The First Two Months of Pregnancy
Each of us began life being a single cell. That phase of life lasted an incredibly short time, however. Right after conception, the only fertilized cell burst into action by dividing and creating new cells. Once of birth, one cell had multiplied into trillions of cells. Not each cell became an exact replica from the other. Although each cell offers the same genetic material, teams of cells developed specialized functions in the process. This specialization allowed cells in order to create specific tissues and organs that might perform particular functions. The brain are able to remember and reason, and our bodies can digest food, eliminate waste, combat infection, renew bone, and perform a huge number of other functions because groups of cells develop differently from other groups.
Its not all tissues and organs were formed by teams of specialized cells as well. There was a preprogrammed time for development for each and every tissue and organ within our bodies. Our spinal cords, which resulted in our brains, were formed within twenty-three days after conception. By thirty day period after conception, in everyone a cluster of cells had formed a heart that beat weakly. Arms, legs, fingers, and toes had also taken shape at that same moment. Within two more weeks, teams of cells had formed basic the different parts of the liver, pancreas, stomach, ears, eyes, and lungs. These miraculous accomplishments occurred prior to cluster of cells, known as the embryo, weighed 5 grams, or weight of an nickel! Each tissue and organ had to develop on schedule concerning was no second chance. Development is over a very strict timetable.
In order for tissues and organs to create and function normally, all building materials has to be present at that time tissues and organs are developed to develop. If sufficient oxygen, water, glucose, vitamins, or minerals are certainly not available at occasions, development falters. Ill-timed exposures to medications (some anticonvulsants, antibiotics, and chemotherapeutic agents, for example), toxic agents inside environment (for example, DDT, PCBs, mercury, lead), radiation, infectious agents, alcohol, and high levels of certain nutrients might also interrupt normal fetal development. Experience of these insults during tissue and organ formation can result in miscarriage, malformations, or impaired both mental and physical development of the fetus. The period of time in pregnancy when these exposures are most hazardous on the fetus is between implantation (approximately five days after conception) and 8 weeks after conception.
Tissues and organs grow in size and weight when they have formed. This pattern of growth signifies that the major gains in fetal weight occur later during pregnancy. Once tissues and organs are formed, they may be no longer prone to insults that cause malformations. Insults occurring later in pregnancy, however, like exposure to toxic substances and poor diets, may lead to normally formed but undersized organs that won't function optimally.
With there being so many factors that will affect tissue and organ development, it is almost always difficult to decide if a specific condition was to blame for a problem occurring in the individual newborn. Not every pregnancy is affected, or affected inside the same ways, by contact with harmful substances. Moreover, many of the factors behind abnormal fetal development aren't known. Looking to isolate just one factor that could have disrupted fetal development or growth is usually an exercise in futility for any individual pregnancy.
Inspite of the susceptibility with the fetus throughout the first few months of pregnancy, most babies are born healthy and normal. Chances are excellent, however, that mothers intend to do the most and finest they are able to for their babies while pregnant. The shared goal is surely an above-average baby, one that is as healthy and in addition developed as you can. The outcome is not guaranteed, nonetheless it can be helped along by ''growing the child in the right oven."
