Question

Describe the functions of the following: A) Saliva B)Oesophagus C)Tongue D)Liver ​

Answer 1

a.The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

b.The esophagus is made of muscles that contract to move food to the stomach. This process is called peristalsis, according to the Cleveland Clinic.

c.The tongue is the most important articulator of speech. This muscle is extremely strong, as it must move food around in our mouths as we chew. Its other biological function is to push the food into a bolus (I prefer the less scientific term "glob"), and then push it down the oesophagus to our stomach

d.The primary functions of the liver are:

Bile production and excretion.

Excretion of bilirubin, cholesterol, hormones, and drugs.

Metabolism of fats, proteins, and carbohydrates.

Enzyme activation.

Storage of glycogen, vitamins, and minerals.

Synthesis of plasma proteins, such as albumin, and clotting factors

Answer 2

Answer:

oesophagus helps to pass the food from mouth to stomach

Tongue mixes the food with saliva completely so in order to pass the soluble food through oesophagus

saliva produces salivary any laws

saliva makes food soluble by being mixed by the help of tongue

liver produces bile, which stores in gall bladder

it produces enzymes to break down food into soluble particles
