_____ moving _____ the alveolus from blood.
Carbon dioxide moving into the alveolus from blood.
False-The blood picks up oxygen and glucose, delivering them to needy cells.
Structures of the respiratory system include the two passages that direct air into the lungs.
Bronchi
What body part is known as the windpipe of the body?
Trachea
Where do gases move between?
Gases move between the alveoli and the blood.
What happens at the same time when air enters the alveoli, and oxygen enters the bloodstream?
Carbon dioxide and water pass from the blood into the alveoli.
The digestive system provides glucose used in cellular respiration.
True or False
True.
The body part that you use to taste with and moistens the air you breathe.
Nose
Oxygen moves from alveolus into the bloodstream, right?
How do low and high air pressure relate to the breathing process(exchange of gases)?
As the chest moves upward, it expands, lowering the air pressure in the lungs, and moving air in. When exhaling, the muscles relax, and the chest lowers, air pressure increases, forcing air out.
The respiratory system brings air with oxygen into the body and removes carbon dioxide and water as waste.
True or False
True
The structure of the respiratory system includes tiny, thin-walled sacs of lung tissue, where gases are moved between air and blood.
Alveoli
Does a stronger respiratory system remove waste more efficiently and receive more oxygen?
Most definitely!
What is the ¨trash¨ we breathe out?
When exhaling, carbon dioxide and excess water are removed from the body.
Two systems in the body that work together to transport all the gases to all parts of the body.
The circulatory and respiratory systems work together. The respiratory system brings in oxygen and the circulatory system moves that oxygen in the blood to all cells in the body. The blood also carries the carbon dioxide from the respiratory system as waste to the lungs to be exhaled.
What are the two main functions of the respiratory system?
Short Answer
The two main functions of the respiratory system are removing carbon dioxide and water from the body, and taking in oxygen from the air to the lungs.
The respiratory system mainly works with the excretory system, right?
Nope, the respiratory system mainly works with the circulatory system, which transports the oxygen from the lungs to all of the body´s cells while removing carbon dioxide as waste.
Explain the process in which gases are exchanged, in and out of the body.
By inhaling and exhaling, your body exchanges carbon dioxide for oxygen, carbon dioxide being the waste product. The oxygen inhaled moves into the bloodstream, while carbon dioxide moves from the blood to the lungs to be exhaled. This process occurs by diffusion.
During gas exchange in the lungs, oxygen moves from the alveoli into the blood through diffusion because there is a higher concentration of oxygen in the air sacs than in the blood.
True or False
True
The muscle is mainly responsible for breathing(gas exchange).
The diaphragm is a muscle that contracts to take in air into the lungs and relaxes to force air out of the body.
What are the five main structures of the respiratory system?
Short Answer
The five main structures of the respiratory system are the lungs, nose, trachea, bronchi, and alveoli.
Breathing and Cellular Respiration are practically the same, right?
Cellular respiration is the process by which cells break down glucose for energy, requiring oxygen and producing carbon dioxide as a waste product. Breathing is just the exchange of gases in the body.
