Explanation
Teeth are similar to bone and contain a mineralized matrix called Enamel . It is the hard, outer layer of teeth that protects them from decay and damage.

Explanation
Teeth are responsible for biting, chewing, crushing, and grinding food into smaller pieces , making it easier to swallow and digest.

Explanation
The stomach secretes stomach juices , also known as gastric juices , which contain digestive enzymes and acids that break down proteins, carbohydrates, and fats into smaller molecules. These juices help to digest food in the stomach.

Explanation
The stomach mixes food with digestive enzymes and acids. It churning and blending it into a liquid mixture called chyme. Much like a mixer combines ingredients together.

Explanation
Digestion begins in the mouth , where food is chewed and mixed with saliva that contains enzymes to break down carbohydrates.  Here's a brief overview of the digestion process: Mouth : Food is chewed and mixed with saliva that contains enzymes to break down carbohydrates. Esophagus : Food is swallowed and passes through the esophagus into the stomach. Stomach : Food is mixed with stomach acid and enzymes to break down proteins and fats. Small Intestine : Nutrients are absorbed into the bloodstream. Large Intestine : Water and electrolytes are absorbed, and waste is eliminated.

Explanation
The stomach's main functions are: Storage : Holds food temporarily Mechanical and chemical breakdown : Mixes and digests food with enzymes and acids Liquification : Converts food into a liquid mixture (chyme) Emptying : Releases chyme into the small intestine for nutrient absorption

Explanation
The stomach is a J shaped sac about one foot in length that lies under the diaphragm on the left of the abdominal cavity. The stomach has three parts : The region where the stomach opens is known as the cardiac stomach. The main body is known as fundus . The posterior portion which opens to the intestine is known as the pyloric stomach.

Explanation
When you swallow food, sweets, or drinks, they pass through the esophagus and enter the stomach. Where they are mixed with digestive enzymes and acids to break down proteins, carbohydrates, and fats.

Explanation
Most headaches are caused by irritation or inflammation of the nerves in the head and neck, rather than the brain itself. This can be due to various factors such as tension, stress, or medical conditions.

Explanation
The adult human brain weighs about 3 pounds (1,300-1,400 g). The adult human brain is about 2% of the total body weight. The average human brain is 140 mm wide. The average human brain is 167 mm long.

Science is the systematic study of the nature and behavior of the material and physical universe , based on observation, experiment, and measurement, and the formulation of laws to describe these facts in general terms.

Explanation
The word ‘ Scientia ’ is derived from the Latin word Scientia which means ‘ knowledge ’. It is the field of human knowledge concerned with facts that are explained logically by rules, patterns, or principles.
