Correct Answer is D
Explanation
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.

Explanation
Innate defenses counter specific disease-causing agents, whereas adaptive defenses include mechanical and chemical barriers.
Choice A is wrong because it confuses the two types of defenses.
Innate defenses are nonspecific and include physical barriers such as the skin, molecules that are toxic to invaders, and phagocytic cells that ingest invaders.
Adaptive defenses are specific and are activated by the innate immune system.
They involve the production of antibodies and specialized cells that recognize and eliminate specific pathogens.
Normal ranges are not applicable in this question as it is about the definitions of innate and adaptive defenses.
