CSEC Biology and HSB Notes

SYLLABUS REFERENCE  CSEC HSB [B1.14] relate the types of teeth present in an infant and an adult human to their roles;  [B1.15] explain the importance of teeth in the process of digestion;  [B1.16] relate the structures of the tooth to their functions;  [B1.17] state the causes of tooth decay;  [B1.19] outline guidelines for the care of the teeth;  CSEC BIOLOGY  [B2.7] relate the structures of the human alimentary canal to their functions;  simple diagrams of the internal structure of a tooth required. Mastication and the role of teeth in the mechanical breakdown of food to be included. 

SYLLABUS REFERENCE  HSB [B1.20] explain the properties, role and importance of enzymes involved in digestion; [B1.21] investigate the effects of temperature and pH on the activity of the enzymes amylase and catalase in the digestive process;  CSEC BIOLOGY [B2.8] explain the role and importance of enzymes; [B2.9] investigate the effect of temperature and pH on the activity of the enzymes catalase or amylase; 

SYLLABUS REFERENCE HSB  [B1.22] identify the various structures of the digestive system;  [B1.23] relate the structures of the digestive system to their functions;  [B1.24] describe the processes of digestion and absorption of food in the alimentary canal;  [B1.25] discuss the fate of the products of digestion after their absorption;  [B1.26] relate the structure of a villus to the function of absorption;  BIOLOGY [B2.7] relate the structures of the human alimentary canal to their functions;  [B2.8] explain the role and importance of enzymes;  [B2.10] describe what happens to the products of digestion after their absorption;
