Vedclass · Answer

(A) Valves are specialized structures that ensure the unidirectional flow of blood and lymph. In the circulatory system,valves are found in the hearts of both vertebrates and invertebrates to prevent backflow during contraction. Furthermore,they are present in the blood vessels (specifically veins) of many animals to assist in venous return against gravity. Additionally,valves are present in the lymphatic vessels of vertebrates to maintain the unidirectional flow of lymph towards the venous system. Therefore,option $A$ is the most comprehensive and accurate description.

$(b)$ Monocytes	$(II)$ Are the agranulocytes
$(c)$ Neutrophils	$(III)$ Most abundant cells of the total WBCs
$(d)$ Basophils	$(IV)$ Inflammatory reactions
