What happens to oxygen during exercise?

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

How does the body increase its oxygen supply during exercise?

Vasodilation of the arterial tree results in increased blood flow, which carries more oxygen to the tissues per unit time. In addition, the enhanced blood flow increases microvessel hematocrit, which also supports increased oxygen delivery to the active muscles (Figure 10).

How do you increase oxygen flow to muscles?

How is blood flow related to lung function during exercise?

The Effect of Exercise. At the transition from rest to intense exercise, cardiac output, and therefore pulmonary blood flow, increases by around 10 12-fold. Pulmonary vascular pressures also increase both as a result of the increased blood flow and the increases in blood viscosity caused by splenic contraction.

How is blood flow redistributed during exercise?

Redistribution of blood flow During exercise, the cardiovascular system redistributes the blood so that more of it goes to the working muscles and less of it goes to other body organs such as the digestive system. This redirection of blood flow is caused by a mechanism (or process) called the vascular shunt mechanism.

How does the body release heat during exercise?

The heat in exercising muscle causes blood vessels in the skin to dilate, increasing the blood flow to the skin. The large surface area of the skin allows all the excess heat to be lost to the surrounding air. The hypothalamus in the brain is the body’s thermostat, and receptors carry it the message of excess heat.

What is the reason for the increase in the body temperature during exercise?

This is because only approximately 20% of the energy produced in contracting muscles is used for muscle contraction; the remaining 80% is converted to heat energy, and therefore exercise causes an increase in muscle temperature. The heat is distributed to the body by the circulation and increases body temperatures.
