That tissue is called as placenta. Both fetal and maternal blood come very close to each other here and does not mix. Blood of both is separated by very thin membrane with fairly large surface area.
tissue fluid gives their requirements in correct time
there are two types of wastes : solid , liquid . the waste not only harms on human health but it also effects
microglial cells
Clinical waste is waste which poses a threat of infection to humans. Things like - syringes and needles. Human/animal tissue. Pharmaceutical products. Its mainly from places like hospitals, vets and health clinics.
Sertoli cells extend inward from the periphery of the seminiferous tubule and provide nourishment to the spermatids as they undergo spermiogenesis. They create a protected microenvironment for the development of sperm, secrete necessary nutrients and hormones, and play a crucial role in maintaining the blood-testis barrier.
so it doesn't die
The embryo gets rid of waste when the mom feels sick and vomits.
The mother does. The embryo attaches to the uterine lining (called implantation) then secretes an enzyme to breakdown the cells of the lining as it burrows into the uterus. Maternal uterine cells then develop and surround the entire embryo, soon maternal blood vessels unite with the embryo to nourish it and remove waste products. This occurs about one week after fertilization and will provide nourishment throughout the first trimester until the embryo reaches the fetal stage at which time the placenta takes over through the umbilical cord.
The mammal embryo receives its nutrients from the mother through the placenta. The placenta allows nutrients to travel from the mother's system to the embryo's, and for waste products to leave the embryo's system so they can be disposed of by the mothers.
placenta
Piglets are mammals and as such receive there nourishment through their umbilical cord which is attached to the placenta, this is where the piglets blood exchanges waste and food with the body of the mother sow.
yes
One waste product is carbon dioxide.
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.
It excretes it into the ALLANTOIS GLAND.
through the umbilical cord
The Capillaries transfers waste filled blood from the tissues into the Pulmonary circulation.capillariesTiny blood vessels that pass food and oxygen to cells and receive waste from cells.
