2.1 The diagram below represents the female reproductive system.

2.1.1 Identify part B

2.1 The diagram below represents the female reproductive system.

2.1.2 Name the process that takes place in part A that leads to zygote
formation.

2.1 The diagram below represents the female reproductive system.

2.1.3    Describe the process named in QUESTION 2.1.2.

2.1.4 Describe the development of the zygote until implantation occurs.

2.1.5     Explain TWO ways in which part D is structurally suited for
gestation.

2.1.6 Describe how the secretion of the prostate gland provides
protection for the sperm from the conditions in part C.

PLASTIC LINKED TO FEMALE INFERTILITY
Several studies indicate that bisphenol A (BPA), a chemical used in the
production of many household plastic products, may be linked to female
infertility (inability to get pregnant naturally and to deliver a healthy baby).
BPA can be ingested or absorbed through the skin when using plastic
products.
BPA seems to interfere with the normal secretion of FSH by the pituitary
gland and is linked to abnormal menstrual cycles and reduced implantation
rates. These studies also show a link between high BPA levels and a
decrease in the development and maturation of ovarian follicles.

2.2.1 State ONE function of FSH.

2.2.2 Name ONE other hormone in females that is secreted by the
pituitary gland during the menstrual cycle.

2.2.3 Explain how an under-secretion of the hormone in QUESTION 2.2.2
may lead to infertility.

2.2.4 Explain why a decrease in the maturation of ovarian follicles may
lead to reduced implantation rates.
