WebThe hole between the top two heart chambers (right and left atrium) is called a patent foramen ovale (PFO). This hole allows the oxygen rich blood to go from the right atrium to left atrium and then to the left ventricle and out the aorta. As a result the blood with the most oxygen gets to the brain. WebIntroduction During physical activity, the circulatory and respiratory systems play critical roles in the delivery of oxygen and nutrients to cells as well as the removal of metabolic waste products such as carbon dioxide. Acute adaptation is the reaction of these systems during and quickly after a single exercise session and refers to the immediate changes …
