What is the path of blood from heart to left zygomaticus muscles and back heart?

The path of blood from the heart to the left zygomaticus muscles and back to the heart is as follows:

1. Heart: The blood starts from the left ventricle of the heart.

2. Aorta: The blood is pumped out of the heart through the ascending aorta.

3. Brachiocephalic trunk: The ascending aorta branches into the brachiocephalic trunk, which gives rise to the right common carotid artery and the right subclavian artery.

4. Right common carotid artery: The right common carotid artery travels up the neck and branches into the right internal carotid artery and the right external carotid artery.

5. Right external carotid artery: The right external carotid artery supplies blood to the face and scalp. It gives off several branches, including the transverse facial artery.

6. Transverse facial artery: The transverse facial artery runs across the face and supplies blood to the zygomaticus muscles, which are responsible for raising the corners of the mouth.

7. Veins: The blood from the zygomaticus muscles drains into the facial vein, which eventually empties into the internal jugular vein.

8. Internal jugular vein: The internal jugular vein carries blood from the head and face back to the heart.

9. Superior vena cava: The internal jugular vein joins the subclavian vein to form the superior vena cava, which empties into the right atrium of the heart.

10. Right atrium: The blood flows from the superior vena cava into the right atrium of the heart.

11. Right ventricle: The blood is then pumped from the right atrium into the right ventricle.

12. Pulmonary artery: The blood is pumped out of the right ventricle through the pulmonary artery.

13. Lungs: The pulmonary artery carries the blood to the lungs, where it picks up oxygen and releases carbon dioxide.

14. Pulmonary veins: The oxygenated blood returns to the heart through the pulmonary veins, which empty into the left atrium.

15. Left atrium: The blood flows from the pulmonary veins into the left atrium of the heart.

16. Left ventricle: The blood is then pumped from the left atrium into the left ventricle.

17. Aorta: The blood is pumped out of the heart through the ascending aorta, and the cycle repeats.
