Produce saliva. They also secrete amylase, an enzyme that breaks down starch into maltose.

An organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. During swallowing, food passes from the mouth through the pharynx into the esophagus and travels via peristalsis to the stomach

The epiglottis is a flap that is made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally

Located between the esophagus and the small intestine. It secretes protein-digesting enzymes and strong acids to aid in food digestion, through smooth muscular contortions before sending partially digested food (chyme) to the small intestines

Primary function of the small intestine is the absorption of nutrients and minerals found in food

It has a wide range of functions, including detoxification, protein synthesis, and production of biochemicals necessary for digestion

A small organ that aids mainly in fat digestion and concentrates bile produced by the liver

A glandular organ in the digestive system. Produces several important hormones, including insulin, glucagon, and pancreatic polypeptide, and a digestive organ. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.

Acts as a temporary storage site for feces. As the rectal walls expand due to the materials filling it from within, stretch receptors from the nervous system located in the rectal walls stimulate the desire to defecate.

Receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve.

It receives deoxygenated blood from the superior and inferior vena cava and the coronary sinus, and pumps it into the right ventricle through the tricuspid valve

It receives oxygenated blood from the left atrium via the mitral valve, and pumps it into the aorta via the aortic valve

It receives deoxygenated blood from the right atrium via the tricuspid valve, and pumps it into the pulmonary artery via the pulmonary valve and pulmonary trunk. It is triangular in form, and extends from the right atrium to near the apex of the heart.

Question	Answer
Salivary Gland	Produce saliva. They also secrete amylase, an enzyme that breaks down starch into maltose.
Esophagus	An organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. During swallowing, food passes from the mouth through the pharynx into the esophagus and travels via peristalsis to the stomach
Epiglottis	The epiglottis is a flap that is made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally
Stomach	Located between the esophagus and the small intestine. It secretes protein-digesting enzymes and strong acids to aid in food digestion, through smooth muscular contortions before sending partially digested food (chyme) to the small intestines
Small Intestine	Primary function of the small intestine is the absorption of nutrients and minerals found in food
Liver	It has a wide range of functions, including detoxification, protein synthesis, and production of biochemicals necessary for digestion
Gallbladder	A small organ that aids mainly in fat digestion and concentrates bile produced by the liver
Pancreas	A glandular organ in the digestive system. Produces several important hormones, including insulin, glucagon, and pancreatic polypeptide, and a digestive organ. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.
Rectum	Acts as a temporary storage site for feces. As the rectal walls expand due to the materials filling it from within, stretch receptors from the nervous system located in the rectal walls stimulate the desire to defecate.
Left Atrium	Receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve.
Right Atrium	It receives deoxygenated blood from the superior and inferior vena cava and the coronary sinus, and pumps it into the right ventricle through the tricuspid valve
Left Ventricle	It receives oxygenated blood from the left atrium via the mitral valve, and pumps it into the aorta via the aortic valve
Right Ventricle	It receives deoxygenated blood from the right atrium via the tricuspid valve, and pumps it into the pulmonary artery via the pulmonary valve and pulmonary trunk. It is triangular in form, and extends from the right atrium to near the apex of the heart.
