Target cells for releasing hormones are in the:
Anterior pituitary gland.
Hypothalamus.
Thyroid gland.
Posterior pituitary gland.
The Correct Answer is B
The hypothalamus is the part of the brain that produces hormones that control the pituitary gland.
The pituitary gland then releases hormones that target other endocrine glands, such as the thyroid, adrenal, and gonads.
Therefore, the hypothalamus is the source of releasing hormones for target cells in the anterior pituitary gland.
Choice A is wrong because the anterior pituitary gland does not produce releasing hormones, but responds to them by secreting other hormones.
Choice C is wrong because the thyroid gland does not produce releasing hormones, but responds to them by secreting thyroid hormones.
Choice D is wrong because the posterior pituitary gland does not produce releasing hormones, but stores and releases hormones made by the hypothalamus, such as oxytocin and antidiuretic hormone.

It is measured as part of a blood test and depends on the number and size of red blood cells. It is normally 40.7–50.3% for males and 36.1–44.3% for females.
Red blood cells contain hemoglobin, which transports oxygen and nutrients to the cells and tissues of the body.

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.
