Aim: How is circulation in vertebrates accomplished? 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 Friday
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 178:45 AM
Open Closed. Blood like fluid
hemolymph in contact
with organs. Hemolymph not invessels all the time
* Slower Flow
No hemoglobin in
hemolymph
Insects and mollusks
Require a Pumpingheart
both circulate
nutrients and
. Waste
Fluid is blood
with hemoglobin
Blood always in vessels
Rapid flow
blood is not in contact
Diffusion is between
capillaries and interstitial
fluidfound in vertebrates and
worms
/
with organs

• The job of the circulatory system is to transport substances to and out of the cells throughout the body.
It delivers:
Oxygen
nutrients
Hormones
it picks up:
CO2 and
Cellular waste

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.
Blood flow from capillaries to Veins

Aim: compare and contrast pulmonary circulation and systemic circulation
Hw: Answer questions hand out practice labeling blank heart diagram. Quiz tomorrow
1. Go over hw. general description of 2 pathways (systemic and pulmonary)
2. Anatomy of the heart
3. Complete description of pathway blood follows in each circulation
Apr 129:06 AM
Pulmonary circulation:
Loop in which blood travels from the heart to the lungs and back to the heart.
Systemic circulation: The pathway that blood follows from the heart to cells of tissues and back to the heart.
