  • Q #2: Which of the heart chambers is the largest?

    A. Left atrium

    B. Right atrium

    C. Left ventricle

    D. Right ventricle

    Answer Explanation

    Of the four heart chambers, the left ventricle is the largest. When it contracts, it pushes blood out to the organs and extremities of the body. The right ventricle pushes blood into the lungs. The atria, on the other hand, receive blood from the outlying parts of the body and transport it into the ventricles.

    The basic process works as follows: Oxygen-poor blood fills the right atrium and is pumped into the right ventricle. from which it is pumped into the pulmonary artery and on to the lungs. In the lungs, this blood is oxygenated. The blood then reenters the heart at the left atrium, which, when full, pumps into the left ventricle. When the left ventricle is full, blood is pushed into the aorta and on to the organs and extremities of the body.

  • Q #3: Which section of the digestive system is responsible for receiving chyme and further digesting it?

    A. The large intestine

    B. The duodenum

    C. The jejunum

    D. The gallbladder

    Answer Explanation

    The duodenum is the first section of the small intestine. It receives partially digested food (also called chyme) from the stomach, further digesting it with the help of enzymes released by the gall bladder. Then, the food enters into the jejunum, then the ileum. The large Intestine's main function is the reabsorption of water into the body to form solid waste. It also allows for the absorption of vitamin K produced by microbes living inside the large intestine.
