Vital capacity is defined as

• amount of air inspired and expired with each normal breath during rest or exercise.

• is the greatest amount of air that can be made to pass into and out of the lungs by the most forceful inspiration and expiration.

• the delivery of oxygen from the lungs to the bloodstream.

• the movement of air from outside the body into the cells within tissues.

Tidal volume is defined as

• amount of air inspired and expired with each normal breath during rest or exercise.

• is the greatest amount of air that can be made to pass into and out of the lungs by the most forceful inspiration and expiration.

• the delivery of oxygen from the lungs to the bloodstream.

• the movement of air from outside the body into the cells within tissues.

Gaseous exchange is defined as

• amount of air inspired and expired with each normal breath during rest or exercise.

• is the greatest amount of air that can be made to pass into and out of the lungs by the most forceful inspiration and expiration.

• the delivery of oxygen from the lungs to the bloodstream and the removal of carbon dioxide from the tissues.

• the movement of air from outside the body into the cells within tissues.

The diaphragm is defined as

• the primary muscle used in the process of inspiration. A dome shaped muscle.

• the tube that takes air into the chest, also known as the windpipe.

• tiny sacs at the end of the bronchioles, where gaseous exchange takes place.

The bronchus (bronchi) are defined as

• the primary muscle used in the process of inspiration. A dome shaped muscle.

• the tube that takes air into the chest, also known as the windpipe.

• tube along which air passes from the trachea into the lungs.

• a type of protein found in every red blood cell.

Define oxygen debt

• The amount of oxygen needed at the end of a physical activity to break down any lactic acid.

• working at a high intensity level without oxygen for energy production.

• the volume of oxygen an athlete can consume while exercising at maximum capacity.

• smaller branches coming off the bronchi.
