In which one of the following pairs, two terms represent the same thin...
Explanation:
In the given options, the correct pair in which two terms represent the same thing is option C: Mitral valve - bicuspid valve.
Understanding the Terms:
1. Mitral Valve: The mitral valve is one of the four valves present in the human heart. It is located between the left atrium and the left ventricle. Its main function is to prevent the backflow of blood from the left ventricle to the left atrium during contraction of the heart.
2. Bicuspid Valve: The bicuspid valve is another name for the mitral valve. It is called bicuspid because it consists of two cusps or leaflets. The term "bicuspid" refers to the presence of two flaps or leaflets in this valve.
Explanation of the Answer:
The terms "mitral valve" and "bicuspid valve" represent the same structure in the heart. Both terms are used interchangeably to refer to the valve present between the left atrium and the left ventricle. The use of these terms may vary in different medical contexts or textbooks, but they refer to the same structure.
The other options in the question do not represent the same thing:
a) Lymphocyte - leucocyte: Lymphocytes and leucocytes are different types of white blood cells. While lymphocytes are a specific type of white blood cell involved in immune responses, leucocyte is a general term that refers to all types of white blood cells.
b) Plasma - serum: Plasma and serum are two different components of blood. Plasma is the liquid component of blood that contains various proteins, hormones, and other substances. Serum, on the other hand, is the fluid portion of blood that remains after clotting. It does not contain clotting factors present in plasma.
d) Atrioventricular node - pacemaker: The atrioventricular node (AV node) and pacemaker are two separate components of the heart's electrical system. The AV node is a specialized group of cells located between the atria and ventricles, responsible for conducting electrical signals. The pacemaker, also known as the sinoatrial node (SA node), is another group of specialized cells that initiate the electrical impulses in the heart and regulates the heart rate.
