VEINS IN THE CAT AND HUMAN MODELS
NOTE: There are three types of jugular veins and three types of iliac veins in the cat.
Do not just write “jugular” or “iliac” on the test!
NOTE: There are three types of carotid arteries and three types of iliac
arteries. Do not just write “carotid” or “iliac” on the test!
NOTE: There are three types of aorta: aortic arch, thoracic aorta, and
abdominal aorta. Do not just write “aorta” on the test!
