Stress & Stressors
Clue: This is anything that causes a change or challenge that an organism must respond to.
Answer: What is a stressor?
Clue: This is the process of keeping internal conditions relatively stable even when the environment changes.
Answer: What is homeostasis?
Clue: In a feedback loop, this is the change that causes the organism to respond.
Answer: What is a stimulus?
Clue: A group of organs that work together to perform important jobs in the body is called this.
Answer: What is an organ system?
Clue: The ENDOCRINE SYSTEM sends out Cortisol during stressful times. These chemical messengers travel through the body and affect the activity of cells and organs.
What are these chemicals called?
What are Hormones
Clue: This is the body's response to a stressor or change in the environment.
Answer: What is a stress response?
Clue: Your body tries to keep your internal temperature near this target value.
Answer: What is a set-point?
Clue: In a feedback loop, the body part that detects a stimulus is called the...
Give an Example of one that we have studied in class
Answer: What is the Receptor.
The pancreas is the receptor in the glucose/blood sugar model.
Clue: The heart is a structure in the circulatory system. What is the main structure it transports?
Answer: What is blood?
Clue: This organ system uses electrical signals and unique specialized cells to help the body communicate and respond quickly to changes.
Answer: What is the nervous system?
Clue: A loud fire alarm suddenly goes off while you are sitting in class. The fire alarm is an example of this.
Answer: What is a stressor?
Clue: You become too hot while exercising, so your body begins to sweat. Sweating helps your body return toward your set point in this Process.
Answer: What is homeostasis?
Clue: Put these steps in the correct order:
Stimulus → Effector → Receptor → Control Center
Answer:
Stimulus → Receptor → Control Center → Effector
Clue: What is the difference between Structure and Function in biology?
Give an example.
Structure = How it's made
Function = The purpose it serves.
Example: Having 5 fingers that use muscle and bend allow us to grip things in different ways.
This branch of the nervous system is associated with the body's "fight-or-flight" response during stressful situations.
Answer: What is the sympathetic nervous system?
Clue: A student is worried about an upcoming test every day for several weeks. This type of stress lasts for an extended period of time.
Answer: What is chronic stress?
Clue: A person's body temperature rises above its normal level. The body responds by sweating and increasing blood flow to the skin. What is the Stimulus and Effector in this Scenario?
What is Rise in Temperature and Sweat glands.
Clue: A person's body temperature gets too high. Receptors detect the change, the brain processes the information, and sweat glands produce sweat. What is the effector in this scenario and how does it differ from that of frogs?
Answer: What are the sweat glands.
Frogs do not have sweat glands in their skin and must rely on other methods to regulate their body temperature.
Clue: The brain is an important structure in the human body. One of its functions is to process information and help coordinate the body's response to changes.
What Organ system is it a part of AND name two structures that make it up.
Answer: What is the Nervous system
Structures: Brain, Spinal Cord, Nerves (Neurons)
Clue: This branch of the nervous system helps the body "rest and digest" after a stressful situation.
Answer: What is the parasympathetic nervous system?
Clue: Explain the difference between a stressor and a stress response AND give an example.
Answer: What is a stressor causes a change while the stress response is how the organism reacts to that change.
Example: A loud noise is the stressor; increased heart rate is the response.
Clue: A student goes outside on a cold day. Their body temperature begins to decrease, so their body shivers to produce heat. Explain how this response helps maintain homeostasis.
Answer: What is Shivering produces heat, helping the body temperature move back toward its set-point, maintaining homeostasis.
Clue: A person becomes dehydrated. Receptors in the body detect that the body has too little water. The brain processes the information, and the kidneys conserve more water. Identify the receptor, control center, and effector.
Answer:
Clue: During exercise, the respiratory and circulatory systems work together. Explain one way these two organ systems help your cells.
Answer: What is The respiratory system brings oxygen into the body, while the circulatory system transports oxygen to cells.
Clue: A student hears a sudden loud noise. Their heart rate increases and they become more alert. After the danger passes, their heart rate begins returning toward normal. Which two nervous system branches are involved, and what does each do?
Answer: What is..
