Circulation Flashcards
Describe Pulmonary Circulation.
Pulmonary Circulation involves the heart and lungs. Deoxygenated blood is pumped from the right side of the heart to the lungs where it receives oxygen and gives up carbon dioxide by diffusion. The blood then moves from the lungs to the left side of the heart.
Describe Systemic Circulation.
Systemic Circulation involves the heart and all other parts of the body excepting the lungs. The oxygenated blood leaves the left side of the heart and goes to the body’s cells, where it becomes deoxygenated. This deoxygenated blood is then sent back to the right side of the heart.
Why is the heart called a double pump?
Your heart is a single organ, but it acts as a double pump. The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. It then delivers oxygen-rich blood back to your heart. The second pump delivers oxygen-rich blood to every part of your body. Blood needing more oxygen is sent back to the heart to begin the cycle again. Therefore the heart is considered a double pump as blood passes through it twice in one complete journey around the body.
What separates oxygenated and deoxygenated blood in the heart.
