- B. Amount of blood is limited
- C. Blood circulates through arteries, veins, and capillaries
- D. Blood pressure is low and irregular
Explanation
In an open circulatory system, blood pressure is generally low and irregular, as the blood is not confined to vessels and instead flows freely through the body cavity. This can limit the efficiency of oxygen and nutrient delivery to the body's tissues, as well as the removal of waste products. In contrast, a closed circulatory system maintains a higher and more consistent blood pressure, which allows for more efficient delivery of oxygen and nutrients to the body's tissues.
