When Elaine turned three‚ something disastrous had happened to Mei. She had been diagnosed with a type of throat cancer‚ laryngectomy. Mei had her larynx taken out‚ so now she can no longer talk. Because it is crucial for a young child to learn how to talk during their early years‚ Mei and her husband decided to send Elaine to Hong Kong‚ where Mei’s sister lives. Mei’s sister taught Elaine Cantonese

ciliated epithelium rich in blood capillaries. This passage is hairy. When the air passes through the nose‚ certain amount of dust of the air is trapped and the air is warmed up. Behind the nasal passage is the vocal sac or the larynx. It is called Adam’s apple. Behind the larynx is a wind pipe called the trachea. It is a 12-cm long tube whose diameter is about 16mm. it is surrounded by incomplete rings of cartilages. As the air passes down the trachea‚ it becomes humidified‚ because some moisture from

Most sore throats are cauesd by a viral infection‚ such as the cold or flu. Some viruses can cause specific types of sore throat‚ such as coxsackie infection or mononucleosis. Bacteria that can cause pharyngitis include Group A streptococcus‚

are closely associated with the circulatory system as they perform the excretory function of removing waste from the blood. Recognize that kidneys remove nitrogenous wastes‚ and the liver removes many toxic compounds from blood. Explain how the respiratory system (nose‚ pharynx‚ larynx‚ trachea‚ lungs‚ alveoli) provides exchange of oxygen and carbon dioxide.

The respiratory system carries out gas exchange; major organs in the system include: the nose‚ pharynx‚ larynx‚ trachea‚ bronchi‚ and lungs. The major function of the respiratory system is to supply the body with oxygen and dispose of carbon dioxide. In order for this to happen‚ at least four events called respiration must occur. The first is the pulmonary ventilation. The air must move in and out of the lungs so that the gases in the alveoli are continuously refreshed. This process is better known

Pain is a notoriously difficult symptom for doctors to evaluate‚ because every patient experiences and describes pain differently. This poses a challenge when diagnosing conditions such as fibromyalgia for which pain is a primary symptom. Doctors have learned‚ however‚ that fibromyalgia patients tend to experience pain in certain parts of the body‚ referred to as "tender points." There are nine pairs of tender points throughout the body‚ or 18 in total. The American College of Rheumetology suggests

were warm-blooded‚ 4 limbed primates that lived over 7 million years ago. However‚ what really established the basis of humans was the ability of bipedalism walking upright on 2 legs‚ having opposable thumbs to manipulate objects‚ and a voice box larynx that was much lower in the neck for communicating. Walking on two legs gave the perks of using less energy while being able to carry items typically food over large distances. Humans evolved from the groups of “homo” meaning the same.

There are several hundred PAHs‚ which usually occur as complex mixtures rather than as individual compounds. Benzo (a) pyrene is the most widely studied‚ being one of the most potent‚ hence most of the data in this document refers to B(a)P‚ although it seldom occurs in the environment on its own. For the general public‚ the main route of exposure to PAHs is from inhalation of ambient and indoor air or ingestion of food. Inhalation and skin absorption are the main routes of occupational exposure.

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable
