Respiratory Structure
Tube leading to either side of your lung
What is your bronchi
This muscle moves up and down changing the volume of air that moves in and out
What is the diaphragm?
Tubes that carry blood away from the heart.
What are arteries?
This heart chamber pumps blood into the pulmonary artery.
Right Ventricle
Cells that carry oxygen in blood?
What is red blood cells?
The flap of tissue that prevents food and water from entering the trachea.
What is the epiglottis?
Which has more oxygen: inhaled air or exhaled air?
What is inhaled air?
Ms. Magier carries a tub of books to the front of the class room--will her heart rate will increase or decrease?
What is increase?
What chemical is created due to increased CO2 that triggers your brain to send a signal to your diaphragm to increase your breathing rate?
carbonic acid
During this process, the diaphragm relaxes and moves up and the chest cavity contracts (moves in).
What is exhalation (exhale)?
What blood vessel does blood flow through after it leaves the lung?
What is the pulmonary vein?
How is the circulatory system dependent on the respiratory system?
respiratory is responsible for gas exchange while circulatory is transport the O2 and CO2
Tubes that branch out into the lungs off of the bronchi.
What are bronchioles?
Describe the difference between a vein and an artery.
Vein- return blood to the heart
Artery- transport blood away from the heart
What is the connection of O2 and CO2 with cellular respiration?
O2 is necessary to make ATP and CO2 is a waste product
What happens to the rib and diaphragm as you inhale?
ribs- expand
diaphragm- extend
What is the name of the air sacs where oxygen and CO2 are exchanged AND the blood vessels that cover them.
What are alveoli and capillaries?
The heart is made up of 4 chambers called
ventricles and atria
The heart pumps blood through these two circuits.
What are the pulmonary and systemic circuits?
FULL pathway of Oxygen starting at the nasal cavity and ending at the body cells. Include the blood vessel types!
nasal cavity - pharynx - larynx - trachea - bronchi - bronchioles - alveoli - pulmonary capillary - pulmonary vein - heart - systemic artery - systemic capillary
