Q

oviduct

A

(fallopian tube) tube that carries eggs where fertilization occurs

22
Q

uterus

A

site where embryo implants and develops

23
Q

cervix

A

outer end of the uterus

24
Q

vagina

A

birth canal that leads to the outside of the body

25
Q

menstrul cycle

A

a cycle of ovulation implantation then shedding of the unterine line

26
Q

stages involved w menstrual cycle

A

folice stage –> ovulation –> curpus lutem –> menstrution

27
Q

meiosis

A

is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information

28
Q

haploid

A

half the # of chromosomes

29
Q

diploid

A

a condition where a nucleus contains the full amount of chromosomes

30
Q

homologus

A

same

31
Q

homologous chromosomes

A

a pair of chromosomes that have the same gene during meiosis, this is called crossing over

32
Q

by the chromosomes crossing over the chromosomes swap increasing_____

A

genetic variation

33
Q

gametogenesis

A

proccess of making gametes (sex cells)

34
Q

spermatogenesis

A

making sperm

35
Q

oogenesis

A

making eggs

36
Q

fertilization

A

the proccess of a sperm joining an egg occurs in the OVIDUCT (fallopian tube) of the female

37
Q

embryo

A

CLEVAGE –> GASTRULATION –> GROWTH & DIFFERENCIATION

38
Q

clevage

A

a series of mitiosis divisions

39
Q

differentiation

A

cells of the developing zygote become different cells from the body cells using mitosis to become different body cells

40
Q

amneotic sad/fluid

A

provides protection and coshing

41
Q

placenta

A

provides nutrients and gas exchange for the fetus

42
Q

unbilical birth

A

attaches baby to placenta

43
Q

zygote

A

a diploid cell resulting from the fusion of two haploid gametes

44
Q

sperm

A

Sperm is the male reproductive cell, or gamete, in forms of sexual reproduction

45
Q

Eggs

A

are made in the ovaries

46
Q

The differences between mitosis and meiosis

A

Mitosis is where the genetic material is equally divided into two new daughter cells where meiosis is where a single cell divides twice two produce 4 cells containing half the original amount of genetic info

47
Q

What the resulting cell of fertilization is called.

A

This is called the zygote

48
Q

Where fertilization occurs and what happens during the process.

A

Fertlllzation occurs in the fallopian tube, this is when the egg and sperm join together

49
Q

The major events that occur during the menstrual cycle.

A

Folice stage – ovulation — corpus lutem — mestration

50
Q

What would happen if the fallopian tubes or vas deferens were blocked?

A

The sperm would not be able to get through so the egg wouldnt be able to be fertlilized
