Question

Valves of Kerckring occur in
a) Between right auricle right ventricle
b) Left auricle and left ventricle
c) Stomach and duodenum
d) Intestine

Answer 1

Hint: As various pathways in the body are opened, closed, or partially obstructed, a valve is a mechanism or natural entity that monitors, controls, or controls fluid flows. In anatomy of any of the various membrane structures, especially in the heart, veins, and lymph canals, valves that act temporarily close a passage and a void, allowing fluid to flow only in one direction.

Complete answer:
The round folds (also known as Kerckring's valves, Kerchkring's valves, plicae circulares, plicae circulares, and valvulae conniventes) are massive valvular folds that project into the lumen of the small intestine. The conniventes are the mucous folds of the small digestive system, which start from the second piece of duodenum; they are large and thick on the jejunum and decline widely, in the distal size, in the ileum to completely disappear into the distal Ileum's interior circles.

Hence, option D- Intestine is the correct option.

Additional Information:
Theodorus Kerckring (1640-1693) was a German-conceived anatomist who lived in Amsterdam. He likewise depicted the Kerckring ossicle 3.
Valvulae conniventes, signifies 'joining little valves'. The term is gotten from the Latin valvula, the minor of valve meaning little valve, and conniventes, is the plural type of the current participle of the action word 'conniveo' which means to unite. Plicae circulares, which means "circular creases," is derived from the Latin word’s plica, which means "overlay" (it is the Terminologia Anatomica expression for an overlap) and circulares, which means "circular."

Note:
A muscle sphincter, two or three membranous flaps or folds, and a muscle sphincter can all be found in a valve. A set of constant spiral or circular folds, known as the circular plicae, are used to enhance the area surface of the organ to encourage efficient absorption of nutrients.
