Final answer:
Blood doping is associated with the circulatory system, which is responsible for transporting oxygen, nutrients, hormones, and waste materials and is vital for maintaining homeostasis.
Step-by-step explanation:
The system involved in helping the process of blood doping is the circulatory system, also known as the cardiovascular system. Blood doping enhances an individual's athletic performance by artificially increasing the blood's ability to transport oxygen to muscles, thus improving endurance and recovery. The cardiovascular system is crucial for transporting oxygen from the lungs to the rest of the body and returning carbon dioxide to the lungs for exhalation, a collaborative effort with the respiratory system for maintaining homeostasis.
The circulatory system is responsible for transporting not just oxygen but also nutrients from the digestive system, hormones from the endocrine system, and waste materials from cells throughout the body. The heart, blood vessels, and blood are the main components of this system. During blood doping, additional red blood cells, either from the same individual or a donor, are introduced into the body to increase the blood's oxygen-carrying capacity.
