Slide 1:

8/6/2011 Circulatory system Prepared and presented by: Arpan j. shah Lecturer, Atmiya college of pharmacy Vadodara , gujarat

Circulatory system:

The CVS contributes to homeostasis of other body systems by transporting and distributing blood throughout the body to deliver material such as O 2 , nutrient and hormones . This transport occurs via blood vessels , which form a closed system of tubes that carries blood away from the heart, transports it to the tissues of the body and then returns it to the heart. The five main types of blood vessels are in the blood transport. Circulatory system

Circulatory system:

Arteries : carry blood away from the heart to other organs. Arterioles : small, almost microscopic, artery that deliver blood to a capillary. Capillaries : microscopic blood vessels located between an arterioles and venules through which material are exchanged between blood and interstitial fluid. Venules : small vein that collects blood from capillaries and delivers it to a vein. Vein : blood vessel that conveys blood from tissues back to the heart. Circulatory system Function of blood vessels

Structure of blood vessels Circulatory system

Circulatory system:

With the each beat, the heart pumps blood into two closed circuits: the systemic circulation and the pulmonary circulation. Systemic circulation: It is long circuit that starts from the left ventricle, supplies the blood to all the part of the body, except the lung. Blood is finally collected into the right atrium. The systemic circulation can be described under the arterial system and the venous system . Circulatory system

Ascending aorta:

Ascending aorta About 5 cm in length, begins at aortic valve. Directed superiorly, slightly anteriorly and to the right It end at the level of the sternal angle.

Thoracic aorta:

8/6/2011 Thoracic aorta About 20 cm long. Sends off numerous small arteries, visceral branches to viscera and parietal branches to body wall structures.

Abdominal aorta:

Abdominal aorta It begins at the aortic hiatus in the diaphragm and end about the level of the 4 th lumbar vertebrae, where it divide into the right and left common iliac arteries . It gives off visceral and parietal branches.
