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.
A pyroclastic flow is a sudden, quick, and very hot movement of gases, dust, ash and/or rock mixtures due to volcanic eruptions that move across the ground at high speeds. Tweet. About The Author Matt Slick is the President and Founder of the Christian Apologetics and Research Ministry.
