How do lymphatic vessels differ from blood vessels in terms of permeability?

Blood vessels are more permeable than lymphatic vessels

Both blood vessels and lymphatic vessels have similar permeability

Lymphatic vessels have valves that control permeability

Lymphatic vessels are semi-permeable, allowing easier passage of fluid (correct)

What is the function of Lymphocytes in the lymphatic system?

To prevent backflow of lymph by using valves

To transport oxygen and nutrients to the cells

To supply nutrients to the interstitial space

To filter the lymph in the lymph nodes (correct)

Where are lymphatic vessels not present in the body according to the text?

Heart, Liver, Kidneys, Lungs

Epidermis, Bone marrow, CNS, Cartilages (correct)

Muscles, Stomach, Pancreas, Intestines
