Autoimmunity. The immune system is a complex set of organs, cells, proteins and other substances that function to prevent infection. Primary immunodeficiency diseases are characterized by abnormalities in specific components of the immune system that lead to an increased susceptibility to infection.
How to Measure Ounces. Ounces are a measurement of mass or weight, and as such, you should use a scale when measuring ounces for a recipe, experiment, or similar procedure. In contrast, fluid ounces are a measurement of volume, so they are measured in a different manner. Note that there are also ways to estimate mass in ounces if precision is not necessary, and if required, you can easily convert a few other units of measurement into ounces.
The ounce (abbr. oz) is a widely-spread non-metric unit of mass or volume (fluid ounce), which is used in various systems and has several definitions. The US fluid ounce equals to about 29.6 milliliters, and the imperial fluid ounce equals to about 28.4 milliliters. The tablespoon (abbr. Tblspn, Tblsp, Tbsp, Tbs, Tb) â is a common unit of volume measurement used in the USA, Australia and some other countries. The US tablespoon equals to approximately 15 metric milliliters.
