BP & EKG

Front

What does the T wave represent in an electrocardiogram (EKG)?

Back

The T wave represents ventricular repolarization.

Front

What role do proteins play in muscle contraction?

Back

Proteins in the plasma membrane allow potassium, sodium, and calcium to travel in and out of the cell during muscle contraction.

Front

What happens to the charge inside a cell during depolarization?

Back

The inside of the cell becomes less negative.

Front

What is the first positive wave in a normal cardiac cycle on an EKG?

Back

The P wave.

Front

How is a blood pressure of 140 mmHg/90 mmHg categorized?

Back

It is categorized as hypertension.

Front

What is the normal range for blood pressure?

Back

Typically, normal blood pressure is around 120/80 mmHg.

Front

What does the QRS complex represent in an EKG?

Back

The QRS complex represents ventricular depolarization.

Front

What is the significance of the P wave in an electrocardiogram?

Back

The P wave represents atrial depolarization.

Front

What is the function of calcium ions during muscle contraction?

Back

Calcium ions facilitate the interaction between actin and myosin, leading to muscle contraction.

Front

What is hypertension?

Back

Hypertension is a condition where blood pressure is consistently higher than normal, typically above 130/80 mmHg.
