Heart: The heart is a muscular organ that pumps blood throughout the body. It consists of four chambers - the left and right atria, and the left and right ventricles.
Consider real-life examples and case studies to relate the concepts to practical situations
Summary
The cardiovascular system is a complex network responsible for the circulation of blood and the transport of essential substances throughout the body. Understanding its structure, functions, and related diseases is crucial for gaining a comprehensive knowledge of human anatomy and physiology.
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
