A blood alcohol concentration (BAC) or blood alcohol level (BAL) reflects the amount of alcohol in the body. Food, type and quantity of beverage, weight, sex, and rate of elimination determine the BAC after the consumption of alcohol.
The process of oxygen transfer in the gills of a fish is a good example of the benefits of countercurrent exchange. As oxygen poor blood meets an opposed flow of oxygen rich water, the oxygen begins to diffuse out of the water and into the blood stream.
It is the northward flow component of the S. Atlantic subpolar gyre. The Malvinas current transports cold water along the coast of S. America and this water mixes with warmer waters of the Brazil current in an region known as the Brazil-Malvinas confluence.Click here for example plots of seasonal averages.he along-shelf flow of the Malvinas Current is highly variable from year to year, and it does not appear to have an annual or even a semi-annual cycle. However, there is a suggestion of significant energy at periods of about 135 days (Vivier and Provost 1999a, 1999b).
