The three lines of defense your body has against disease include all except
• physical and chemical defenses.
• inflammation.
• immune system.
• scarring.
scarring.
Antibodies are produced by B cells.
The bot is correct.
b cells and h cells are two important cells in the immune system that help fight infection; true or false?
False. The correct names of the two important cells in the immune system are B cells and T cells, not B cells and H cells. They work together to fight against infections and other threats to the body's health.
antibodies are produced by;
B cells
T cells
Red blood cells
Lymph nodes
To determine the correct answer, let's analyze each option:
1. Physical and chemical defenses: This refers to the external barriers of the body, such as the skin, mucus membranes, and the acidic environment of the stomach. These barriers act as a wall, preventing pathogens from entering the body.
2. Inflammation: Inflammation is a part of the body's immune response to infection or injury. It involves increased blood flow to the affected area, leading to redness, swelling, and warmth. Inflammation helps in neutralizing pathogens and repairing damaged tissues.
3. Immune system: The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens. It comprises both innate and adaptive immunity, which include various cells (such as white blood cells), antibodies, and other immune molecules.
4. Scarring: Scarring is the result of the body's healing process after injury or tissue damage. It occurs when connective tissue replaces the damaged cells. However, scarring is not considered a defense mechanism against disease or infection.
Based on the given options, the answer would be "scarring" because it does not serve as a defense mechanism against disease.
