Question

1- In an electrocardiogram (EKG), the .......wave denotes repolarization of the ventricles.

2- Within the following list, type your response for which is part of the conducting portion of the lower respiratory tract: respiratory bronchioles, terminal bronchioles, alveoli, or alveolar ducts.

Answer 1

1. ANSWER- T WAVE.

EXPLANATION-  The T wave represents the repolarization of the ventricles. This means that the ventricles are relaxed and under less pressure.

2. ANSWER- terminal bronchioles

EXPLANATION-   the respiratory system is separated into a conducting zone and respiratory zone. conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.

The terminal bronchiole is the most distal segment of the conducting zone. It branches off the lesser bronchioles. Each of the terminal bronchioles divides to form respiratory bronchioles which contain a small number of alveoli.

GOOD LUCK!
