Respiratory System
What is: Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen (chemical process).
Cellular Respiration
What is the structure in the throat that contains the vocal cords.
Larynx
What is a large, flat muscle at the bottom of the chest cavity that helps with breathing.
Diaphragm
What brings oxygen-rich blood from the left ventricle to the body
Aorta
What prevents blood from flowing back into the right atrium after it has entered the right ventricle
Tricuspid Valve
What is a process of gas exchange which involves the release of carbon dioxide and uptake of oxygen between the lungs and the environment (physical process).
Respiration
What is Larger air tubes that direct air into the lungs. They have cartilage rings to provide support.
Bronchi
What brings oxygen-poor blood to the right or left lung
Pulmonary Arteries
What prevents blood from flowing back into the right ventricle after it has entered the pulmonary artery
Pulmonary Valve
What is a site for gasses entering and exiting the body. Helps to warm, moisten, and filter the air.
Nasal Cavity
What are short, hairlike projections that produce movement. Cilia line the upper and lower respiratory system.
Cilia
What prevents blood from flowing back into the left ventricle after it has entered the aorta
Aortic Valve
This is a large vein that brings oxygen-poor blood from the upper part of the body to the right atrium
Superior Vena Cava
what is the passageway for air and food to enter the body.
Pharynx
What are tiny air tubes that branch into each of the lungs that are so tiny that they do not cartilage rings for support.
Bronchioles
This prevents blood from flowing back into the left atrium after it has entered the left ventricle
Mitral Valve
Veins bring blood TO the what?
Heart
What is a small flap of cartilage which closes the trachea while food goes down the esophagus.
Epiglottis
What are tiny air sacs at the end of a bronchiole in the lungs that provide surface area for gas exchange to occur.
Alveoli
The vein that brings oxygen-poor blood from the lower part of the body to the right atrium
Inferior Vena Cava
Arteries carry blood AWAY from the what?
Heart
