Statement 1: Human heart is divided into four chambers.
Statement 2: The upper two chambers are called Ventricles and lower ones are called Atrium.
Statement 3: Pulse rate is due to the muscles of the heart contracting and relaxing rhythmically.
Explanation:
The human heart is a vital organ responsible for pumping oxygenated blood to various parts of the body. It consists of four chambers, each with a specific function. Let's analyze each statement to determine their correctness.
Statement 1: Human heart is divided into four chambers.
This statement is correct. The human heart is divided into four chambers: two upper chambers called atria (singular: atrium) and two lower chambers called ventricles. The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs. The chambers are separated by valves that control the flow of blood.
Statement 2: The upper two chambers are called Ventricles and the lower ones are called Atrium.
This statement is incorrect. The upper two chambers of the heart are called atria (singular: atrium), while the lower two chambers are called ventricles. The atria receive blood from various parts of the body and lungs, and then contract to push the blood into the ventricles. The ventricles, in turn, contract to pump the blood out of the heart to the rest of the body.
Statement 3: Pulse rate is due to the muscles of the heart contracting and relaxing rhythmically.
This statement is correct. The pulse rate is the number of times the heart contracts and relaxes per minute. It is determined by the rhythmic contraction and relaxation of the heart muscles, which is known as the cardiac cycle. The contraction of the heart muscles (systole) pushes blood out of the heart, while the relaxation (diastole) allows the chambers to refill with blood. This rhythmic activity creates the pulse that can be felt in various parts of the body, such as the wrist or neck.
Conclusion:
From the analysis, we can conclude that Statement 1 and Statement 3 are correct, while Statement 2 is incorrect. Therefore, the correct answer is option 'A' - 1 only.
Statement 2: The upper two chambers are called Ventricles and lower ones are called Atrium.
Statement 3: Pulse rate is due to the muscles of the heart contracting and relaxing rhythmically.

Option (a) is the correct answer.
The heart is an organ which beats continuously to act as a pump for the transport of blood, which carries other substances with it.
Statement 1 is correct. Heart is divided into 4 chambers, two upper and two lower.
Statement 2 is incorrect. The two upper chambers are called the atria (singular: atrium) and the two lower chambers are called the ventricles. The partition between the chambers helps to avoid mixing up of blood rich in oxygen with the blood rich in carbon dioxide.
Statement 3 is incorrect. The walls of the chambers of the heart are made up of muscles. These muscles contract and relax rhythmically. This rhythmic contraction followed by its relaxation constitutes a heartbeat. While the pulse is due to the blood flowing in the arteries. The number of beats per minute is called the pulse rate. A resting person, usually has a pulse rate between 72 and 80 beats per minute.
