Lung ventilation contributes to vertical lymph movement in anurans.
Anurans (frogs and toads) generate lymphatic fluid at 10 times the rate in mammals, largely as a consequence of their very 'leaky' vasculature and high interstitial compliance. Lymph is ultimately pumped into the venous system by paired, dorsally located lymph hearts. At present, it is unclear how lymphatic fluid that accumulates in central body subcutaneous lymph sacs is moved to the anterior ...
متن کاملUnique role of skeletal muscle contraction in vertical lymph movement in anurans.
Electromyographic (EMG) activity of skeletal muscles that either insert on the skin or are associated with the margins of subcutaneous lymph sacs was monitored for two species of anurans, Chaunus marinus and Lithobates catesbeiana (formerly Bufo marinus and Rana catesbeiana). Our hypothesis was that contraction of these muscles varies the volume, and hence pressure, within these lymph sacs, and...
متن کاملEvolution of forelimb movement patterns for prey manipulation in anurans.
Unlike other amphibians, frogs often use their forelimbs to capture and transport prey. In the present study, high-speed videography was used to observe forelimb use during feeding in a diverse group of anurans in order to determine the evolution of forelimb movement patterns among anuran taxa. Data were gathered from 488 individuals representing 104 species, 55 genera, and 16 families. Five di...
متن کاملIndependent Lung Ventilation and One Lung Ventilation
The application of the independent lung ventilation (ILV) in adults has been described by Carlon and co-workers in 1978 and subsequently by other investigators. In 1983 Hedenstierna and coworkers using a bilumen tube suitable for prolonged intubation, and two Servo Ventilator 900 B (Siemens) adapted for synchronization, treated a wide range of clinical conditions. Following this experience, the...
متن کاملOther approaches to open-lung ventilation: airway pressure release ventilation.
OBJECTIVE To review the use of airway pressure release ventilation (APRV) in the treatment of acute lung injury/acute respiratory distress syndrome. DATA SOURCE Published animal studies, human studies, and review articles of APRV. DATA SUMMARY APRV has been successfully used in neonatal, pediatric, and adult forms of respiratory failure. Experimental and clinical use of APRV has been shown ...
