Invertebrate digestive system
It has decreased my bloating and has even helped my digestion, I love it! Please try again later. When our family studied the Digestive System again more recently, we spent quite a bit of time learning about the small intestine; liver, gall bladder and pancreas; and the large intestine. Research shows that broad spectrum enzymes can help breakdown lactose, proteins, carbohydrates, fibers and fats to help improve digestion. Some of the topics covered in this packet include an overview of the circulatory system, the heart, blood vessels arteries, veins, capillaries , blood flow through the heart, blood transport through the body, blood composition red and white blood cells, platelets , blood types, cholesterol, and diseases of the circulatory system.

Your Digestive System

It's time well spent because, at the end of the journey, the nutrients from your pizza, orange, and milk can pass from the intestine into the blood. Once in the blood, your body is closer to benefiting from the complex carbohydrates in the pizza crust, the vitamin C in your orange, the protein in the chicken, and the calcium in your milk. Next stop for these nutrients: And the leftover waste — parts of the food that your body can't use — goes on to the large intestine.

The nutrient-rich blood comes directly to the liver for processing. The liver filters out harmful substances or wastes, turning some of the waste into more bile.

The liver even helps figure out how many nutrients will go to the rest of the body, and how many will stay behind in storage. For example, the liver stores certain vitamins and a type of sugar your body uses for energy. At 3 or 4 inches around about 7 to 10 centimeters , the large intestine is fatter than the small intestine and it's almost the last stop on the digestive tract.

Like the small intestine, it is packed into the body, and would measure 5 feet about 1. The large intestine has a tiny tube with a closed end coming off it called the appendix say: It's part of the digestive tract, but it doesn't seem to do anything, though it can cause big problems because it sometimes gets infected and needs to be removed. Like we mentioned, after most of the nutrients are removed from the food mixture there is waste left over — stuff your body can't use.

This stuff needs to be passed out of the body. Can you guess where it ends up? Well, here's a hint: It goes out with a flush. Before it goes, it passes through the part of the large intestine called the colon say: CO-lun , which is where the body gets its last chance to absorb the water and some minerals into the blood.

As the water leaves the waste product, what's left gets harder and harder as it keeps moving along, until it becomes a solid.

Yep, it's poop also called stool or a bowel movement. The large intestine pushes the poop into the rectum say: REK-tum , the very last stop on the digestive tract.

The solid waste stays here until you are ready to go to the bathroom. When you go to the bathroom, you are getting rid of this solid waste by pushing it through the anus say: There's the flush we were talking about! You can help your digestive system by drinking water and eating a healthy diet that includes foods rich in fiber.

High-fiber foods, like fruits, vegetables, and whole grains, make it easier for poop to pass through your system. The digestive system is a pretty important part of your body. Without it, you couldn't get the nutrients you need to grow properly and stay healthy. And next time you sit down to lunch, you'll know where your food goes — from start to finish! For specific medical advice, diagnoses, and treatment, consult your doctor. More on this topic for: Kids Are Your Bowels Moving?

The roof of the mouth is concave and is formed by the hard and soft palate. The hard palate is formed by the horizontal portions of the two palatine bones and the palatine portions of the maxillae, or upper jaws.

The hard palate is covered by a thick, somewhat pale mucous membrane that is continuous with that of the gums and is bound to the upper jaw and palate bones by firm fibrous tissue. The soft palate is continuous with the hard palate in front. Posteriorly it is continuous with the mucous membrane covering the floor of the nasal cavity. The soft palate is composed of a strong, thin, fibrous sheet, the palatine aponeurosis, and the glossopalatine and pharyngopalatine muscles.

A small projection called the uvula hangs free from the posterior of the soft palate. The floor of the mouth can be seen only when the tongue is raised. In the midline is a prominent, elevated fold of mucous membrane frenulum linguae that binds each lip to the gums, and on each side of this is a slight fold called a sublingual papilla , from which the ducts of the submandibular salivary glands open.

Running outward and backward from each sublingual papilla is a ridge the plica sublingualis that marks the upper edge of the sublingual under the tongue salivary gland and onto which most of the ducts of that gland open.

The gums consist of mucous membranes connected by thick fibrous tissue to the membrane surrounding the bones of the jaw. The gum membrane rises to form a collar around the base of the crown exposed portion of each tooth.

Rich in blood vessels, the gum tissues receive branches from the alveolar arteries; these vessels, called alveolar because of their relationship to the alveoli dentales, or tooth sockets, also supply the teeth and the spongy bone of the upper and lower jaws, in which the teeth are lodged.
