REPRODUCTIVE
Which is a similarity between innate immunity and adaptive immunity? - Answers -
Leukocytes and cytokines are active in both.
Hemophilia, color blindness, and Duchenne muscular dystrophy occur more often in
males than females. Why? - Answers -These traits are carried on the X chromosome,
and since there is no matching gene on the Y chromosome, the traits are expressed
more often in males.
The cervix is - Answers -the neck of the uterus only.
Polyspermy in humans results in - Answers -a nonfunctional zygote.
A sample of tissue from an injury shows a large number of basophils. This would
indicate that the tissue was - Answers -inflamed
Which of the following is a similarity between the spleen and lymph nodes? - Answers
-Both are sites where foreign invaders are recognized by immune cells.
By which mechanism do natural killer (NK) cells destroy virally infected cells? -
Answers -Induction of apoptosis
Apoptosis - Answers -process of programmed cell death
Which is responsible for sweeping the ovulated egg toward the Fallopian tube and away
from the abdominal cavity? - Answers -fimbriae
Fimbriae - Answers -Fingerlike projection of the uterin (fallopian) tubes that drape over
the ovary.
myometrium of uterus - Answers -the thick wall of the uterus consisting of smooth
muscle and connective tissue
Which acts as first line of defense against pathogens? - Answers -skin
What is the role of human chorionic gonadotropin (hCG)? - Answers -It causes the
corpus luteum to continue to secrete progesterone.
The role of the pituitary hormone FSH in males is to - Answers -initiate sperm
production in the testes.
, Which embryonic structure gives rise to the seminal vesicles and vas deferens during
fetal differentiation into a male? - Answers -Wolffian duct
Bipotential gonad - Answers -the gonad of the developing embryo that is capable of
differentiating along two developmental pathways toward the development of either a
testis or the ovary
Müllerian duct - Answers -a duct system in the embryo that will develop into female
reproductive structures (oviducts, uterus, and upper vagina) if androgens are not
present
Wolffian duct - Answers -one of a pair of structures in the embryo that, when exposed
to testosterone, will develop into the male reproductive system
forms epididymis, ductus deferens, and seminal vesicles
Which enzyme converts androgens to estrogens, and where is it found? - Answers -
Aromatase, found in the ovaries and the testes
Aromatase - Answers -enzyme that converts testosterone to estradiol
Progestin - Answers -female hormone that stimulates the uterine lining during
pregnancy and is also used in treatment of abnormal uterine bleeding and for hormone
replacement therapy
Kisspeptin - Answers -A hypothalamic peptide hormone that increases gonadotropin
secretion by facilitating the release of gonadotropin-releasing hormone.
Estradiol - Answers -estrogen secreted by the ovaries
Which disease is fought by the immune system as part of its function to recognize and
remove abnormal "self" cells? - Answers -Cancer
Opsonins function by - Answers -marking or tagging pathogens so phagocytes can find
and ingest them.
Autoimmune diseases are an example of a(n) ________ response by the immune
system. - Answers -incorrect
Which is NOT a characteristic of adaptive immunity?
acquired immunity
nonspecific immunity
cell-mediated immunity
humoral immunity - Answers -nonspecific immunity
