Question

Organs of the circulatory system are : \[ \begin{aligned} A.&\ \text{Arteries} B.&\ \text{Capillaries} C.&\ \text{Esophagus} D.&\ \text{Epiglottis} E.&\ \text{Veins} \end{aligned} \] Choose the most appropriate answer from the options given below :

• A. A, E, C only
• B. A, D, B only
• C. A, B, E only
• D. B, D, C only

Concept: The circulatory system is responsible for transporting blood, oxygen, nutrients, and waste materials throughout the body. Its major components include:
• Heart
• Blood
• Blood vessels The main types of blood vessels are: \[ \text{Arteries, Veins, and Capillaries} \] Esophagus belongs to the digestive system, while epiglottis is associated with the respiratory and digestive pathways.

Step 1: Identify components of the circulatory system.
Among the given options: \[ \text{Arteries, Capillaries, and Veins} \] are blood vessels of the circulatory system.

Step 2: Eliminate unrelated organs.

• Esophagus is part of the digestive system.
• Epiglottis helps prevent food from entering the windpipe.

Step 3: Choose the correct combination.
Thus, the correct set is: \[ A, B, E \] Hence, the correct answer is: \[ \boxed{(C)\ A, B, E\ \text{only}} \]
