Two common male cancers and their typical age of infection would be

Back 20

Front 21

The female structure that is both a gland and the site of ovum developement.

Back 21

The ovaries.

Front 22

Fertilization usually occurs in the ____________ ______ for the new life to have time to develop and implant.

Back 22

fallopian tubes

Front 23

These extentions help sweep a released egg into the fallopian tubes.

Back 23

Fimbria.

Front 24

The lining of the uterus which grows and thickens each month in preparation for a fertile egg implantation is known as the

Back 24

endometrium linning.

Front 25

The birth canal or the site of copulation is the

Back 25

vagina.

Front 26

The strong muscular ending to the uterus that hold a developing embryo inside during pregnancy is the

Back 26

cervix.

Front 27

The analogous structure to the head of the male penis, that provides simtulation in females is the

Back 27

clitoris

Front 28

The two hormones that target mammary glands in breast tissue are

Back 28

oxytocin to let the milk down and prolactin to maintain milk production.

Front 29

Oogonia do not to this kind of cellular division and therefore to not replace themsleves.

Back 29

mitosis.

Front 30

Oocytes continue the process of _______ on their way to becoming mature eggs

Back 30

meiosis.

Front 31

Meisosis in a mature ova will only finish if

Back 31

the ova is fertilized by a sperm cell.

Front 32

In contrast to male gametogenesis, female gametogenesis results in only one haploid gamete. This is because of

Back 32

unequal Cytokinesis.

This is needed to provide the new cell with the most cytoplasm as possible.

Front 33

The absence of a menstrual cycle is known as

Back 33

Amenorrhea

Front 34

Menopause in females is when ____________ _______, and usually occures around age _________.

Back 34

menstrual cycles stop,

50.

Front 35

Day 1 - 5 of the female menstral cycle iis called the __________ phase and is characterized by

Back 35

flow

a lack of hormones, causing the endometrium lining to be shed.

Front 36

Day 6 - 13 of the female menstral cycle is called the _________ phase and is characterized by

Back 36

follicular

high FSH and later estrogen levels. Ends with a spike in LH

Front 37

Day 14 of the female menstral cycle is marked by an event called

Back 37

ovulation.

Front 38

Day 15 - 28 of the female menstral cycle is called the _________ phase and is characterized by

Back 38
