, which are the female reproductive organs responsible for producing eggs and releasing them during ovulation. The ovaries also produce these hormones to regulate the menstrual cycle, promote the development of secondary sexual characteristics, and support pregnancy. The pituitary gland and hypothalamus are involved in regulating the production and release of these hormones, but they do not directly secrete oestrogen and progesterone. The testis, on the other hand, secretes testosterone, which is the primary male sex hormone.
