Question

3) What will happen if: i) Peristaltic movements do not occurs all along the esophagus. ii) There are no platelets in blood. iii) Rings of cartilage are not present in trachea

Answer 1

If peristaltic movements do not occur along the oesophagus then the food that we took inside our mouth will not get pushed down through the oesophagus (or foodpipe).

If there are no platelets in blood than if we get even small cut, the blood flowing out of the cut will not stop.

If rings of cartilage are not present in trachea, then in the absence of air, they will collapse.
