Question
1. college students have been known to consume an alcoholic beverages or two after they've completed their studies for the evening. Some even have more than they should, and wake up the next morning with a terrible condition known as a hangover. one of the symptoms of a hangover is the cottony dry mouth condition, associated with dehydration.
a. describe the concentration of solutes outside of the cells relative to the interior cytoplasm, and the effects of those conditions.
b. how can students completely avoid or at least counteract the dry mouth condition?
2. the capillaries of our circulatory system have been described as being leaky. what exactly is leaking out? how is that possible? what happens to the stuff that's leaking out of the circulatory system-where does it go? here, you should describe that "parallel plumbing or drainage system in the body as well as functions it serves. .
please answer with scientific thinking
Explanation / Answer
1.
a. Being a potent diuretic, alcohol dehydrates the body, along with loss of a large quantiry of potassium, sodium and other minerals. In chronic alcoholics, the extra cellular solute concentration decreases due to the body's attempt to retain water. Extracellular water volume increases, which leads to an inbalance between the intra cellular and extra cellular compartments.
b. Consumption of large quantities of water prevents dry mouth condition

The capillary lining is composed of a single layer of endothelial cells whose edges have a flip-flop overlapping. These overlapped sites are generally cemented by the cell cementing substance. With every heat beat, our blood vessels receive more volume of blood than thay can actually accommodate. This mechanism ensures maintenance of proper blood pressure.
At any given instance, at a particular anatomical region, only 5-10% of blood vessels are open and the other vessels remain closed. Local Oxygen and carbondioxide tension, acidity, regulate the opening and closing of blood vessels. Capillary blood vessels have a precapillary sphincter that responds to the said conditions. In addition, passive dialation of blood vessels also can occur when there is a large volume of blood flowing.
With each heart beat, due to the high capillary blood pressure, a small amount of cell free blood plasma leaks out into surrounding tissue spaces. The leaked plasma is collected and pumped back to the heart as Lymph, through lymphatic circulation. the lymph drains into the blood stream at right and left subclavian veins.
Lymph circulation serves immune functions of protecting the body from foreign invaders. The lymph that is carreid back into the blood is thoroughly filtered at various levels, in the lymph nodes.
Lymph flow is unidirectional, it has no pumping organ, and its upward movements are facilitated by muscular actions and movements of the body.
