Hypocalcemia or low calcium level is most usually the cause of electrolyte disturbance after a thyroid surgery.
In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.

2. All cells arise from pre existing cells(Rudolf Virchow). Cell is the fundamental, structural and functional unit of all organisms(Schleiden and Schwann).
3. All cells have a cell membrane.
All cells have chromosomes present.
All cells have cytoplasm.
4.Eukaryotic cells contain a nuclear membrane but Prokaryotic cells have only pseudo nucleus
Eukaryotic cells contain membrane bound organelles but prokaryotic cells don't.
