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.
A cell junction (or intercellular bridge) is a type of structure that exists within the tissue of some multicellular organisms, such as animals. Cell junctions consist of multiprotein complexes that provide contact between neighbouring cells or between a cell and the extracellular matrix. They also build up the paracellular barrier of epithelia and control the paracellular transport. Cell junctions are especially abundant in epithelial tissues. Cell junctions are especially important in enabling communication between neighboring cells via specialized proteins called communicating junctions. Cell junctions are also important in reducing stress placed upon cells.
