What is a result of the creation of antibiotics that treated bacterial infections

What is a decrease in the number of bacterial infections OR antibiotic resistance

100

What is the function of a nerve cell?

To detect information and relay 

100
If the body cannot effectively maintain homeostasis, it means there is a disorder of structure or function in a human. We call these disorders ______?
What are diseases
100
a very small living thing, especially one that causes disease
What is a microbe or a pathogen
100
How are chemicals present in cigarette smoke able to enter the body and reach the brain?
First the chemicals are inhaled through the lungs. Next, the chemicals are transported through the circulatory system (red blood cells = transport!) until the blood reaches the brain.
200
This cell functions to protect the body against pathogens
What are white blood cells
200

these substances are found on the surface of all cells and receive and respond to nerve and hormone signals

What are receptor molecules

200
Give an example of a human detecting and reacting to stimuli in order to maintain homeostasis
Ex 1: Increased temperatures outside -> begin sweating to cool down and regulate body temperature. Ex 2: A person exercises and body temp increases -> blood vessels increase in diameter and body temp decreases Ex 3: Decreased temperature outside -> body begins shivering to conserve heat and maintain internal temp
200
the change in blood glucose levels over a period of time will increase and decrease depending on the amount of glycogen and insulin produced by the body. The body's attempt to maintain homeostasis by increasing and decreasing these chemicals is called:
What is dynamic equilibrium (a state of balance between continuing processes.)
200
Antibody molecules (from the immune system) and receptor molecules (from the nervous system) are similar because...
What is they have a specific shape that relates to their specific function (much like enzymes & the lock-and-key model).
300
Why do doctors introduce weakened microbes into the body of an organism?
What is to stimulate an immune system response--the immune system reacts and prepares the organism to fight future invasions by these microbes
300

The failure of which organ would be most likely to disrupt cellular communication?

What is the brain

300
Feedback interactions in the human body are important for this reason.
What is they maintain homeostasis and keep the internal body environment within its normal range.
300
substances that are found on cell surfaces and respond to nerve and hormone signals.
What are receptor molecules.
300
transports materials for energy release in body cells (like oxygen!)
What is the circulatory system
400
Why does an organ, such as a lung, used for transplant need to be tested for compatibility with the person who is receiving the organ?
What is because the person's immune system might attack the donated organ.
400
How do nerve cells communicate with muscle cells?
What is by having receptor sites along the muscle cell (see diagram).
400
In order for the body to maintain homeostasis, what needs to happen once glucose is broken down during cellular respiration?
What is energy needs to be released and wastes need to be removed.
400
this chemical is produced in the pancreas and helps maintain blood sugar levels throughout the day
What is insulin
400
Describe what the following chemicals are digested into: Starches -> Proteins ->
What is Starches -> simple sugars Proteins -> amino acids
500

How can vaccinations help to prevent the spread of disease, even in people who have not received the vaccination?

What is community immunity: Herd immunity

500
*NOT a nervous system question, sorry!* Explain why your pulse rate increases after exercise, and explain how a change in pulse rate helps to meet the needs of the body.
Pulse rate increases after exercise because the muscles need to exert more energy and need more oxygen to do so. By pumping blood at a faster rate, red blood cells can carry more O2 to the muscle cells, so cellular respiration can take place and the muscles have a continued supply of energy.
500
Which organ is used to produced enzymes that aid in breakdown of nutrients in order to maintain a balance of the digestive and endocrine systems?
What is the pancreas
500
a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
What is an antigen
500
A human goes to a baseball game and consumes a hot dog. What systems must interact to transfer the nutrients in the hot dog to the human muscle tissue?
What are the circulatory and digestive systems
