Questions and Answers

What is the main function of the umbilical cord in the development of the fetus?

  • Assisting in the development of the fetal nervous system
  • Providing a connection between the fetus and the placenta for nutrient exchange (correct)
  • Producing hormones for fetal development
  • Aiding in the formation of the fetus's internal organs

  • Prostate gland
  • Sperm ducts
  • Testes (correct)
  • Scrotum

What is the main function of the cervix in the female reproductive system?

  • Production of hormones for pregnancy
  • Providing a passageway for sperm to reach the egg
  • Protecting the uterus from infections (correct)

Match the following parts of the male reproductive system with their functions:

<p>Testes = Production of sperm and testosterone Scrotum = Regulation of temperature for sperm production Sperm ducts = Transport of sperm from testes to urethra Prostate gland = Secretion of fluid for sperm motility</p> Signup and view all the answers

Match the following parts of the female reproductive system with their functions:

<p>Ovaries = Production of eggs and hormones like estrogen Oviducts = Site of fertilization and transport of egg to uterus Uterus = Implantation of fertilized egg and development of fetus Cervix = Opening between vagina and uterus, allowing sperm entry and baby exit</p> Signup and view all the answers

Match the following adaptations of sperm with their functions:

<p>Flagellum = Provides motility for sperm to reach egg Mitochondria = Generates energy for sperm movement Enzymes in the acrosome = Aids in penetration of egg during fertilization Nucleus = Contains genetic material for fertilization</p> Signup and view all the answers

Match the following adaptations of egg cells with their functions:

<p>Energy stores = Provide nutrients for early embryo development Jelly coat = Protects egg and changes to prevent polyspermy during fertilization Cell membrane = Regulates which substances enter and exit the egg cell Cytoplasm = Contains organelles necessary for early embryonic development</p> Signup and view all the answers

Match the following features of male and female gametes:

<p>Size = Sperm are smaller than eggs Structure = Eggs have more organelles compared to sperm Motility = Sperm are flagellated and motile, while eggs are non-motile Numbers produced = Sperm are produced in large numbers compared to eggs</p> Signup and view all the answers

Match the following parts in fetal development with their functions:

<p>Umbilical cord = Connects fetus to placenta for nutrient and waste exchange Placenta = Facilitates exchange of nutrients, gases, and waste between mother and fetus Amniotic sac = Protects fetus by containing amniotic fluid for cushioning Amniotic fluid = Protects fetus from mechanical injury and helps maintain constant temperature</p> Signup and view all the answers

Match the following in relation to placenta and umbilical cord function:

<p>Placenta function = Allows exchange of dissolved nutrients, gases, and waste between mother's and fetus' bloodstreams Umbilical cord function = Transfers nutrients and oxygen from mother's blood to fetus while removing waste products Placenta structure = Contains villi that increase surface area for efficient exchange Umbilical cord structure = Contains blood vessels connecting fetus to placenta</p> Signup and view all the answers

Match the following with their effects on the fetus:

<p>Pathogens passing across placenta = Can cause infections or developmental issues in fetus Toxins crossing placenta barrier = May lead to birth defects or health problems in the developing baby Fetal exposure to harmful substances via placenta = Can result in long-term health complications for the child Placental permeability to external agents = Allows substances to cross that can impact fetal growth and development</p> Signup and view all the answers
