Final answer:
Cardiovascular disease compromises the function of blood related to the transport of oxygen, which is essential for the delivery of nutrients to, and the removal of wastes from, body cells. The option (C) is correct.
Step-by-step explanation:
The function of blood that cardiovascular disease compromises is oxygen transport. Cardiovascular diseases can impair the circulation of blood, thus affecting the primary role of the cardiovascular system, which includes transporting oxygen and nutrients to body cells and removing waste materials.
Any reduction in blood vessel functioning due to cardiovascular disease can lead to reduced oxygen transport to tissues, impaired metabolism, and the potential for tissue injury. In addition to oxygen and nutrient distribution, blood also plays a critical role in defense, distribution of heat, and maintenance of homeostasis. Therefore, option (C) is correct.
