Systemic circuit pump
34
True or False. Blood flows from the right side of the heart to the lungs and back to the left side of the heart.
True.
35
True or False. Right side - pulmonary trunk - lungs - pulmonary arteries - pulmonary veins - heart - organs

36
What type of circulation is this? OR blood to left side to aorta to systemic arteries to body tissues to systemic veins to right atrium to vena cava
Systemic Circulation
37
Why does left ventricle has thicker walls?
Because it pumps blood to the body through the systemic circuit.
