You will use this page to get your Labs for the Chapter signed off by the Biology Learning Center staff. You need to have all of the following steps initialed by a staff member before you can be allowed to take the Chapter Exam.After you have obtained all of your sign offs for this Chapter, be sure that a BLC staff member indicates on your Lab Card that you are OK to take the Chapter Exam. Also, keep this sign off page, along with your completed lab worksheets, as proof of your lab completion. If your Lab Card indicates that you have not completed the required Labs for this Chapter, and you feel that you have, it is up to you to provide proof that you have indeed done the Labs.

The formed elements are the living blood cells. The non-living fluid matrix is called ______________________________. Spun blood separates into 3 layers. What does the buffy coat consist of? ___________________What does the reddish mass at the bottom of the tube consist of? ____________________What percent of your blood is plasma? ______________________________A normal hematocrit reading is around 45%. What does the 45% refer to? ________________________________________________________________Plasma is the liquid portion of blood and it is _____________% water. Over 100 substances are dissolved in plasma. Plasma proteins are the most abundant solutes in plasma.Most plasma proteins are produced by the __________________________________Which plasma protein contributes to the osmotic pressure of blood? ______________________Which plasma proteins are involved with healing injured blood vessels? ___________________Which plasma proteins help protect the body from pathogens? __________________________Blood must stay in the pH range of 7.35-7.45 which is slightly ________________________________The formed elements comprise about 45% of the total blood volumeThe formed elements are the WBCs, RBCs, and platelets. What is the other name for red blood cell (RBC)? _______________________________________What is the other name for white blood cell (WBC)? ________________________________________The function of RBCs is to transport __________________________ to all of the cells of the body. RBCs are biconcave discs that have no _________________________and few organelles.The main component of the red blood cell is ___________________________________Each hemoglobin molecule can bind (reversibly) to 4 oxygen molecules. Each RBC can carry 1 billion oxygen molecules. _____________________________ is a decrease in the oxygen-carrying abiltiy of the blood. This can occur due to decreased numbers of RBCs or deficient hemoglobin content. White blood cells are part of the body's immune system. Red blood cells outnumber white blood cells 1000 : 1WBCs are complete cells with _____________________________ and other organelles.

This is called ______________________________WBCs can move toward chemicals relased by damaged cells. This is called ___________________WBCs move through various tissues by amoeboid movement. Neutrophils are the most numerous of the WBCs.Neutrophils are the first to an injury site where they act as ______________________________Eosinophils increase in numbers during allergic responses and infections by parasitic worms. Basophils promote inflammation by secreting ______________________________. Lymphocytes play an important role in the immune response and kill cells containing ___________. Monocytes are the largest of the WBCs. Monocytes migrate into the tissues and become ____________________________ cleaning up bacteria, dead cells and debris. Platelets are cell fragments of multinucleate cells called megakaryoctyes. Platelets are involved with the _______________________________ process. Blood cell formation also called hematopoiesis occurs in the _____________________________________ All blood cells are derived from the common stem cell ___________________________________. The hemocytoblasts form two types of stem cell; the lymphoid stem cells and the myeloid stem cells. All of the blood cells except lymphocytes are descendants of _________________________ stem cells. Red blood cells wear out in 100–120 days. Worn out RBCs are removed by phagocytes in the ___________________ and ___________________Phagocytized RBCs are replaced by continuously by the division of __________________________ in the red bone marrow. The rate of erythrocyte production is controlled by a hormone called erythropoietin. Erythropoietin is secreted by the _________________________ in response to low oxygen levels in the blood. HemostasisHemostasis is the stoppage of blood flow in response to a damaged blood vessel. What are the 3 major phases of hemostasis? ________________________________________________________________________ ________________________________________In the end of the coagulation phase, what meshwork forms the basis of the clot? _________________What is the purpose of the vascular spasm? _____________________________________Blood normally clots within 3 to 6 minutes. A clot that develops and persists in an unbroken blood vessel is called a _________________________.Last updated: 3/21/143BIO 160: Introduction to Human Anatomy and Physiology A clot in a coronary artery is called a coronary thrombosis and can result in a myocardial infarction (heart attack). An embolus is a thrombus that breaks away from the vessel wall and floats through the bloodstream. A cerebral embolus can cause a ___________________________________ . The bleeding disorder that results from a lack of platelets is called _____________________________The hereditary bleeding disorder where clotting factors are missing is called
