Anatomy of a Human Heart

The cardiovascular system is a closed system if the heart and blood vessels. The heart pumps blood through a closed system of blood vessels. Blood vessels allow blood to circulate to all parts of the body. The vital importance of the heart is obvious. If one assumes an average rate of contraction of 75 contractions per minute, a human heart would contract approximately , times in one day, more than 39 million times in one year, and nearly 3 billion times during a year lifespan. Each of the major pumping chambers of the heart ejects approximately 70 mL blood per contraction in a resting adult.

Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart : involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another. The heart functions as a pump and acts as a double pump in the cardiovascular system to provide a continuous circulation of blood throughout the body. This circulation includes the systemic circulation and the pulmonary circulation. Both circuits transport blood but they can also be seen in terms of the gases they carry. The pulmonary circulation collects oxygen from the lungs and delivers carbon dioxide for exhalation.

Anatomy of a Human Heart

The human heart is a finely-tuned instrument that serves the whole body. It is a muscular organ around the size of a closed fist, and it sits in the chest, slightly to the left of center. This delivers oxygen- and nutrient-rich blood to tissues and organs and carries away waste. The heart sends deoxygenated blood to the lungs, where the blood loads up with oxygen and unloads carbon dioxide, a waste product of metabolism. Together, the heart, blood, and blood vessels — arteries, capillaries, and veins — make up the circulatory system.

Your heart does a lot of work to keep the body going. Each day, the average human heart beats about , times, pumping 2, gallons of blood through the body. In fact, the heart does more physical work than any other muscle over a lifetime.

Затем наступила тишина. Мгновение спустя, словно в дешевом фильме ужасов, свет в ванной начал медленно гаснуть. Затем ярко вспыхнул и выключился. Сьюзан Флетчер оказалась в полной темноте.
