Reproductive System

Question 1

Asexual reproduction

Answer 1

1 parent cell
no sperm or egg
offspring genetically identical to parent

Question 2

3 types of asexual reproduction

Answer 2

binary fission
budding
regeneration

Question 3

Sexual reproduction

Answer 3

Exchange of DNA involved between 2 parents
off springs are mix of parents
variation is an advantage for these species

Question 4

conjunction

Answer 4

exchange of DNA

Question 5

Ferdilization

Answer 5

Joining of sperm and egg or gametes

Question 6

Gametogenisis

Answer 6

Formation of gametes meiotic cell division

Question 7

Answer 7

bladder
penis
testes
scrotum
urethra
sperm duct
prostate

Question 8

sperm

Answer 8

produced in testes
travels up sperm duct
fluid added (semen)
released through urethra

Question 9

female reproductive system

Answer 9

ovary
uterus
cervix
vagina
urethra
bladder
Fallopian tube

Question 10

ovary

Answer 10

contains and releases eggs

Question 11

Fallopian tube

Answer 11

where fertilization occurs

Question 12

uterus

Answer 12

Site for fetal development

Question 13

vigina

Answer 13

birth cannal

Question 14

puberty

Answer 14

Sex hormones in both male and females are released resulting in secondary sex characteristics developing. Menstruating begins. Age 10-16

Question 15

Menopause

Answer 15

The ceasing of the menstrual cycle. Somewhere around 50 years old

Question 16

Menstrual cycle duration

Answer 16

28 day cycle

Question 17

Menstrual cycle involved hormones

Answer 17

FSH - follicle growth and ovulation, pituitary gland
LH - follicle growth and ovulation, pituitary gland
Progesterone - Lining of the uterus
Estrogen - lining of the uterus and ovulation

Question 18

cleavage

Answer 18

mitotic cell division

Question 19

ovulation

Answer 19

egg released from follicle into fulpian tube

Question 20

Implantation

Answer 20

egg goes into uterine lining

Question 21

Embryonic Development

Answer 21

1.) Zygote - fertilized egg
2.) Cleavage - mitotic cell division
3.) Blastula - Hollow ball of cells
4.) Gastrulation - Three germ layers form
5.) Diffrentation - proteins activate some genes to become specilized and form organs

Question 22

Differentiation

Answer 22

three layers begin to syntheisze diffrent proteins to activate diffrent genes to form organs

Question 23

Embryo

Answer 23

Human offspring (weeks 2-8)

Question 24

Zygote

Answer 24

fertilized egg undergoes rapid mitosis

Question 25

Fetus

Answer 25

human offspring

Question 26

Placenta

Answer 26

where the nutrients coming from the mother's bloodstream diffuses into the child's bloodstream

Question 27

Umbilical cord

Answer 27

connects the fetus to the placenta

Question 28

cervix

Answer 28

dilates through labor to allow delivery

Question 29

Amniotic sac

Answer 29

filled with fluid to cushion the fetus

Question 30

Months 1-3

Answer 30

Most of the organs are developed. Umbilical cord and sac are formed.

Question 31

Months 4-6

Answer 31

tissue are becoming more complex and heart beat can be heard

Question 32

Months 7-9

Answer 32

mostly growth and lungs become read for the baby to breath on their own

Question 33

Gestation

Answer 33

time it takes for a fetus to fully develop to human (40 weeks)

Question 34

Labor and delivery

Answer 34

hormone Oxycontin released which stimulates uterine muscles to contract (labor). Cervix dilates and than the baby is delivered through the vagina.

Question 35

Luteal phase

Answer 35

after the egg is released from the ovary, the follicle is turned into the corpus luteum (a big yellow ball of cells) corpus luteam disapears if egg not fertilized

Question 36

polar bodies

Answer 36

Small haploid cell formed at the same time as egg cell (female, meiosis)

Question 37

Risk of when mother is smoking while carrining a fetus after birth

Answer 37

low birth weight

Question 38

vas deferens

Answer 38

Transports semen

Question 39

interior fertilization

Answer 39

Sperm fertilizes egg inside the female, 1 egg fertilized

Question 40

exterior fertilization

Answer 40

Many eggs fertilized not inside the female

Question 41

Blastocyst

Answer 41

Ball of cells with a fluid-filled cavity inside.
