Which reflex is triggered by food in the stomach, relaxes the ileocecal valve, and allows residue into the cecum?
kari74 [83]

Gastroileal reflex is triggered by food in the stomach, relaxes the ileocecal valve, and allows residue into the cecum.

The gastroileal reflex is triggered by the presence of food in the stomach as well as gastric peristalsis.

Gastroileal reflex brings about peristalsis in the ileum as well as the opening of the ileocecal valve, which in turn facilitates the emptying of the ileal constituents into the large intestine or colon.

The gastroileal reflex is one among the three extrinsic reflexes of the gastrointestinal tract. The other two include the gastrocolic reflex as well as the enterogastric reflex.

This type of gastrointestinal reflex is moderated by the vagus nerve and gastrin.

What is the purpose of the menisci found in your knee, jaw, shoulders, and wrists? Why might there be a meniscus there but not,
Blababa [14]

Answer: I believe Meniscus tears are not healed on their own.

Explanation:

Because the two most common causes of a meniscus tear are due to traumatic injury (often seen in athletes) and degenerative processes (seen in older patients who have more fragile cartilage). The most common mechanism of a traumatic meniscus tear occurs when the knee joint is flexed and the knee is then twisted.  The meniscus tear can only be surgically removed. However, in some cases people can live with the meniscus tear without any problem. Also, there are exercises that lessen the symptoms of this problem. The most common symptoms of a meniscus tear are: Knee pain, Knee swelling, Tenderness when pressing the meniscus, Popping or clicking inside the knee, Limited knee joint movement.

20%

Explanation:

The four different bases pair together in a way known as complementary pairing. Adenine always pairs with thymine, and cytosine always pairs with guanine.

if adenine makes

The guanine percent is 30. This is because the other 30% of the 60% is cytosine. Getting back to adenine, it always partners up with thymine as i mentioned before, So it would be 20% thymine and 20% adenine, add those portions to the 60% of the other two, mentioned above and you have 100%.
