The human respiratory system Flashcards
Correct the statement:
1. Respiration only happens in the cells in your lungs.
2. Respiration uses up energy.
3. Respiration happens in animals but not plants.
Here are the corrected statements:
1. Respiration happens inside all the cells in your body.
2. Respiration releases energy from food.
3. Respiration happens in all living things.
What are the 7 characteristics shared by all living things?
Respiration, Movement, Sensitivity, Excretion, Reproduction, Nutrition, and Growth.
What is respiration?
A series of chemical reactions that happen inside every living cell.
What is the kind of respiration that happens inside our cells?
Aerobic Respiration.
What is Aerobic Respiration?
Aerobic Respiration uses oxygen. The cells produce CO2 as a waste product.
What happens when you breath? What happens to the oxygen? Where is it taken?
The air around you contain oxygen. When you breath you take air into your lungs. Some of the oxygen from the air goes into your blood. The blood delivers the oxygen to every cell in your body, so that the cells use it for respiration. The blood collects waste carbon dioxide from the cells, and takes it back to the body.
What is the name of the system that the organs that help you take oxygen out of the air and get rid of carbon dioxide, make up?
Respiratory system.
Name the three tubes that air moves through, as it goes in and out of your lungs in the Respiratory system.
Trachea, bronchus (bronchi), and bronchiole.
Name the structures in order that air passes through as it moves into your lungs.
- Entrance to mouth/ Entrance to nose
- Pharynx
- Larynx
- Trachea
- Bronchus
- Bronchioles
- Alveoli/ Air sacs
What is the function of the Entrance to mouth/ Entrance to nose in the respiratory system?
Entrance through which air enters the body.
What is the Entrance to mouth and the Entrance to nose in the respiratory system?
Entrance to the Mouth: The entrance to the mouth is called the oral cavity or the oral opening. Air enters the respiratory system through the mouth when breathing through the mouth instead of the nose.
Entrance to the Nose: The entrance to the nose, which is the primary route for air intake in the respiratory system, is called the nostrils or nasal passages. Air enters the respiratory system through the nostrils (also known as the external nares) when breathing through the nose.
What is the function of the Pharynx in the respiratory system?
It directs air into the larynx.
The pharynx plays a crucial role in the respiratory and digestive systems by facilitating the movement of air, food, and liquids.
What is the Pharynx in the respiratory system?
The pharynx, also known as the throat, is a muscular tube. It serves as a passageway for both air and food.
What is the function of the Larynx in the respiratory system?
It contains the vocal cords that vibrate, producing sounds using the air and enabling us to speak. It directs air into the trachea and stops food from entering the trachea.
What is the Larynx in the respiratory system?
The larynx, commonly known as the voice box, is a crucial structure in the respiratory system responsible for various functions, including sound production, airway protection, and regulation of airflow during breathing. It is located in the neck region, just below the pharynx and above the trachea (windpipe).
What is the function of the Trachea in the respiratory system?
It is the windpipe and carries air deep into the body and out of the body.
What is the Trachea in the respiratory system?
The trachea, also known as the windpipe, is a vital part of the respiratory system that connects the larynx (voice box) to the bronchi of the lungs. It is a tubular structure made up of cartilage rings and smooth muscle, lined with mucous membrane.
What is the function of the Bronchus in the respiratory system?
They carry air into the lungs and distributes the air among the two lungs.
What is the Bronchus in the respiratory system?
The bronchi (singular: bronchus) are large airways or tubes in the respiratory system that branch off from the trachea (windpipe) and extend into the lungs.
What are the Bronchioles and what is the function of the Bronchioles in the respiratory system?
They are several smaller tubes whose structure allows air to reach deeper into the lungs.
What are the lungs and what is the function of the Lungs in the respiratory system?
They are two saccular thoracic organs in which the gas exchange and breathing occurs.
What are Air sacs/Alveoli in the respiratory system and what is their function?
Tiny microscopic holes or internal compartments that hold air and help facilitate gas exchange.
What is the function of the Ribs in the respiratory system?
Protect the lungs and heart and help in breathing. Various muscles such as intercostal muscles and diaphragm are also attached to the ribs.
What are the Ribs in the respiratory system?
The ribs are curved bones that form the rib cage, also known as the thoracic cage. This bony structure surrounds the chest cavity and provides protection to vital organs such as the heart and lungs.
