Aim: How does circulation in vertebrates work? what are the main circulatory organs?
Hw. Read pgs 948, 952 then compare and contrast systemic circulation to pulmonary circulation. Start studying for Quiz on circulation 1. Go over test and hw. 2.The job of the circulatory system in vertebrates. 3. organs and the job of each one.
4. compare blood vessels function and shape Apr 19­4:33 PM

• The job of the circulatory system is to transport
substances to and out of the cells throughout the body. it picks up:
It delivers: CO2 and Oxygen
nutrients
Hormones
Cellular waste
Apr 10­12:57 PM
2. Anatomy of the C. S. The main organs are:
• The Heart. It is a muscular organ that pumps blood and fluids trough an elaborate system of vessels. • Blood: liquid tissue that transports nutrients, waste and hormones. contains 3 different types of cells (Red, white, and platelets)
and plasma (water +solutes)
• Vessels Tube like structures that distribute blood through the body include: A. Veins transport blood to the heart(contain valves and carry poorly oxygenated )
B. arteries transport blood away from the heart (no valves and carry oxygenated blood ) C. capillaries narrow vessels blood flow from capillaries to venules. Capillaries allow exchange fluids between blood and interstitial fluid. Apr 19­6:11 PM

Systemic circulation: The pathway that blood follows from the heart to cells of tissues and back to the heart. It goes like this
Heart arteries capillaries venules veins heart.
Right
Left Ventricle
exchange of materials with
atrium
surrounding interstitial fluid .
Pulmonary circulation:
Loop in which blood travels from the heart to the lungs and back to the heart. Apr 19­6:19 PM
