Question

After fast running, man has a fast heartbeat, slow pulse, and shallow breathing, in such condition he has
A. Oxygen debt
B. Poisoning due to lactic acid
C. No pulmonary pressure
D. Weak heart

Answer 1

The respiratory system can be defined as the network of organs and tissues functioning cumulatively to perform an exchange of oxygen and carbon dioxide. The organs distinctively working as the respiratory system include the nose, mouth, pharynx (throat), larynx (voice box), trachea (windpipe), bronchi, and the most important organs the lungs.

Step by step answer: Based on the physiology, respiration can be defined as the exchange of gases, i.e. movement of oxygen from the external environment into the cells of the body present within the tissue, and the transport of carbon dioxide gas outside the body. The exchange of gases involves inhalation and exhalation. Inhalation is the action of breathing in the air into the lungs, whereas exhalation is the action of breathing out air.
-Oxygen debt is a term to determine the stage in the body, when a person takes part in any physical activity, such as exercising or running in this case, the rate of supply of oxygen by the lungs to the muscle decreases. This results in the production and accumulation of lactic acids in the muscle. It does not necessarily cause lactic acid poisoning and only accumulates in muscle. This results in shallow breathing so as to increase the rate of intake of oxygen gas into the lungs.
-Pulmonary pressure is a type of hypertension (high blood pressure). This affects the lungs and heart arteries. Symptoms of pulmonary pressure include chest pressures, dizziness and shortness of breath. Pulmonary pressure is a condition that worsens over time and requires oxygen therapy and medication to treat the symptoms. This does not occur due to physical activity such as running.
-A weak heart is a state where the blood is not pumped efficiently enough to provide oxygen to other parts of the body. This occurs due to weak cardiac muscles, which can sometimes be dilated or stiffened. Over time, the heart loses its functioning capabilities and workload. The symptoms correlated with a weakened heart involve, lack of energy, dizziness, fainting, inflammation of the feet and ankles, abdominal bloating due to fluid build-up, shortness of breath, and coughing while laying down.
In conclusion, during exercise, the body requires more oxygen. Due to this, there is shortness of breath. And because exercising releases lactic acid in the muscle, more oxygen is essential to breakdown the accumulated lactic acid. Therefore the condition, where the man has a fast heartbeat, slow pulse, and shallow breathing due to fast running is called oxygen debt.
The correct answer is A. Oxygen debt

Note: The respiratory system apart from providing oxygen to the body, assists in cleaning out waste gases such as carbon dioxide from the muscles. Exercising is an essential part of life. It helps maintain physical strength and boost stamina. Exercise increases the quality of life.
