Study Notes
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.
