The male anopheles mosquito synthesizes an anticoagulant to keep the blood of its prey flowing during feeding.

Male Mosquito feeds on

Study carefully the following stages of life cycle of malarial parasite i.e., Plasmodium. Arrange these stages in the correct sequence and select the correct answer. 1. Sporozoites leave the blood stream and enter the liver cells of man. 2. Sporozoites present in the salivary glands of female Anopheles mosquito are injected into the blood stream of man. 3. The parasite reproduces asexually in RBCs, resulting in bursting of RBCs and causing the cycles of fever, relased parasites infect new RBCs. 4. The parasite reproduces asexually in liver cells, ultimately causing the rupturing of cells. 5. Two types of gametocytes i.e., microgametocytes and macrogametocytes develop in the RBCs. 6. Female Anopheleles mosquito takes up the gametocytes with blood meal of an infected person. 7. Mature infective stage of the parasite i.e., sporozoites escape from intestine and migrate to the mosquito's salivary glands. 8. Fertilisation and developmental stages of the parasite take place in mosquito's stomach.

Blood flow changes are least during exercise in

Which one of the following anticoagulant is added in blood during storage ?
