ood to the heart by ________. squeezing blood from the rhythmic contraction of the diaphragm muscle decreasing the pressure gradient between abdominal and thoracic veins during expiration raising the pressure gradient between abdominal and thoracic veins during inspiration decreasing the pressure gradient between abdominal and thoracic veins during inspiration raising the pressure gradient between abdominal and thoracic veins during expiration
The respiratory pump facilitates the return of blood to the heart by raising the pressure gradient between abdormal and thoracic veins during inspiration. Respiratory pump are those abdormal and thoracic structures that contribute to the expansion and contraction of the lungs. Movement of the chest and abdomen alters central pressures during inspiration and expiration.
