It’s about chapter 4, one + one =three. It’s a summary of the whole chapter, however it is in english because my education is in english (tweetalig vwo).
Content:
- anatomy of the male and female reproductive organs.
- the formation of male and female sex cells.
- how hormones affect sex ...
Asexual reproduction = the type of reproduction that does not involve the fusion of egg and sperm
cell, and thus requires only one parent (reproduction without having sex)
Sexual reproduction = type of reproduction that involves two parents that reproduce unique
offspring.
Fission = a method when the body of an organism splits into two separate individuals, it can
reproduce sexual and asexual in this way.
Hermaphrodite = when one organism is considered both male and female, these animals can make
sperm and egg cells.
The egg and sperm cells are released in the water and once they meet, a larvae will grow, eventually
a new sea anemone can develop.
Summary biology:
Section 2,
Testes: male organs that
produce sperm cells.
Seminiferous tubules: tubes
within the testes in which
sperm cells develop.
Epididymis: cap-like
structure on top of each
testis in which sperm is
stored temporarily.
Sperm ducts:
Tubes that lead sperm from
the testes towards the
urethra.
Seminal vesicles: glands that
reproduce fluid which
nourishes sperm and enables
them to swim.
Prostate gland: gland that
produces. additional fluid
nourishes sperm and enables them to swim.
Semen: sperm cells and fluid together.
Urethra: tube inside the penis that transports noth semen and urine out of the body.
Ejaculation: the process of semen passing out of the body.
Erectile tissue: spongy tissue that makes the penis erect when blood is pumped into it.
, Ovary: paired almond
sized organ in which
egg cells develop.
Oviduct: tube like
structure that
transports the egg cell
towards the uterus.
Uterus: hollow pear
shaped organ with a
muscular wall
Cervix: narrow opening
at the bottom of the
uterus
Birth canal: tube like
structure through
which a baby travels through during childbirth, also called a vagina.
Vulva: the area where the vagina is open to the outside.
Clitoris: sensitive organ above the urethral opening.
Inner labia: two inner folds of skin that surround and protect the vulva.
Outer labia: two outer folds of skin that surround the inner labia and protect the vulva.
Summary biology:
Section 3,
Hormones are chemicals secreted by glands in
your body.
Gland: organ that makes a substance to release
into the body.
Target organ: a tissue or organ in which a
hormone causes a reaction.
Around the age 8-13 the body starts to change in
an adult called puberty.
The ovaries in girls and the testes in boys will
respond to the hormones travelling in your blood
to the seks organs by making so called sex
hormones.
Seks hormones: hormones that control the
reproductive system.
Hormones changes things a lot, for females the body shape changes, menstruation, pregnancy and
for the information of organs such as breasts. In males, sex hormones are responsible for a male
body shape and for the information of facial hair, chest hair, a deeper voice and growth of the male
organs such as testes and penis. The hormones also trigger the cells: egg cells and sperm cells. They
transfer hereditary information to the next generation.
The hormones also effect the brain, the brain is reinventing itself as it prepares you for adulthood.
Teenagers suffer from mood swings, puberty is sometimes described as an emotional rollercoaster.
