Which human organ system returns excess interstitial fluid to the blood?
A
Lymphatic system
B
Respiratory system
C
Endocrine system
D
Digestive system
Verified step by step guidance1
Step 1: Begin by understanding the function of interstitial fluid. Interstitial fluid is the fluid that surrounds cells in tissues, providing nutrients and removing waste. Excess interstitial fluid must be returned to the bloodstream to maintain fluid balance.
Step 2: Review the role of the lymphatic system. The lymphatic system is responsible for collecting excess interstitial fluid, filtering it through lymph nodes, and returning it to the circulatory system via lymphatic vessels.
Step 3: Compare the functions of the other organ systems listed. The respiratory system is involved in gas exchange, the endocrine system regulates hormones, and the digestive system processes food. None of these systems are directly involved in returning interstitial fluid to the blood.
Step 4: Identify the correct answer based on the function described. The lymphatic system is the organ system that specifically handles the return of excess interstitial fluid to the blood.
Step 5: Conclude that the lymphatic system is the correct answer, as it matches the function described in the problem.
