Cat Vascular System Anatomy

The video tutorial explores the cat's vascular system, focusing on the arterial and venous structures. It begins with the heart and the left coronary artery, then moves to the pulmonary trunk and aorta, highlighting the differences between cats and humans. The aortic arch and its branches, including the brachiocephalic and subclavian arteries, are detailed. The video also covers the venous system, noting the differences in jugular veins between species. Finally, it examines the leg vessels, including the femoral artery and the great saphenous vein, which is used in bypass surgeries.

What is the primary function of the left coronary artery in cats?

• To supply blood to the pulmonary trunk

• To supply blood to the left atrium

• To supply blood to the left ventricle

• To supply blood to the right atrium

What is the role of the pulmonary trunk in the cat's vascular system?

• To carry oxygenated blood to the heart

• To carry deoxygenated blood to the heart

• To carry deoxygenated blood to the lungs

• To carry oxygenated blood to the lungs

Which part of the aorta is referred to as the 'candy cane' in the cat's vascular system?

• Ascending aorta

• Thoracic aorta

• Aortic arch

• Descending aorta

How many branches come off the aortic arch in cats?

• Two

• One

• Four

• Three

Which artery is the first branch off the brachiocephalic artery in cats?

• Left common carotid artery

• Right common carotid artery

• Right subclavian artery

• Left subclavian artery

What is the main difference between the jugular veins in cats and humans?

• Cats have a larger internal jugular vein

• Cats have a larger external jugular vein

• Humans have no external jugular vein

• Humans have no internal jugular vein

What is the function of the azygos vein in the cat's vascular system?

• To drain blood from the head

• To drain blood from the posterior chest wall

• To supply blood to the heart

• To supply blood to the lungs

Which vein is used as a source for bypass material in coronary bypass surgery?

• Brachial vein

• Great saphenous vein

• Femoral vein

• Axillary vein

Where does the femoral artery transition into the popliteal artery in cats?

• At the knee joint

• At the hip joint

• At the ankle joint

• At the inguinal ligament

What is the significance of the great saphenous vein in both cats and humans?

• It is the longest vein in the body

• It is the shortest vein in the body

• It is the most superficial vein in the body

• It is the deepest vein in the body
