Introduction:
The lymph capillaries are present in the lymphatic system. It is a colorless fluid. It contains nutrients and ions absorbed and assimilated from the interstitial fluid. This fluid flows through the capillaries and enters the blood circulation again. It contains the white blood cells, bacteria, pathogens and cancerous cells which enter from the blood.
Answer to Problem 1MCQ
Correct answer:
Lymph capillary contains fluids with various blood cells, bacteria, pathogens and cancerous cells. Therefore, option d. is correct.
Explanation of Solution
Reason for the correct statement:
The lymph capillaries contain colorless fluids which are rich in nutrients which enter these capillaries from the blood stream. The constituents include blood cells, bacteria, and cancerous cells.
Option d. is given as “All of the above are correct”.
As, “the lymph capillaries contain blood cells, bacteria and cancerous cells which are absorbed from the interstitial fluid”, is the right answer.
Hence, option d. is correct.
Reasons for the incorrect statements:
Option a. is given as “Bacteria”.
Bacterial cells enter the lymph but there are other cells like cancer cells and blood cells also. So, it is a wrong answer.
Option b. is given as “Interstitial fluid”.
Lymph capillaries contain cancer cells and bacteria absorbed from the blood stream. So, it is a wrong answer.
Option c. is given as “Cancer cells”.
Cancer cells are present in the lymph capillaries but other cells like pathogens and white blood cells are also present. So, it is a wrong answer.
Hence, options a., b., and c. are incorrect.
The lymph capillary contains blood, bacteria, interstitial fluid and cancer cells. These cells are absorbed from the interstitial fluid.
