Verified step by step guidance

Step 1: Understand the function of lymphatic capillaries. Lymphatic capillaries are small, thin-walled vessels that collect excess interstitial fluid and transport it to larger lymphatic vessels. They play a key role in maintaining fluid balance and immune function.

Step 2: Recall the distribution of lymphatic capillaries in the body. Lymphatic capillaries are present in most tissues but are absent in certain areas, such as the central nervous system (CNS), cartilage, bone marrow, and the cornea of the eye.

Step 3: Eliminate incorrect options based on anatomical knowledge. For example, lymphatic capillaries are not present in cartilage and bone marrow, so the option stating 'All tissues including cartilage and bone marrow' is incorrect.

Step 4: Consider the digestive tract and skin. While lymphatic capillaries are present in these areas, they are not exclusive to them. Therefore, the options 'Only in the digestive tract' and 'Only in the skin' are also incorrect.

Step 5: Select the correct answer based on the distribution of lymphatic capillaries. The correct answer is 'Most body tissues except the central nervous system,' as this accurately reflects their presence in the body.
