Differences between a birds respiratory system and a humans?

Answer 1

Both chicken's and humans have similarities in the digestive system such as a large intestine and esophagus. The difference is that chickens have a proventriculas and a gizzard, while humans have a stomach and mouth.

Answer 2

A bird's digetive system is different because a bird has a gizzard unlike a human, in the gizzard are rocks and pebble to help make the food smaller ,because the bird may not be able to chew it's food up completely.

Answer 3

Birds have a more efficient respiratory system, with air flowing in one direction through their lungs, allowing for greater oxygen exchange. They also have air sacs that help keep their respiratory system efficient during flight. In contrast, humans have a two-way respiratory system with air flowing in and out of the lungs.

Answer 4

The difference between the sheeps disgestive system and the humans digestive system is that the sheep is a ruminant and has four stomachs and the human is a monogastric and only has one stomach. I hope this answered your question.

Answer 5

There are no villi in the small intestine of a frog. The frog's digestive system begins with the mouth. Frogs have teeth along their upper jaw called the maxillary teeth, which are used to grind food before swallowing. These teeth are very weak, and cannot be used to catch or harm agile prey. Instead, the frog uses its sticky tongue to catch food (such as flies or other insects). The food then moves through the esophagus into the stomach. The food then proceeds to the small intestine (duodenum and ileum) where most digestion occurs. Frogs carry pancreatic juice from the pancreas, and bile (produced by the liver) through the gallbladder from the liver to the small intestine, where the fluids digest the food and extract the nutrients. When the food passes into the large intestine, the water is reabsorbed and wastes are divided into liquids and solids. Liquid wastes go to the urinary bladder, while solids are routed to the cloaca. All wastes exit the body through the cloaca and the cloacal vent.

The human digestive tract is the system of organs within multicellular animals that takes in food, digests it to extract energy and nutrients, and expels the remaining waste. The major functions of the GI tract are ingestion, digestion, absorption, and defecation.

The GI tract differs substantially from animal to animal. Some animals have multi-chambered stomachs, while some animals' stomachs contain a single chamber. In a normal human adult male, the GI tract is approximately 6.5 meters (20 feet) long and consists of the upper and lower GI tracts. The tract may also be divided into foregut, midgut, and hindgut, reflecting the embryological origin of each segment of the tract.
