Oct 31, 2024 · The heart cavity is divided down the middle into a right and a left heart, which in turn are subdivided into two chambers. The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle. The two atria act as receiving chambers for blood entering the heart; the more muscular ventricles pump the blood out of the ...

The heart is one of the most important organs in the human body. It is a powerful fist-sized muscle that pumps blood around the body through a network of blood vessels – together, the heart and blood vessels make up the body’s cardiovascular system. Our hearts beat on average 72 times every minute – over 100,000 times per day.
The heart is a muscular organ found in most animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

Your heart pumps blood through three types of blood vessels: Arteries carry oxygen-rich blood from your heart to your body’s tissues. The exception is your pulmonary arteries, which go to your lungs. Veins carry oxygen-poor blood back to your heart. Capillaries are small blood vessels where your body exchanges oxygen-rich and oxygen-poor blood.
