Pulmonary Circuit and Systemic Circuit Flashcards
What happens in the pulmonary circuit?
The pulmonary circuit carries deoxygenated blood to the lungs and carries oxygenated blood back to the heart
What happens in the systemic circuit?
The systemic circuit carries oxygenated blood to the body and deoxygenated blood back to the heart
Remember : Pulmonary starts with deoxygenated blood to the lungs
*both end up going back to the heart
Remember: Systemic starts with oxygenated blood to the body
*both end up going back to the heart
What is the definition of Pulmonary circuit?
The circulation of blood through the pulmonary artery to the lungs and the pulmonary vein back to the heart
What is the definition of Systemic circuit?
The circulation of blood through the aorta to the body and vena cava back to the heart
What happens in the capillaries?
Gas exchange occurs at the capillaries
Describe the cycle of the pulmonary circuit:
At the pulmonary circuit, deoxygenated blood pumps through the pulmonary artery to the lungs and oxygenated blood is pumped back to the heart by the pulmonary vein
Describe the cycle of the systemic circuit:
At the systemic circuit, oxygenated blood is pumped through the aorta to the body and deoxygenated blood is pumped back to the heart by the vena cava
Why is it important for an aerobic athlete to have an efficient cardiovascular system?
The more efficient the cardiovascular system, the greater the capacity you have to transport oxygen to the working muscles and also the greater capacity you have to remove waste products such as lactic acid and carbon dioxide. This is essential to maximise energy production and delay the onset of fatigue, allowing you to perform for longer.
