Question

Name the site of fertilisation in the human female reproductive system and zygote implantation site after fertilisation?

Answer 1

Fertilization is a natural life process that involves the union of male and female gametes, resulting in the development of a zygote. In humans, the fallopian tube is where fertilisation takes place.
Thousands of sperms are inseminated into the female vagina during this process. The sperms go towards the uterus and eventually reach the fallopian tube's opening. Only a small percentage of sperm will make it to the fallopian tube's entrance.

Complete answer:
The female reproductive system serves a variety of purposes. The egg cells, known as ova or oocytes, are produced by the ovaries. The oocytes are subsequently transferred to the fallopian tube, where they may be fertilised by sperm. The fertilised egg is subsequently transferred to the uterus, where the uterine lining has expanded in response to the reproductive cycle's typical hormones.The fertilised egg can implant into the thicker uterine lining and continue to develop once inside the uterus. The uterine lining is lost as menstrual flow if implantation does not occur. The female reproductive system also produces female sex hormones, which help to keep the reproductive cycle going.
Steps of fertilisation in human beings-
Acrosomal reaction
Cortical reaction
Sperm entry
Karyogamy
Activation of eggs
Implantation
Sex determination

Note:
Phases of menstrual cycle-
Menstrual phase: On the first day of menstruation, the uterus lining that has been prepared for implantation begins to shed, lasting $3 - 5$ days.
A developed egg follicle releases an egg from one of the ovaries during the follicular period. In addition, the uterus begins to prepare for another pregnancy.
Ovulatory phase: Also known as the mid-cycle phase, this is when ovulation occurs, which occurs between days $13$ and $17$. The fertilisation period is defined by the end of the follicular phase and the ovulation period.
The fate of the corpus luteum is chosen during the luteal phase, which occurs after ovulation. If fertilisation takes place, the pregnancy process begins. If fertilisation does not take place, another cycle begins.
