What is the blood circulation system?
The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart. The system of blood vessels resembles a tree: The “trunk” – the main artery (aorta) – branches into large arteries, which lead to smaller and smaller vessels. The smallest arteries end in a network of tiny vessels known as the capillary network.
Where does pulmonary circulation begin?
This is where pulmonary circulation begins: The right ventricle pumps low-oxygen blood into the pulmonary artery, which branches off into smaller and smaller arteries and capillaries. The capillaries form a fine network around the pulmonary vesicles (grape-like air sacs at the end of the airways).
How many blood circulatory systems are there in the human body?
There isn't only one blood circulatory system in the human body, but two, which are connected: The systemic circulation provides organs, tissues and cells with blood so that they get oxygen and other vital substances.

Which part of the body pumps oxygen-rich blood into the main artery?
In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta). The blood travels from the main artery to larger and smaller arteries and into the capillary network. There the blood drops off oxygen, nutrients and other important substances and picks up carbon dioxide and waste products.
How does the circulatory system help you?
Your circulatory system plays a critical role in keeping you alive. Blood vessels carry blood to the lungs for oxygen. Then your heart pumps oxygen-rich blood through arteries to the rest of the body. Your veins help your body get rid of waste products. Conditions like high blood pressure, high cholesterol and atherosclerosis can affect the health of your circulatory system. If you have one of these conditions, talk to your healthcare provider about steps you can take to protect your cardiovascular health.
What is the system of blood vessels called?
Your heart pumps blood to the body through a network of arteries and veins (blood vessels). Your circulatory system can also be defined as your cardiovascular system. Cardio means heart, and vascular refers to blood vessels.
Which system pumps blood to the lungs?
The circulatory system ( cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.

What is the blood circulation system?
This system is tasked with providing oxygen and nutrients to every cell in an organism’s body.
What is the process of releasing carbon dioxide into the air?
In the lungs, the capillaries form a minuscule network around the air-sacs called pulmonary vesicles . At this point, carbon dioxide is released from the bloodstream and into the air in the pulmonary vesicles. The carbon dioxide leaves our body when we exhale. As we inhale, fresh oxygen enters the bloodstream through the alveoli and the blood becomes oxygen-rich. The oxygen-rich blood then travels from the lungs through the pulmonary veins and into the left ventricle. The subsequent heartbeat results in a new systemic circulation cycle.
What type of circulation is where oxygen enters the bloodstream?
Pulmonary circulation is the type of circulation where fresh oxygen enters the bloodstream, and simultaneously, carbon dioxide is also removed from the bloodstream. Read More: Double Circulation – Blood Circulation in Humans.

How does blood flow through your lungs?
Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale. Once the blood is purified and oxygenated, it travels back to the left atrium through the pulmonary veins.
How does blood flow through the right ventricle?
Blood flows from your right atrium into your right ventricle through the open tricuspid valve. When the ventricles are full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze).
