Stage 4 Recap
The body system involved in extracting nutrients and delivering them to the blood stream.
What is the digestive system?
The part of the nervous system containing the brain and spinal chord.
What is the central nervous system?
The process of maintaining internal body conditions.
What is homeostasis?
The causal agent of an infectious disease.
What is a pathogen?
The place where digestion begins.
What is the mouth?
The tubes that connect the bladder to the kidneys.
What are ureters?
The part of the brain responsible for the control of involuntary movement, like balance.
What is the cerebellum?
The process that regulates a specific internal condition by opposing an initial stimulus.
What are negative feedback loops?
When a disease is spread without direct contact between hosts.
What is indirected transmission?
An involuntary/immediate reaction the body take in response to a stimulus.
What is a reflex?
The vessel that carries blood back to the heart from the lungs.
What is the pulmonary vein?
The type of neuron responsible for controlling glands outside of the brain.
What is a motor neuron?
Ion levels, water levels, blood pH, temperature, blood pressure, hormone levels, gas levels.
What are example of conditions controlled by homeostasis?
A normal level of a disease in the location it is usually found.
What is endemic disease?
A mechanism which results in a increase of an initial stimulus, for example the release of oxytocin during child birth.
What is a positive feedback loop?
The location of gaseous exchange in the mammalian respiratory system.
What are alveoli?
The chemical messengers that travel through the blood.
What is a hormone?
The part of the CNS responsible for interpreting signals from thermoreceptors to regulate body temperature.
What is the hypothalamus?
Genetic traits, nutrition, environmental factors, malfunctioning cells.
What are the four causes of non-infectious diseases?
A misfolded protein which can lead to disease, and be spread between hosts.
What is a prion?
The tissue responsible for separating the trachea and the oesophagus during breathing and swallowing.
What is the epiglottis?
The gland directly controlled by the hypothalamus, which controls many other glands within the body.
What is the pituitary gland?
The storage unit of glucose created by the liver in response to elevated levels of insulin and blood sugar.
What is glycogen?
Proteins involved in fighting pathogens which can lyse or opsonise cells, and/or increase inflammation.
What are complement proteins?
A chemical messenger involved in recruiting blood cells and fluid to the site of an infection.
What are cytokines?
