Digestive System

The circulatory system, also called the cardiovascular system, is the heart and the network that brings blood to body tissue. It carries oxygen and nutrients to cells.

i think it's a monkey's

You see, the circulatory system is a whole network of blood cells being pumped throughout the entire body. The respiratory system has the main purpose of exhaling carbon dioxide, which can be deadly to the body, and inhaling oxygen to give your muscles the energy to move. This is only part of it. Without the circulatory system, there would be no way to circulate the blood throughout the body. Therefore they are related by working together to transport oxygen for each muscle and organ in the body.

Certain evolution-minded people think that it is the remnant of an organ that allowed our ancestors to digest cellulose, enabling them to eat greenery. However, there are several opposing schools of thought regarding this. Recent findings indicate that the appendix is not actually as useless as has been previously thought, and may play an important role in various physiological functions such as the human immune system.

Long ago when food was dirty, the appendix separated dirt from food. Kind of like a filter for the body. Now that our food is clean, it is no longer usable. Some times it may get infected. If that happens, (appendicitis) you must have surgery to get it out before it explodes.

Scientists today do not actually know what the actual function of the appendix even is - some say that it is a vestigial organ, others say that it is an important factor in the immune system, and others say that it can function as a storehouse for helpful bacteria during an illness which kills all the other intestinal bacteria. Because we do not know what the appendix's function really is, this question has no real answer.

the appendix has no use.

You don't need appendix. It is a vestigial structure that only might get in your way if it becomes inflamed.

However, recent research shows that it creates helpful bacteria.

The appendix has been shown in recent years to help produce certain enzymes which can ward off some disease.

Answer 2: Just because we don't know the reason for some feature in an organism does not mean that it doesn't have an important role to play. For example, so called vestigial organs were once thought to show that the human body and other organisms were poorly designed. The appendix and tonsils, for instance, were once thought to be vestigial organs and were removed. But then it was discovered that these organs play a role in the immune system, and they are no longer considered vestigial. (see 9/06 Awake article pg 12 An Interview With a Biochemist on Jehovah's Witness official website)

its cause so many idiots think that they have a well developed immune system and eat stupid stuff, or they are just plain idiots out traveling the world eating exotic foods and getting foreign stomach diseases.

Well, you eat stuff. Once you eat stuff, you get energy. After you eat stuff and receive energy, you excrete that stuff back out, minus the energy you took from it.

The lungs bring air into the air sacs, which are tightly wrapped with capillaries. The capillaries exchange oxygen for carbon dioxide, which the lungs expel.

Basic.

The tongue assists in manipulation of food once it enters the digestive tract. Of course, one's hands also assist in food manipulation.

The digestive tract that carries food includes the mouth, pharynx, esophagus, stomach, small intestine and large intestine. Other organs, such as the pancreas, are part of the digestive system, but don't carry the food.

The difference is mainly due to the complexity of carbohydrate digestion. Humans have a single stomach, where ruminants have a multichambered stomach to digest carbs more completely.

Show the body, and then show the food going down the body, but it really depeneds on whst type of project you are doing.

Answer Is Digestive!

Your stomach performs both mechanical and chemical digestion. The stomach is a muscular sac that physically squeezes food about three times per minute. It also secetes enzymes and acid that chemically digest food particles.

hi i just fooled you ha ha lol

peristalsis

My family has had there appendix bursting alot now so i can answer this question. If your appendix bursts you can barely stand up straight and you puke alot and if you dont get it fixed it will make you have an infection cus the appendix holds the bateria and stuff so it will become infected and you will get really sick and it could event to fatal death.

Herbivores have long digestive tracts because it takes a long time to absorb nutritents from the plant material which they eat. They also have a large caecum which helps, along with enzymes, breakdown the plant material and cellulose. Carnivores have shorter digestive tracts as they can obtain nutrients from the meat they consume more quickly. They have a realatively small caecum as their diet only consists of small amounts of plant material.

By peristalsis movement .
