Which cells secrete the enzymes for make implantation of embryo possible?
Trophoblast cells secrete enzymes that facilitate the implantation of the embryo into the uterine wall. These enzymes break down the endometrial lining, allowing the embryo to embed itself securely into the uterus, which is essential for successful pregnancy.
In humans after implantation what is the elaborate projection developed from trophoblast called?
After implantation, the trophoblast develops elaborate projections called chorionic villi. These villi extend into the maternal tissue and help in the formation of the placenta by facilitating nutrient and gas exchange between the mother and the developing embryo.
In human’s embryonic development chorionic villi which-operate with the tissue of the mother’s uterus to forms ...
The chorionic villi, which are projections from the trophoblast, cooperate with the tissue of the mother's uterus to form the placenta. The placenta is a critical structure that supports the developing embryo by providing nutrients and oxygen and removing waste products.
Function of the placenta is ...
The placenta has multiple functions that are essential for the development of the embryo. It delivers nutrients and oxygen to the embryo, and it removes waste products from the embryonic blood. Thus, the correct answer is 'all of these'.
Which part present between placenta and embryo?
The umbilical cord is the part that connects the embryo (or fetus) to the placenta. It functions as the conduit through which nutrients and oxygen are delivered to the embryo and waste products are removed.
Which hormones are not produced by placenta?
Placenta produces hormones like hcG, hcL and estrogen
The signals for parturition originate from
The signals for parturition (childbirth) originate from both the fully developed fetus and the placenta. The fetus produces hormones that signal the placenta, which in turn releases hormones to initiate labor.
After delivery mammary gland start producing milk, in milk which necessary substance is present for immunity?
After delivery, the mammary glands start producing milk, which contains antibodies. These antibodies are crucial for providing immunity to the newborn, helping to protect them from infections and diseases.
