Communicable diseases key terms

rose black spot

A fungal disease affecting plants, characterized by purple or black spots on leaves.

fungicides

Chemical substances used to kill or inhibit the growth of fungi, often used to treat diseases like rose black spot.

malaria

In Protist diseases, malaria refers to a disease caused by protists that leads to recurrent episodes of fever and can be fatal. This matters in Communicable diseases because it supports the learning objective to state that the pathogens that cause malaria are protists. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

protist

A type of microorganism that includes the pathogens responsible for diseases such as malaria.

malarial protist

A type of protist that causes malaria and has a complex life cycle involving mosquitoes.

mosquito life cycle

The developmental stages of mosquitoes, which are essential for the transmission of the malarial protist.

malaria

In Protist diseases, malaria refers to a disease caused by protists that leads to recurrent episodes of fever. This matters in Communicable diseases because it supports the learning objective to describe malaria as causing recurrent episodes of fever. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

recurrent episodes

In Protist diseases, recurrent episodes refers to repeated occurrences of symptoms, such as fever, associated with malaria. This matters in Communicable diseases because it supports the learning objective to describe malaria as causing recurrent episodes of fever. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

malaria

A serious disease caused by protists, characterized by recurrent episodes of fever and can be fatal.

fatal

In Protist diseases, fatal refers to describes a condition or disease that can lead to death, as seen in severe cases of malaria. This matters in Communicable diseases because it supports the learning objective to explain that malaria can be fatal. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

malaria control

Methods used to manage malaria transmission, including preventing mosquito breeding and using mosquito nets.

mosquito breeding prevention

Strategies implemented to reduce the reproduction of mosquitoes, thereby decreasing the risk of malaria spread.

skin

The outer protective layer of the body that acts as a non-specific defence system against pathogens.

non-specific defence

A type of immune response that provides immediate protection against a wide range of pathogens without targeting specific ones.

non-specific defence system

A mechanism that provides general protection against pathogens without targeting specific invaders.

nose

In Human defence systems, nose refers to an organ that filters and traps pathogens in mucus, serving as a barrier to infection. This matters in Communicable diseases because it supports the learning objective to describe the nose as a non-specific defence system against pathogens. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

trachea

The trachea is a tube that connects the throat to the lungs, serving as a passage for air and a non-specific defence system against pathogens.

bronchi

The bronchi are the two main branches of the trachea that lead into the lungs, acting as non-specific defence systems by trapping and expelling pathogens.

stomach

An organ that acts as a non-specific defence system against pathogens by producing acid to kill harmful microorganisms.

non-specific defence

A type of immune response that provides immediate protection against a wide range of pathogens without targeting specific ones.

immune system

In Human defence systems, immune system refers to the complex network of cells and proteins that defends the body against pathogens. This matters in Communicable diseases because it supports the learning objective to explain the role of the immune system in the defence against disease. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

defence mechanisms

The processes and structures, such as white blood cells and antibodies, that protect the body from disease-causing organisms.

pathogen

In Human defence systems, pathogen refers to an organism that causes disease, such as bacteria, viruses, fungi, or parasites. This matters in Communicable diseases because it supports the learning objective to explain that if a pathogen enters the body the immune system tries to destroy it. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

immune system

In Human defence systems, immune system refers to the body's defense system that identifies and destroys pathogens that enter the body. This matters in Communicable diseases because it supports the learning objective to explain that if a pathogen enters the body the immune system tries to destroy it. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

phagocytosis

The process by which white blood cells engulf and digest pathogens to defend the body against infection.

white blood cells

Cells in the immune system that play a crucial role in defending the body against pathogens, including through mechanisms like phagocytosis.

antibodies

Proteins produced by white blood cells that specifically target and neutralize pathogens.

white blood cells

Cells in the immune system that help defend the body against infections and diseases by identifying and destroying pathogens.

antitoxins

In Human defence systems, antitoxins refers to substances produced by white blood cells that neutralize toxins released by pathogens. This matters in Communicable diseases because it supports the learning objective to explain how white blood cells defend against pathogens by producing antitoxins. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

white blood cells

Cells in the immune system that help defend the body against infections and pathogens.
