The last Korotkoff sound occurs when the blood pressure is equal to

Diastolic Pressure.

When the left ventricle relaxes, the blood pressure drops to its lowest level, which is called

Diastolic Pressure.

How is the vital capacity calculated?

Goblet Cells

Select all of the following represented by the number of pulses per minute.

Heart Rate Number of Ventricular Contraction Number of Cardiac Cycles

With COPD, there is a decreased air flow from the lungs. This could be caused by which of the following reasons? Select all that apply.

Inflammation of Major and Small Airways Destruction of the Walls between Your Lungs' Air Sacs Excessive Mucus Production

Categorize the following as being associated with either obstructive or restrictive lung disorders.

OBSTRUCTIVE DISORDERS Asthma Bronchitis Heavy Smokers Decreased airflow by bronchoconstriction RESTRICTIVE DISORDERS Neuromuscular Disorders Fibrosis caused by Coal Dust Weakening of Respiratory Muscles Tuberculosis

Place the respiratory structures below in the order that air would pass through them as it moves from the outside to the inside of the body.

OUTSIDE OF BODY Nares Vestibule Nasal cavity Posterior nasal aperture Nasopharynx Oropharynx Laryngopharynx Larynx Trachea Main bronchus Bronchioles Terminal bronchioles Respiratory bronchioles Alveolar ducts Alveolar sacs Alveoli INSIDE OF THE BODY

What opposing forces generate the pressure found within the pleural cavity (intrapleural pressure)? Select all that apply.

Surface Tension caused by the Serous Fluid within the Pleural Cavity Elastic Recoil of the Lungs Tissue Inward Outward Pull of the Thoracic Cage

During the contraction of the left ventricle, the systemic arterial pressure reaches its maximum, which is called

Systolic Pressure.

Drag the label to the term that describes it.

TIDAL VOLUME Amount of air inhaled and exhaled in one cycle of quiet breathing. About 500 mL. INSPIRATORY RESERVE VOLUME Amount of air that can be inhaled with maximum effort. About 3000 mL. EXPIRATORY RESERVE VOLUME Amount of air that can be exhaled with maximum effort. About 1200 mL. RESIDUAL VOLUME Amount of air remaining in the lungs after maximum expiration. About 1300 mL.

Complete each sentence with the correct word.

The RESIDUAL VOLUME is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during normal breathing is called the TIDAL VOLUME. After a normal inspiration, the amount of air that can then be inspired forcefully is called the INSPIRATORY RESERVE VOLUME. The total lung capacity minus the residual volume equals the VITAL CAPACITY. The vital capacity minus the EXPIRATORY RESERVE VOLUME equals the inspiratory capacity. The effects of OBSTRUCTIVE DISEASES, such as asthma or emphysema, may be determined by measuring rapid exhalation with a spirometer.

Complete each sentence by dragging the proper label into the appropriate position.

The highest pressure exerted on the arterial walls during the heart cycle is referred to as SYSTOLIC BLOOD PRESSURE. When one-third of pulse pressure is added to the diastolic pressure, a good estimate of MEAN ARTERIAL PRESSURE is obtained. The DIASTOLIC BLOOD PRESSURE is measured when the heart is relaxing and represents the lowest pressure exerted in the walls of the arteries during the heart cycle. Subtracting the diastolic blood pressure from the systolic blood pressure results in PULSE PRESSURE, which is directly proportional to the overall strength of one's pulse.

Complete each sentence with the correct word.

The total amount of air a person can exhale after filling the lungs completely is called VITAL CAPACITY. It is the sum of three respiratory VOLUMES. TIDAL VOLUME, which is the amount of air inhaled and exhaled in one cycle during quiet breathing. INSPIRATORY RESERVE VOLUME, which is the amount of air in excess of a normal breath that can be inhaled with maximum effort. EXPIRATORY RESERVE VOLUME, which is the amount of air in excess of a normal breath that can be exhaled with maximum effort.

What is the name of the volume of air moved in or out of the lungs during a quiet respiratory cycle?

Tidal Volume

The functions of the respiratory system include all of the following (to supply all cells of the body with oxygen, to maintain the acid-base balance of the body, and to rid the body of carbon dioxide), EXCEPT

To maintain body temperature.

An adult with a blood pressure of 130/95 would have mild hypertension.

True.

Which of the following blood vessels have the lowest pressures?

Veins
