Problems involving the formation of the chorion would affect
(a) The embryo’s ability to produce blood cells
(b) The formation of limbs
(c) The embryo’s ability to derive nutrition from the mother
(d) Lung formation
(e) The urinary system
Guida verificata passo dopo passo1
Step 1: Understand the role of the chorion in embryonic development. The chorion is one of the extraembryonic membranes that contributes to forming the placenta, which is essential for nutrient and gas exchange between the mother and the embryo.
Step 2: Recognize that the chorion's primary function is related to supporting the embryo by facilitating the transfer of nutrients and oxygen from the mother to the developing embryo, rather than directly forming embryonic tissues like limbs, lungs, or the urinary system.
Step 3: Analyze each option in the problem: (a) blood cell production is mainly from the yolk sac and later fetal liver and bone marrow; (b) limb formation is a function of the embryo's mesoderm; (c) nutrition from the mother is linked to the placenta, which involves the chorion; (d) lung formation is part of the embryo's endodermal development; (e) the urinary system develops from the mesoderm.
Step 4: Conclude that problems with the chorion would most directly affect the embryo's ability to derive nutrition from the mother, since the chorion is integral to placenta formation and nutrient exchange.
Step 5: Therefore, the correct focus is on the function related to maternal-fetal nutrient transfer, which corresponds to option (c).

Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Chorion and Its Role in Embryonic Development
The chorion is an extraembryonic membrane that contributes to forming the placenta, facilitating nutrient and gas exchange between the mother and embryo. It surrounds the embryo and other membranes, playing a crucial role in supporting embryonic growth by enabling maternal-fetal nutrient transfer.

Placenta Formation and Maternal-Fetal Nutrition
The placenta develops partly from the chorion and is essential for providing oxygen and nutrients to the embryo while removing waste. Problems in chorion formation can impair placental function, leading to inadequate nutrition and oxygen supply to the developing embryo.

Embryonic Structures Derived from the Chorion
Unlike organs such as limbs, lungs, or the urinary system, which develop from the embryo's germ layers, the chorion is an extraembryonic structure. Its primary function is not organogenesis but supporting the embryo through nutrient exchange, so defects mainly affect embryonic nutrition rather than direct organ formation.
