Welcome to the collection of images dedicated to one of the most important organs in the human body — the heart. This vital muscular organ plays a key role in maintaining the health and function of the body. The heart is the center of circulation, pumping blood and ensuring the delivery of oxygen and nutrients to all cells.

Physical Characteristics

The heart typically has a cone shape and consists of four chambers: two atria and two ventricles, surrounded by a protective covering — the pericardium. It weighs on average about 300 grams and is located in the thoracic cavity between the lungs, slightly shifted to the left. The walls of the heart are made of muscular tissue called myocardium, allowing it to contract efficiently.

Surroundings of the Heart

The heart is located in the mediastinum and is protected by the ribs, providing safety for this vital organ. Around it, the circulatory system forms a closed loop, where arteries and veins function as highways, ensuring constant blood flow.

Functions and Features

The main function of the heart is to create the pressure necessary to move blood throughout the body. It initiates the circulation cycle in four stages: filling, contraction, blood ejection, and relaxation. This is a complex and coordinated process that requires the precise operation of all parts of the heart.

Seasonal Variations

Like many organs, the heart also depends on external factors such as physical activity, climatic conditions, and overall health status. For example, in cold months, the heart's workload may increase due to the need to maintain body temperature, which affects its function.

Environmental Elements

Caring for heart health leads to an improved quality of life and an increased duration of active existence. Healthy habits, such as a balanced diet and regular physical exercise, are important for its functioning. Heart care becomes an integral part of overall well-being, making it a central element in our pursuit of a healthy life.
