The endoplasmic reticulum (ER) is a series of interconnected membranes or flattened sacs adjacent and connected to the nuclear membrane. The ER comes in two different morphological forms: smooth endoplasmic reticulum (sER) and rough endoplasmic reticulum (rER). The primary function of the sER is to serve as a platform for the synthesis of lipids (fats), carbohydrate (sugars) metabolism , and the detoxification of drugs and other toxins.

An ultrasound test (sonogram) is a painless exam that uses sound waves to check a pregnancy or to get images of body organs. An ultrasound can give your doctor almost the same information as an x-ray, but it doesnât expose you to harmful radiation. There are 3 types of ultrasound: pelvic, pregnancy, and abdominal. Each test takes about 1 hour.
