Blood (FINAL) Flashcards
What is the general role of blood?
Blood is a transport agent
What type of things does blood transport around the body?
- Gases (O2, CO2)
- Nutrients
- Hormones
- Waste
What are the four components that make up blood?
- Plasma
- Leukocytes (WBC’s)
- Erythrocytes (RBC’s)
- Platelets
Which of the componets of blood are made in the bone marrow?
- Leukocytes (WBC’s)
- Erythrocytes (RBC’s)
- Platelets
What are hemocytoblasts?
Blood cell maker (stem cell)
Which of the component(s) of the blood does diet aid in its formation?
Erythrocytes (RBC’s)
Needs iron (Fe2+)
What is the function of plasma?
Plasma is a liquid that transports:
- Hormonnes
- Glucose
- Wastes
- Everything els
What organ(s) detects O2 in the body?
- Liver
- Kidney
When there is too much O2 in the body what increases in order for the number of RBCs to decrease?
Decrease in EPO (Erythropoietin) = Decrease in RBCs
When there is too little O2 in the body what increases in order for the number of RBCs to increase?
Increase in EPO (Erythropoietin) = Increase in RBCs
What is the general function of leukocytes (WBCs)?
Immunity
What is the general purpose of erythrocytes (RBCs)?
Carries O2
What is the general function of platelets?
Clotting
What are the 8 steps of processing old RBCs?
- Old RBCs last 6 weeks
- Sent to the liver
- The liver takes the hemoglobin out of the old RBCs
- The iron from the hemoglobin is sent to the bone marrow
- Everything else except the hemoglobin is turned into bilirubin
- Bilirubin is turned into bile
- The bile is sent through the small intestines
- Eventually takes it to the toilet (waste)
How long do RBCs last?
~6 weeks
What organ does old RBCs get sent to?
The liver
What does the liver do to the old RBC’s
Takes the hemoglobin (Fe carring protein) out of the old RBCs
Where is the Fe2+ (iron) sent to after the liver is done processing the hemoglobin?
To the bone marrow
What does the liver turn “everything else” that is not hemoglobin from the old RBCs?
To bilirubin
What is bilirubin?
(Besides the name Dr. Lector gave the senator of Buffola Bill)
The waste product of the breaking down of old RBC in the liver
Which organ produces bilirubin?
Liver
What condition is the result of excess bilirubin in the body?
Jaundice
After the liver has turned parts of the old RBCs into bilirubin, it is then turned into what?
Bile
Bile goes through what organ to be eventually expelled in the toilet as waste?
Small intestines
What type of blood can a patient get with type A?
Type A & O
What type of blood can a patient get with type AB?
Types A, B, AB, & O
What type of blood can a patient get with type B?
Type B & O
What type of blood can a patient get with type O?
Type O
Which blood type is a universal donor?
Type O
Which blood type is the universal recipient?
Type AB
A blood donor has type A blood, who can the donor give blood to?
Recipients with blood types:
- A
- AB
A blood donor has type B blood, who can the donor give blood to?
Recipients with blood types:
- B
- AB
