Alimentary Canal Anatomy Quiz

Digestive System

• Muscular contractions and relaxations, known as peristalsis, are responsible for moving food from one part of the alimentary canal to the next.

Digestive Organs

• The main function of the digestive organs is to break down food into smaller molecules that can be absorbed and utilized by the body.

Pancreas

• The pancreas is the organ responsible for producing digestive juices that reach the intestine through small tubes known as ducts.

Small Intestine

• The small intestine contains tiny glands that produce juices to help digest food.

Absorption and Excretion

• The process that converts waste into excretable material in the digestive system is known as absorption.

Lymphatic System

• The main function of the lymphatic system is to defend the body against disease-causing organisms and to aid in the removal of waste products.

Lymph Fluid

• Lymph fluid is composed of water, salts, sugars, fats, and proteins.
• Lymph fluid drains into the lymphatic vessels before reaching the lymph nodes or glands.

Lymphocytes and Monocytes

• Lymphocytes and monocytes carried by lymph fluid play a crucial role in defending the body against disease-causing organisms.

Lymph capillaries

• Lymph capillaries merge to form larger lymph vessels, which eventually drain into the bloodstream.

Saliva

• The main function of saliva in the digestive system is to break down carbohydrates into simple sugars.

Pharynx

• The pharynx plays a crucial role in the digestive process by facilitating the passage of food from the mouth to the oesophagus.

Oesophagus

• The oesophagus is a muscular tube that uses peristalsis to propel food into the stomach.

Peristalsis

• The primary purpose of peristalsis in the digestive system is to mix food with digestive enzymes and to move it through the alimentary canal.
