Nervous System
Definition of the Nervous System? (One of the three functions)
- Controls and coordinates the body
- Helps with thinking, movement, and reactions
- Uses neurons to send messages
Definition of the Respiratory System?
How your body breathes and gets oxygen
● Nose/Nasal cavity
● Pharynx (throat)
● Larynx (voice box)
● Trachea (windpipe)
● Lungs
What is one of the three things that can cause respiratory disease?
Genetics, Infections, Environmental Factors
These two things are responsible for sending/receiving Signals in the Nervous System
Dendrites, Axons
Sort these three parts of the nervous system with the correct branch of the nervous system(CNS or PNS)
Brain, Spinal Cord, Nerves outside CNS
Brain and Spinal Cord = CNS
Nerves outside CNS = PNS
What is ONE main function of the Respiratory System?
● Brings oxygen (O2) into the body
● Removes carbon dioxide (CO2)
● Helps cells produce energy
Cerebrum, Cerebellum, Brain Stem
1. Pneumonia is an example of this type of disease
2. Asthma is an example of this type of disease
3. COPD is an example of this type of disease
1. Infectious
2. Chronic
3. Lifestyle-Related
Tiny air sacs of the lungs
Alveoli
These are the nerve cells that carry messages
Neurons
During gas exchange in the alveoli, ______ enters blood, and ______ leaves blood
There are two "Nervous Systems" in the body... What are they? (I will accept abbreviations, but I will give DOUBLE POINTS) if you tell me the full name
Peripheral Nervous System(PNS)
What are two of the four prevention tips for avoiding respiratory disease?
- Avoid smoking and secondhand smoke
- Exercise regularly
-Wash hands to prevent infections
- Stay up to date with vaccines
Involved in inhalation and exhalation
Diaphragm
Which of these is responsible for Breathing and Heartbeat in the brain?
A) Brain Stem
B) Cerebrum
C) Cerebellum
A) Brain Stem
What happens to the diaphragm when you...
1. Inhale?
2. Exhale?
1. Diaphragm moves down(air in)
2. Diaphragm moves up(air out)
Put these nerve types in order of their function...
Nerve Types: Sensory Nerves, Relay Neurons, Motor Nerves
Functions: Carry Commands to Muscles, Connect Neurons in CNS, Carry Info to Brain
Sensory Nerves carry info to brain
Motor Nerves Carry Commands to Muscles
Relay Neurons connect neurons in CNS
True or False: Every single respiratory disease that exists is contagious(can spread from one person to another)
False(Some are non-contagious, i.e. Asthma cannot spread like the Flu can)
An electrical Message
Impulse
These are fast responses that are controlled by your spinal cord
Reflexes
What is one health connection?
(There are three each that we have in our notes)
Why It Matters: Provides energy for the body, Works with circulatory system, Essential for survival
Health Connections: Exercise improves lung function, Smoking/vaping damages lungs, Asthma affects breathing
Two Part Question!
1. What is the difference between Somatic and Autonomic?
2. What is the difference between Sympathetic and parasympathetic?
1. Voluntary Actions(Somatic), Involuntary Actions(Autonomic)
2. Sympathetic = speeds up body, parasympathetic = calms body
What does COPD stand for?
Chronic Obstructive Pulmonary Disease
This causes a reaction
Stimulus
