This Class 12 Biology flow chart for Chapter 3 Human Reproduction summarises the male reproductive system, the female reproductive system, gametogenesis (spermatogenesis and oogenesis), the menstrual cycle, and fertilisation, implantation, parturition and lactation, in the order given in the chart.
CHAPTER 3: HUMAN REPRODUCTION (FLOW CHART)
(1) Male reproductive system
Male accessory ducts - rete testis, vasa
Testes - primary organ in scrotum
Male accessory gland - seminal vesicle, prostate gland, bulbourethral
Testes → Testicular lobule - 250 compartments → Seminiferous tubule - highly coiled tubule - 3
Leydig cells - secrete androgen
Seminiferous tubule → Spermatogonia - form sperms by meiosis
Seminiferous tubule → Sertoli cells - provide nutrition to germ cells
(2) Female reproductive system
Accessory ducts - oviduct - (infundibulum, ampulla, isthmus), uterus - (perimetrium,
Ovary - primary organ
Mammary gland - alveoli, mammary tubule, mammary
(3) Gametogenesis - formation of gametes
Spermatogenesis - formation of sperms:
Spermatogonia - at puberty →
Primary spermatocyte - diploid undergo meiosis I →
Secondary spermatocyte - →
Spermatids - undergo spermiogenesis →
Spermatozoa/sperm
Oogenesis - formation of ovum:
Oogonia - During embryonic development →
Primary oocyte - upto Prophase I - primary follicle, secondary follicle, →
Secondary oocyte - ovulation occur →
After the entry of sperm - completes Meiosis II →
Ovum
(4) Menstrual Cycle
Menstrual phase - break down of
Follicular phase - Ovary - Primary Follicle to Graafian follicle, Uterus -
Ovulatory phase - release of ovum
Luteal phase - Corpus luteum - progesterone -
(5) Fertilisation and implantation
Sperm + Ovum → Fertilisation → Zygote → Cleavage - blastomeres → Morula → Blastocyst
Blastocyst → Trophoblast - gets → Placenta - supply O2, nutrients, remove CO2 and wastes secrete
Blastocyst → Inner cell mass - embryo - ectoderm, → Foetal ejection reflex - signal from fully → Parturition - → Lactation - colostrum - milk produced during
