The area of biology known as physiology is concerned with the study of how living things work and how they are made. A branch of physiology called cardiac physiology is dedicated to the study of the heart and its operations.
The area of biology known as “physiology” focuses on understanding how living things work and go about performing various body functions. It aims to comprehend the mechanisms and procedures that take place inside the body to preserve life and enable it to adjust to various environmental circumstances. The study of many different activities, including those relating to organs, tissues, cells, and even molecular processes, falls under the umbrella of physiology.
The study of the heart and how it functions within the circulatory system is the focus of the subject of physiology known as cardiac physiology. It dives into the complex mechanisms of the heart, such as how it beats to pump blood throughout the body, how it controls its own rhythm, and how it collaborates with the circulatory system to supply oxygen and nutrients to different tissues and organs. Cardiac physiology also investigates the mechanical and electrical components of the heart’s activity, as well as the conditions and drugs that may impair it. For the proper diagnosis and management of heart-related illnesses as well as the preservation of general cardiovascular health, comprehension of cardiac physiology is crucial.

Numerous physiological conditions exist, each with a unique set of therapeutic options, such as diabetes, hypertension, and cardiovascular disease.
Q3: How does physiology change with age?
Age-related physiological changes include decreasing bone density, decreased muscle mass, and a deterioration in organ performance.
Q4: What exactly is a cardiac cycle?
The series of actions that take place throughout a full heartbeat, such as atrial and ventricular contraction and relaxation, is known as the cardiac cycle.
Q5: What is an electrocardiogram, or ECG?
An ECG is a test that documents the heart’s electrical activity throughout time. It is frequently used to identify and keep track of different heart problems.
Q6: What exactly is the heart's conduction system?
The network of specialized cells known as the cardiac conduction system ensures that the heart beats in a coordinated and regular pattern by carrying electrical messages there.
Q7: How are the cardiovascular system and other bodily systems related?
To control blood pressure, heart rate, and other crucial processes, the cardiovascular system collaborates closely with the respiratory, neurological, and endocrine systems.
