Reproductive System

Question 1

sperm structure

Answer 1

head
-haploid nucleus
-acrosome 
neck
-contains mitochondria to supply ATP for movement
flagellum 
-locomotion

Question 2

hepatitis

Answer 2

hep a
-water with fecal material
-oral/anal contact
hep b
-sexual contact with infected body fluids/blood
hep c
-blood to blood contact with infected needles/syringes

Question 3

vulva parts

Answer 3

• clitoris
• labia majora
• labia minora

Question 4

fructose

Answer 4

-after ejaculation the mitochondria process fructose in seminal fluid to provide energy

Question 5

fertilization site

Answer 5

Fallopian tubes

Question 6

viral stis

Answer 6

• HIV/AIDS
• hepatitis a/b/c
• genital herpes
• HPV

Question 7

endometrium

Answer 7

• lining of the uterus

- richly supplies with blood vessels to provide nutrients for the fetus

Question 8

acrosome

Answer 8

• cap like structure covering head
• stores enzymes that are needed to penetrate the protective layer surrounding a female egg
• needed in order to fertilize

Question 9

HIV

Answer 9

• attacks helper T cells

- as helper T cells decrease the infected person because more vulnerable to disease

Question 10

secondary sexual characteristics

Answer 10

distinct set of features that aren’t directly related to reproductive system

male
-facial/body hair -deeper voice -broader shoulders

females
-minimal facial/body hair -prominent breasts -higher voice

Question 11

amniotic fluid

Answer 11

watery fluid in the amnion that:

• cushions embryo against jolts
• controls fetal body temp
• prevents amnion from sticking to embryo/fetus

Question 12

chorionic villi

Answer 12

-enlarge on the side of the chorion which implants into the endometrium; these villi become part of the placenta

Question 13

chlamydia

Answer 13

• caused by the bacterium chlamydia trachomatis
• discharge from penis/vagina
• burning pain when urinating
• fever
• asymptomatic

Question 14

pid

Answer 14

• if chlamydia isn’t detected it can spread to cervix and fallopian tubes and lead to pid
• very painful and can result in a build up of scar tissue in the fallopian tubes
• tubes become blocked causing infertility
• infection in cervix can cause open sores that increase risk of HIV
• baby who comes in contact with it can develop infections of the eyes and respiratory tract

Question 15

ordering male structures

Answer 15

• seminiferous tubules
• epididymis
• vas deferens
• ejaculatory duct

Question 16

temp for sperm

Answer 16

35 degrees celsius

Question 17

ectopic pregnancy

Answer 17

-fetus develops outside the uterus (inside fallopian tubes)

Question 18

interstitial cells

Answer 18

• lie between the seminiferous tubules

- secrete testosterone

Question 19

seminiferous tubules

Answer 19

-long coiled tubes that compose the testes

Question 20

epididymis

Answer 20

• sperm are transported here

- sperm mature and become motile

Question 21

female hormones

Answer 21

• progesterone
• FSH
• LH
• estrogen??

Question 22

oviduct cilia

Answer 22

• thread like projections called fimbriae continually sweep over the ovary
• when 2 oocyte is released its swept by fimbriae into a cilia lined tube called a fallopian tube

Question 23

placenta

Answer 23

• CO2/wastes from the baby are exchanged for O2/nutrients for the mother
• baby’s and moms blood don’t mix
• secretes HCG (human chorionic gonadotropin)
