The type of resistance that is acquired as a result of developing a disease is:
Naturally acquired passive immunity.
Naturally acquired active immunity.
Artificially acquired active immunity.
Artificially acquired passive immunity.
The Correct Answer is B
Naturally acquired active immunity is the type of resistance that is acquired as a result of developing a disease.
This means that the immune system produces antibodies to fight off the infection and remembers the pathogen for future protection.
This type of immunity is long-lasting and sometimes life-long.
Choice A is wrong because naturally acquired passive immunity is the type of resistance that is acquired when a person receives antibodies from another source, such as from the mother through the placenta or breast milk.
This type of immunity is temporary and lasts only for a few weeks or months.
Choice C is wrong because artificially acquired active immunity is the type of resistance that is acquired when a person receives a vaccine that contains a weakened or killed form of the disease organism.
This triggers the immune system to produce antibodies and memory cells without causing the actual disease.
This type of immunity can last for years or decades, depending on the vaccine.
Choice D is wrong because artificially acquired passive immunity is the type of resistance that is acquired when a person receives antibody-containing blood products, such as immune globulin, that provide immediate protection from a specific disease.
This type of immunity is also temporary and lasts only for a few weeks or months.

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.
Correct Answer is B
Explanation
The endocardium is the thin inner lining of the heart chambers and also forms the surface of the heart valves.
Some possible explanations for the other choices are:
Choice A is wrong because the pericardium is the sac that surrounds the heart and consists of two layers: the fibrous pericardium and the serous pericardium.
Choice C is wrong because the myocardium is the thick middle layer of muscle that allows the heart chambers to contract and relax to pump blood to the body.
Choice D is wrong because epicardium is another name for the visceral layer of the serous pericardium that is fused to the heart and is part of the heart wall.
