2. Divide vehicle operation costs, $293.83 per month in our hypothetical scenario, by the distance you drive per month, 750 miles (1,207 km) in our example, to calculate the cost per mile. The cost per mile for this hypothetical driver and vehicle is 39.17 cents per mile or 24 cents per kilometer.
The digestive juices are a team of powerful enzymes produced by the mouth, stomach and small intestine that break down the three major types of nutrients into their constituent parts so that they become absorbable by the body.
Structure of the Small Intestine: explain. The small intestine is structurally modified to maximize absorption. About 1.8 L of intestinal juice is produced via osmosis and by the secretions from intestinal glands. This fluid is important for digestive and absorptive processes. The major stimulus for production of intestinal juice is distension of the intestinal mucosa by hypertonic or acidic chyme. The normal pH of intestinal juice is slightly alkaline (7.4-7.8) and is made up mainly of water but also contains some mucus and electrolytes (isotonic to the blood).
