What system destroys pathogens that enter the body?
Essentials of Anatomy and Physiology 5th ed. (Scranton and Sanders)
| Term | Definition | Organs |
|---|---|---|
| Lymphatic | -Returns tissue fluid to the blood – Destroys pathogens that enter the body and provides immunity | spleen lymph nodes |
| Respiratory | – Exchanges oxygen and carbon dioxide between the air and blood | lungs trachea larynx diaphragm |
Which body system moves the skeleton and produces heat?
Muscular system
Muscular system (Cardiac, Smooth, and Skeletal Muscles) Skeletal muscles are also responsible for maintaining posture and producing heat.
What organ system regulates body functions by means of impulses?
nervous system
The nervous system is made up of the brain, the spinal cord, and nerves. One of the most important systems in your body, the nervous system is your body’s control system. It sends, receives, and processes nerve impulses throughout the body.
Which systems control processes in the human body?
The nervous system is the control center of the human body. It is made up of the brain, spinal cord, and nerves. It receives and interprets stimuli and transmits impulses to organs. Your brain uses the information it receives to coordinate all of your actions and reactions.
How does your body destroy the pathogens you swallow?
Most pathogens that you swallow are destroyed by chemicals in your saliva or by stomach acid. Pathogens that do get into your body can trigger the inflammatory response, the body’s second line of defense. In the inflammatory response, fluid and white blood cells leak from blood vessels into nearby tissues.
What are the 3 most important body systems?
The main systems of the human body are:
- Circulatory system / Cardiovascular system:
- Digestive system and Excretory system:
- Endocrine system:
- Integumentary system / Exocrine system:
- Immune system and lymphatic system:
- Muscular system:
- Nervous system:
- Renal system and Urinary system.
What is the most important system in the human body?
While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The human nervous system is responsible for coordinating every movement and action your body makes.
What are the two great controlling system of the body?
What are the two great controlling systems of the body? Nervous system and endocrine system. The major subdivisions are the central nervous system which includes the brain and spinal cord, and the peripheral nervous system which is mainly nerves.
How can I destroy my immune system?
Your immune system can also be weakened by smoking, alcohol, and poor nutrition. AIDS. HIV, which causes AIDS, is an acquired viral infection that destroys important white blood cells and weakens the immune system. People with HIV/AIDS become seriously ill with infections that most people can fight off.
How does heat affect the growth of microorganisms?
Heat is lethal to microorganisms, but each species has its own particular heat tolerance. During a thermal destruction process, such as pasteurization, the rate of destruction is logarithmic, as is their rate of growth.
What happens to microorganisms during thermal destruction?
Thermal Destruction of Microorganisms Heat is lethal to microorganisms, but each species has its own particular heat tolerance. During a thermal destruction process, such as pasteurization, the rate of destruction is logarithmic, as is their rate of growth.
Why are pathogens destroyed at a higher temperature?
Due to the differences in Z values, it is apparent that at higher temperatures for shorter times, a region exists (shaded area) where pathogens can be destroyed while vitamins can be maintained. The same holds true for other quality factors such as colour and flavour components.
How much heat is required to kill bacteria in food?
Mishandling of raw and cooked foods allows bacteria to grow. The temperature range in which most bacteria grow is between 40 degrees F (5 degrees C) and 140 degrees F (60 degrees C). Raw and cooked foods should not be kept in this danger zone any longer than absolutely necessary.
