  1. Chap 18 – Blood Vessels Continued Learning Objectives continued Name and give the location of the major arteries and veins in the systemic circulation. Homework: Finish reading Chap 18. Learn the blood vessels of the body as outlined in this lecture.

  2. Predict The heart is said to be a “double pump”. What are your thoughts on why it has been given this designation?

  3. 2 Main Circulations in the Body • Pulmonary (heart to ______) Functions to bring blood into close contact with the ______ (air sacs of the lungs) so that gases can be exchanged.

  4. Gas Exchange Between Alveoli and Capillary

  5. Circulation of the Body 2. Systemic (blood to all the rest of the body)

  6. Major Arteries of the Systemic Circulatory System(Starting with Aorta - Upper Body) Aorta Ascending Aorta >right and left coronary arteries • Aortic Arch (3 Branches): • Brachiocephalic trunk > R. common carotid > R. Subclavian • L. common carotid > L. external carotid > L. internal carotid • L. Subclavian > L. vertebral L. axillary

  7. Major Arteries – Upper Body NOTE: Practice Labeling with Mrs. Lanoue on your blank diagram - Roman Numeral I. Arteries of Upper Body

  8. Lower Body continued Descending aorta > visceral and parietal branches (upper chest above diaphragm) > Abdominal aorta (below diaphragm) > visceral and parietal branches above diaphragm (stomach & lower abdominal areas) > R. Iliac & L. Iliac > Femoral arteries > to lower limbs

  9. Major Arteries - Lower Body

  10. Arteries – Upper Limbs

  11. Major Arteries of the Systemic SystemLabel your practice diagram, pg. 657

  12. Head and Neck Arteries These main arteries supply the head & neck: - common carotids - 3 branches from each subclavian artery: a) vertebral arteries b) thyrocervical trunks c) costocervical trunks

  13. Head and Neck Arteries continued Label your diagram.

  14. Major Veins – Upper Body

  15. Major Veins – Lower Body

  16. Major Veins of the BodyPage 669Label your diagram.
