What might happen if you have too low a count of platelets in your blood?
You might bleed extensively from even very small injuries.
What is the job of Plasma in your blood?
To transport stuff throughout your body.
Stem cells
Specifically Hematopoietic stem cells
200 point question!
Where the production of most of your blood start?
And what is made here?
Bone Marrow: Red Blood Cells, White Blood Cells, and Platelets.
How is plasma regenerated?
What might happen if you have too high a number of platelets in your blood?
You might get unnecessary clotting which could lead to strokes or heart attacks.
What are T-Lymphocytes responsible for?
They specifically attack infected cells and tumors.
What are B-Lymphocytes responsible for?
Attacking foreign materials that enter the body.
What are the four blood types?
A, B, O, and AB
What is the Universal Donor and Universal Receiver blood types?
Universal Donor = O-
Universal Receiver = AB+
What is External Respiration?
The exchange of O2 and CO2 between the lungs and blood
Do you have blue blood? Explain your answer.
No, your veins appear blue on the surface because of they way your skin interacts with the visible light spectra from the sun.
What are Neutrophils responsible for?
Act as the immediate response to against infection and disease.
Why is replacing lost blood a semi-complicated process?
What is the Rhesus factor and what does it cause?
It is a special protein attacked to blood cells.
IT causes your blood to be positive or negative typing.
What is Internal Respiration?
Exchange of O2 and CO2 between systemic blood vessels and tissues
Why does blood appear red? Fully explain your answer
Because you have lots of red blood cells and those red blood cells have hemoglobin.
What are the three types of White Blood Cells?
Neutrophils, B-Lymphocytes, T-Lymphocytes
How does your body know when to start making new blood when you lose any amount of blood?
Your tissues have sensors that detect they are not getting enough oxygen from blood.
A mom has a genotype of IAIA for blood and a genotype of +- for the rhesus factor. A dad has a genotype of IBi for blood and a genotype of -- for the rhesus factor. What are the odds a child of theirs will have the universal receiver blood type?
Come up to the board and show your work.
Universal receiver is AB+
50% chance AB blood type
50% chance - rhesus factor
1/2 x 1/2 = 1/4 or 25% chance of AB+
What are Alveoli?
Small sacs surrounded by blood capillaries which is where the specific gas exchange of oxygen and CO2
Daily Double ~ 1000 points
What are the four parts to your blood and what percentage is each part?
Plasma = 55%
Red Blood Cells = 40-45%
White Blood Cells = 1-2%
Platelets = 1-2%
Why do Red Blood Cells only survive up to 120 days on average? Explain your answer.
They have no nucleus so they cannot repair themselves if the cell takes any damage.
In terms of Antibodies and Antigens, explain why Someone with type A could not be given type AB blood?
The B-Antibodies in the A-Bloodstream would attack and kill the B-Antigens attached the AB Blood cells.
In terms of Antigens and Antibodies, explain any blood types can be given type O blood?
Type O blood has no antigens so when it enters the bloodstream of any blood type there is nothing for the antibodies in those bloodstreams to attack.
