Exploring Separation of the Cord and Fetus in Animals

In summary, the placenta and cord are an extension of the fetus and contain the fetus's DNA. However, in cases of diabetes, it can also reflect the mother's genes. Animals typically deal with the separation of the cord from the fetus by having the mother break and consume the cord, which helps to prevent bleeding. This is different from humans, where the cord must be cauterized to prevent bleeding since newborns do not have a clotting factor. Animals may have a more proactive clotting rate, as the mother's actions help to stop the bleeding after the cord is separated.

1] Is the placenta and cord an extension of the fetus or of the host? We were talking about this, and have tentatively concluded that the DNA of placenta and cord would reflect the fetus rather than the host.

This came up in a discussion about 'two vessel cord'. I was wondering if that would be an anomaly of the mother's or of the baby's genes.


2] How do animals deal with the separation of the cord from the fetus? I know the mother will break the cxord and consume the products of labour, but that doesn't directly cauterize or clot the baby. In (modern) humans we must cauterize the cord or it will bleed out, since newborns do not have a clotting factor. Do animals have a more "proactive" clotting rate?

1] it is of the fetus. It is an anomaly of both the fetus and the mother, since diabetes can significantly increase the risk.

Depending on which species you are discussing it can be primarily fetal or about 50% fetal/50% maternal. If you do a google search for "placental structure" and related terms you'll find more info. Here were a few I found, http://arbl.cvmbs.colostate.edu/hbooks/pathphys/reprod/placenta/structure.html" (human only).

The umbilical cord is usually chewed by the mother after she cleaned the newborn. By that time, the umbilical cord does not function anymore and blood will not come out. Human seems to be the exception.
 

Related to Exploring Separation of the Cord and Fetus in Animals

1. What is the purpose of exploring separation of the cord and fetus in animals?

The purpose of this exploration is to gain a better understanding of how the process of cord separation occurs in different animal species. This can provide insights into potential developmental or evolutionary differences and help us better understand the anatomy and physiology of these animals.

2. How does the cord separate from the fetus in different animal species?

The process of cord separation can vary among different animal species. In some species, the cord may be physically broken or chewed off by the mother, while in others it may detach naturally after a certain period of time. Additionally, the composition and structure of the cord may also differ among species.

3. Are there any potential risks or complications associated with cord separation in animals?

In some cases, complications such as infections or hemorrhaging may occur during the process of cord separation. These can be more common in animals that have a more invasive separation process, such as those that require the mother to physically break the cord. However, in most cases, the separation process occurs smoothly without any major issues.

4. Are there any factors that can affect the timing of cord separation in animals?

The timing of cord separation can be influenced by a variety of factors, including the species of the animal, the size and weight of the newborn, and the environmental conditions. Additionally, the presence of certain hormones or enzymes can also play a role in initiating the separation process.

5. How can the exploration of cord separation in animals benefit human research?

Studying the process of cord separation in animals can provide valuable insights for human research, particularly in the field of obstetrics and gynecology. Understanding the mechanisms and factors involved in this process can help improve our understanding of human fetal development and potentially lead to advancements in medical treatments and interventions.
