Glands in the cervix and the walls of the vagina normally produce a clear mucus. This is very common among women of childbearing age. 1  These secretions may turn white or yellow when exposed to the air. 2  The amount of mucus produced varies during the menstrual cycle as hormone levels in the body change.
Similarly, the time that it will take for your dog to digest his food also depends upon what type of food he eats. Generally speaking, raw food and canned food will move through his system faster than dry food; it typically takes between 4 and 6 hours for a dog to process a meal's worth of canned food. On the other hand, it may take as many as 8 to 10 hours for the same dog to process dry food completely. Other Factors
Studies have shown that the entire process takes about an average of 50 hours for healthy people, but can vary between 24 and 72, based on a number of factors. After chewing food and swallowing it, it passes through the stomach and small intestine over a period of 4 to 7 hours. The time passing through the large intestine is much longer, averaging about 40 hours. For men the average time to digest food is shorter overall than it is for women. Having a digestive condition that affects transit time (the time it takes for food to pass through the digestive system) can shorten or extend the time.
