In mammals, what is the primary purpose of the placenta?
Step 1: Understand that the placenta is an organ that forms during pregnancy in mammals.
Step 2: Know that the placenta connects the mother to the developing fetus.
Step 3: Learn that one of the main jobs of the placenta is to absorb nutrients from the mother's blood and deliver them to the fetus.
Step 4: Recognize that the placenta also helps with gas exchange, allowing oxygen to pass from the mother to the fetus and carbon dioxide to pass from the fetus to the mother.
Step 5: Remember that the placenta removes waste products from the fetus's blood, sending them back to the mother's body for disposal.
