Final answer:
It is true that good blood circulation is crucial for recovery from injury or illness because it supports healing processes and immune response. The cardiovascular system maintains systemic blood pressure above 60 for filtration and circulates blood throughout the body, which is vital to prevent conditions such as strokes.
Step-by-step explanation:
Ensuring good blood circulation throughout the body is true for recovering from an injury or illness. Good circulation is essential because it helps to deliver oxygen, nutrients, and immune cells to the site of injury or infection, facilitating healing and fighting off possible infections. Furthermore, proper circulation aids in the removal of waste products from the area. However, during inflammation, not all blood cells retreat from the site of infection; rather, immune cells are actively directed towards the site to combat pathogens.
Considering the cardiovascular system, it is important to note that it does not solely bring blood to and from the lungs, but provides a means of blood transport throughout the entire body. The statement that systemic blood pressure must stay above 60 is true, to ensure correct filtration and proper circulation of blood to the tissues. With regards to strokes, they can indeed be caused by a blood clot or a broken artery, underscoring the importance of maintaining a healthy circulatory system.
