Q1 SCIENCE RESPIRATORY AND CIRCULATORY

• A network of organs and tissues within the body. It is responsible for the process of breathing, allowing the intake of oxygen and removal of carbon dioxide. Its primary function is to absorb oxygen from the air and transport it to the body’s organs, enabling them to function properly. 

• The organs of the ______ work together to facilitate the exchange of gases between the body and the environment.

• CIRCULATORY SYSTEM

• NERVOUS SYSTEM

• RESPIRATORY SYSTEM

• DIGESTIVE SYSTEM

PARTS OF THE RESPIRATORY SYSTEM (FLASHCARDS ONLY)

• >Nose/nasal cavity
  > Nasal passages
  > Pharynx/throat
  > Larynx
  > Trachea
  > Bronchi
  > Bronchioles
  > Alveoli

• -

• A network of smaller branches leading from the bronchi into the lung tissue and ultimately to air sacs. It is the hair like tubes that connect to the alveoli

• BRONCHI

• DIAPHRAGM

• PHARYNX

• BRONCHIOLES

The functional respiratory units in the lung where gases are exchanged.

• LARYNX

• PHARYNX

• ALVEOLI

• DIAPHRAGM

• It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. When you inhale, the ___ muscle contracts. When you exhale, the ________ muscle relaxes.

• PHARYNX

• NOSE/NASAL CAVITY

• TRACHEA

• DIAPHRAGM

• (THROAT) The passageway for air, leads to trachea.

• NOSE/NASAL CAVITY

• PHARYNX

• TRACHEA

• BRONCHI

• Warms, moistens, and filters air as it is inhaled.

• TRACHEA

• LARYNX

• ALVEOLI

• NOSE/NASAL CAVITY

• Two branches at the end of the trachea, each lead to a lung. (2 branching tubes)

• ALVEOLI

• BRONCHIOLES

• BRONCHI

• DIAPHRAGM

• Keeps the windpipe “open”, the trachea is lined with fine hairs called cilia which filters air before it reaches the lungs. Empty tube that serves as passageway of air into the lungs.

• BRONCHIOLES

• ALVEOLI

• NOSE/NASAL CAVITY

• TRACHEA

CIRCULATION =

• LINKED TO BREATHING

• TRANSPORTATION OR MOVEMENT IN CIRCLES
