Which is a similarity between innate immunity and adaptive immunity? - correct answer ✔✔
Leukocytes and cytokines are active in both.
Hemophilia, color blindness, and Duchenne muscular dystrophy occur more often in males than
females. Why? - correct answer ✔✔ 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 - correct answer ✔✔ the neck of the uterus only.
Polyspermy in humans results in - correct answer ✔✔ a nonfunctional zygote.
A sample of tissue from an injury shows a large number of basophils. This would indicate that
the tissue was - correct answer ✔✔ inflamed
Which of the following is a similarity between the spleen and lymph nodes? - correct answer
✔✔ Both are sites where foreign invaders are recognized by immune cells.
By which mechanism do natural killer (NK) cells destroy virally infected cells? - correct answer
✔✔ Induction of apoptosis
Apoptosis - correct answer ✔✔ process of programmed cell death
, Which is responsible for sweeping the ovulated egg toward the Fallopian tube and away from
the abdominal cavity? - correct answer ✔✔ fimbriae
Fimbriae - correct answer ✔✔ Fingerlike projection of the uterin (fallopian) tubes that drape
over the ovary.
myometrium of uterus - correct answer ✔✔ the thick wall of the uterus consisting of smooth
muscle and connective tissue
Which acts as first line of defense against pathogens? - correct answer ✔✔ skin
What is the role of human chorionic gonadotropin (hCG)? - correct answer ✔✔ It causes the
corpus luteum to continue to secrete progesterone.
The role of the pituitary hormone FSH in males is to - correct answer ✔✔ initiate sperm
production in the testes.
Which embryonic structure gives rise to the seminal vesicles and vas deferens during fetal
differentiation into a male? - correct answer ✔✔ Wolffian duct
Bipotential gonad - correct answer ✔✔ 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 - correct answer ✔✔ 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 - correct answer ✔✔ one of a pair of structures in the embryo that, when
exposed to testosterone, will develop into the male reproductive system
