Cells and reproduction Flashcards
(23 cards)
cell membrane
controls what goes in and out of the cell
cytoplasm
Where chemical reactions take place
Nucleus
Contains DNA and controls the function of the cell
Chloroplast
Where photosynthesis occurs
Vacuole
storage areas for cells and keeps the cell firm
Cell Wall
supports and protects the cell
Mitochondria
Powerhouse of the cell and where respiration occurs
Ovaries
They produce and store your ovum (eggs) and they make hormones that control your menstrual cycle and pregnancy.
Uterus
The uterus also known as the womb receives a fertilised ova and protects the foetus (baby) while it grows and develops.
Embryo
An unborn animal or human being in the very early stages of development in the mothers uterus.
Foetus
An unborn offspring that develops and grows inside the uterus (womb) of humans and other mammals.
Vagina
It provides a passageway for blood and mucosal tissue from the uterus to leave the body during a menstrual period. It’s where the penis is inserted during internal fertilisation and it holds sperm until they pass into the uterus. It provides a passageway for childbirth.
Cervix
The cervix allows fluids, such as menstrual blood, to pass from the uterus into the vagina.
Cilia
Cilia moves microbes and debris up and out of the airways.
Oviduct (fallopian tube)
this tube is where fertilisation takes place. Cells in the fallopian tube transport the egg to the uterus.
Penis
The penis is the male organ used for urination and internal fertilisation. The penis is located above the scrotum. It is made of spongy tissue and blood vessels.
Urethra
The function of the male urethra is to allow passage of urine and semen.
Why do birds eggs have tiny holes in them
To allow gases and moisture to move in and out
Scrotum
The scrotum is responsible for protecting the testes. As well as this, it helps with the thermoregulation of the testicles.
Sperm duct
It carries sperm from where it is stored in the testes
Amniotic fluid
Protects the foetus from injury and temperature changes as well as permitting musculoskeletal development and acts as a shock absorber.
Umbilical cord
The umbilical cord is considered both the physical and emotional attachment between mother and fetus. This structure allows for the transfer of oxygen and nutrients from the maternal circulation into fetal circulation while simultaneously removing waste products from fetal circulation to be eliminated maternally.
Placenta
The placenta provides oxygen and nutrients to the foetus whilst removing carbon dioxide and other waste products.
