Question

Which of these definitions have been paired with the correct type of cell?

Blood cells are elongated cells that can contract.
Neurons are cells that conduct electrical impulses.
Epithelial cells are cells that carry oxygen through the body.
Muscle cells are components of blood.

Answer 1

Only the neuron item is correct.

Corrections:
- Blood cells: cells found in blood (erythrocytes carry oxygen, leukocytes fight infection, platelets help clotting).
- Epithelial cells: cells that line surfaces and cavities; they protect, secrete, and absorb.
- Muscle cells: elongated, contractile cells that make up muscle tissue.
