Answer:
nourish the placenta
Explanation:
The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.
The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.
The USDA Animal Welfare Act takes precedence over guidelines produced by the Public Health Service, Department of Veterans Affairs and other government agencies.
The United States Department of Agriculture (USDA) has a specialized unit, called USDA Animal Care, which administers the Animal Welfare Act (AWA). AWA sets the minimum standards of care and husbandry for animals used for commercial or research purposes and public exhibitions.
