📚 Practice ConceptWrite the differences between: (a) Blood and Lymph (b) Open and Closed system of circulation (c) Systole and Diastole (d) P-wave and T-wave
Consider the following statements about lymph and circulatory pathways: 1. Lymph is a colourless fluid containing specialised lymphocytes responsible for immune responses. 2. Exchange of nutrients and gases between blood and tissues occurs through interstitial fluid. 3. Open circulatory system is present in arthropods and molluscs, where blood flows into body sinuses. 4.
