16
Q

What is erythropoiesis

A

RBC production

17
Q

What does sickle cell consist of

A

Defective beta chain in Hb molecules

Caused by mutation in DNA coding for 1 amino acid

Causes RBCs to become rigid, fragile, & sickle shaped

Hb molecules stick together after releasing O2

18
Q

What are the different types of defective or insufficient cells of amenia

A

Iron deficiency Armenia

Sickle cell amenia

Pernicious amenia

19
Q

Who has higher RBCs production males or females

20
Q

What’s the natural way of blood doping

A

Exposing blood to low O2

21
Q

what’s the cheating way of blood doping

A

Removing blood while training

Re infusing RBCs before competition

22
Q

What’s the drug abuse of blood doping?

A

Taking EPO pills

Increase hematocrit up to 65% if a person is heathy

23
Q

What does blood doping do?

A

Can increase blood viscosity

Increase blood resistance

24
Q

What’s the three phase of hemostasis

A

Vascular phase

Platelet phase

Conagulation phase

25
What is homestasis
The body's way of regulating internal stability to remain constant
26
What's vascular phase
Endothelial cells contract and release endothelin Smooth muscles contract and divide/repair Endothelial cells become sticky
27
What does platelet phase consist of
Form platelet plug Platelets stick to endothelial cells 15 secs after injury Platelets release chemical signals to stimulate clotting process
28
What does coagulation phase consist of
Requires clotting factors Ca2+,requires 2 proteins,Vitamin k End result in fibrin produced Begins 30 secs after injury Can take 8-18 min to complete Bleeding usually stops after 1-4 mins
