A double circulatory system means blood passes through the heart twice per circuit, allowing the left ventricle to generate high pressure for systemic circulation and ensuring low pressure upon blood entry into lung capillaries.
- blood passes through the heart twice per circuit - so that cardiac muscle in left ventricle wall can generate high pressure with strong contraction - low blood pressure as blood enters lung capillaries
