Understanding Human Embryo Development

What is the primary function of the fetus in the later stages of pregnancy?

• To produce egg cells

• To develop and mature organs and systems

• To initiate labor

• To produce hormones for the mother

Which structure is responsible for the initial division of cells in the embryo?

• Morula

• Blastocyst

• Zygote

• Placenta

What is the primary function of the ovaries?

• To produce sperm cells

• To produce egg cells

• To nourish the developing fetus

• To transport the egg to the uterus

What is the primary function of the embryo during early development?

• To produce hormones

• To divide and form different tissues and organs

• To nourish the placenta

• To protect the fetus from teratogens

What is the morula stage in embryo development?

• A single cell formed after fertilization

• A solid ball of cells formed after several divisions

• A hollow ball of cells ready to implant

• A mature egg cell ready for fertilization

What is the primary function of the placenta during pregnancy?

• To produce egg cells

• To provide nutrients and oxygen to the fetus

• To initiate menstruation

• To protect the embryo from teratogens

What is the primary role of menstruation in the female reproductive system?

• To fertilize the egg

• To prepare the uterus for a potential pregnancy

• To produce hormones

• To transport the egg to the fallopian tubes

What is the primary function of the fallopian tubes?

• To produce hormones

• To transport the egg from the ovary to the uterus

• To nourish the developing fetus

• To protect the embryo from teratogens

What is cellular cleavage in embryo development?

• The process of fertilization

• The division of cells in the early embryo

• The formation of the placenta

• The attachment of the embryo to the uterine wall

What is the primary function of the cellular cleavage process?

• To fertilize the egg

• To divide the zygote into multiple cells

• To form the placenta

• To initiate menstruation
