Introduction to Female Reproduction System Video Lecture - Biology Class 12 - NEET

0:0:0: the female reproductive system is a
0:0:2: fascinating and complex network of
0:0:4: organs and structures that allows women
0:0:7: to Bear children
0:0:8: one of the most incredible aspects of
0:0:11: this system is the ability of the uterus
0:0:13: to expand up to 500 times its normal
0:0:16: size during pregnancy
0:0:18: just think about that for a moment the
0:0:20: uterus which is a muscular organ the
0:0:23: size of a fist can stretch and grow to
0:0:25: hold a developing fetus for nine months
0:0:29: as we explore the female reproductive
0:0:31: system further we will discover even
0:0:34: more amazing facts and functions that
0:0:36: make this system truly remarkable now we
0:0:39: will start the video by discussing two
0:0:41: categories of female reproductive organs
0:0:44: primary sex organs and accessory sex
0:0:47: organs you have seen this division
0:0:49: earlier in male reproductive system also
0:0:52: where the primary sex organ was a testes
0:0:55: and here in the female reproductive
0:0:57: system the primary sex organs are the
0:1:0: ovaries
0:1:1: and to be more precise primary sex
0:1:4: organs are those organs that are
0:1:6: directly involved in the production of
0:1:8: gametes eggs or sperm and the secretion
0:1:11: of sex hormones and hence ovaries and
0:1:13: testes are primary sex organs
0:1:16: accessory sex organs are those organs
0:1:19: that support the primary sex organs in
0:1:21: the process of reproduction
0:1:24: these include the uterus Fallopian tubes
0:1:27: cervix and vagina
0:1:29: in contrast accessory sex organs in
0:1:32: males include the epididymis vast
0:1:35: difference seminal vesicles prostate
0:1:37: gland and urethra
0:1:40: now there are some more parts in female
0:1:42: reproductive system other than primary
0:1:44: and accessory organs and those are
0:1:46: called as external genitalia
0:1:49: it refers to the visible parts of the
0:1:51: female reproductive system located
0:1:53: outside the body
0:1:55: these parts are also known as the vulva
0:1:58: the external genitalia in females
0:2:1: include the most pubis labia majora
0:2:3: labia minora clitoris hymen membrane
0:2:7: vaginal opening and ureteral opening
0:2:10: now let's understand all the organs and
0:2:13: parts in female reproductive system one
0:2:15: by one and what are their major
0:2:17: functions let's start with ovaries it's
0:2:19: a very important organ in the female
0:2:21: reproductive system and it plays a vital
0:2:24: role in the process of reproduction
0:2:27: think of the ovary as a small oval
0:2:30: shaped organ located on both sides of
0:2:32: the uterus kind of like to tiny little
0:2:34: almonds
0:2:36: each ovary is about the size of a walnut
0:2:39: just like the male reproductive system
0:2:41: is responsible for producing sperm the
0:2:44: female reproductive system is
0:2:46: responsible for producing eggs also
0:2:49: known as over
0:2:50: these eggs are produced in the ovaries
0:2:53: which are oval shaped structures located
0:2:55: on either side of the lower abdomen
0:2:58: so when a girl reaches puberty her
0:3:1: ovaries start to mature and release an
0:3:3: egg approximately once a month in a
0:3:6: process called ovulation
0:3:8: this egg travels down the fallopian tube
0:3:10: and towards the uterus
0:3:12: if the egg is fertilized by a sperm it
0:3:15: will implant itself in the lining of the
0:3:17: uterus and start to grow into a baby
0:3:20: but if the egg is not fertilized it will
0:3:23: disintegrate and the lining of the
0:3:25: uterus will shed causing a menstrual
0:3:27: period
0:3:28: now students to make your preparation
0:3:31: easy and complete you should definitely
0:3:33: check out the notes on the role of the
0:3:35: ovary in the female reproductive system
0:3:38: and guess what
0:3:40: you can find all of the chapter notes
0:3:43: you need in great detail on edurev the
0:3:45: ovaries also secrete hormones like
0:3:48: estrogen and progesterone which play a
0:3:50: crucial role in regulating the menstrual
0:3:52: cycle and contribute to the development
0:3:55: of secondary sexual characteristics in
0:3:57: females such as breast growth and the
0:4:0: widening of the hips but wait how do the
0:4:3: eggs get from the ovaries to where they
0:4:5: need to go
0:4:6: that's where the Fallopian tubes come in
0:4:9: these are to narrow structures that are
0:4:12: connected to the ovaries but they are
0:4:13: not connected directly to it
0:4:16: if we look at it carefully we find that
0:4:18: there are finger-like projections which
0:4:20: connect the two that is ovaries and
0:4:21: fallopian tubes
0:4:23: fimbri are finger-like projections that
0:4:26: extend from the end of the Fallopian
0:4:28: tubes in the female reproductive system
0:4:31: they are responsible for sweeping the
0:4:33: released egg from the ovary into the
0:4:35: fallopian tube
0:4:37: during ovulation an egg is released from
0:4:39: the ovary and travels into the fallopian
0:4:42: tube
0:4:43: the fimbri Creator wave-like motion to
0:4:45: help sweep the egg into the tube where
0:4:47: it can be fertilized by sperm if present
0:4:50: think of the fimbri as tiny fingers that
0:4:53: gently guide the egg into the right
0:4:55: place
0:4:56: without them the egg might not be able
0:4:59: to make it into the fallopian tube and
0:5:1: could be lost
0:5:3: and over also known as an egg cell is a
0:5:6: female reproductive cell in the human
0:5:8: body
0:5:9: it is produced in the ovaries which are
0:5:12: located on either side of the uterus in
0:5:14: the female reproductive system
0:5:16: during ovulation which occurs once per
0:5:19: menstrual cycle an ovum is released from
0:5:22: one of the ovaries and travels through
0:5:24: the fallopian tube towards the uterus
0:5:27: did you know that unlike sperms eggs are
0:5:29: non-metal and can't move on their own
0:5:32: that's why they need the help of the
0:5:34: Fallopian tubes to get to the sperm
0:5:37: and if it encounters sperm along the way
0:5:39: fertilization can occur resulting in the
0:5:42: formation of a zygote which eventually
0:5:44: becomes an embryo
0:5:47: so what happens next
0:5:49: the embryo travels from the Fallopian
0:5:52: tubes to the uterus which is also known
0:5:54: as the womb
0:5:55: uterus is an important part of the
0:5:58: female reproductive system
0:6:0: it is a muscular organ located in the
0:6:2: lower abdomen between the bladder and
0:6:5: rectum
0:6:6: the uterus plays a critical role in
0:6:8: pregnancy as it is a place where a
0:6:11: fertilized egg implants and grows into a
0:6:13: fetus
0:6:14: it is lined with a thick blood-rich
0:6:17: layer called the endometrium which helps
0:6:19: nourish and support the developing fetus
0:6:22: if fertilization does not occur the
0:6:25: uterus sheds its lining during
0:6:27: menstruation which is a normal part of
0:6:29: the menstrual cycle
0:6:31: during childbirth the uterus contracts
0:6:34: to push the baby out through the cervix
0:6:36: and into the vagina
0:6:38: overall the uterus is a vital organ in
0:6:41: the female reproductive system playing
0:6:43: an important role in both pregnancy and
0:6:46: menstruation the vagina is an elastic
0:6:48: muscular Canal that connects the uterus
0:6:51: to the outside of the body
0:6:53: it is an important part of the female
0:6:55: reproductive system
0:6:57: during sexual intercourse the penis
0:7:0: enters the vagina allowing for sperm to
0:7:2: be deposited near the cervix after which
0:7:5: it can potentially fertilize in it
0:7:8: the vagina is also a passageway for
0:7:10: menstrual blood to leave the body during
0:7:12: menstruation
0:7:14: and when it's time for the baby to come
0:7:16: out it will pass through the vagina
0:7:18: which is a small passage that opens to
0:7:20: the exterior
0:7:22: overall the vagina plays an important
0:7:25: role in sexual reproduction and
0:7:27: menstruation and its elasticity and
0:7:29: natural lubrication make it a versatile
0:7:32: and adaptable part of the female body
0:7:34: the cervix is a narrow passage that
0:7:36: connects the vagina to the uterus in the
0:7:39: female reproductive system
0:7:41: it is located at the bottom of the
0:7:43: uterus and acts as a Gateway between the
0:7:45: two organs
0:7:47: during pregnancy the cervix is sealed by
0:7:50: a plug of mucus to protect the
0:7:52: developing fetus from infection
0:7:54: as the baby grows the cervix begins to
0:7:57: soften thin out and open allowing the
0:8:0: baby to pass through the birth canal
0:8:2: during delivery
0:8:4: overall the cervix plays an important
0:8:6: role in both pregnancy and cervical
0:8:9: health and is an important part of the
0:8:11: female reproductive system
0:8:13: now that you know both the reproductive
0:8:16: systems can you tell me which one is
0:8:18: more complex than the other one
0:8:20: just think for a moment if you think it
0:8:23: is the male reproductive system then you
0:8:25: may be wrong
0:8:26: because it is the female reproductive
0:8:28: system which is more complex than the
0:8:31: male reproductive system because it not
0:8:33: only produces eggs but also supports the
0:8:35: growth and development of a baby
0:8:38: but don't worry we will learn more about
0:8:41: how every organ in the system works
0:8:43: together to create new life in the next
0:8:46: parts of the video
0:8:47: which include ovary fallopian tube finry
0:8:51: ovum uterus cervix and vagina in detail
0:8:54: and easy way
0:8:56: we hope that you have understood the
0:8:58: topic
0:8:59: now here is a secret on how you can
0:9:2: study effectively with the edge of app
0:9:5: you can learn with chapter notes watch
0:9:7: video lectures and solve ncrt based McQ
0:9:11: tests of this chapter on eduriff
