Muscle
This muscle type is voluntary and attached to bones.
What is skeletal muscle?
These chambers receive blood.
What are atrium?
This vessel carries blood from the heart to the lungs.
What is the pulmonary artery?
This wave represents atrial contraction.
What is the P wave?
This is where gas exchange occurs.
What are alveoli?
This muscle type is found in the heart and pumps blood.
What is cardiac muscle?
This chamber pumps blood to the body.
What is the left ventricle?
This vessel carries oxygenated blood to the body.
What is the aorta?
This wave represents ventricular contraction.
What is the QRS complex?
This gas enters the blood in the lungs.
What is oxygen?
This muscle type is found in organs like the intestines and blood vessels.
What is smooth muscle?
These structures prevent backflow of blood.
What are valves?
This color represents oxygen-poor blood in diagrams.
What is blue?
This structure is the natural pacemaker.
What is the SA node?
This muscle helps pull air into the lungs.
What is the diaphragm?
This muscle type has striations and multiple nuclei.
What is skeletal muscle?
This chamber receives deoxygenated blood from the body.
What is the right atrium?
This structure carries oxygenated blood from lungs to heart.
What are pulmonary veins?
This node delays the signal so atria contract first.
What is the AV node?
This is the correct path of air after the trachea.
What are bronchi → bronchioles → alveoli?
This muscle type is involuntary and has intercalated discs.
What is cardiac muscle?
This valve is located between the left atrium and left ventricle.
What is the bicuspid (mitral) valve?
This is the correct order after blood leaves the right ventricle.
What is pulmonary valve → pulmonary artery → lungs?
This is the correct order of electrical conduction.
What is SA node → AV node → Bundle of His → Bundle branches → Purkinje fibers?
This type of circulation moves blood between the heart and lungs.
What is pulmonary circulation?
