Answer:
The pill, Conraceptives, IUDs, and "Pull out"
Explanation:
The pill is very effective for tracking your menstural cycle- and fetility period. It is most effective if you remeber to take it everyday, otherwise your hormose with be out of balance. Contraceptives are decent abd phycically go into the vaginal canal. It is quite painful during insertio and there is a chance it may break or come out which causes complications. IUDs are physical hormone implants in your skin inserted by a shot which is very effective if you have hormones that are out of balance. One risk is that it may break, travel through your body, or come out. The pull out method is not very effective as pre-ejaculation fluid contains small amounts of active sperms which is a risk. It is also very hard for the male to resist this urge aswell.
HLA antibodies attack foreign invaders like Viruses and bacteria. But if a person gets a donated Organ. Then the immune system does not recognize the donated organ and attack it. That is why people who have transplanted organs have to take drugs to suppress the immune system. <span />
Let's all think about "Health Sciences" for a second. If any of you don't know what this means..it pertains to the field of medical primarily. With that in mind, you NEED to have effective means of communication in this field for many reasons of which some include: patient medical record accuracy, medication accuracy, diagnosis accuracy.
You wouldn't want to go into the emergency room at the hospital because you broke your toe and then all the sudden you are being taken to surgery for a procedure that is taking place on you left L5-S1 (lumbosacral spine). Or perhaps due to inadequate communication processes you could accidently be billed for a procedure that you didn't have and the next thing you know you have a bill in the mail from your health insurance provider stating you owe $23,000 for the procedure that they did not cover. Things like this could happen if you do not practice effective communication in this field.
