9.01 Brings oxygenated air to the alveoli. Removes air containing carbon dioxide. Filters‚ warms‚ and humidifies the air. Produces sound (speech). Helps with sense of smell. Assists to regulate the pH within the blood. 9.02 Nose- Nares/Nostrils- Allow entrance for air. Nasal Cavity- Lined with mucous & ciliated epithelium. Air is filtered‚ warmed‚ and humidified. Nasopharynx- Part of the throat serving only as a passageway for air. Pharynx- Throat. 3 Passageways that serve for air

Determining the Latent Period 1. Click Clear Tracings to erase the oscilloscope display. The voltage should be set to 5.0 volts. 2. Drag the 200 msec button to the right edge of the oscilloscope. 3. Click the Stimulate button once‚ and allow the tracing to complete. 4. When you measure the length of the latent period from a printed graph‚ you measure the time between the application of the stimulus and the beginning of the first observable response(increase in force). The computer can’t “look ahead

An Analysis of the Main Causes of Cardiovascular Diseases There are a great number of diseases such as cancer and HIV around the world. However‚ cardiovascular disease (CVD) is now arousing public attention due to its increasing effect on populations. ‘Cardiovascular disease (CVD) is the name for the group of disorders of heart and blood vessels such as hypertension‚ coronary heart disease‚ stroke‚ and peripheral vascular diseases’ (WHO‚ 2012). CVD has enormous impacts on health and kills an estimated

Activity 1 1. Size and concentration of the solute 2. It was too large to pass‚ as predicted 3. I predicted that the glucose would diffuse since it is small enough but the albumin is much too large to pass through the membrane. The experiment produced this result. Activity 2 1. Neither way requires ATP but facilitated diffusion requires carrier protein molecules for diffusion to occur. 2. By increasing the number of carriers more glucose can pass at a time increasing the rate‚
