Steering is simply defined as a mechanism in a vehicle or vessel that makes it possible to steer in different directions. The preferred steering method that will help reduce the possibility of losing control is the push pull method. It is also called hand-to-hand. In this method, each hand remains on its respective wheel side. Whenever you are turning left; your left hand begins by pulling in a downward motion from the 10 o'clock position to the 9 o'clock position. <span />
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.
