For example, vacuoles in stomata cells contain large numbers of potassium ions, which can be pumped in or out to open or close the stomata. Animal Cells In animal cells, vacuoles serve more subordinate roles, such as assisting in endo- and exocytosis or basic storage of food and waste. Central Vacuole The central vacuole is found only in plant cells. It is filled with water and is pressurised, like a balloon. This forces all the other organelles within the cell out toward the cell wall. This pressure is called turgor pressure and is what gives plants their crisp and firm structure.
A nasogastric (NG) tube is a long, narrow feeding tube that goes through your nose and down into your stomach. The NG tube is soft and bendable.

A coronary angiogram is a procedure that uses X-ray imaging to see your heart's blood vessels. The test is generally done to see if there's a restriction in blood flow going to the heart. Coronary angiograms are part of a general group of procedures known as heart (cardiac) catheterizations.
