About This Presentation

Description : Check out this medical PowerPoint presentation titled "Cardiovascular System Alterations".

This medical PowerPoint presentation talks about Cardiovascular System Alterations.

The cardiovascular system is responsible for circulating blood throughout the body, providing oxygen and nutrients to tissues and organs, and removing waste products. Alterations in the cardiovascular system can have a significant impact on overall health and can lead to a variety of diseases and conditions.

The presentation talks about some common cardiovascular system alterations like Hypertension, Coronary artery disease, Heart failure, Arrhythmias, Atherosclerosis, Valve disorders, and Peripheral artery disease.
