Not all animals have placentas because they lay eggs instead. Only mammals have placentas by the way. Other animals use eggs and amniotic eggs.
Animals that do not develop in a placenta will develop outside of the uterus rather than in. Kangaroos and Koalas use pouches to develop their young.
All known animals need a shelter of some form.
yes
Placental animals give birth to live young that have been nourished in the womb by the placenta.
plants need soil and animals need food
they us the placenta as base for some of the components in their circuit boards.
Placenta previa is a term used to describe a situation involving the placenta being attached to the wall of the uterus close to the cervix. Sometimes, placenta previa can have no symptoms, but some of the most commonly experienced symptoms are cramps and bleeding during pregnancy.
Most do. Some desert animals get all the moisture they need from their diet.No.
This varies widely depending upon the species and the individual. I'll give three examples: humans, cows and horses. From the water breaking to the placenta being discharged, some human females can take as little as 2 hours while other females are in labor for 2 days. In cattle, from the water breaking to the placenta being discharged, some cows can clear the calf and placenta in 3 hours, while other cows may retain the placenta for 4 days. In horses, from the water breaking to the placenta being discharged, a mare needs to get everything done within about 6 hours or she is in a life-threatening medical emergency.
I LOST PART OF MY PLACENTA 4 WEEKS AFTER GIVING BIRTH SO I THINK YOU SHOULD GET THIS CHECKED ASAP AS YOU WILL NEED A DNC IT IS POSSIBLE FOR PARTS TO GET LEFT AS IT STICKS
Yes! Unbelievably some people who believe certain things do eat the placenta after the baby is born! ergh!
The placenta is some times called the 'after birth' as it is expelled from the uterus after the baby is born.
