What organs are involved in coronary circulation?

Coronary Circulation The heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation.

What is the pathway of coronary circulation?

In the human heart, two coronary arteries arise from the aorta just beyond the semilunar valves; during diastole, the increased aortic pressure above the valves forces blood into the coronary arteries and thence into the musculature of the heart.

What are the three main coronary arteries?

The coronary arteries consist of two main arteries: the right and left coronary arteries, and their two branches, the circumflex artery and the left anterior descending artery. What are the different coronary arteries? The two main coronary arteries are the left and right coronary arteries.

What are the two main parts of the circulatory system?

Parts of the Cardiovascular System

  • Blood. Blood is the fluid that carries the oxygen and nutrients vital to the function of the body, as well as the waste that needs to be removed.
  • Blood Vessels.
  • Heart.

What are the major organs of the human body Important?

Vital organs

  • Brain. The brain is the body’s control center.
  • Heart. The heart is the most important organ of the circulatory system, which helps deliver blood to the body.
  • Lungs. The lungs work with the heart to oxygenate blood.
  • Liver. The liver is the most important organ of the metabolic system.
  • Kidneys.

What are the two main organs of the cardiorespiratory system?

The cardiorespiratory system consists of the heart and blood vessels, which work with the respiratory system (the lungs and airways).

Which organ is supplied with blood via the coronary arteries quizlet?

Describe the Coronary Artery Blood Supply of the Heart. Main coronary arteries lie on the SURFACE of the heart. Smaller arteries then PENETRATE the surface INTO the Cardiac Muscle Mass.

What is the main vein that drains coronary circulation?

The great cardiac vein (GCV) runs in the anterior interventricular groove and drains the anterior aspect of the heart where it is the venous complement of the left anterior descending artery. It is the main tributary of the coronary sinus.

What are two main parts of the circulatory system?

What Are the Parts of the Circulatory System? Two pathways come from the heart: The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.
