Pharynx?






Accoding to Wikipedia, pharynx 咽喉means this.

The pharynx (plural: pharynges) is the part of the neck and throat situated immediately posterior to the mouth and nasal cavity, and cranial, or superior, to the esophagus, larynx, and trachea.

Functions
It is part of the
digestive system and respiratory system of many organisms.
Because both
food and air pass through the pharynx, a flap of connective tissue called the epiglottis closes over the trachea when food is swallowed to prevent choking or aspiration. In humans the pharynx is important in vocalization.

Parts
The human pharynx is conventionally divided into three sections:

Oropharynx
The
oropharynx lies behind the oral cavity. The anterior wall consists of the base of the tongue and the vallecula; the lateral wall is made up of the tonsil, tonsillar fossa, and tonsillar (faucial) pillars; the superior wall consists of the inferior surface of the soft palate and the uvula.

Nasopharynx
The
nasopharynx lies behind the nasal cavity.
Postero-superiorly this extends from the level of the junction of the hard and soft palates to the base of skull, laterally to include the
fossa of Rosenmuller.
The inferior wall consists of the superior surface of the soft palate.

Hypopharynx
The
hypopharynx, laryngopharynx roughly corresponds to the levels between C3 to C6, it includes the pharyngo-esophageal junction (postcricoid area), the piriform sinus, and the posterior pharyngeal wall.
Like the oropharynx above it the hypopharynx serves as a passageway for food and air and is lined with a
stratified squamous epithelium.
It lies directly anterior to the upright epiglottis and extends to the larynx, where the respiratory and digestive pathways diverge.
At that point the laryngopharynx is continuous with the esophagus posteriorly. The esophagus conducts food and fluids to the
stomach; air enters the larynx anteriorly. During swallowing, food has the "right of way", and air passage temporarily stops.

Why do I talk about pharynx? I think for the next few months this will be a very hot topic in my cellgroup and church. A lot of people still has very little understanding about it but this will change soon. The reason, she had a tumour in pharynx.
The news come as a shock for all of us last night. For me, this is the second cases happen right in front of my eyes in the space of 6 months. Ironically, both of these wonderful faithful daughter of God have demostrate tremendeus strengh, faith and long suffering in facing this difficult situation. They have the faith and peace that God is with them and God had healed them. Personally, I really don't know if I will have this type of faith.
Fighting cancer/tumour is a long ugly battle. It's not only involve in physical but mentally strength as well. Change of diet and lifestyle are requered. The side effects of tumour treatment are sometimes unbarable. The finances that is needed will not be a small amount. All this will affect the family.
Sometimes it is really fructrating to read that we have spend billions of money to search for some organism or planet in the outer space that we are not even sure the real benefits of it but yet we know so little about our own body. About taking care of this only body God had given to us.
We believe God let it happen for a reason, and He will turn even the worst for the good of people who believe in Him. I think for me, at least I no longer ask the question of why? Why bad things happen to good people? Why God allow suffering and pain? Because I know, I will not have an answer.

When there is no answer, there is Jesus.
