Embryo

protect the baby throughout the prenatal period. All though all three of the supporting structures are important, but the placenta is mainly the most important. The placenta provides the exchange of waste and nutrients between the mother and embryo. The mother and embryo don’t share the same blood, which is the make reason for placenta. Understanding Human Development states “the placenta permits the exchange of nutritive and waste materials by diffusion across cell membranes, normally without…

The debate on Animal and Human Cloning is being debated on like the debates on abortions. Cloning humans some believe it should be legal, and on the other hand some think it unacceptable. Some Doctor Scientist would like to utilize cloning animals for research purposes. There are different types of debates pertaining to each individual perspectives including their religious beliefs. Christian belief wouldn’t recommend cloning because humans are a gift from God, and all things are created in God…

Embryonic stem cells have the ability to multiply and replace diseased cells. They can be changed to have properties of different cells. However, these embryos have the potential to grow into human beings, and by extracting them for their stem cells, scientists destroy the embryo. Scientist’s ultimate goal may be to help people, but hundreds of embryos are destroyed on the way to finding these cures. Although embryonic stem cell research has been shown to have great medical potential, there…

This study pertains to the health of women and embryo, preconception and during pregnancy, when exposed to potentially teratogenic drugs. Stated in the introduction of the study, teratogenic drugs may in fact pose a major threat to the embryo due to its destructive nature in some cases. These drugs are capable of causing abnormal changes to the normal growth of the embryo or fetus, thus leading to improper function and/or structure. At such early stages of growth, these changes are almost…

belief that an embryo is actually human, and that it should be treated just like human life, and this happens as soon as an egg is fertilized.” (Stem Cells) And while this is fundamentally true, stem cell researchers do not kill embryos for their stem cells. The embryos used do not make it to term due to health issues or the parent’s decide to abort. People against stem cell research do not research and therefore present poor arguments, such as stem cell researchers kill the embryos for the…

A teratogen is any substance such as a chemical, medication, radiation, virus or infection, etc., that can cause malformation of an embryo. Teratogens can be found anywhere, such as your own home or workplace. It is proven that “teratogens are thought to have the ability to affect the fetus about 10 to14 days after conception” (“Teratogens”, n.d.). The harmful effects are “influenced by fetal genetic vulnerability, type and amount of teratogen, and timing of the exposure during pregnancy”…

Potter Stewart once said, “Ethics is knowing the difference between what you have a right to do and what is right to do.” In the article,”Of Headless Mice…and Men” by Charles Krauthammer, it explains how it is unethical for scientists to create human clones for the sole purpose of disemboweling the body for personal needs. These human clones would be human in every form and way, however, a scientist would remove the forebrain. Although the cloning of humans would be promising for people's health…

affiliated with this topic because people are using human embryos for science. I entirely agree with Dr. Garman about the problem with stem cell research and that certain laws are put up that help the use of stem cells in an ethical way. I also agree that stem cell research should have controversy affiliated with it as well. Even though I am entirely for stem cell research I see the other side of the controversy: scientists are using embryos which is where all humans once came from for a science…

Bioethical Debate: Stem Cells Ella Reich 1˚ AP Biology, Carlmont High School Introduction The possible uses of stem cells are a very controversial topic in modern biology and medicinal science. Stem cells are unspecialized body cells that have the ability to grow and develop into many various types of cells in the body. For example, a single stem cell has the potential to develop into a blood cell, a brain cell, a tissue cell, a muscle cell, or several other specialized cells. Stem cells…

13-year-old girl in California declared brain dead, the pregnant woman in Texas who was declared brain dead and the hospital obeying the law to keep her on life support to get the baby to an age to deliver, the issues or reproductive technology---how many embryo to implant, genetic disposition (getting a baby with blue eyes and an IQ of 175), abortion, and the large issue of alcohol or drug impaired nurses (and doctors). What are your thoughts on these topics and any others you can think of…
