Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process can occur with almost all post-pregnancy female mammals, although it predates mammals.In humans the process of feeding milk is also called breastfeeding or nursing.rom the twenty-fourth week of pregnancy (the second and third trimesters), a woman's body produces hormones that stimulate the growth of the milk duct system in the breasts 1  : Progesterone influences the growth in size of alveoli and lobes; high levels of progesterone inhibit lactation before birth.
If you weighed 68 kg on Earth, you would only weigh 25.7 kg on Mercury. Venus is very close to Earth in size and mass. Venusâ mass is roughly 90% of the mass of the Earth. Thus, it is no surprise that someone would weigh a similar amount on Venus.
Jupiter has the most gravity in the solar systym so you would be heavier.   Jupiter is the most massive planet in the solar system. The gravity on Jupiter is around 2.5 tim â¦ es that of Earth so you would weigh 2.5 times more there. Your mass would remain the same though because the amount of stuff that is in your body doesn't change, ie you would still need the same size in jeans. Jupiter is a gas giant so you wouldn't be able to stand on its surface any way.
