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.

Correct Answer is B
Explanation
The pancreas is an organ that has both endocrine and exocrine functions.
As an endocrine gland, it secretes hormones such as insulin and glucagon that regulate blood sugar levels.
As an exocrine gland, it releases substances that neutralize stomach acid and digestive enzymes that break down proteins, fats, and carbohydrates.
Choice A is wrong because the thyroid gland is only an endocrine gland.
It secretes hormones such as thyroxine and calcitonin that regulate metabolism and calcium levels.
Choice C is wrong because the anterior pituitary is only an endocrine gland.
It secretes hormones such as growth hormone, prolactin, and adrenocorticotropic hormone that regulate growth, lactation, and stress response.
Choice D is wrong because the liver is mainly an exocrine gland. It produces bile that helps digest fats and detoxifies the blood.
The liver also has some endocrine functions, such as producing insulin-like growth factor 1 and angiotensinogen, but these are not its primary roles.
Correct Answer is A
Explanation
The celiac artery supplies blood to the liver, spleen, and stomach.
It is one of the three major branches of the abdominal aorta, along with the superior mesenteric artery and the inferior mesenteric artery.
The celiac artery divides into three branches: the left gastric artery, the splenic artery, and the common hepatic artery.
Choice B is wrong because the brachiocephalic artery is a large vessel that arises from the aortic arch and supplies blood to the right side of the head and neck and the right arm.
It has no connection to the liver or spleen.
Choice C is wrong because the renal arteries are paired vessels that arise from the abdominal aorta and supply blood to the kidneys.
They are located below the superior mesenteric artery and above the inferior mesenteric artery.
Choice D is wrong because the tibial arteries are branches of the popliteal artery that supply blood to the lower leg and foot.
They are located in the posterior and anterior compartments of the leg.
The normal range of blood pressure in the celiac artery is about 100-120 mmHg systolic and 60-80 mmHg diastolic.
The normal range of blood flow in the celiac artery is about 200-300 ml/min. The normal diameter of the celiac artery is about 5-7 mm.
