What are the roles of hCG, hPL, and relaxin during pregnancy?
Understand the Problem
The question is asking about the anatomical features and physiological aspects of pregnancy as depicted in the image, which includes a diagram of a human fetus within the uterus and discusses specific hormones and their roles during pregnancy.
Answer
hCG maintains progesterone; hPL provides nutrition and prepares milk glands; relaxin softens cervix and relaxes ligaments.
The roles of hCG, hPL, and relaxin during pregnancy are: hCG maintains progesterone production by the corpus luteum; hPL helps provide nutrition to the fetus and prepares the mammary glands; relaxin softens and widens the cervix, and relaxes pelvic ligaments.
Answer for screen readers
The roles of hCG, hPL, and relaxin during pregnancy are: hCG maintains progesterone production by the corpus luteum; hPL helps provide nutrition to the fetus and prepares the mammary glands; relaxin softens and widens the cervix, and relaxes pelvic ligaments.
More Information
hCG is crucial during early pregnancy for maintaining the corpus luteum, hPL promotes fetal growth by regulating maternal metabolism, and relaxin makes childbirth easier by loosening ligaments and expanding the pelvis.
Tips
Confusion can arise differentiating these hormones; remember that hCG is early pregnancy-focused, hPL supports fetal nutrition and lactation, and relaxin prepares for labor.
