Verified step by step guidance

Step 1: Begin by understanding the nature of fat-soluble nutrients. Fat-soluble nutrients, such as vitamins A, D, E, and K, are absorbed in the small intestine and require specific transport mechanisms due to their solubility in fat rather than water.

Step 2: Recall the role of the lymphatic system in nutrient transport. The lymphatic system is responsible for transporting lipids and fat-soluble nutrients from the digestive system to the bloodstream. This occurs via structures called lacteals, which are specialized lymphatic vessels in the small intestine.

Step 3: Compare the functions of the other systems listed in the options. The respiratory system is involved in gas exchange, the endocrine system regulates hormones, and the urinary system removes waste products. None of these systems are directly involved in transporting fat-soluble nutrients.

Step 4: Recognize that the lymphatic system is the correct answer because it specifically handles the transport of fat-soluble nutrients through lymph fluid before they enter the bloodstream.

Step 5: Conclude that the correct answer is 'lymphatic' based on the physiological role of the lymphatic system in nutrient absorption and transport.
