Arterial System

Arterial-system
Arterial System
The heart pumps oxygenated blood into artery i.e. arota. All arteries carry oxygenated blood except pulmonary artery. Arota is primary artery, collect oxygenated blood from left ventricle and arota divided into branches, these branches further subdivided. The finally end of arteries in capillary form. 

Artery has tube like structure. 

The wall of artery is consists with three membrane-
 
Tunica adventitia – Outer fibrous membrane.

Tunica media – Middle muscle membrane.

Tunica intima – Inner serous membrane.

Arota consists of following primary branches:
  • Ascending Arota
  • Arch of Arota
  • Thoracic Arota
  • Abdominal Arota
