Which of the following statements about the digestive system is false?
a. the stomach is separated from the small intestine by the pyloric sphincter.
b. chyme is a mixture of food and digestive juices that is produced in the stomach.
c. food enters the large intestine before the small intestine.
d.in the small intestine, chyme mixes with bile, which emulsifies fats.

The false statement about the digestive system is C. Food enters the large intestine before the small intestine.

In the digestive system, there's a ring consisting of smooth muscle called the pyloric sphincter. This separates the stomach from the small intestine. It functions in controlling movement of chyme.

Chyme, on the other hand, are partially digested food that is mixed with digestive juices in the stomach.

Therefore, statement A and B are TRUE.

Statement D is also true because the chyme is passed over to the small intestine to mix with bile. However, food passes through the small intestine before coming to the big intestine.

Therefore, the statement "C. Food enters the large intestine before the small intestine" is FALSE.

The false statement is

Food enters tbe large intestine before the small intestine

Explanation:

Food passea throught the SMALL intestine then into the LARGE intestine

A. increase the size of the muscle cells and the amount of blood that is delivered to the muscle

Explanation:

Muscle endurance is basically the ability of the muscles to repeat a movement many times or hold a position for a extended period of time without stopping to rest, to contract the muscles many times without tiring.

Thus if the muscle endurance has to be increased, firstly the size of cells must increase because cellular organelles specifically mitochondria , myoglobin and capillary networks in SO fibres increases during endurance exercises.  Hypertrophy is caused by resistance exercises,thus there is a high number of FG fibres in power producing muscles than in slow fibres. And for this purpose , increased blood supply to the muscle cells is also required.

Hence, If you wanted to increase your muscular endurance, it would be important to participate in activities that increase the size of muscle cells and amount of blood delivered to the muscle.
