The accompanying graph relates to the abundance of ocean life (productivity) in a polar region of the Northern Hemisphere. Brings deoxygenated blood back to the Right Atrium. This is important as the muscles require oxygen and nutrients for muscle contraction, whilst the skin requires blood flow to cool down through sweating. Cardiovascular drift (CVD, CV drift) is the phenomenon where some cardiovascular responses begin a time-dependent change, or "drift", after around 5-10 minutes of exercise in a warm or neutral environment 32 C (90 F)+ without an increase in workload.

As glycogen is stored alongside water, when it is used for muscle contraction, water loss occurs. Compared to static or dynamic resistance exercise, aerobic exercise demands an increase in energy and therefore an increase in oxygen (hence aerobic exercise). The site is secure. Circulation , 122, S706 - S719. The decrease in blood plasma results in a decrease in venous return, the volume of blood returning to the heart, and therefore a decrease in stroke volume, the volume of blood ejected from the left ventricle per beat.
