Consider the following statements regarding blood pressure:1. It is the pressure exerted by the blood on the walls of any vessel.2. It decreases in the arteries as the distance from the heart increases.3. It is lower in the capillaries than in the arteries.4. It is usually lower in women than in men.Choose the correct statements.
Correct answer: D. 1, 2, 3 and 4 are correct.
- A. 1, 2 and 3 are correct.
- B. 2, 3 and 4 are correct.
- C. 1 and 4 are correct.
- D. 1, 2, 3 and 4 are correct.
Explanation
Blood pressure (BP) is the pressure of circulating blood on the walls of blood vessels. In arteries near to heart is larger than the distant ones as pushing by heart decreases. It is lower in the capillaries than in the arteries because the velocity of flow is increased with the decrease in diameter and vice versa. It is usually lower in women than in men as men have more hypertension than women. So the correct option is '1, 2, 3 and 4 are correct'.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
