Height of the blood column in the human body is more at feet than at the brain. As P=hρg, therefore the blood exerts more pressure at the feet than at the brain.

Assertion : The blood pressure in humans is greater at the feet than at the brain.
Reason : Pressure of liquid at any point is proportional to height, density of liquid and acceleration due to gravity.
The correct answer is option 'A': If both the assertion and reason are true and the reason is the correct explanation of the assertion.
Explanation:
Blood pressure is the force exerted by the blood against the walls of the blood vessels. It is an essential factor in maintaining blood flow and ensuring the delivery of oxygen and nutrients to all parts of the body. The blood pressure varies throughout the body depending on various factors.
The assertion states that the blood pressure in humans is greater at the feet than at the brain. This is true because of the effect of gravity on blood circulation. Blood pressure is influenced by the vertical distance between the heart and the specific body part.
The reason given for the assertion is that the pressure of liquid at any point is proportional to height, density of liquid, and acceleration due to gravity. This is known as Pascal's Law, which states that the pressure in a fluid is the same at all points at the same vertical height, regardless of the shape of the container.
In the case of blood circulation, the heart pumps blood against gravity to reach the brain. Due to the height difference between the heart and the brain, the blood pressure is higher in the arteries supplying blood to the brain compared to the veins carrying blood back to the heart. However, when blood flows down towards the feet, it encounters greater resistance from gravity, causing an increase in blood pressure in the lower extremities. Therefore, the blood pressure is indeed greater at the feet than at the brain.
In conclusion, the assertion is true and the reason is a valid explanation for it. The pressure of liquid in the human body, including blood, is influenced by height, density, and gravity, resulting in higher blood pressure at the feet compared to the brain.
Reason : Pressure of liquid at any point is proportional to height, density of liquid and acceleration due to gravity.
The correct answer is option 'A': If both the assertion and reason are true and the reason is the correct explanation of the assertion.
