The placenta is the temporary association of fetus and maternal tissue. It is meant for nutrition and transport of different substances.
Explanation:
The placenta is a temporary association of fetal and maternal tissues. The placenta is formed from the trophoblast of the blastula. These trophoblasts form chorionic villi which later forms the placenta. The chorion and allantois also take part in the formation of the placenta. Hence, the human placenta is known as the chorioallantoic placenta. The process of formation of the placenta is known as placentation.
The placenta has several functions but the major function is to provide nutrition to the fetus. The developing fetus gets nutrition from the mother's body by the placenta. The placenta provided with blood vessels which help in the transportation of different substances. It also helps in gas exchange between the mother and baby. Thus it plays a vital role in fetal respiration. The metabolic wastes diffuse through the placenta. Placenta also stores fat, glycogen, which participates in protein metabolism.

Point suspension occurs when one receives too many points against driving record within a given period of time, therefore one will end up loosing his/her driving licence through an accumulation of excess points. This happens such that each time one is convicted of a driving violation the court notifies the DMV (division of motor vehicles) electronically thus keeping truck on the number of times one has made such violations. Therefore, it is true that rough estimates that point suspension of the driver's license can average between $3,000+ to $11,000+.
