What animal has a two way digestive system?

Most animals above the level of cnidarians and flatworms have a complete digestive tract; i.e., a tube with two openings—a mouth and an anus.

Which animal is known to take up to a mouth to digest food?

Earthworms are an example of an animal with an alimentary canal. Once the food is ingested through the mouth, it passes through the esophagus and is stored in an organ called the crop; then it passes into the gizzard where it is churned and digested.

How do reptiles remove waste?

In snakes and lizards, these wastes are eliminated from the cloaca together with wastes from the digestive system. Prior to the evolution of the metanephric kidney, the products of the male gonad, the testis, traveled through the same duct with the nitrogenous wastes from the kidney.

What animal has a complete digestive system?

Since animals with complete digestive systems can get the most nutrients out of their food and keep eating, larger, more complex animals evolved. All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects have complete digestive systems.

Which animal has best digestive system?

After a meal the heart directs deoxygenated blood, rich in acidic carbon dioxide, to the stomach. The blood stimulates the production of the most acidic gastric juices known in nature. This remarkable system means crocodiles can secrete stomach acid 10 times faster than any other animal.

What is the part of digestive system?

The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

Do fish have throats?

Most fishes have only short gill rakers that help keep food particles from escaping out the mouth cavity into the gill chamber. Once reaching the throat, food enters a short, often greatly distensible esophagus, a simple tube with a muscular wall leading into a stomach.

What is digestion in fish?

Fish ingest food through the mouth and break it down in the esophagus. In the stomach, food is further digested and, in many fish, processed in finger-shaped pouches called pyloric caeca, which secrete digestive enzymes and absorb nutrients. ... The intestine completes the process of digestion and nutrient absorption.

Which animal has both external and internal digestion?

Most invertebrates use some form of extracellular digestion to break down their food. Flatworms and cnidarians, however, can use both types of digestion to break down their food.

How do crocodiles excrete waste?

Water is lost from the body during breathing, and both salts and water are lost in the urine and faeces, through the skin, and via salt-excreting glands on the tongue, though these are only present in crocodiles and gharials.

What animals excrete ammonia?

Typically, aquatic anurans excrete ammonia (ammonotelic), because conserving water is not important. Urea-excreting animals (ureotelic), like toads, will have some contact with water. They produce dilute urine when they are in freshwater and typically do not urinate on land (thus, their plasma urea elevates).

How does lizard excrete?

All reptiles excrete uric acid and thus do not need great amounts of liquid to rid themselves of nitrogenous wastes. All insectivorous lizards take in a large amount of water in the prey that they consume, and herbivorous lizards have salt glands for the active excretion of mineral salts.

Which of the following animals has an incomplete digestive system?

-Primitive animals including sponges, roundworms, coelenterates, ctenophores, etc. have an incomplete digestive tract.

What are dioecious animals?

Dioecious animals are those animals in which male and female reproductive organs are present in separate individuals. For example, Cnidarians like Aurelia are dioecious.

Do fish have complete digestive systems?

The structural components of a fish's digestive system include the mouth, teeth and gill rakers, esophagus, stomach, pylorus, pyloric caeca, pancreatic tissue (exocrine and endocrine), liver, gall bladder, intestine and anus. Not all components are present in all fish [ha!]
