Also, in releasing the Valsalva maneuver blood pressure falls, this, coupled with standing up quickly to leave the toilet, during defecation, the external sphincter muscles relax. These defects, which affect the structure of the heart, cause oxygen-poor blood to flow out of the heart and to the rest of the body. Additional reparative or reconstructive surgery may be done on patients as required by their particular cardiac anatomy.

A series of nuclear divisions will occur without cytokinesis in the zygote to form a cell known as a syncytium. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment.
