Sphincters are muscular valves found throughout the body used to open or close an opening. An example is the cardiac sphincter which prevents food from coming back up the esophagus after swallowing
Where is the esophageal sphincter located?
Anatomic location The anterior muscles include the superior and inferior hyoid muscles. The superior hyoid muscles include the geniohyoideus, mylohyoideus, stylohyoideus, hyoglossus, and anterior belly of the digastricus. These muscles arise from various structures superior to the hyoid bone and insert onto the superior aspect of the hyoid bone.

Bolus is food that has been broken down in the mouth. It can be found in the mouth after chewing, in the esophagus, and in the stomach before digestion. Chyme is food that has been broken down in the stomach and small intestine. It can be found in the stomach after digestion, the small intestine, and the large intestine before it becomes feces.

To hold the food within the stomach there are two valves. At the top of the stomach is the lower esophageal sphincter (LES) which prevents backsplash of stomach contents upward into the esophagus. At the bottom of the stomach is the pyloric which controls the "drain" of the stomach.
Do sheep have a cardiac sphincter?
Yes, they would have to, otherwise the digesta from the rumen and reticulum would be free come up if the stomach compartments get quite full. It is found at the junction between the esophagus and the ruminal/reticular junction. When a bolus of cud is to be regurgitated, the sphincter muscle relaxes and allows the cud to come up to be chewed, and relaxes again to allow the rechewed bolus to be returned to the rumen. Cardiac sphincters are also found between most of the chambers in the ruminant animal for the same reason as stated above. Check out the three sources below for further information and pictures for proof:

How the food is prevented from going back into the oesophagus?
Willpower and disgust. Once the food is outside your body, you do not normally want to eat it again. Disgust prevents most people from doing this, but if you do not feel that naturally, you have to use willpower. Some animals eat their own feces so the food does re-enter the esophagus at least once. This is called 'coprophagy' and is important for animals that need to digest food twice. There are also animals called 'ruminants' who send the food back into their mouths for a second chewing, so their food passes through the esophagus three times - down, then back up, then back down again.

What are the circular bands of muscle at each end of the stomach?
These rings of muscle are not only found either end of the stomach, but also at the base of the bladder. They are called sphincters. The lower sphincter in the stomach is specifically known as the pyloric sphincter, but I regret to say I do not know the exact names given to other sphincters.

What is the role of the esophagus?
It is a tube that connects the pharynx (throat) with the stomach. It passes down the neck, pierces the diaphragm just to the left of the midline, and joins the cardiac (upper) end of the stomach. When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and facilitates swallowing.The main function of the esophagus is a tube that connects our mouth to the stomach. it is also known as the gullet. The word esophagus comes from a greek word which means to carry what is eaten.The esophagus is your food tube. Your trachea is our tube for air.
