Answer:
b. The ampulla region with highly folded mucosa.
Explanation:
The uterine tubes are two structures that transport the oocyte from the ovary to the uterus. It has four regions, starting with the one closer to the ovaries they are:
Fimbriae: they are ciliated projections that once the ovary releases the oocyte, they capture it and guide it to the interior of the uterine tube.
Infundibulum: this is the portion of the uterine tube that takes the oocyte. It has a conic shape.
Ampulla: It is the region that follows after the infundibulum. It is the longest segment of the ovary ducts, and it is where the sperm meets the oocyte, in other words, where fertilization occurs. The mucosa lining in this area has primary, secondary, and tertiary mucosa folds. They have cells that provide nutrients to the egg and move it towards the uterus.
Isthmus: It is the last part of the uterine tubes. It connects the ampulla to the uterus, and its function is to deliver the eggs to the uterus. The mucosa has fewer folds.
The doctor removed the uterine tube because, even though the fertilization happens in the ampulla of this organ, the fertilized egg then has to move to the uterus to keep its development.
Answer:
The false statement is-Our body has no mechanism to stabilize free radicals.
Explanation:
Free radicals are the atoms produced in the cell mainly due to oxidative stress. For example, oxygen splits into an atom having an unpaired electron. So these atoms having unpaired electrons are called free radicals.
Free radicals are responsible for damaging DNA and causing cancers in the body. In our cells antioxidants are present which checks the presence of free radicals in the cell.
They stop the free radicals chain reaction and eliminate the free radicals in the cell by giving an electron to free radicals without getting destabilized. Therefore our bodies have a mechanism to fight with free radicals.
