What do the coronary arteries primarily supply to the heart tissue?

• A. Blood with carbon dioxide.
• B. Oxygen and nutrients.
• C. Waste products for removal.
• D. Only glucose without oxygen.

Answer: (B)

The coronary arteries are crucial for supplying oxygen-rich blood and essential nutrients to the heart muscle itself. This supply is vital for maintaining the heart’s ability to pump effectively and sustain its high energy demands. The heart requires a continuous flow of oxygen and nutrients to function, as it performs the work of pumping blood throughout the body. If the heart tissue does not receive enough oxygen, it can lead to ischemia, which can result in chest pain or a heart attack. This highlights the importance of the coronary arteries in delivering the necessary components that support heart health, enabling it to operate efficiently. Therefore, the primary function of these arteries is to provide blood that is rich in oxygen and nutrients, making the second choice the correct answer in this context.
