Placenta
its gets it all through the umbilical cord
Embryos excretes nitrogenous wastes into the placenta.
The developing embryo is nourished by the yolk sack until implantation. Upon implantation the placenta begins to develop, the placenta acts as the fetal lung , it transports oxygen to the fetus and carbon dioxide away from the fetus via the umbilical cord. The placenta also provides stored carbs for the developing fetus.
After puberty, the ovaries release one egg each month alternatively. The sperms enter through the vagina, travel upwards to the oviduct where they encounter the egg. If the egg is fertilized, a zygote is formed. The zygote repeatedly divided to form the embryo. This embryo trickles down to the uterus. On the uterine wall, the embryo gets implanted. The embryo gets nutrition form a special disc shaped tissue towards the uterine wall called the placenta. It contains villi on the embryo's side and provides nourishment and oxygen from the mother's blood. Waste substances such as carbon dioxide and nitrogenous wastes are taken away from the embryo. After the 9 month gestation period, the child is delivered as a result of rhythmic contractions of the uterus.
i don't know! i guuse mida!
It is considered bad luck because it wastes nourishment for the whole family.
because it supplies the body cells with the life giving materials they need for nourishment and repair;it eliminates wastes from the cells.
Not in the traditional sense, no. Sea sponges do not have digestive systems. Instead, they rely on the flow of the water they inhabit to obtain nourishment and to rid them of wastes.
wastes are removed via the placental blood system (hence the mother feels sick and vomits) the embryo doesn't defecate until it is born
how do you get the canisters in through the jundlin wastes in Lego star wars the complete saga
The kidneys remove nitrogenous wastes from the blood through filtering. The skin and liver remove other types of wastes.
Yes; they get rid of them through respiration and through their roots.
