There are basically 3 types of pharynx- nasopharynx, oropharynx and laryngopharynx.
The function of the pharynx are:-
1. To transport the food from mouth to esophagus.
2. To warm, moisten and filter the air, before it moves to the trachea, and then to the bronchi, the bronchioles, the alveoli and at last to the lungs.
Therefore, pharynx(or throat) is a part of both- digestive and respiratory systems.
3. It is also important for vocalization.
The heart begins its work approximately 21 days after conception. As a single cell pump, it will soon develop into four distinct chambers. It becomes the muscle; all other muscles depend to do their work. Beating on an average day 115,000 times, about 200 gallons of blood is pumped into arteries and veins traveling an unprecedented 12,000 miles a day while overcoming gravity to provide nutrients to every organ, muscle, nerve, and tissue.
It is the force of the hearts contraction that maintains our blood pressure; allowing us to breathe and exchange gases at all levels of respiration, ensuring oxygen is provided to all cells of the body, and waste products are eliminated.
