Question
Chapter 23, Problem 2SQ
Summary Introduction
To examine: Whether the statement, “all arteries carry oxygen-rich blood, while all veins carry oxygen-poor blood,” is true or false.
Introduction:
The circulatory system consists of a major organ which is the heart and the blood vessels that include arteries, veins, and capillaries. Blood vessels allow the efficient transport of blood from heart to all body parts and then back.

- Several years ago, the deaths of several airline travelers led to the warning about “economic-class syndrome.” The idea is that economic-class passengers do not have as much leg room as passengers in more expensive seats, so they are more likely to sit essentially motionless for long periods of flights-conditions that may allow blood to pool and clots to form in the legs. This condition is called deep-vein thrombosis, or DVT. Given what you know about blood flow in the veins, explain why periodically getting up and moving around in a plane’s cabin during a long flight may lower the risk that a cloth will form.arrow_forwardA pharmaceutical company develops an artificial red blood cell that is very effective at transporting oxygen but unable to transport carbon dioxide. Explain what would happen in the blood vessels if this substance were used in a blood transfusion. How would this affect the recipient (Assume the transfusion has no effect on the level of plasma in the blood)?arrow_forwardLow doses of aspirin are commonly used to reduce the risk of arterial thrombosis in patients who have suffered myocardial infarction. Which one of the following steps in hemostasis is inhibited by aspirin? Aggregation of platelets| Adhesion of platelets to collagen Production of tissue factor Synthesis of von Willebrand factor Synthesis of antithrombin III|arrow_forward

Which of the following functions are most likely affected by anemia? The ability to defend the body against bacteria Transportation of carbon dioxide The ability to stop bleeding by forming blood clots Transportation of hormones throughout the bodyarrow_forwardThe 3 phases (in general) of blood clotting are: vascular phase, platelet phase & coagulation phase. In basic terms, what occurs at each phase? What are the steps of clot retraction (dissolution)?arrow_forward
- The exact cause of blood clotting in the left atrium of the heart during atrial fibrillation (AF) is not known. In part it might be due to blood stasis (not moving) or it may result in combination with endothelial cells damage. (A) What are the potential mechanisms that might drive clotting and what markers might you look for in the blood to predict potential risk? (B) Other than treating the arrhythmia, what other pharmacological intervention might be provided to AF sufferers?arrow_forwardBlood clotting is one of nature's most elegant creations, but it sometimes goes awry. Use your knowledge of different types of blood cells and the chemical aspects of the clotting process to answer the following: 1. After getting his blood cell count, Josh was informed that his platelet count was low. What is a typical platelet count? How would Josh's low platelet count impact his hemostasis after getting a cut on his forearm? (Be very specific) 2. Briefly explain the different roles of the three stages of the intrinsic blood clotting pathway 3. Explain how any event that prevents plasminogen from becoming fully activated would lead to a thromboembolic disorder. Identify all the chemicals that directly activate plasminogen. 4. Identify the two most common types of the genetic disorder called hemophilia. Explain how each of two types of hemophilia result in impaired hemostasis. 5.

- Why are there so many more erythrocytes than leukocytes in both healthy and sick individuals?arrow_forwardWhat do you mean by erythroblast? Briefly explain.arrow_forwardThe production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. (i) Is this a positive or negative feedback loop and why? (ii) For the above feedback loop, what would be the: 1. signal detected by the sensor: 2. effector: 3. response: 4. final result:arrow_forward
