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.
The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.he cell employs a number of transport mechanisms that involve biological membranes: 1. Passive osmosis and diffusion: Some substances (small molecules, ions) such as carbon dioxide (CO 2) and oxygen (O 2), can move across the plasma membrane by diffusion, which is a passive transport process.
