Warmup: October 29, 2013

Is breathing the same as respiration? Why or why not?


Warmup october 29 2013

The words breathing and respiration are often used to mean the same thing. However, breathing is only one part of respiration. Respiration is the way the body gains and uses oxygen and gets rid of carbon dioxide.


Answers from homework

Answers from homework…

1. Lymph collects pathogens and dead cells

from body tissues. Lymphocytes in the lymph nodes, tonsils, and spleen attack and mark pathogens for destruction.

2. Plasma is pushed out of capillaries.

Lymph capillaries absorb lymph.

Lymph capillaries carry lymph to lymphatic

vessels.

Lymphatic vessels deliver lymph to veins in the neck


Answers continued

Answers continued…

3. blood plasma, dead cells, pathogens

4. Lymph tissue must be spread out to collect fluid from all areas of the body.


The respiration system

The Respiration System

  • Group of organs and structures that take in oxygen and release carbon dioxide

    Nose

    Throat

    Lungs

    Passageways to lungs


Warmup october 29 2013

Steps Air Flows to Lungs:

1. Air enters nose or mouth

2. Flows through pharynx (throat) 2 tubes, the esophagus leads to stomach and the other leads to lungs

3. Flows past larynx (vocal cords)

4. Trachea (windpipe)

5. Then, trachea splits into two branches called bronchi

6. Bronchus branches into smaller tubes called bronchioles

7. Bronchioles branches to form tiny sacs called alveoli in the lungs


Producing sound

Producing Sound

  • Muscles connected to the larynx control how much the vocal cords are stretched. When air flows between the vocal cords, the cords vibrate….these vibrations make sound.


How do you breathe

How Do You Breathe?

  • Lungs have no muscles

  • Diaphragm is dome-shaped muscle under lungs that contracts (moves down) when you inhale

  • Rib cage lifts up

  • Exhaling is opposite (diaphragm and rib muscles relax)


Respiratory disorders

Respiratory Disorders

  • Have trouble getting oxygen making them feel tired

  • Problems getting rid of carbon dioxide; therefore, building up in body and making them sick

  • Examples:

    • Asthma-causes bronchioles to narrow

    • Emphysema-alveoli are damaged

    • Severe Acute Respiratory Syndrome (SARS)-caused by a virus


Homework 10 29

Homework 10/29

1. What are three respiratory disorders?

2. What is cellular respiration?

3. How is respiration different from breathing?

4. The nose is the main way for air to get into and out of your body. How can a person still breathe if his or her nose is blocked?

5. How do vocal cords produce sound?

6. What are two ways that a respiratory disorder can make a person sick?
