1. describe what causes your pulse?

Explanation:

Step1: Calculate heart - beats per day

There are 60 minutes in an hour and 24 hours in a day.
The number of minutes in a day is \(60\times24 = 1440\) minutes.
If the heart beats 70 times per minute, then the number of heart - beats per day is \(70\times1440=100800\) times.

Step2: Calculate heart - beats per year

Assume a non - leap year has 365 days.
Since the heart beats 100800 times per day, the number of heart - beats per year is \(100800\times365 = 36792000\) times.

Step3: Answer question 3

From the text: "The left ventricle receives blood from the left atrium. The right atrium receives blood from the body."

Step4: Answer question 4

From the text: "Your pulse is caused by the pumping of blood into your arteries."

Answer:

1. A person's heart beats 100800 times in one day and 36792000 times in one year.
2. The left ventricle receives blood from the left atrium. The right atrium receives blood from the body.
3. Your pulse is caused by the pumping of blood into your arteries.
