Intravascular pressure and spontaneous contraction of the lymphatics

  • R. S. Orlov
  • T. A. Lobacheva


Relations between spontaneous contractile activity and the level of the intravascular pressure were studied in isolated segments of lymphatics. Spontaneous contractions arise when the pressure is of the order of 0.5–1.5 cm water. With an increase in pressure up to 5 cm water the frequency and amplitude of the contractions increase, but when the pressure is 10 cm water they decrease. The indices of the spontaneous rhythm of the lymphatics change not only with absolute values of the intravascular pressure, but also with the rate of their change.
