Anatomy & Physiology 1 WS 24

Imagine you are a doctor explaining to a patient how their heart works. What is the function of the cardiac conduction system?

• Deliver the electrical signals to their final destination

• An ultrasound of the heart

• Intrinsic conduction system; has two “nodes” that set the pace of the heartbeat

• The first major wave seen on the ECG

What is the SA Node?

• Deliver the electrical signals to their final destination

• A small group of cells located in the upper portion of the right atrium’s wall; heart's main pacemaker

• The amount (volume) of blood pumped with each heartbeat

• The last wave in the ECG

What is the role of Purkinje fibers in Benjamin's heart during a medical examination?

• Deliver the electrical signals to their final destination

• An ultrasound of the heart

• The recording that is produced from the electrical impulses transmitted through the heart

• The first major wave seen on the ECG

Luna is studying the human heart in her biology class. She learns about various diagnostic tools used in cardiology. What does an electrocardiogram (ECG) record?

• The amount (volume) of blood pumped with each heartbeat

• The recording that is produced from the electrical impulses transmitted through the heart

• The last wave in the ECG

• An ultrasound of the heart

What is the P Wave in an ECG?

• The first major wave seen on the ECG

• The last wave in the ECG

• An ultrasound of the heart

• The amount (volume) of blood pumped with each heartbeat

Aiden is studying the electrical activity of the heart in his biology class. He learns about different waves in an ECG. What is the QRS complex?

• The last wave in the ECG

• The first major wave seen on the ECG

• The second large wave seen in a typical ECG

• The recording that is produced from the electrical impulses transmitted through the heart

What is the T wave in an ECG?

• The last wave in the ECG

• The first major wave seen on the ECG

• An ultrasound of the heart

• The amount (volume) of blood pumped with each heartbeat

Abigail is studying the human body and she wants to understand how the heart functions. She learns about a term that describes the amount of blood pumped by the heart in one minute. What is this term?

• Cardiac output

• An ultrasound of the heart

• The recording that is produced from the electrical impulses transmitted through the heart

• Deliver the electrical signals to their final destination

Elijah is learning about the human heart in his biology class. His teacher asks, "What is stroke volume?"

• The amount (volume) of blood pumped with each heartbeat

• An ultrasound of the heart

• The recording that is produced from the electrical impulses transmitted through the heart

• Deliver the electrical signals to their final destination

Harper went to the doctor for a routine check-up. The doctor decided to perform an echocardiogram. What is an echocardiogram?

• An ultrasound of the heart

• The recording that is produced from the electrical impulses transmitted through the heart

• The first major wave seen on the ECG

• The last wave in the ECG
