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.

Correct Answer is A
Explanation
This is because anatomy and physiology are closely related branches of biology that study the structure and function of living organisms respectively.
Anatomy describes the shape, size, location, and relationships of body parts, while physiology explains how those parts work together to maintain life.
For example, the anatomy of the heart determines how it pumps blood, and the anatomy of the lungs determines how they exchange gases.
Choice B is wrong because our understanding of both anatomy and physiology is constantly changing as new discoveries are made in the field of biology.
Choice C is wrong because body parts take up space regardless of their physiological functions.
Choice D is wrong because physiological functions are not limited to an organism, but can also occur at the cellular, tissue, organ, and system levels.
Correct Answer is B
Explanation
The correct answer is choice B. False.
Arteries are strong, elastic vessels that carry blood away from the heart, except for the coronary arteries that supply blood to the heart muscle.
These are the first arteries to branch off the aorta, which is the main artery that takes blood to the body from the left ventricle.
Choice A is wrong because it contradicts the definition of arteries. Arteries carry blood away from the heart, not to the heart.
