3. Cardiovascular System:
• Cardiovascular system include Heart and Blood
vessels
• Heart:
Pumps the blood
• Blood Vessels:
Carries the blood to all parts of the body.

4. The Heart
• Location
• Thorax between the lungs
• Pointed apex directed toward left hip
• From 2nd Rib to 6th Rib
• About the size of your fist

6. • The peripheral vascular system consists of the veins and
arteries not in the chest or the abdomen that in the arm,
hands, legs and feet.
• The peripheral arteries supply the oxygenated blood to the
body.
• The peripheral veins lead deoxygenated blood from the
capillaries in the back to the heart.
Peripheral circulation:

7. FUNCTIONS:
• There are following functions of peripheral circulation:
• Supplies blood to all parts of the body except the lungs
• Exchange nutrients, waste products, and gases with
tissues
• Help to regulate body pressure
• Direct blood flow to tissues

8. Working of circulatory system
• The blood circulatory system(cardiovascular system)delivers
the nutrients and oxygen to all cells in the body.
• It consists of the heart and the blood vessels running through the
entire body.
• The arteries carry blood away from the heart the veins carry
back to the heart.

9. Types of the circulation:
• Pulmonary circulation
• Pulmonary circulation moves blood between heart and lungs.
• Systematic circulation
• It transport oxygenated blood towards the body.

10. The passage of the blood
from the right side of the
heart through arteries to the
lungs where it picks up
oxygen and is return to the
left side of the heart by
veins.
Pulmonary Circulation

11. • The pulmonary circulation is the portion of the circulatory
system which carries deoxygenated blood away from the right
ventricle of the heart ,to the lungs , and returns oxygenated
blood to the left atrium and ventricle of the heart

12. SYSTEMATIC
CIRCULATION:

13. The systematic circulation is
the portion of the
cardiovascular system which
carry the oxygenated blood
away from the heart through the
aorta from the left ventricle
where blood has been deposit
from the pulmonary circulation,
to the rest of the body and
return oxygenated blood back
to the heart.

14. BLOOD VESSELS:
• Blood vessels function to transport blood throughout
the body.
• The most important types are
• Arteries
• Capillaries
• Veins

15. ARTERIES:
• Arteries carry oxygenated blood away from the heart to the
tissues, except for pulmonary arteries, which carry blood to
the lungs for oxygenation
•VEINS:
• They are responsible for returning deoxygenated blood back to
the heart after arteries carry blood out. The vena cava is the
largest vein in the body.

16. CAPILLARIES:
• Bring nutrients and oxygen to tissues and remove waste
products

17. LOCALCONTROLE OF BLOOD FLOW
• Blood flow can increase 7-8 times as a result of vasodilation of
met arterioles and precapillary sphincter in response to
increased rate of metabolism.
• Vasomotion:
• periodic relaxation and relaxation of precapillary sphincters.
• Long term local control:
• Capillaries become more dense in region that regularly has
increased metabolic rate.

18. Nervous control of the blood vessel
• Most blood vessel in the body do not have parasympathetic
innovation .The overall effect of sympathetic activation is to
increase cardiac output, systemic vascular resistance (both
arteries, veins), arterial blood pressure.
• The sympathetic nervous system innervates blood vessel.
• The lymphatic nerves innervate the tunica media.
• The effector cells in the tunica media or smooth muscle cells.

19. Regulation of arterial pressure:
• The kidney play a dominant role in long term regulation of
arterial blood pressure by excreting variable amount of water
and salts.
• In addition, kidney contribute in short term regulation of arterial
blood pressure by secreting vasoactive factors or substances,
such as renin that lead to formation of vasoactive formation.
