How do lungs work?

1.) Define resperation
2.) Two types of respiration
3.) What is function of respiratory system
4.) Parts of respiratory system
5.) Gas involve in gas exchange during respiration​


Sagot :

When you inhale (breath in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, transfers from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.

1, The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

2. The two types of respiration are aerobic respiration ( it is a process that uses oxygen) and anaerobic respiration ( it is a process that doesn't use oxygen).

3. The respiratory system's main job is to move fresh air into your body while removing waste gases. Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide.

4. Nose.

Mouth.

Throat (pharynx)

Voice box (larynx)

Windpipe (trachea)

Airways (bronchi)

Lungs.

5. During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Answer:

1) inhale

2) Aerobics respiration and anaerobic respiration

3) Delivers oxygen to the cells of the body

4 & 5 just read the description

Explanation:

1.) To breathe in (inhale), you use the muscles of your rib cage – especially the major muscle, the diaphragm. To breathe out (exhale), your diaphragm and rib cage muscles relax. This naturally lets the air out of your lungs.

2) Aerobics respiration (it is the process uses on oxygen) and Anearobic respiration (it is a process that doesn't use oxygen)

3)Delivers oxygen to the cells of the body.

Removing wasted gasses, including carbon dioxide, from the body when you exhale

4)mouth and nose:

Openings that pull air from outside your body into your respiratory system.

Sinuses:

Hollow areas between the bones in your head that help regulate the temperature and humidity of the air you inhale.

Pharynx (throat):

Tube that delivers air from your mouth and nose to the trachea (windpipe).

Trachea:

Passage connecting your throat and lungs.

Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung.

Lungs:

Two organs that remove oxygen from the air and pass it into your blood.

5) During gas exchange oxygen moves from the lungs to the bloodstream.At the same time

carbon dioxide poses from the blood to the lungs

This happen to the lungs between to aveoli amd a network of tiny blood vessels called capillaries, which located in the walls of aveoli
