Lab Test 1 Flashcards
Blood Elements
- Formed elements: RBCs, WBCs, Platelets
- Plasma= aqueous mixture: Proteins (albumin), ions (sodium, chloride, and calcium)
Lab 1 (Blood and Blood Cells): Name and describe the tests that were done to detect molecules in the plasma.
- Benedicts Test: testing for glucose
- Biruet Reagant Test: testing for peptide bonds;
- AgNo3: testing for chloride ions;
Lab 1 (Blood and Blood Cells): How were the tests conducted, did you have to boil the sample, etc?
- Sample is put into test tube
- Drops of reagent are added
- Solution is boiled to catalyze reaction
- Observed color change (if any)
Lab 1: Methods for testing & visualizing blood
- Centrifuge: allows to separate layers of different blood layers (formed elements, plasma, etc). Works through relative densities of each part.
- Microscope: Look at specific layers at magnification so we can study visual details
- Complete Blood Count (CBC): samples of blood are drawn from patient and sent to lab for testing. The CBC is interpreted by looking at different blood values and comparing against the norm. Deviations of the norm can suggest a type of disease.
- Chem 7 or Basic Metabolic Panel (BMP): detect levels of glucose, sodium, potassium, CO2, Creatinine, Bloof Urea Nitrogen (BUN)
Lab 1: Identify The Formed elements using models as well as under microscope- LABEL FIGURE!

Lab 1 (Blood and Blood Cells): What reagents were used in these tests and what you observe if the reaction was positive/negative?
- Benedicts Test: Blue Reagent
- Postive: Yellow/ Green or Red (really high levels of glucose)
- Negative: Blue - Biruet Reagent Test: Blue Reagent
- Postive: Deep Purple
- Negative: Blue - Silver Nitrate Test (AgNO3): Clear Reagent
- Positive: milky/ cloudy precipitant
- Negative: Clear

Lab 3: Inferior Vena Cava
Returns blood from lower body to the right atrium
Lab 3: Superior Vena Cava
Returns blood from the upper bodd to the right atrium
Lab 3: Base
Located at the top of the heart. Broad area where the great vessels (pulmonary trunk, aaorta,vena cava) exit from the heart
Lab 3:Apex
The bottom of the heart
Lab 3: Right Atrium
Upper chamber on the right side of the heart; recieves blood from the vena cavae and the cardiac sinus
Lab 3: Right ventricle
Lower chamber of the heart on the right side
Lab 3: Left atrium
Upper chamber on the left side
Lab 3: Left Ventricle
Lower chamber on the left side of the heart
Lab 3: Interventricuar septum
The part of the heart that seperates the left from the right side of the heart
Lab 3: Pulmonary Trunk
Great vessel that exits the heart from the right ventricle
Lab 3: Pulmonary Arteries
Bring blood from the pulmonary trunk to the lungs
Lab 3: Pulmonary Veins
Return blood from the lungs to the left atrium
Lab 3: Aaorta
Great vessel that exsts from the left ventricle
Lab 3: Tricuspid Valve
Valve between the left atrium and ventricle. Also known as the right atrioventricular valve
Lab 3: Bicuspid Valve
Valve between the left atrium and ventricle. Also known as the left atrioventricular valve.
Lab 3: Pulmonary seminlunar valve
Valve between the right ventricle and the pulmonary trunk
Lab 3: Aaortic Semilunar Valve
Valve between the left ventricle and the aaorta
Chordae Tendinae
Fibrous chords that attach the atrioventricular valves to the papillary muscles
Papillary Muscles
Muscles that anchor the chordae tenindus
Lab 3: Epicardium
Serous membrane that attaches directly to the heart muscles
Lab 3: Endocardium
Squamous epithelial tissue that lines the inner suraces of the heart
