Human Circulatory System
The circulatory system is a network of organs and tissues that circulates blood throughout the body. It includes the heart, blood vessels, and blood. The heart is a muscular organ that pumps blood through the blood vessels. The blood vessels carry blood to and from the tissues and organs of the body. The blood contains oxygen and nutrients that are necessary for the tissues to function.
Circulatory System Meaning
The circulatory system is a network of organs and vessels that circulates blood throughout the body. The heart is the central organ of the circulatory system and pumps blood through the arteries and veins. The blood carries oxygen and nutrients to the tissues and removes waste products.
Components of Circulatory System
The circulatory system is a network of organs and vessels that circulates blood throughout the body. The heart is the central organ of the circulatory system, and it pumps blood through the arteries and veins. The arteries carry blood away from the heart, and the veins carry blood back to the heart. The blood contains oxygen and nutrients that are essential for the body’s health.
Heart rate
The heart rate is the number of times the heart beats in one minute. It is controlled by the autonomic nervous system, which is responsible for most of the body’s automatic functions. The autonomic nervous system is divided into the sympathetic and the parasympathetic systems. The sympathetic system speeds up the heart rate, while the parasympathetic system slows it down.
Lungs
The lungs are a pair of organs in the chest that help you breathe. They take in oxygen from the air and put it into your bloodstream. They also take carbon dioxide from the bloodstream and put it into the air.
Systemic Circulation
Systemic circulation refers to the flow of blood throughout the body. The heart is responsible for pumping blood through a series of vessels called the systemic circulation. These vessels carry blood to all parts of the body, including the lungs, where the blood picks up oxygen. The blood then returns to the heart and is pumped back out to the rest of the body.
The Systemic Circulation
The systemic circulation is the portion of the cardiovascular system that carries blood from the heart to the rest of the body. The systemic circulation begins when deoxygenated blood leaves the left ventricle of the heart and enters the aorta. The aorta is a large blood vessel that carries the blood to all of the organs in the body. The blood passes through the organs and is eventually returned to the heart via the veins.
The Pulmonary Circulation
The pulmonary circulation is the portion of the cardiovascular system that carries oxygenated blood from the lungs to the rest of the body. The pulmonary circulation consists of the pulmonary arteries, which carry oxygenated blood from the lungs to the heart, and the pulmonary veins, which carry deoxygenated blood from the heart to the lungs.
