Unit 4A Worksheet

1) The heart circulates oxygenated blood to the systemic ______via the aorta but this does not include the blood which supplies the______. The heart supplies the lungs via the pulmonary______, which deliver ______blood to the lungs to release carbon dioxide (CO2) and pick up ______(O2). This ______-rich blood goes back to the heart via the pulmonary______.

2) Blood circulates away from the heart via______, which carry blood ______from the______. This blood can be deoxygenated at times and also oxygen-______at other times. The main point is that ______carries blood ______from the______.

3) Blood circulates back to the heart via______, which brings blood back to the______. This blood can be ______-rich at times and also ______at other times. The main point is that ______bring blood ______to the______.

4) Oxygen-______blood which can be found in systemic ______and pulmonary ______is more of a ______red due to the ______oxygen content. While ______blood found in systemic ______and pulmonary ______is more of a ______red due to ______oxygen content.

5) In the illustrations of systemic circulatory vessels, ______and arterioles are colored ______indicating their low / highoxygen content of the blood. The capillary ______are colored red to purple to ______indicating the loss of their ______content and increasing ______Dioxide contend as they facilitate ______exchange. The ______and venulesare colored blue in the systemic circulatory illustrations due to their ______oxygen and ______carbon dioxide content. But in actuality the blood within these vessels is always______.

6) In the illustrations of the pulmonary circulatory system the pulmonary ______are colored blue as they carry deoxygenate blood ______from the heart to the lungs where the capillary network is illustrated first being blue then purple then red due to the gas exchange they facilitate as the capillaries first get rid of the carbon dioxide and take in ______and bring this ______-rich blood ______to the heart in pulmonary ______which are colored______. But in actuality the blood within these vessels are always______.

8) The extracellular fluids include blood ______which has more ______than lymph or ______fluids which are fluids found ______red blood cells, ______blood cells and ______that are suspended in______. The ______in blood plasma helps pull ______back into the______.
