Lymph differs in composition from blood plasma mainly in that lymph:

Answer: Carries less protein and fewer red blood cells than plasma.

  • A Carries less protein and fewer red blood cells than plasma
  • B Carries oxygen far more efficiently than blood does
  • C Carries a notably higher concentration of red blood cells
  • D Contains no white blood cells of any kind

Correct answer: A. Carries less protein and fewer red blood cells than plasma

Explanation: Lymph is formed from tissue fluid and contains less protein than plasma, along with fewer red blood cells, though it does carry lymphocytes.

ECG: The Three Key WavesP wave(atrial depol.)QRS complex(ventricular depol.)T wave(ventricular repol.)QRS is the tallest spike - ventricles have far more muscle mass than the atria

A single ECG cycle: the P wave marks atrial depolarisation (contraction signal), the large QRS complex marks ventricular depolarisation, and the T wave marks ventricular repolarisation (recovery) before the next cycle begins.

Concept context

Blood, lymph, the heart, the cardiac cycle, blood pressure, and ECG. High NEET weightage.
