Learning Objectives continued
1. 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.
Predict
The heart is said to be a “double pump”. What are your thoughts on why it has been given this designation?
2 Main Circulations in the Body1. Pulmonary
(heart to ______)
Functions to
bring blood into close contact with the ______ (air sacs of the lungs) so that gases can be exchanged.
Major Arteries of the Systemic Circulatory System(Starting with Aorta - Upper Body)
Aorta
Ascending Aorta >right and left coronary arteries
Aortic Arch (3 Branches):
1. Brachiocephalic trunk > R. common carotid > R. Subclavian
2. L. common carotid > L. external carotid > L. internal carotid
3. L. Subclavian > L. vertebral L. axillary
Major Arteries – Upper Body
NOTE: Practice Labeling with Mrs. Lanoue on your blank diagram - Roman Numeral I. Arteries of Upper Body
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
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
