pregnancy 2nd trimester

2nd Trimester

Pregnancy in humans is divided into three trimesters from the last menstrual period (LMP). The second trimester of pregnancy lasts for 13 to 27 weeks after conception. During this period, we observe notable changes in female bodies with the increase in abdomen size due to the rapid uterus growth. Moreover, as the musculoskeletal system of the unborn develops, between second trimester weeks 16 to 20 of pregnancy, the mother can experience baby movements. It is considered the golden phase of pregnancy, as the initial symptoms of pregnancy diminish and an increase in energy levels are observed. Due to the risk of teratogenicity and fetal complication, there is a limited scope of research in pregnant women.

By definition, the period between the 14th week of pregnancy and the 27th week is called the second trimester. By the 27th week of pregnancy, the five-to-six-centimetre foetus becomes a baby. Furthermore, at the end of the second trimester, the baby grows 35 centimetres tall and weighs 900 grams.
The end of the first trimester marks the complete development of the vital organs of the unborn. Also, during this stage, blood formation begins, the brain and nervous system develop, and the foetus also starts to move. In the 2nd trimester, the skeleton hardens, the genitals can be distinguished, and facial expressions of the baby become visible. Besides, hearing, sleeping, and waking phases also develop in the baby during this course. At the end of the second trimester, the unborn start to open their eyes.
Major unpleasant signs of pregnancy, such as nausea, circulation problems or tiredness, usually disappear during the early 2nd semester of pregnancy. However, a few issues that occur in the second trimester are Calf cramps, constipation, heartburn, body pains due to the stretching of the maternal ligaments, forgetfulness and headaches.
The circulation of mother and child are connected via the umbilical cord. From the 12th week of pregnancy, the nutrients are supplied to the developing fetus from maternal circulation through the placenta.
These are the serum and plasma samples isolated from the consented pregnant donors in 2nd trimester of pregnancy. The samples are indented for drug and diagnostic research and developments, well screened for pregnancy hormones like beta-HCG, and stored at <-18 °C at our supplier's biobank. Central BioHub also provides patient information such as the donor's, the week of pregnancy, medical history, and multiple pregnancy reports to substantiate the research validity.
