The lymph nodes of the axillary region receive lymph mainly from the:
Upper limb and mammary gland.
Abdominal viscera.
Scalp and face.
Thoracic viscera.
The Correct Answer is A
The lymph nodes of the axillary region receive lymph mainly from the upper limb and mammary gland.
This is because the axillary lymph nodes are located in the armpit area and drain the lymph vessels from the lateral quadrants of the breast and the arm.
Choice B is wrong because the abdominal viscera are drained by the celiac, superior mesenteric, and inferior mesenteric lymph nodes.
Choice C is wrong because the scalp and face are drained by the cervical lymph nodes.
Choice D is wrong because the thoracic viscera are drained by the bronchopulmonary, tracheobronchial, parasternal, and posterior mediastinal lymph nodes.

Explanation
This is because blood type AB has both A and B antigens on the surface of red blood cells.
Antigens are protein molecules that can trigger an immune response if they are foreign to the body.
Choice A is wrong because antigen B only is present in blood type B.
Choice B is wrong because neither antigens A nor B are present in blood type O.
Choice C is wrong because antigen A only is present in blood type A.
Normal ranges for blood types vary by population, but according to the NHS, about 3% of people in the UK have blood type AB.
Correct Answer is B
Explanation
A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestines.
The lacteals merge to form larger lymphatic vessels that transport chyle (a milky fluid containing fat and lymph) to the thoracic duct where it is emptied into the bloodstream at the subclavian vein.
Choice A is wrong because it is the opposite of the true statement.
Lacteals are not false, they are real structures that play an important role in fat absorption and transport.
