Question
Chapter 18, Problem 1RQ
Summary Introduction
To determine:
The false statement about erythrocytes.
Introduction:
The most abundant cells in the blood are known as erythrocytes, which are also termed as red blood cells. These cells are mainly involved in the transportation of oxygen to various tissues of the body. These cells are produced within the bone marrow through the process of hematopoiesis.

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. Explain how the endocrine system contributes to the homeostasis of blood oxygen levels.arrow_forward
- 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_forwardWhich of the following might trigger erythropoiesis? a. decreased tissue demand for oxygen. b. Blood oxygen levels fall below normal. c. moving to a lower altitude. d. an increased number of RBCs.arrow_forwardWhich of the following would lead to increased erythropoiesis? Select one: a. Increased erythropoietin levels b. Increased blood pressure c. Increased environmental O2 levels d. Increased blood pH e. Increased CO2 levelsarrow_forward
- What type(s) of blood cells is (are) described with each statement? Choose from erythrocytes, leukocytes, or platelets. a. This type of blood cell has no nucleus. b. This type of blood cell survives in the bloodstream for the longest period of time. c. This type of blood cell is a key element in the immune system. d. This type of blood cell carries hemoglobin. e. This type of blood cell contains the machinery needed for clot formation.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_forwardThe term "hematopoiesis" refers to: Select one: a. the mechanisms that prevent blood loss O b. the process of blood cell formation O c. the rupture of red blood cells O d. a disease in which there is insufficient blood cell productionarrow_forward
