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
Component Function/Info
PLASMA 55%, made up mostly of water, liquid part of blood
WHITE BLOOD CELLS (LEUKOCYTE)
Less than 1% (w/ platelets); fight infection
PLATELETS Less than 1 % (w/ WBC); clot blood
RED BLOOD CELLS (ERYTHROCYTE)
45%, carry oxygen to tissues
Hematocrit = % of RBC in body
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
Phenotype Genotype
A AA or AO
B BB or BO
AB AB
O OO
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?

A AA AO
B AB BO
A = 50%B = 25 %AB = 25%O = 0%

TVBLOODFLOW 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).
Vital Signs
Taken to measure how the body is functioning
1. Temperature2. Respiratory Rate (breathing rate)3. Pulse4. Blood Pressure
PulseThe pulse you feel when placing two fingers on
your wrist is your left ventricle contracting or squeezing.
Blood Pressure
_____________120
80
SYSTOLIC
DIASTOLIC
100 or below = low (hypotension)101-139 = normal140 or above = high (hypertension)
Dangers of High Blood Pressure
• Low life expectancy• Heart Attack• Stroke• Headaches• Weakened heart• Dizziness• Sweating
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.
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
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
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
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
Stroke• Blood supply to brain is interrupted• Brain cannot get oxygen• FAST = acronym to help diagnose if
person is having a stroke
