Resumo

TLDRThe video elaborates on sexual reproduction and the male reproductive system. It explains that sexual reproduction leads to genetic variation due to the fusion of sperm and ovum. The video provides an overview of the male reproductive anatomy, including the production of sperm in the testes, transport through the epididymis and vas deferens, and the formation of semen through the mixing of sperm with fluids from glands such as the seminal vesicles and prostate gland. The structure and function of sperm are also discussed, highlighting that each sperm is unicellular and designed for mobility and energy.

    The video introduces the concept of sexual reproduction, explaining that variations in children arise from the genetic contribution of both parents through the fusion of gametes. It elaborates on how sexual reproduction leads to genetic diversity. The male reproductive system is highlighted, describing the production and transportation of sperm. Key components include the testes (where sperm is produced), the scrotum (which protects the testes), the epididymis (which carries sperm), and the vas deferens. The journey of sperm continues through the ejaculatory ducts, mixing with nourishing fluids from the seminal vesicle and prostate, culminating in the formation of semen, which is released through the urethra. The structure of sperm is briefly discussed, emphasizing its unicellular nature and the roles of different parts, including the tail for swimming. The segment concludes by indicating that the next video will cover the female reproductive system.

  • 00:00:03
    if you keenly observe every kid has
  • 00:00:07
    characters taking from the parents yes
  • 00:00:10
    characters from both mom and dad have
  • 00:00:14
    you ever wondered why this happens why
  • 00:00:17
    do we find random characters in the kids
  • 00:00:19
    which belong to the same parents in
  • 00:00:22
    simple language we can say that it is
  • 00:00:25
    because of the sexual reproduction in
  • 00:00:27
    organisms yes
  • 00:00:29
    although the logical reasoning can be
  • 00:00:32
    provided by genetics we will not really
  • 00:00:34
    get into the details of it we will
  • 00:00:37
    restrict ourselves to the major process
  • 00:00:39
    responsible for this now you may wonder
  • 00:00:42
    as to how sexual reproduction can be
  • 00:00:45
    responsible for the variations in
  • 00:00:47
    organisms for this we need to stop by
  • 00:00:50
    the definition of sexual reproduction
  • 00:00:52
    once again do you remember what it was
  • 00:00:56
    let me help you sexual reproduction is
  • 00:01:00
    the type of reproduction which involves
  • 00:01:02
    fusion of gametes to give rise to new
  • 00:01:05
    individual now here the term fusion of
  • 00:01:08
    gametes is the answer to a question why
  • 00:01:11
    is that so this is because if we say
  • 00:01:14
    that the zygote is formed with the
  • 00:01:16
    fusion of gametes then it means the
  • 00:01:18
    newly formed individual will have a
  • 00:01:20
    blend of characters does an order to
  • 00:01:23
    learn sexual reproduction we need to
  • 00:01:26
    understand that gametes first gametes
  • 00:01:29
    are sex cells and are different in both
  • 00:01:31
    males and females do you know what
  • 00:01:34
    they're called yes we have come across
  • 00:01:37
    these terms the male gamete is called
  • 00:01:40
    sperm while the female gamete is called
  • 00:01:43
    ovum in order to study them we first
  • 00:01:46
    need to take a glance at the
  • 00:01:48
    reproductive systems this will give us
  • 00:01:51
    an idea of how the gametes are produced
  • 00:01:54
    and help us understand the fertilization
  • 00:01:57
    process better so in this video let us
  • 00:02:00
    learn about the male reproductive system
  • 00:02:02
    to begin with we take a look at the
  • 00:02:05
    location where the sperms are exactly
  • 00:02:07
    produced these oval-shaped structures on
  • 00:02:11
    either side are the ones we are
  • 00:02:12
    referring to
  • 00:02:13
    the single structure is called testes
  • 00:02:16
    while the pair is called testes or
  • 00:02:19
    simply a pair of testicles now these are
  • 00:02:23
    an important part of the system and need
  • 00:02:25
    to be protected right so we have a
  • 00:02:28
    covering of skin over it this forms a
  • 00:02:31
    bag like structure and do we have a name
  • 00:02:33
    for it yes the bag like structure is
  • 00:02:36
    called the scrotum so the scrotum is the
  • 00:02:40
    pouch which contains the testes
  • 00:02:42
    now the sports traduced will have to
  • 00:02:45
    travel in order to reach the female body
  • 00:02:47
    so who will make sure that the sperms
  • 00:02:50
    are carried outside the testes this
  • 00:02:53
    responsibility is taken up by the
  • 00:02:55
    massive coils that we can see here this
  • 00:02:58
    is called the epididymis and the pair is
  • 00:03:01
    called the epididymis the mass then
  • 00:03:05
    carries the sperms to this single
  • 00:03:06
    connecting long coil this is called the
  • 00:03:09
    vas deferens
  • 00:03:11
    where will the deferens carried further
  • 00:03:14
    directly outside the body no they will
  • 00:03:17
    carry to do something called as the
  • 00:03:19
    ejaculatory ducts but where does the
  • 00:03:23
    ejaculatory duct head - it heads to a
  • 00:03:26
    destination where the sperms get mixed
  • 00:03:28
    with the nourishing fluid wait a second
  • 00:03:31
    what kind of fluid are we referring to
  • 00:03:33
    and why is it needed here basically the
  • 00:03:37
    spawns need nourishment to survive also
  • 00:03:40
    they need to be protected from acidic
  • 00:03:43
    conditions coming their way
  • 00:03:44
    hence various glands come to the rescue
  • 00:03:48
    by secreting a few important secretions
  • 00:03:51
    the first one is the seminal vesicle it
  • 00:03:55
    secretes a fluid that helps in
  • 00:03:57
    nourishing the sperms can you see this
  • 00:04:00
    bud like structure here it is the
  • 00:04:02
    prostate gland which helps in secreting
  • 00:04:04
    the prostate fluid now the sperms
  • 00:04:07
    floating in the fluids reach the urethra
  • 00:04:10
    from where they can be released outside
  • 00:04:12
    the body but wait all the secretions are
  • 00:04:16
    not yet completed this B shaped gland
  • 00:04:18
    found here gives another important
  • 00:04:21
    secretion it is called the Cooper's
  • 00:04:23
    gland or even the bubble urethral gland
  • 00:04:26
    now with
  • 00:04:28
    secretion the formation of semen is
  • 00:04:30
    complete the semen is simply the fluid
  • 00:04:34
    carrying the sperms it is carried out by
  • 00:04:36
    the urethra which runs through the penis
  • 00:04:39
    now these pumps will reach the female
  • 00:04:42
    reproductive system and only one among
  • 00:04:44
    all will be able to carry out the
  • 00:04:46
    fertilization of the ovum but tell me
  • 00:04:49
    one thing looking at the structure of
  • 00:04:52
    the single sperm can you guess whether
  • 00:04:55
    it is a unicellular or a multicellular
  • 00:04:57
    structure it is a single cell although
  • 00:05:01
    the structure may not seem to be that of
  • 00:05:03
    a single cell the sperm is definitely
  • 00:05:06
    unicellular it bears a head region
  • 00:05:10
    called the nucleus then it has this
  • 00:05:12
    middle part with the mitochondria for
  • 00:05:15
    providing energy to swim across but then
  • 00:05:18
    who will help in the swimming process
  • 00:05:19
    physically that's the business of the
  • 00:05:22
    steel region the tail helps in the
  • 00:05:26
    swimming activity now we are done with
  • 00:05:28
    the basics of the male reproductive
  • 00:05:30
    system
  • 00:05:31
    let me quickly recap the process we saw
  • 00:05:34
    above the sperms are produced by the
  • 00:05:37
    testes the massive coils called the
  • 00:05:40
    epididymis carries the sperms to the vas
  • 00:05:43
    deferens which is a long coil from there
  • 00:05:46
    it goes to the ejaculatory duct where it
  • 00:05:48
    gets mixed with nourishing fluids from
  • 00:05:52
    there it reaches the urethra and after
  • 00:05:55
    the secretion from the Koopas gland the
  • 00:05:57
    formation of semen is complete so what
  • 00:06:01
    will we learn before the fertilization
  • 00:06:03
    process of course the female
  • 00:06:06
    reproductive system do watch our next
  • 00:06:09
    video to learn more about it
