A person who is stressed usually will have increased:
Resistance to infections.
Activity of the spleen and other lymphatic organs.
Number of lymphocytes in the blood.
Blood pressure.
The Correct Answer is D
A person who is stressed usually will have increased blood pressure because stress causes the body to release a surge of hormones that make the heart beat faster and the blood vessels narrow.
This can cause a temporary spike in blood pressure, which usually returns to normal once the stressor is gone.
Choice A is wrong because resistance to infections is not increased by stress.
In fact, chronic stress can weaken the immune system and make a person more prone to infections.
Choice B is wrong because the activity of the spleen and other lymphatic organs is not increased by stress.
The spleen and other lymphatic organs are part of the immune system, which can be affected by chronic stress in a negative way.
Choice C is wrong because the number of lymphocytes in the blood is not increased by stress. Lymphocytes are a type of white blood cell that help fight infections.
Chronic stress can reduce the number and function of lymphocytes and impair the immune response.

Correct Answer is A
Explanation
Calcitonin is a hormone that protects against excessive blood calcium levels by inhibiting bone turnover and decreasing reabsorption.
It is produced by the thyroid gland and acts on both osteoclasts and osteoblasts.
Choice B is wrong because parathyroid hormone (PTH) stimulates both resorption and formation of bone, and controls the level of calcium in the blood.
Choice C is wrong because thyroxine is a thyroid hormone that is required for skeletal maturation and influences adult bone maintenance but does not directly affect calcium deposition into bone.
Choice D is wrong because insulin is a hormone that regulates both bone formation and bone resorption but does not specifically stimulate calcium deposition into bone.
Correct Answer is C
Explanation
This type of blood cell is a granulocyte that has a bi-lobed nucleus and red granules in the cytoplasm.
Eosinophils are involved in allergic reactions and parasitic infections.
Choice A is wrong because basophils are granulocytes that have a lobed nucleus and dark blue or purple granules in the cytoplasm.
Basophils are involved in inflammatory responses and histamine release.
Choice B is wrong because lymphocytes are agranulocytes that have a large round nucleus and a thin rim of cytoplasm.
Lymphocytes are involved in immune responses and produce antibodies.
Choice D is wrong because monocytes are agranulocytes that have a kidney-shaped nucleus and a pale blue cytoplasm.
Monocytes are involved in phagocytosis and tissue repair.
Choice E is wrong because neutrophils are granulocytes that have a multi-lobed nucleus and pale pink granules in the cytoplasm.
Neutrophils are involved in bacterial infections and inflammation.
