It is commonly used for the diagnosis of heart-related ailments, such as:

• Arrhythmias (irregular heart rhythms)
• Coronary artery disease
• Cardiac arrests
• Heart failure

Explanation

The largest cell in the human body is the female ovum.

The egg cell can be up to 100 micrometers (0.1 millimeters) in diameter, making it visible to the naked eye.

The smallest cell in the human body is the male gametes, that is, sperm

Explanation

The human cell contains 46 chromosomes.

These are organized into 23 pairs, where each parent contributes one chromosome to each pair, resulting in a total of 46 chromosomes in most human cells.

This number includes 22 pairs of autosomes and 1 pair of sex chromosomes, determining an individual's sex (XX for females and XY for males).
