Because we wanted to focus specifically on “speed” rather than general measures of quality, we custom-designed a scale to rank schools based on this highly desirable “fast factor.” Specifically, we researched each online college and asked ourselves the following questions: Does the school offer bachelor’s degrees that one could complete in less than four years? What about associate’s degrees in less than two years? Are there many short certificate options for students who want to quickly augment their skills in an established field? Are there “accelerated” degree paths and options for students who want to earn a combined bachelor’s/master’s degree? Does the school offer credit for life/work experience and past academic coursework in order to help students move ahead on their degree path? Does the school offer multiple course formats so that students have the option to start several times a year and/or to choose between classes of varying lengths? But don’t worry – we still considered graduation rate and tuition costs as well! We hope this has been helpful in providing information about fast online degrees from accredited colleges. There are many fast online degree programs available, and we encourage you to do a broad search to find the program that’s best for you.

Bernapas yaitu kegiatan yang amat penting untuk keberlangsungan hidup semua makhluk hidup, terutama manusia. Bila seorang manusia tidak bernapas cuma selama beberapa saat, bakal segera terjadi perubahan menyeluruh didalam badannya, seperti perubahan respirasi aerob bakal jadi respirasi anaerob. Jelas saja perubahan ini bakal berakibat tidak baik untuk individu itu.

Malignant peritoneal mesothelioma is a rare type of mesothelioma which attacks the lining of abdomen also known as peritoneum. Malignant peritoneal mesothelioma (MPM) is a universally fatal disease affecting 20% to 30% of the mesothelioma cases. It's was first described by Miller and Wynn in the year 1908. According to the statistics, in the past two decades, the incidence of malignant peritoneal mesothelioma cancer has increased. Peritoneal mesothelioma affects the lining of the abdomen also known as peritoneum. The location of malignant cell is human's abdominal lining and because of that, MPM can sometimes known as abdominal mesothelioma. However, most common term used to describe this type of cancer is peritoneal mesothelioma. The main cause of MPM in humans is asbestos. Asbestos typically is the one of most commonly roofing materials since it is not only cheaper but is easy to fix on a roof. Asbestos exposure contributed to almost 70 to 80 percent of mesothelioma lung cancer. Humans come into contact with asbestos when they swallow or inhale the fibers. Asbestos inhalation may increase risk to develop asbestos related diseases, most importantly mesothelioma. Asbestos was completely banned in UK since it was recognized to be a serious health hazard, and it is now responsible for about 4000 deaths each year and many cases of serious disease. The people at increase risk of developing health asbestos related disease are those whose work brings them into direct contact with asbestos such as builders, heating engineers, roofers and demolition workers. In addition to mesothelioma, asbestos exposure will increase the risk of other health problems such as lung cancer, asbestosis (chronic lung ailment) and other type of cancer such as larynx and kidney cancer. Symptoms of Malignant Peritoneal Mesothelioma It can takes such a long time for cancer to develop the symptoms and sometimes may take up to 30 years, between exposure to asbestos and the start of the disease. Most common symptoms of the disease are abdominal pain, abdominal swelling, abnormal weight loss, anemia, easy fatigue, nausea and vomiting. Abdominal pain and swelling result from fluid accumulation in the abdominal cavity. Other than that, people can easily get fever when the disease starts to shows its symptoms. Among the symptoms stated above, abdominal pain is the most common reported initial symptoms of MPM. Unexplained night sweats and blood coagulation problems are less frequent symptoms occurring when the cancer develops. If the cancer cells spread to the other part of the body, the symptoms may lead to trouble swallowing or swelling of the neck and face. Diagnosis of Abdominal Mesothelioma It is very difficult to diagnose peritoneal mesothelioma since there is no defined system so far that can differentiate the stages of the development of cancerous tumor cells. If required, TNM staging system normally used to detect the cancer in stages. Other than that, Serum mesothelin-related protein (SMRP) may be a potentially useful serum marker used to diagnose and to follow-up the cancer progression. Computer tomography (CT) findings may be a useful tool in detection and characterization of peritoneal mass. Malignant Peritoneal Mesothelioma is a deadly neoplasm. MPM's diagnosis is difficult to perform since the symptoms will take a long time to show up. Early detection is the key in peritoneal mesothelioma treatment since the cancer cell normally spread very fast. Peritoneal Mesothelioma can be regarded as a very dangerous cancer among other cancer.However we can prevent this problems from occur to you and your family. As i said before, early detection is the key of peritoneal mesothelioma treatment [] success since the cancer cell spread very fast.

Alat Pernafasan Manusia

Rongga Hidung (cavum nasal)

Rongga hidung terbagi jadi dua sisi oleh septum nasalis, yakni sisi kiri serta kanan. Sisi depan septum dibentuk oleh tulang rawan, sedangkan sisi belakang dibentuk oleh tulang vomer serta tonjolan tulang ethmoid.

Pada dinding lateral ada tiga tonjolan yang disebut dengan konka nasalis superior, konka media serta konka inferior. Lewat celah pada ketiga tonjolan ini, udara yang dihirup bakal dihangatkan oleh pembuluh darah kapiler yang melewati celah ini dan dilembabkan oleh lendir yang di keluarkan oleh sel goblet (sel penghasil lendir). Lendir ini dapat juga membersihkan udara yang masuk dari debu.

Sisi atas rongga hidung ada daerah olfaktorius, yang memiliki kandungan beberapa sel saraf sensoris pembau. Beberapa sel ini terkait dengan saraf kranial yang pertama yakni nervus olfaktorius.

Panjang rongga hidung kurang lebih 10 cm. Udara yang masuk lewat rongga hidung lantas dialirkan ke paru-paru. Umumnya dalam satu hari kurang lebih 15. 000 liter udara masuk lewat hidung.

Manfaat rongga hidung yaitu:

  • Penyaringan udara, yakni benda-benda asing yang berbentuk selain gas, umpamanya debu. Benda-benda itu disaring oleh rambut-rambut halus yang tumbuh ke arah luar lubang hidung.
  • Penghangatan, yakni merubah suhu udara supaya sesuai dengan suhu tubuh lewat celah-celah konka nasalis.
  • Melembabkan udara, oleh karena adanya lendir, air bakal diuapkan untuk melembabkan udara. Udara yang masuk ke paru-paru umumnya mempunyai kelembapan sebesar ± 80%.


  • Faring adalah persimpangan antara saluran pernafasan dengan saluran pencernaan. Didalam faring ada organ:
  • Epiglotis, bertugas mengatur masuknya makanan ke saluran pencernaan serta udara ke saluran pernafasan.
  • Epiglotis bekerja seperti katup yang bakal membuka serta menutup. Ia bakal membuka saat udara masuk untuk dialirkan ke trakea, serta bakal menutup ketika makanan masuk agar tidak masuk ke saluran pernafasan.
  • Dibawah faring ada laring (pangkal tenggorokan).
  • Pada laring ada celah yang disebut dengan glotis yang menuju ke batang tenggorokan, pita suara ada didalam laring.


Trakea berbentuk satu tabung yang terdapat di leher serta disusun oleh tulang rawan yang berupa cincin dengan panjang kurang lebih 10 cm. Dinding trakea disusun oleh jaringan ikat serta otot polos dan ada rambut-rambut halus yang berperan untuk mengeluarkan debu serta kotoran. Rambut-rambut halus ini bergerak dari bawah ke atas, hingga kotoran bakal bergerak ke atas. Di bagian bawah, trakea bakal bercabang dua serta disebut dengan sebagai bronkus, yang menuju paru-paru kiri serta kanan.


bronkus terdiri dari bronkus kanan serta kiri. Bronkus kanan terletak lebih vertikal dari pada kiri, hingga bronkus kanan akan lebih gampang kemasukan benda asing, yang mengakibatkan seseorang akan lebih gampang terkena penyakit bronkitis.

Dinding bronkus terdiri atas 3 lapis, yakni jaringan ikat, otot polos, serta jaringan epitel. Pada bronkus, cincin tulang rawan tidak berupa lingkar sempurna dibandingkan dengan trakea.


Yaitu cabang dari bronkus. Bronkiolus bakal bercabang-bcabang jadi saluran yang lebih halus yang bakal berakhir di alveolus. Beberapa sel epitel bersilia (silia : rambut-rambut halus) bakal berubah jadi sisik epitel.


Paru-paru manusia berjumlah sepasang, yakni paru-paru kanan serta kiri. Organ ini terdapat didalam rongga dada. Paru-paru kanan mempunyai berat kurang lebih 620 gr, sedangkan paru-paru kiri kurang lebih 560 gr. Ini disebabkan karena paru-paru kanan mempunyai tiga bronkiolus, sedangkan paru-paru kiri cuma memiliki 2 bronkiolus.

Paru-paru diselubungi oleh pleura yang terdiri dari dua susunan. Diantara susunan pleura ini ada cairan limfe yang berperan untuk mengurangi gesekan ketika paru-paru mengembang serta mengempis.


Alveolus adalah saluran akhir dari alat pernafasan. Alveolus berbentuk gelembung-gelembung udara. Di bagian alveolus inilah terjadi pertukaran O2 dari udara bebas ke beberapa sel darah, serta CO2 dari beberapa sel darah ke udara bebas.
