Encyclopedia of Fish Physiology: Some fish species create noise by engaging specialized muscles that contract and cause swimbladder vibrations. Journal of Anatomy Most fish are ectothermic "cold-blooded" , allowing their body temperatures to vary as ambient temperatures change, though some of the large active swimmers like white shark and tuna can hold a higher core temperature. This surface layer is typically quite thin, but dramatically reduces speed of the airflow towards the rear of the wing. In addition, bristles around the mouth may help protect the eyes from food items a bird is trying to capture Conover and Miller

Are our senses really so strictly divided? Try putting your toothpick of lemon juice where sweet should be, or your sugar where salty should be! Moving along through the digestive process, our mouth does a lot more than just taste your food!
When you take a bite of something like a crunchy apple your mouth produces saliva , a liquid containing enzymes that softens and dissolves your food.
Your teeth mash together, chomping and breaking things down smaller pieces. Your tongue pushes the pieces of food together into a lump of chewed food called a bolus. When you swallow the bolus, your esophagus muscles swing into action to start pushing your food down toward your stomach.
Once your food is pushed into your stomach, the real digestive action begins! While it is called the small intestine because of its diameter just about 1 inch , this organ is actually quite large, ranging from 10 ft to 22 ft in length!
It is here where the vast majority of the nutrients are absorbed from your food! Once your food has traveled through your small intestine, it makes its way through the large intestine! The large intestine is only 5 feet in length, but has a diameter of about 2.
Your large intestine will also absorb most of the water from the slop, leaving behind a semi-solid mass of waste material. From here, it will be stored in the rectum until it can be eliminated from your body as fecal waste poop! Set this aside for later use. Take your peanut butter sandwich and break it up into tiny pieces. Put the pieces into the sandwich bag and add your water. This will act as the saliva, further breaking down your food. Add the acid into your bag, simulating the hydrochloric stomach acids that work to break down your food.
Continue mashing your food, pretending that your hands are acting as stomach muscles! Take your nylon tube and hold it over your shallow pan. Pour your chyme into the nylon. Start squeezing the chyme through the nylon. This would be the nutrient rich material that is absorbed through the small intestine! If you want to get really detailed, you can roll it into a nice shape, and examine your handiwork. You should have a nice round pile of…. Now, there is a much more palatable way of appreciating our digestive system.
One of our favorite projects of all time, was when I surprised my daughter and niece with making our very own digestive system anatomy cake! It was really easy, and really fun! Cake Mix and the supplies for baking!
Take your kids to the dollar store and pick out a bunch of candy! Have them make a list before you go, detailing what kind of candy they might use for each organ. We ended up using the following candies: We used a simple box cake. I let the kids bake the cake themselves, which gave an added bonus lesson of math and measurements in the kitchen!
Tape that down as well. Fill your bag with icing and trace the organ onto the plastic wrap! Once you have it all drawn out and filled in, carefully move the plastic wrap onto a plate. Put this plate in the freezer for approximately 15 minutes.
Repeat the process for any other organs you need to draw on. Alternatively, you could draw on the organs with toothpicks or wooden skewers. This will put the foundation of icing on your cake so you can then lay the details of your digestive system. Now let the kids make their model of the digestive system! What are they going to use for teeth? How should they place the esophagus? Where should they put everything so that it fits in its proper place? Take your organs out of the freezer and lay them icing side down on your cake.
Have the kids make their own labels and tape them to toothpicks. Then have them stick the labels where they go. Stand back and admire your kitchen anatomy skills, and take a lot of pictures! Here is an adorable skeletal model made with veggies! Use this as inspiration and carve your organs out of vegetables!
We had a fantastic time learning about the digestive system! The science projects we did really added a lot to our learning experience and made it so that the kids were able to recall each function of the various organs, long after we were finished learning about them!
Below are some of the resources that we found to be useful along our learning explorations. This prompted a four year journey to develop the most advanced, all-in-one, full-spectrum, digestive and systemic enzyme formula that was vegetarian and vegan friendly -- no animal sources. One challenge was including glucose oxidase , an enzyme that converts sugar into hydrogen peroxide bees secrete it into honey for indefinite preservation.
In fact, Global Healing Center is the first company in the world to offer this enzyme. We produce the best products possible and we're proud to say that VeganZyme, the most complete, full-spectrum enzyme formula in the world. Promotes Digestion Enzymes are necessary for digestion and nutrient absorption and, unfortunately, your body produces less as you age.
VeganZyme fills the gaps to enhance digestion and increase the nutritional value of food. May also help reduce bloating, gas or indigestion from food sensitivities.
Systemic enzymes are to your body what oil is to your car's engine -- lubrication that keeps the machine moving smoothly. Think of them as power-ups for your body's natural processes that promote functional balance. VeganZyme is the most complete digestive and systemic enzyme blend available anywhere, and it's totally vegan-friendly! VeganZyme is formulated by Dr. Edward Group and produced here in the United States.
Completely void of toxic additives, VeganZyme is the most premium enzyme supplement available. No other product can compare. We are sure you will see and feel the health benefiting results of enzyme supplementation with VeganZyme. Why do I need enzymes?
Enzymes are responsible for constructing, synthesizing, carrying, dispensing, delivering, and eliminating the ingredients and chemicals our body uses.
Digestive enzymes break down food to release nutrients for energy production, cell growth, and repair. Systemic enzymes support the body's processes. Does food contain enzymes? Raw, live foods contain enzymes; cooked and processed foods are void of enzymes. A digestive enzyme supplement enhances digestion to get the full nutritional value of food. As active protein molecules, enzymes do not accumulate in the body. It sets standards for ingredients. In the case of enzymes, FCC is a standard assay used to accurately determine the activity of enzymes.
Take 2 capsules twice daily. For digestive support, take enzymes at mealtime with first bite of food. For systemic support, take at least 30 minutes before or 2 hours after a meal with a full glass of purified water.
Keep out of reach of children. Consult your healthcare provider if pregnant, nursing, taking blood thinners or for any additional concerns. Digestive enzymes, such as amylase, protease and lipase break down foods into smaller components that are more easily absorbed. Enzymes are secreted throughout the digestive tract. Beginning in the mouth, starches and fats break down as they are chewed and mixed with saliva, which contains amylase ptyalin and lingual lipase.
Once swallowed, it travels to the stomach where protease pepsin begins to break down protein into smaller peptides and amino acids. This mixture is transferred to the first part of the small intestine.
A number of proteases trypsinogen and chymotrypsinogen, for example are released with pancreatic lipase and amylase from the pancreas in their inactive forms into the small intestine where they are activated. Systemic enzymes help other processes in the body and control swelling, reduce fibrin a blood-clotting factor levels, thin mucus, support cardiovascular and joint health, and more. Systemic enzymes have been used in many types of therapy and it has been suggested that enzyme supplementation is probably beneficial for most people.
This codex standardizes the activity units of enzymes for easy comparison. Historically, enzymes have been measured using different units at the discretion of the manufacturer or scientist measuring activity.
There is now an attempt within the nutraceutical industry to use standardized measurements so that materials are comparable from product to product and between suppliers. Compounding this problem is the fact that there are often many grades of raw materials available from raw material suppliers, meaning that you must multiply the activity per gram of the particular enzyme by the weight of the amount that is used per serving in order to calculate the activity of the amount that you are ingesting.
This can be listed in different ways on supplement labels, so it is important to make sure you understand what you're getting. The VeganZyme label indicates the activity per serving for ease of use. If you are trying to compare a number of different products that use different units of activity, it may not be possible since they may measure completely different actions for which there is no equivalency.
