The correct answer is C. Heart.
The heart is a muscular organ that pumps blood throughout the body. It is located in the chest, between the lungs. The heart has four chambers: two atria and two ventricles. The atria are the upper chambers, and the ventricles are the lower chambers. The heart pumps blood through the body in two circuits: the pulmonary circuit and the systemic circuit.
The pulmonary circuit carries blood from the heart to the lungs. The blood picks up oxygen in the lungs and releases carbon dioxide. The systemic circuit carries blood from the heart to the rest of the body. The blood delivers oxygen and nutrients to the body tissues and removes carbon dioxide and waste products.
The heart is a vital organ, and its function is essential for life. If the heart stops beating, death will occur within minutes.
The other options are incorrect because they are not organs that pump blood.
- Neck is a part of the body that connects the head to the torso.
- Testis is a male reproductive organ that produces sperm.
- Nose is a sensory organ that is used for smelling.
