Course Grading If you receive at least 92% (37 out of 40), you may substitute your score in place of taking the post quiz and attending seminar. If you receive less than 92%, your score will not be used to calculate your grade and you must take the post quiz and attend seminar.
Late Assignment Policy LATE POLICY TOP Late work will not be accepted unless there are clear and compelling extenuatingcircumstances. If you have extenuating circumstances that prevent you from completing course assignments/exams you must contact your instructor immediately—prior to the assignment/exam/quiz due-date unless prevented from doing so by emergency circumstances. Examples of extenuating circumstances are serious personal and/or family illness/hospitalization, death in the family, weather-related evacuation/emergencies, work emergencies, and issues related to active military assignment. Personal computer/software/internet connectivity issues and course blocks are not considered extenuating circumstances. Granting of late-work submission due to extenuating circumstances is at the discretion of the instructor and will require documentation for verification of extenuating circumstances. If late work submission is granted, the instructor will establish new due-dates and requirements without loss of course points. Incompletes Incompletes provide students with limited additional time to complete coursework after the term’s end. To be considered for an incomplete, you should have completed approximately 75% of the coursework. Please see the Kaplan University catalog for further information. Whether or not to grant an incomplete is your instructor’s decision. The deadline for requesting an incomplete for the 1101C term is March 7, 2011. Incomplete work is due March 25, 2011.

Project Information Let’s go on a “Fantastic Voyage!” Imagine that you are a video reporter piloting a mini-sub that has been put through a miniaturization process making you and the sub only 8 microns long! (Ever see the movie “Inner Space”?) You have been injected into the femoral vein of a healthy female. The alert just came out that a bacterium is invading the lower lobe of the right lung!! You are to pilot your sub to the site of the “invasion” and do a live report on what you see. Your “Fantastic Voyage!” is continuing. You are still a video reporter piloting a mini-sub that has been put through a miniaturization process making you and the sub only 8 microns long. This time, you have been swallowed by a 55 year old man eating a hamburger, french fries and a root beer.
Plagarism Policy The policy is published in the Kaplan University Catalog/addendum.http://epmedia.ecollege.com/media/kaplan/store/academictech/faculty/Plagiarism/Plagiarism%20Policy,%20Appeals%20Policy%20and%20Plagiarism%20Procedures%202008.pdf Kaplan University considers academic honesty to be one of its highest values. Students are expected to be the sole authors of their work. Use of another person’s work or ideas must be accompanied by specific citations and references. Though not a comprehensive or exhaustive list, the following are some examples of dishonesty or unethical and unprofessional behavior:
Plagarism Policy • Plagiarism: Using another person’s words, ideas, or results without giving proper credit to that person; giving the impression that it is the student’s own work. • Any form of cheating on examinations. • Altering academic or clinical records. • Falsifying information for any assignments. • Submitting an assignment(s) that was partially or wholly completed by another student. • Copying work or written text from a student, the Internet, or any document without giving due credit to the source of the information. • Submitting an assignment(s) for more than one class without enhancing and refining the assignment, and without first receiving instructor permission. In cases where previous assignments are allowed to be submitted for another class, it is the responsibility of the student to enhance the assignment with additional research and to also submit the original assignment for comparison purposes. • Assisting another student with reasonable knowledge that the other student intends to commit any act of academic dishonesty. This offense would include, but would not be limited to providing an assignment to another student to submit as his/her own work or allowing another student to copy answers to any test, examination or assignment
Plagarism Policy Kaplan University subscribes to a third-party plagiarism detection service, and reserves the right to check all student work to verify that it meets the guidelines of this policy. Academic dishonesty is a serious offense and may result in the following sanctions: 1st offense: Failure of the assignment in which the action occurred. 2nd offense: Failure of the class in which the action occurred. 3rd offense: Expulsion or permanent dismissal from the University.
Unit 1: Blood
Blood Composition • Blood plasma • blood minus its cells • composition—water containing many dissolved substances (for example, foods, salts, and hormones) • amount of blood—varies with a person’s size and sex; average is about 4 to 6 L (about 7% to 9% of body weight) What is the difference between blood plasma and blood serum?
Blood Composition • Formed elements • RBCs (erythrocytes) • WBCs (leukocytes) • Granular leukocytes:Neutrophils, eosinophils, and basophils • Nongranular leukocytes: Lymphocytes and monocytes • Platelets or thrombocytes
Blood Composition • Formed elements • Numbers • RBCs: 4.5 to 5 million per mm3 of blood • WBCs: 5,000 to 10,000 per mm3 of blood • Platelets: 300,000 per mm3 of blood • Formation • Red bone marrow, or myeloid tissue, forms all blood cells except some lymphocytes and monocytes, which are formed by lymphatic tissue in the lymph nodes, thymus, and spleen Where is red bone marrow produced?
Blood Composition • RBCs • Structure • Disk-shaped, without nuclei • Anemia: Inability of blood to carry adequate oxygen to tissue; often caused by • Inadequate RBC numbers • Deficiency of hemoglobin or iron • Pernicious anemia: Deficiency of the intrinsic factor What are some of the functions of RBCs?
Blood Composition • RBCs • Hematocrit: Medical test in which a centrifuge is used to separate whole blood into formed elements and liquid fraction • Buffy coat is WBC and platelet fraction • Normal RBC level is about 45% • Polycythemia: Abnormally high RBC count What happens to RBCs during the hematocrit procedure?
Blood Composition What is sickle cell anemia, and how does it affect the body?
Blood Composition • WBCs • Neutrophils and monocytes carry out phagocytosis • Lymphocytes produce antibodies (B-lymphocytes) or directly attack foreign cells (T-lymphocytes) • Eosinophils protect against parasitic irritants that cause allergies • Basophils produce heparin, which inhibits clotting What is phagocytosis?
Blood Clotting • Platelets and blood clotting • Platelets play an essential role in blood clotting • Blood clot formation • Clotting factors released at the injury site produce prothrombin activator • Prothrombin activator and calcium convert prothrombin to thrombin • Thrombin triggers formation of fibrin, which traps RBC to form a clot When does clotting become dangerous?
Blood Types • ABO system • Type A blood: Type A self-antigens in RBCs; anti-B-type antibodies in plasma • Type B blood: Type B self-antigens in RBCs; anti-A-type antibodies in plasma • Type AB blood: Type A and type B self-antigens in RBCs; no anti-A or anti-B antibodies in plasma • Type O blood: No type A or type B self-antigens in RBCs; both anti-A and anti-B antibodies in plasma What are antigens and antibodies, and how do they relate to each other?
Blood Types • Rh system • Rh-positive blood • Rh factor antigen present in RBCs • Rh-negative blood • No Rh factor present in RBCs • No anti-Rh antibodies present naturally in plasma • Anti-Rh antibodies appear in the plasma of Rh-negative people if Rh-positive RBCs have been introduced into their bodies Where did the term “Rh” come from?
Erythroblastosisfetalis: May occur when Rh-negative mother carries a second Rh-positive fetus; caused by mother’s Rh antibodies reacting with baby’s Rh-positive cells
