Blood Flashcards
How much blood is in the body?
4- 5 liters
How much of the blood is Plasma
About 55%
White blood cells is what percentage of the body?
Less than 1%
How much of the body is red blood cells?
45%
White Blood cells is also called
Leukocytes
Red Blood cells is also called
Erythrocytes
What is Plasma
-The liquid portion of our blood without plasma -our blood would be all formed elements
-Contains no cells but several proteins
-91% water
-remainder proteins and electrolytes
Proteins and electrolytes found in plasma
- Albumin
- Clotting Factors
- Antibodies
- Glucose
- Lipids
- Hormones
- Wastes
- Drugs
- Electrolytes
- Vitamins
Hemoglobin
helps with PH balance
- RBCs are filled with Hemoglobin
- Hemoglobin is an iron-containing pigment that carries 02 and c02
- Carries Hydrogen ions
When is blood DARK
When Co2 content is higher
When is blood lighter
When o2 is present
PH must remain
7.35 - 7.45
Hydrogen are what?
Acidic, lowering PH balance
Leukocytes does what?
Responsible for immunity
2 types of Leukocytes
Granulocytes (neutrophils, Basophils, Eosinophils) & Agranulocytes (lymphocytes, Monocytes)
What are Platelets
- Cell fragments
- 150 - 350, 0000 Per Cubic MM
- (blood clotting)
- 1/3 remains in the spleen as back - up significant bleeding
What is Hematopoiesis?
Formation of blood cells
1st cell to make blood is called
“Multi-Potential Stem cell”
Lymphoid stem cells & Myeloid Stem Produce what?
Lymphoid: Produce Lymphocytes
Myeloid: Produce everything else
What is mineral needed for clotting
Calcium
3 Steps of clotting
Prothrombinase > Prothrobin > Thrombin
What does Thrombin convert to
Fibrinogen which convert into Fibrin
Fibrin does what to form the clot
Trap RBCs and Platelets to form the clot
Platelets does what?
Plug holes
RBC Live
120 Days
WBC Live
9 days
Functions of the blood
Carries oxygen/nutrients to tissues.
Carries Hormones to organs
Hemostasis
Immunology
In plasma
Albumin, clotting factors, antibodies, hormones, waste, drugs, glucose, lipids, vitamins, electrolytes
Glucose
Source of energy
Lipids
Reserve energy when glucose not available
Rbc are filled with
Hemoglobin containing pigment that carries 02 & Co2
What shape is Erythrocytes
Biconcave. change shape as it travels through cardiovascular
Hemoglobin is iron containing that carries what?
Co2 & O2. And also carries hydrogen ions
Hydrogen ions change the shape of..
Hemoglobin, making them less able to carry O2
What happens if our blood can’t carry o2?
Hypoxia. lose energy. Cause organ damage.
Ph not fixed
Cause hypoxic
Neutrophils
Defense against bacterial infection
Basophils
Phagocytosis during hypersensitive responses
Eosinophils
Increase in allergies and parasitic infections
Lymphocytes
Acquired immunity
Monocytes
Largest WBC help w/ infections
Myeloid stem cells produce
Everything else
Lymphoid produce
lymphocytes
Prothrombinase converts
Prothrombin> thrombin> calcium > thrombin change to Fibrinogen> Fibrin. Fibrin traps RBC to form the clot
