Arterien der Niere

This video tutorial provides an in-depth look at the anatomy and blood supply of the kidneys. It covers the renal artery and its branches, including the anterior and posterior rami, and the segmental arteries. The tutorial explains the interlobar and arched arteries, highlighting their roles in supplying blood to different kidney regions. It concludes with a discussion on end arteries and the implications of vascular occlusion.

What is one of the main functions of the kidneys?

• Synthesis of vitamin D

• Regulation of body temperature

• Excretion of excess fluid and electrolytes

• Production of red blood cells

From which major artery does the renal artery branch off?

• Femoral artery

• Abdominal aorta

• Carotid artery

• Thoracic aorta

Which renal artery is typically positioned slightly higher?

• Left renal artery

• Right renal artery

• Both are at the same level

• Neither, they vary greatly

How many segmental arteries does the anterior ramus give off?

• Three

• Five

• Two

• Four

Which segmental artery supplies the upper segment of the kidney?

• Inferior segmental artery

• Posterior segmental artery

• Superior segmental artery

• Anterior inferior segmental artery

What is the primary function of the posterior ramus?

• Supply the renal cortex

• Supply the renal pelvis

• Supply the posterior segment of the kidney

• Supply the anterior segment of the kidney

What do the interlobar arteries supply?

• Renal pyramids

• Renal pelvis

• Renal cortex

• Renal lobes

What is the role of the arcuate arteries?

• Supply the renal pyramids

• Supply the renal medulla

• Supply the renal cortex

• Supply the renal pelvis

What is a characteristic of end arteries in the kidneys?

• They supply the renal pelvis

• They do not form collateral circulation

• They form collateral circulation

• They are part of the venous system

What happens if there is a vascular occlusion in a kidney artery?

• The tissue is unaffected

• The tissue receives blood from collateral arteries

• The tissue dies due to lack of blood supply

• The tissue regenerates new arteries
