Nervous system
What is the main function of the central nervous system?
What is to process sensory information and control the response?
What gland produces insulin?
What is the pancreas?
What is the main function of the circulatory system?
What is transporting oxygen, nutrients, hormones, and waste throughout the body.
What gas is exchanged in the alveoli?
What is oxygen and carbon dioxide?
What is the maintenance of a stable internal environment
Which part of the brain controls the heart rate
What is the medulla oblongata
What is the main function of adrenaline in the fight-or-flight response?
What is to increase heart rate, blood pressure, and energy availability for immediate physical action?
What type of blood vessel carries blood away from the heart?
What are arteries.
What muscle helps control breathing?
What is the diaphragm
Give an example of a homeostatic process in the human body?
What is the regulation of body temperature, blood glucose, or blood pH?
What is the role of a sensory neuron?
What is to carry information from sensory receptors to the central nervous system?
Name two hormones released by the pituitary gland.
What are growth hormones and antidiuretic hormone?
How does the circulatory system support cellular respiration?
What is by delivering oxygen and glucose needed for ATP production
How does the respiratory system maintain pH balance in the blood?
What is by regulating carbon dioxide levels
How do the nervous and endocrine systems work together to regulate blood temperature?
What is the hypothalamus detects temperature changes and signals sweat glands or shivering muscles via hormones and nerve impulses.
What is the function of the hypothalamus in homeostasis?
What is regulating body temperature, thirst, hunger, and linking the nervous system to the endocrine system?
How do negative feedback loops maintain hormone levels?
What are loops where rising hormone levels inhibit further hormone release, maintaining balance?
Explain the role of the sinoatrial node in heart function.
What is it generates electrical impulses that initiate the heartbeat.
Describe how gas exchange is affected during exercise.
What is breathing rate and depth increase to meet the body's higher oxygen demand and get rid of carbon dioxide.
Describe the feedback mechanism that regulates blood glucose levels.
What is when blood glucose rises, the pancreas releases insulin.
Explain how a reflex arc integrates sensory and motor responses.
What is a reflex arc that includes a sensory neuron, an interneuron in the spinal cord, and a motor neuron, enabling a fast, involuntary response?
Compare and contrast the nervous and endocrine systems in terms of signal transmission and duration.
What is the nervous system uses electrical signals for fast responses, while the endocrine system uses hormones for slower long long-lasting regulation.
Describe how the circulatory and endocrine systems interact to regulate blood pressure.
What is hormones like adrenaline increase heart rate and blood pressure, while baroreceptors in blood vessels send signals to regulate it
Wxplain how the respiratory and circulatory systems work together to deliver oxygen to tissues.
Analyze how at least three body systems integrate during a stress situation.
What is the nervous system detects stress, signals the endocrine system to release adrenaline. and the circulatory and respiratory systems respond to support the body
