Question

When oxygen supply to the tissue is inadequate, the condition is
A. Dyspnea
B. Hypoxia
C. Asphyxia
D. Apnea

Answer 1

Oxygen plays an essential role in the body of human beings by driving various metabolic activities including respiration, producing energy, etc. Oxygen charges our body cells and provides different building blocks needed by our body to survive.

Complete answer:
A. Dyspnea is a medical condition that refers to shortness of breath occasionally described as air hunger and a sophisticated feeling. Its severity may range from mild to temporary or serious to long-lasting. Signs and symptoms experienced by an individual include chest tightness, wheezing, etc.
B. Hypoxia is a medical condition where oxygen supply to the tissue is not in an adequate amount generally occurring because of insufficient oxygen concentration in the blood. Depending upon the supply of oxygen or complete deprivation of oxygen to the body or different body parts, hypoxia is categorized as local (affecting a specific part of the body) or generalized (affecting the whole body). Symptoms experienced by an individual involve an increase in heart rate, rapid breathing.
C. Asphyxia is a condition where a lack of oxygen or excess of carbon dioxide in the body leads to a state of unconsciousness or often leads to death. It occurs due to an inadequate concentration of oxygen in the brain or when the air pathway is blocked physically or as an effect of an injury or by some other medical conditions. Symptoms experienced by an individual involve low heart rate, visual changes, etc.
D. Apnea is a serious sleeping disorder where an individual's breathing is interrupted while sleeping. Patients with untreated sleep apnea stop breathing frequently while sleeping and it means that the brain and rest part of the body is not having an adequate supply of oxygen. Health problems related to untreated sleep apnea persons include stroke, irregular heartbeats, etc.

Hence, the correct answer is option (B).

Note: Oxygen is needed for different biological processes, our body requires sufficient supply of oxygen to manage all the functioning example cells utilize food and oxygen to generate ATP (Adenosine triphosphate) energy source of the cell to power up various cell functions. Inadequate supply of oxygen leads to serious medical conditions or sometimes lead to death.
