Pulmonary specialists work closely with other doctors and nurses as a part of a medical care team. Pulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart again. A pulmonary specialist treats patients who have problems with their lungs or respiratory systems. Becoming a pulmonary specialist requires a major commitment to education. A pulmonary specialist must have a comforting bedside manner.
Cell plate is the structure found inside the dividing cells of terrestrial plants and some algae. It develops in the middle plane of the cell separating two daughter cells during cell division. In animal cells, cytokinesis is carried out by the formation of cleavage furrow but in plant cells it is by the formation of cell plate. Compare: cleavage furrow. See also: cell division, mitosis, telophase.
Cell Membrane Function. The cell membrane (plasma membrane) is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape.
