A#136: Quizizz Respiratory System Quizs

Respiration

• The process of gas exchange – the release of CO2 and the uptake of O2 between the lungs and the environment.

• The process of breaking down glucose to produce energy without oxygen.

• The process of converting sunlight into chemical energy in plants.

• The process of filtering waste products from the blood in the kidneys.

Pleural Cavity

• Two sacs that surround the lungs inside the chest cavity.

• A single large cavity that contains the heart.

• A space filled with air between the lungs.

• The area where the diaphragm meets the lungs.

Epiglottis

• A flap of tissue that covers the entrance to the trachea when you swallow.

• A muscle that helps in the movement of the jaw.

• A type of cartilage found in the ear.

• A gland that produces saliva.

Gas Exchange (Muscles)

• Oxygen diffuses from high concentration in the blood to low concentration in the muscles

• Oxygen diffuses from low concentration in the blood to high concentration in the muscles

• CO2 diffuses from low concentration in the muscles to high concentration in the blood

• CO2 diffuses from high concentration in the blood to low concentration in the muscles

Gas Exchange (Lungs)

• Oxygen diffuses from high concentration in the alveoli to low concentration in the blood

• Oxygen diffuses from low concentration in the alveoli to high concentration in the blood

• CO2 diffuses from low concentration in the blood to high concentration in the alveoli

• CO2 diffuses from high concentration in the alveoli to low concentration in the blood

Alveoli

• Tiny air sacs at the end of the bronchioles clustered into bunches and surrounded by capillaries

• Large tubes that carry air to the lungs

• Muscles that help in the process of breathing

• Cells that produce mucus in the respiratory system

Inhalation

• The diaphragm contracts and air rushes into the lungs.

• The diaphragm relaxes and air is expelled from the lungs.

• The lungs fill with fluid and oxygen is absorbed.

• The diaphragm contracts and air is pushed out of the lungs.

Bronchioles

• Small subdivisions of the bronchi

• Large air passages leading to the lungs

• Tiny air sacs for gas exchange

• Muscles that control airflow in the lungs

Bronchi

• 2 large passageways in the chest cavity that lead into the lungs

• Small air sacs in the lungs where gas exchange occurs

• Muscles that control the movement of air in and out of the lungs

• The main airway that connects the throat to the lungs

Diaphragm

• A large, flat muscle at the bottom of the chest cavity.

• A small, round muscle that helps in digestion.

• A muscle that separates the abdominal and thoracic cavities.

• A muscle involved in the movement of the arms.
