Cardiovascular physiology
The Need for a Circulatory System
3
Lungs ( gas exchange)
Gastrointestinal tract (absorption and elimination)
Kidneys (balance of water and electrolytes)
Skin (exchange of water and electrolytes and exchange of
heat)
The Need for a Circulatory System
4
Lymphatic Circulation is associated with both
ones
High pressure system
Lowpressure system
The Arrangement of The cardiovascular system
The Arrangement of The cardiovascular system
6
Distribution of blood to the
different regions of the body
determined by:
1. Cardiac output
2.Contractile state of the
arterioles
The Arrangement of The cardiovascular system
7
Other Function of Cardiovascular System
Heart
Secretion of hormones (atrial natriuretic peptide)
Regulation of the release of other hormones (Like ADH)
Vessels
Secretion of hormones (Nitric oxide [NO], Enditheilin-1[ET-1]
and prostacyclin[PGI2])
Inflammatory responses

The Development of Cardiac and Vascular Function
Adaptation:
◦ During exercises
◦ During change position
Neuronal Reflexes are rapid, short-acting mechanism
Hormonal Reflexes are slow, long-acting mechanism
