Alveoli |
where gas exchange between lungs and blood takeplace |
|
|
Zygote |
the cell created when sperm and egg combine |
|
|
Fertilisation |
when the two gametes meet to create a zygote |
|
|
IVF |
in vitro fertilisation and surrogacy are options for couples struggling to create a baby. IVF is when the baby is fertilised externally |
|
|
Capillaries |
These infiltrate body tissue and reach the working cells |
|
|
Diffusion |
Gas exchange- it’sthe process of more condensed gases spreading out to a less condensed place.Because of this, it means that cell waste and oxygen can be delivered fromcells to bloodstream and bloodstream to cells. |
|
|
Parthenogenesis |
Some animals are able to create offspring/ get pregnant without needing a malereproductive organ, just a female one |
|
|
Budding |
Form of asexual reproduction involving one parent. Some simplistic animals can create 'buds' which can grow of the parent, they grow into an identical offspring |
|
|
VegetativePropagation |
Similar to budding but with some vegetables. The identical copies generally grow off the stem of the plant |
|
|
Plasma |
The liquid thatblood is suspended in |
|
|
RedBloodCells |
Carry oxygen aroundthe blood vessels and go through the heart to the lungs to get replenished anddrop off wastes |
|
|
WhiteBloodCells |

It can't have A because itdoesn't have A and it can't have B because it doesn't have B |
|
|
Arteries |
Fresh blood moving away from the heart to carry oxygen to the different body cells. Able to carry blood at high pressure |
|
|
Veins |
Veins carry cell waste (carbon) and can only pump blood at low temperature |
|
|
Testes |
produce sperm cells |
|
|
scrotum |
where the testes are located, slightly lower temperature than body temperature |
|
|
VasDeferens |
tube through which sperm travel from testes to penis |
|
|
ProstateGland |
liquid that creates semen with sperm |
|
|
SeminalVesicle |
provides energy for sperm |
|
|
Urethra |
the tube inside penis (after Vas deferens), semen leaves body from this tube |
|
|

sells during sexual arousal, muscle which ejects the semen out of the body |
|
|
Ova |
female sex cell |
|
|
ovaries |
where ova is produced |
|
|
FallopianTube |
fertilization occurs here, this is where the sperm must get to |
|
|
Uterus |
size of pear when empty, where the baby develops |
|
|
cervix |
passage way between uterus and vagina |
|
|
vagina |
where the penis is during reproduction, this is so that the semen can enter through the cervix and make its way to the Fallopian tube |
|
|
stamen |
the male part of a flower |

|
anther |
part of the stamen, it produces and holds pollen (flower sperm) |
|
|
filament |
hair like stalk that the anther sits on top of |
|
|
Pistil |
the female part of a flower |
|
|
stigma |
female- sticky bulb in the center of the flower, it receives the pollen |
|
|
style |
the stalk that the stigma sits on |
|
|
ovary |
contains ovule and is found at the bottom of a flower. this is the part of the flower that turns into fruit to eat |
|
|
ovules |
found inside the ovary, these develop into seeds |
