Cardiac Anatomy
This chamber of the heart pumps blood to the lungs.
What is the right ventricle?
This structure is known as the natural pacemaker of the heart.
What is the SA node?
These tiny air sacs are where gas exchange occurs.
What are alveoli?
The movement of air into the lungs is called this.
What is inspiration?
Swelling in the legs due to heart failure is called this.
What is edema?
This valve is located between the left atrium and left ventricle.
What is the mitral (bicuspid) valve?
This phase of the cardiac cycle is when the ventricles contract.
What is systole?
This muscle is primarily responsible for breathing.
What is the diaphragm?
The exchange of oxygen and carbon dioxide occurs by this process.
What is diffusion?
Chest pain caused by reduced blood flow to the heart muscle is called this.
What is Angina?
The heart is located in this area of the thoracic cavity.
What is the mediastinum?
Cardiac output is calculated by multiplying heart rate by this.
What is stroke volume?
This structure connects the larynx to the bronchi.
What is the trachea?
This gas increase acidity in the blood.
What is CO2 (Carbon Dioxide)?
This cardiovascular emergency occurs when blood flow to part of the heart muscle is blocked, causing tissue death.
What is myocardial infarction?
This blood vessel carries oxygenated blood away from the heart to the body.
What is the aorta?
This occurs when the heart cannot pump effectively to meet the body’s needs.
What is heart failure?
This membrane surrounds the lungs and reduces friction.
What is the pleural membrane?
This part of the brain sends signals to regulate breathing patterns.
What is the brainstem?
A patient presents with shortness of breath, and bilateral leg edema. These findings are most consistent with this cardiac condition.
What is right-sided heart failure?
