Introduction: The distribution of nutrients and the transportation of gases take place by using the body fluid. A pumping organ pushes the fluid to various parts of the body. The presence of hemolymph is observed in the organisms having an open circulatory system.
Answer to Problem 1TY
Correct answer: The hemolymph differs from the blood as it is a mixed fluid present in the hemocoel. Hence, the correct answer is option b.
Explanation of Solution
Reason for correct answer:
In an open circulatory system, the combination of interstitial fluid that surrounds the cells gets mixed with the fluid carried by the blood vessels in a single chamber. The mixed fluid is known as hemolymph and the body cavity is known as hemocoel.
Option b. is given as “is a mixed fluid found in the hemocoel”.
The blood differs from the hemolymph. Blood circulates in the blood vessels while hemolymph is a mixed fluid present in the hemocoel. Hence, the correct answer is option b.
Reason for incorrect answer:
Option a. is given as, “does not contain blood cell”.
Hemolymph is responsible for the transportation of the gases to various organs of the body. The transportation of gases takes place by blood cells. Hence, option a. is incorrect.
Option c. is given as, “circulates through the closed circulatory system only”.
The hemolymph is the combination of blood and lymph. The fusion of both fluids takes place in the open circulatory system inside the hemocoel. Hence, option c. is incorrect.
Option d. is given as, “functions only in defense of the body and not transport”.
The hemolymph is responsible for the transportation of gases to the tissues. The transportation of gases is also a function of hemolymph. Hence, option d. is incorrect.
Option e. is given as, “does not pass through the heart”.
Each body fluid needs pressure for its circulation in the body, which is provided by the heart. Every circulation that occurs in the body of the organism will pass through the heart. Hence, option e. is incorrect.
Hence, the options a., c., d., and e. are incorrect.
Hemolymph is a mixed fluid found in the hemocoel which differs from the blood.
