The digested food can now pass into the blood vessels in the wall of the intestine. This process is called absorption. The inner walls of the small intestine have thousands of finger -like outgrowths. These are called villi (singular villus).The villi increase the surface area for absorption of the digested food.
The small intestine contains a number of receptive cells which detect the presence of macronutrients and secrete hormones which instructs the pancreas on how much insulin and glucagon to release.

The reaction of an acid with a base to give salt, water and heat is called neutralisation.
Example: Hydrochloric Acid + Sodium Hydroxide → Sodium Chloride + Water + Heat
HCl + NaOH → NaCl + H2O + Heat
The heat evolved in the neutralisation reaction raises the temperature of the reaction mixture.
Example: During the mixing of dilute sulphuric acid with potassium hydroxide, the test tube heats up.
