w/Lab Exam Q&A | Portage Learning
These are original practice questions written for study. They are not official BIOL 252,
Portage Learning, or university exam questions and are not copied from any
copyrighted question bank. They cover common BIOL 252 Module 8 | Human Anatomy
& Physiology II topics, including development, heredity, aging, and integration of body
systems, with NCLEX-style clinical framing.
Question 1:
Which process describes the union of sperm and egg?
A. Fertilization
B. Implantation
C. Ovulation
D. Cleavage
Correct answer: A
Rationale: Fertilization is the union of sperm and egg, forming a zygote.
Question 2:
Where does fertilization typically occur?
A. Uterus
B. Ovary
C. Fallopian tube
D. Vagina
Correct answer: C
Rationale: Fertilization typically occurs in the fallopian tube (ampulla).
Question 3:
A zygote is best described as:
A. A fertilized egg
B. An unfertilized egg
C. A sperm cell
D. A blastocyst
Correct answer: A
Rationale: A zygote is the diploid cell formed by fertilization.
,Question 4:
Which process describes the rapid cell division after fertilization?
A. Meiosis
B. Cleavage
C. Implantation
D. Gastrulation
Correct answer: B
Rationale: Cleavage is rapid mitotic division of the zygote.
Question 5:
The blastocyst implants in the:
A. Ovary
B. Fallopian tube
C. Endometrium
D. Cervix
Correct answer: C
Rationale: The blastocyst implants in the endometrium of the uterus.
Question 6:
Which germ layer forms the nervous system?
A. Ectoderm
B. Mesoderm
C. Endoderm
D. Blastocyst
Correct answer: A
Rationale: The ectoderm forms the nervous system, epidermis, and related structures.
Question 7:
Which germ layer forms muscle and bone?
A. Ectoderm
B. Mesoderm
C. Endoderm
D. Trophoblast
, Correct answer: B
Rationale: The mesoderm forms muscle, bone, cartilage, and circulatory structures.
Question 8:
Which germ layer forms the lining of the digestive tract?
A. Ectoderm
B. Mesoderm
C. Endoderm
D. Blastocyst
Correct answer: C
Rationale: The endoderm forms the lining of the digestive and respiratory tracts.
Question 9:
Which structure connects the fetus to the placenta?
A. Amnion
B. Umbilical cord
C. Chorion
D. Cervix
Correct answer: B
Rationale: The umbilical cord connects the fetus to the placenta for nutrient and gas
exchange.
Question 10:
Which blood vessel in the umbilical cord carries oxygenated blood to the fetus?
A. Umbilical artery
B. Umbilical vein
C. Aorta
D. Pulmonary artery
Correct answer: B
Rationale: The umbilical vein carries oxygenated blood from the placenta to the fetus.
Question 11:
Which fetal structure bypasses the lungs?
