1. Unit 5 Exam Speed Review

2. Obj: Compare Components of Blood

3. BLOOD – the only fluid tissue PLASMA (55%) WHITE BLOOD CELLS & PLATELETS (Less than 1%) RED BLOOD CELLS (45%) FORMED ELEMENTS Red Blood Cells White Blood Cells Platelets

4. ComponentFunction/Info PLASMA55%, made up mostly of water, liquid part of blood WHITE BLOOD CELLS (LEUKOCYTE) Less than 1% (w/ platelets); fight infection PLATELETSLess than 1 % (w/ WBC); clot blood RED BLOOD CELLS (ERYTHROCYTE) 45%, carry oxygen to tissues Hematocrit = % of RBC in body

5. Obj: Describe Blood Types

6. A = only A antigens B = only B antigens AB = A & B antigens O = neither A nor B antigens

7. O = Universal Donor AB = Universal Recipient

8. If someone does not receive proper blood during a transfusion: – It creates an immune response A person’s kidneys could shut down The person could get a fever, nausea or vomit – Blood clumps (agglutination) Can clog blood vessels

9. PhenotypeGenotype AAA or AO BBB or BO AB OOO A woman with blood type A (genotype AO) and a man with blood type AB (genotype AB) are going to have a baby. What are the possible blood types of the baby? AO A AAAO B ABBO A = 50% B = 25 % AB = 25% O = 0%

10. Obj: Label Heart Anatomy

11. LEFT ATRIUM RIGHT ATRIUM LEFT VENTRICLE RIGHT VENTRICLE

12. MITRAL TRICUSPID PULMONIC RA RV LA LV AORTIC

13. AORTA SUPERIOR VC Pulmonary veins INFERIOR VC RA RV LA LV Pulmonary arteries

14. Obj: Explain the circulatory system

15. Blood Vessel Name Direction of blood flow Usual Color of blood Why Arteries Veins Away from heart Towards heart Red Blue Blood is oxygenated Blood is unoxygenated

16. Pulmonic Circuit Circulation of blood flow from the R side of to lungs to L side of ** Pulmonic = lungs!

17. Systemic Circuit Circulation of blood flow from the L side of to tissues in rest of body to R side of

18. Blood Flow Through the Circulatory System Tissues in rest of body P Veins LA MV LV AV Aorta PA PV RV SVC & IVC RA TV BLOODFLOW THROUGH THE HEART Copy your class created flowchart into the one provided below. Use abbreviations (ex: Left Atrium = LA). When finished, use a red and blue colored pencil to indicate by outlining the box if blood flowing through here is oxygenated (red) or unoxygenated (blue).

19. Obj: Describe the dangers of high blood pressure

20. Vital Signs Taken to measure how the body is functioning 1.Temperature 2.Respiratory Rate (breathing rate) 3.Pulse 4.Blood Pressure

21. Pulse The pulse you feel when placing two fingers on your wrist is your left ventricle contracting or squeezing.

22. Blood Pressure _____________ 120 80 SYSTOLIC DIASTOLIC 100 or below = low (hypotension) 101-139 = normal 140 or above = high (hypertension )

23. Dangers of High Blood Pressure Low life expectancy Heart Attack Stroke Headaches Weakened heart Dizziness Sweating

24. Obj: Explain how the heart beats

25. Your heartbeat can be heard as a “Lub-dub” sound. The first heart sound (Lub) is caused by the mitral and tricuspid valves closing. The second heart sound (dub) is caused by the aortic and pulmonic valves closing.

26. Heart Murmurs Sounds like a swishing sound with the Lub dub sound. Caused by a valve not closing tightly or a hole in the septum

27. Obj: Characterize heart diseases/disorders

28. Cardiac Arrest When circulation completely stops to the rest of the body There is no pulse because the heart is not pumping blood Drug overdosing can cause someone to go into cardiac arrest

29. Heart Attacks A blood vessel becomes blocked and interrupts blood flow to the heart, causing heart muscle to die. A fatty material called plaque (plak) builds up over many years on the inside walls of the coronary arteries

30. Enlarged Heart Enlarged heart tells you that the heart is being overworked. This can mean there is something wrong with the heart anatomically Or there is too much physical pressure on the heart

31. Stroke Blood supply to brain is interrupted Brain cannot get oxygen FAST = acronym to help diagnose if person is having a stroke
