Question

Stretching of uterine walls, cause contractions that further stretch the walls. This is an example of which type of feedback mechanism? Explain your answer with proper justification?​

Answer 1

Answer:

Examples of processes that utilise positive feedback loops include:

Childbirth – stretching of uterine walls cause contractions that further stretch the walls (this continues until birthing occurs)

Lactation – the child feeding stimulates milk production which causes further feeding (continues until baby stops feeding)

Ovulation – the dominant follicle releases oestrogen which stimulates LH and FSH release to promote further follicular growth

Blood clotting – platelets release clotting factors which cause more platelets to aggregate at the site of injury
