Final answer:
Perfusion is the process by which the cardiovascular system supplies oxygenated blood to tissues and removes waste, and the definition provided is true.
Step-by-step explanation:
The definition of perfusion provided in the question, which states it is the ability of the cardiovascular system to supply tissues with adequate oxygenated blood to meet their functional demands at the time and to effectively remove metabolic waste products, is true. Perfusion is critical for maintaining tissue health and ensuring that metabolism functions efficiently throughout the body. The cardiovascular system, consisting of the heart, blood vessels, and blood, carries oxygen-rich blood away from the heart to the body (systemic circulation) and returns oxygen-poor blood back to the heart. Effective perfusion ensures that tissues receive the necessary oxygen and nutrients and can rid themselves of carbon dioxide and waste products.
