Blood pressure is defined as the force with which blood

Options

A. comes out of the atrium
B. is pushed to the legs
C. pushes against wall of blood vessels
D. comes out of the ventricle

Answer

**Step-by-Step Solution:**

1. **Understanding Blood Pressure**: Blood pressure is essentially the force exerted by circulating blood on the walls of blood vessels. It is a vital sign that indicates how well the heart is functioning and how effectively blood is being circulated throughout the body.

2. **Identifying the Correct Definition**: Among the options provided, we need to identify which one correctly describes blood pressure. The options are:
- A) It comes out of the atrium
- B) Is pushed to the legs
- C) Pushes against the wall of blood vessels
- D) Comes out of the ventricle

3. **Analyzing the Options**:
- Option A (comes out of the atrium) is incorrect because blood pressure is not defined by the movement of blood from the atrium.
- Option B (is pushed to the legs) is also incorrect as it is too specific and does not encompass the general definition of blood pressure.
- Option C (pushes against the wall of blood vessels) accurately describes blood pressure as it refers to the force exerted by blood on the walls of the blood vessels.
- Option D (comes out of the ventricle) is partially correct but does not fully define blood pressure, as it does not mention the walls of the blood vessels.

4. **Conclusion**: The correct definition of blood pressure is that it is the force with which blood pushes against the walls of blood vessels.

5. **Normal Blood Pressure Values**: It is important to note that blood pressure is measured in millimeters of mercury (mm Hg) and is typically expressed as two numbers: systolic pressure (when the heart contracts) over diastolic pressure (when the heart is at rest). A normal blood pressure reading is around 120/80 mm Hg.

**Final Answer**: Blood pressure is defined as the force with which blood pushes against the walls of blood vessels.
