In addition to gravity, muscular peristaltic waves, originating in the renal pelvis, squeeze urine down the ureters and squirt it into the bladder, the peristaltic movements consist of radially symmetrical contractions and in the relaxation of the muscles that propagate in a wave downwards in the muscular tube, in an antegrade manner, such movements are also found in the esophagus and stomach.

Question is incomplete, the complete question is as follows :
Clotting begins when a _________ occurs in a blood vessel wall. Almost immediately, _______ cling to the blood vessel wall and release _____________ which helps to decrease blood loss by constricting the vessel. __________ is also released by damaged cells in the area. This chemical substance causes ________to be converted to ____________. Once present, thrombin acts as an enzyme to atatch ___________molecules together to form long, threadlike strands of _________, which then traps ____________ flowing by in the blood.
Answer:
Clotting begins when a <u>BREAK</u> occurs in a blood vessel wall. Almost immediately, <u>PLATELETS</u> cling to the blood vessel wall and release <u>SEROTONIN</u>, which helps to decrease blood loss by constricting the vessel. <u>THROMBOPLASTIN</u> is also released by damaged cells in the area. This chemical substance causes <u>PROTHROMBIN</u> to be converted to <u>THROMBIN</u>. Once present, thrombin acts as an enzyme to attach <u>FIBRINOGEN</u> molecules together to form long, threadlike strands of <u>FIBRIN</u>, which then traps<u> ERYTHROCYTES </u>flowing by in the blood.
