The human body comprises several critical physiological systems, including:
- Cardiovascular System: Responsible for pumping and distributing blood throughout the body. - Respiratory System: Facilitates the exchange of oxygen and carbon dioxide. - Nervous System: Controls and coordinates body activities through nerve signals. - Endocrine System: Regulates bodily functions through hormones. - Renal System: Maintains fluid and electrolyte balance and removes waste products.
