Answer:
(2) exchange food, oxygen, and waste between
mother and fetus
Explanation:
In most mammals like humans, the fetus produced as a result of the fertilization of the sperm and egg, develops in the uterus or womb of the female. However, this developing fetus cannot yet fend for what it requires for survival and is still dependent on the mother e.g nutrients, oxygen etc. How do this substances get to the fetus? Here comes the role of the PLACENTA.
Placenta is an organ in the uterus that serves as a connection between the mother and the fetus in her womb. The placenta enables the mother to pass digested nutrients to the fetus and exchange gases (oxygen and Carbondioxide) between them via the umbilical cord. The placenta also enables the mother remove waste produced by the fetus into her bloodstream.
The tracing of uterine activity measured with a solid-tipped intrauterine pressure catheter (IUPC) depicts no contractions. However, you are palpating contractions that are strong in intensity with a frequency of every 3 minutes and a duration of 60 seconds. A possible cause for this finding is (select an answer): The connections to the system are not connected.
An IUPC counts the number, length, and force of contractions. During palpations peaks of strong intensity is recored.As in this case IUPC seems to be not connected as its near impossible to get no contractions when palpation are high.
And one unit is the amount of pressure required to raise a mercury column by one millimetre. The intensity of the contraction is assessed from the baseline (when the uterus is relaxed) to the rise of the contraction and is recorded in units. According to studies, after spontaneous labour, 200 units of contractions per 10 minutes are typically sufficient for vaginal birth.
