• The pancreas is an organ that produces digestive enzymes.
• The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens and foreign invaders.
• The immune system also has the ability to remember past invaders, allowing for a faster and more effective response upon subsequent exposure.
• White blood cells, such as lymphocytes and phagocytes, play a crucial role in identifying and destroying pathogens in the body.
• Digestion begins with the mechanical breakdown of food by chewing, which mixes it with saliva containing amylase to begin starch hydrolysis.
• Digestion begins with the mechanical breakdown of food by chewing, which increases its surface area to be acted upon by salivary amylase.
• Saliva contains salivary amylase, which breaks down starch into maltose.
• Food then passes through the oesophagus into the stomach where gastric juice containing HCl and proteases breaks down protein molecules.
• The pancreas is an organ that produces digestive enzymes.
• Food then passes through the oesophagus (gullet) into the stomach.
