Blood Markers Flashcards
What is the primary function of red blood cells (RBCs)?
Transport oxygen to tissues via haemoglobin.
What happens to white blood cell (WBC) counts after acute exercise?
They typically increase, indicating immune system activation.
What is the role of platelets in the bloodstream?
Platelets are critical for clot formation and tissue repair.
Which blood marker is a general indicator of inflammation?
C-reactive protein (CRP).
What is fibrinogen, and how does it change during inflammation?
Fibrinogen is involved in clot formation; its levels increase during inflammation.
What does a high erythrocyte sedimentation rate (ESR) indicate?
Elevated ESR suggests the presence of inflammation.
What cytokine is rapidly released by skeletal muscles during exercise?
Interleukin-6 (IL-6).
How does albumin change during chronic inflammation?
Albumin levels decrease due to vascular leakage.
Which marker is used to detect cardiac injury, such as a heart attack?
Troponin.
What is the significance of rheumatoid factor or anti-CCP in blood tests?
They are autoantibodies associated with rheumatoid arthritis.
How does regular training affect red blood cell count?
It increases RBC count and haemoglobin mass, improving oxygen transport.
What does an elevated CRP level combined with other tests indicate?
Systemic inflammation or an acute inflammatory response.
What happens to plasma volume and albumin during acute exercise?
Plasma volume decreases, leading to an apparent increase in albumin concentration.
What does a significant increase in IL-6 post-exercise suggest?
Activation of the inflammatory and repair processes.
What is the role of cytokines in the immune system?
Cytokines coordinate immune responses and mediate inflammation.
