When conmparing the flow of lymph in the lymphatic system with the flow of blood in the circulatory system. It can be said that the Lymphatic system also
A. uses a pump
B. contains fluid that travels in only one direction
C.Uses valves to prevent baclward flow
D. contains fluid that travels in a closed circuit
Can someone check my answer. My answer is (B)
d,
To determine the correct answer, let's compare the flow of lymph in the lymphatic system with the flow of blood in the circulatory system.
The lymphatic system is responsible for transporting lymph, a clear fluid that contains white blood cells, proteins, and waste materials, throughout the body. It plays a crucial role in the immune system.
The circulatory system, on the other hand, is responsible for transporting blood, which carries oxygen, nutrients, hormones, and waste products, throughout the body. It is essential for delivering oxygen and nutrients to the cells and removing waste materials from them.
Now, let's examine the options:
A. Uses a pump: The circulatory system uses the heart as a pump to propel blood through the arteries, veins, and capillaries. In contrast, the lymphatic system does not have a central pump like the heart. Instead, it relies on the contraction of surrounding muscles and the movement of your body to help propel lymph through lymphatic vessels. So, option A is incorrect.
B. Contains fluid that travels in only one direction: In the circulatory system, blood flows in a continuous loop, moving from the heart to arteries, capillaries, and then veins and back to the heart. Blood flows bidirectionally in arteries and veins. However, in the lymphatic system, lymph flows primarily in one direction due to the presence of one-way valves in lymphatic vessels that prevent backward flow. This ensures that lymph flows towards the heart. So, option B is correct.
C. Uses valves to prevent backward flow: As mentioned above, the lymphatic system relies on valves present in lymphatic vessels to prevent backward flow and maintain the unidirectional flow of lymph. Therefore, option C is correct.
D. Contains fluid that travels in a closed circuit: The circulatory system has a closed-loop arrangement, meaning blood continuously circulates in the body through arteries, capillaries, and veins. However, the lymphatic system is not a closed circuit. Lymphatic vessels collect lymph from various tissues and organs, transport it through lymph nodes for filtration and immune response, and eventually return it to the venous circulation near the heart. So, option D is incorrect.
Based on the comparison, the correct answer is B. Contains fluid that travels in only one direction.
