ascites is one of the late features of
Ascites In the developed world, the most common cause is liver cirrhosis.[3] Other causes include cancer, heart failure, tuberculosis, pancreatitis, and blockage of the hepatic vein.[3] In cirrhosis, the underlying mechanism involves high blood pressure in the portal system and dysfunction of blood vessels.[3] Diagnosis is typically based on a examination together with ultrasound or a CT scan.[2] Testing the fluid can help in determining the underlying cause.[2]
Paleozoic The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Fish, arthropods, amphibians, anapsids, synapsids, euryapsids, and diapsids all evolved during the Paleozoic. Life began in the ocean but eventually transitioned onto land, and by the late Paleozoic, it was dominated by various forms of organisms. Great forests of primitive plants covered the continents, many of which formed the coal beds of Europe and eastern North America. Towards the end of the era, large, sophisticated diapsids and synapsids were dominant and the first modern plants (conifers) appeared.
