What are the 4 main arteries of the heart?

What are the 3 main heart arteries?
What are the two major coronary arteries?
- Right coronary artery supplies the right atrium and right ventricle with blood.
- Left main coronary artery branches into the circumflex artery and the left anterior descending artery.
What’s the strongest organ in your body?
The heart has the ability to beat over 3 billion times in a person’s life. The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What is the hardest stone on earth?

Which is the smallest organ in the human body?
pineal gland
Can you live with a blocked artery?
Blocked tunnels aren’t good for traffic flow, and blocked arteries aren’t good for your heart. In cardiology, the boulder is called a Chronic Total Occlusion (CTO). It means the artery is completely blocked. This occurs in 15 percent to 20 percent of patients who have heart disease.
How many arteries does a human heart have?
The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.
