Rotation is the act of raising the nose of an aircraft (by pulling back slightly on the control yoke or stick) during the take-off roll, so that it leaves the runway. Rotation allows for a precise, positive departure from the runway.
Crenation is the loss of water from an animal cell due to osmosis. Lysis is the rupture of the cell wall due to too much water moving into an animal cell due to osmosis. Both â¦crenation and lysis have drastic effects on the animal cell.
Any device inserted into the vascular system increases the risk of thrombus formation, either in the vessel or in the catheter. The 3 primary causes of thrombus formation in a vessel are known as the Triad of Virchow. The first cause is alteration of the vein wall by injury, irritation, or disease process. Vein irritation can occur during PICC insertion or when the vessel is too small to accommodate the diameter of the PICC. A PICC that is too large will abrade the intima of the vein into which it has been inserted.
