How is food moved through the esophagus? The esophagus takes the food from the mouth to the stomach. Food moves through the esophagus by peristalsis, which is muscle contractions the pushes the food downward. At the … end of the esophagus is the lower esophageal sphincter (LES), which prevents food from re-entering the esophagus after it's reached the stomach.

- The esophagus is like a muscular tube about 25 cm long between the throat and the stomach. It passes behind the trachea and heart, and then goes through the diaphragm and into the stomach. Muscles in the sides of the esophagus squeeze and relax during swallowing, forcing food down toward the stomach. The esophagus is a muscular tube that connects the throat, or pharynx, to the stomach. It's the long tube that connects the mouth to the stomach to allow the food to pass through.

Fish anatomy 1 In many fish, the pectoral fins aid in walking, especially in the lobe-like fins of some anglerfish and in the mudskipper. 2  Certain rays of the pectoral fins may be adapted into finger-like projections, such as in sea robins and flying gurnards.

- Esophagus. The esophagus conveys food from the pharynx to the stomach by means of peristaltic waves which begin as a result of the swallowing reflex. The inner wall of the esophagus is lined with stratified squamous epithelium.It shows up as large purple on your slide. Notice that the cells at the base of this epithelial layer are cuboidal. This is the region where mitosis occurs. As new cells are produced they are pushed nearer the surface and become flattened.sophagus.

esophageal ESOPHAGUS: (as seen through an endoscope) The muscular tube, about 10 to 12 in (25 to 30 cm) long, that carries swallowed foods and liquids from the pharynx to the stomach. In the upper third of the esophagus, the muscle is striated; in the middle third, striated and smooth; and in the lower third, entirely smooth. Peristalsis is regulated by the autonomic nervous system.

Esophagus At the superior end of the esophagus is the upper esophageal sphincter that keeps the esophagus closed where it meets the pharynx. The upper esophageal sphincter opens only during the process of swallowing to permit food to pass into the esophagus.

Food takes two to three seconds to move through the esophagus when a series of …muscles contract and relax one after the other, squeezing food downward toward the stomach.

- The pharynx or throat follows from the oral cavity, and is continuous to the esophagus. In fishes, both food and air enters the mouth and empty into the pharynx and the nasal pits are not continuous with the mouth.

- Megaesophagus, also known as ME, is a condition in humans, cats, dogs and horses where peristalsis fails to occur properly and the esophagus is enlarged. Normally, when the animal's esophagus is functioning properly, it acts as a muscle and pushes the food down the esophagus into the stomach. However, when an animal has megaesophagus, the esophagus stays enlarged and does not push the food down to the stomach. Therefore, the food fails to enter the stomach and often stays in the esophagus, and is eventually regurgitated, or enters the lungs through breathing, or decays in the esophagus. In human pathology a condition known as achalasia may predispose a person to slowly develop megaesophagus.

Esophagus The esophagus (American English) or oesophagus (British English), commonly known as the foodpipe or gullet, is an organ in vertebrates which consists of a fibromuscular tube through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.he upper esophagus lies at the back of the mediastinum behind the trachea, and in front of the erector spinae muscles and the vertebral column. The lower esophagus lies behind the heart and curves in front of thoracic aorta.

Fish anatomy The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does.he skeleton of the fish is either made of cartilage (cartilaginous fishes) or bones (bony fishes). The main features of the fish, the fins, are bony fin rays and, except the caudal fin, have no direct connection with the spine. They are supported only by the muscles. The ribs attach to the spine.

- Esophagus. The esophagus is a hollow muscular tube that transports saliva, liquids, and foods from the mouth to the stomach. When the patient is upright, the esophagus is usually between 25 to 30 centimeters in length, while its width averages 1.5 to 2 cm.he esophagus passes close to the trachea (breathing tube) and the left side of the heart. This means that problems with the esophagus, such as eating something too hot, can sometimes feel like a pain close to or in the heart or throat.

Mercury in fish The older that such fish become, the more mercury they may have absorbed. Anything that eats these fish within the food chain also consumes the higher level of mercury that the fish have accumulated. This process explains why predatory fish such as swordfish and sharks or birds like osprey and eagles have higher

What is the function of the esophagus? The tube that connects the pharynx (throat) with the stomach. The esophagus lies between the trachea (windpipe) and the spine. It passes down the neck, pierces the diaphragm just to the left of the midline, and joins the cardiac (upper) end of the stomach.he passage food takes from mechanical digestion in the mouth to digestion in the stomach. It's function though is to help and provide a place for the food to travel down to your stomach. It carries the food from the pharynx to the stomach.
