What is the system of blood vessels?

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.

What is the process of oxygen entering the blood?

The pulmonary circulation is where the fresh oxygen we breathe in enters the blood. At the same time, carbon dioxide is released from the blood. Blood circulation starts when the heart relaxes between two heartbeats: The blood flows from both atria (the upper two chambers of the heart) into the ventricles (the lower two chambers), which then expand.

What is the circulatory system?

The Human Circulatory system is an organ system that contains the heart and the blood vessels and moves blood throughout the body in a closed network of blood capillaries. Humans have a closed circulatory system. The human circulatory system functions to transport blood and oxygen from the lungs to the various tissues ...

What are the two main types of circulatory systems?

The two systems are the open circulatory system and the closed circulatory system.

Which organ system is responsible for the transport of oxygen, carbon dioxide, amino acids, electrolytes, and other molecules

The organ system responsible for the circulation of nutrients and transport of oxygen, carbon dioxide, amino acids, electrolytes, hormones, or other molecules and nutrients throughout the body is called the circulatory system .

How many chambers does the circulatory system have?

The human circulatory system functions to transport blood and oxygen from the lungs to the various tissues of the body. The human heart consists of four chambers – two ventricles and two auricles.

What is the function of the lymphatic system?

The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body. The lymphatic system comprises lymph, lymphatic capillaries, ...

What is the portal system?

A portal system is a network of blood capillaries that connect two organs or tissues, e.g., the hepatic portal system connects the small intestines to the liver via the hepatic portal vein.

How does the circulatory system help the body?

The circulatory system helps in transporting oxygen throughout the body. It circulates oxygen and removes carbon dioxide from the body. It transports blood , nutrients, hormones, etc., throughout the body. It helps in the removal of the waste products of metabolism to the excretory organs for disposal.

What is the circulatory system?

Your circulatory system, also known as your cardiovascular system, is made up of your heart and blood vessels. It works to transport oxygen and other nutrients to all the organs and tissues in your body. It also works to remove carbon dioxide and other waste products. Having a healthy circulatory system is vital to your health and well-being.

Which blood vessels carry oxygenated blood away from the heart?

Arteries. These thick-walled blood vessels carry oxygenated blood away from your heart. Veins. These blood vessels carry deoxygenated blood back toward your heart. Capillaries. These tiny blood vessels facilitate the exchange of oxygen, nutrients, and waste between your circulatory system and your organs and tissues.

What is the function of capillaries?

Its function is to distribute blood and other nutrients to all your body’s organs and tissues. The small blood vessels called capillaries facilitate the exchange of oxygen and nutrients between your blood and the cells in your body. Carbon dioxide and other waste products, which are expelled from your body, are also exchanged via your capillaries.

Where does oxygenated blood go?

In the lungs, the blood gets rid of carbon dioxide and picks up fresh oxygen. Newly oxygenated blood returns to the other side of the heart (the left side), where it’s then pumped into the arteries.

What is it called when you don't get enough oxygen?

Because of this, organs and tissues may not get enough oxygen. When atherosclerosis affects the arteries of your heart, it’s called coronary artery disease. Other arteries in your body can also be affected as well. This is called peripheral artery disease, which affects how well blood can flow to your legs, feet, arms, and hands.

What is it called when your legs are blocked?

This is called peripheral artery disease, which affects how well blood can flow to your legs, feet, arms, and hands. In some cases, an artery may become completely blocked by plaque or a blood clot. When this happens, a heart attack or stroke can occur.

What does high blood pressure do to your body?

High blood pressure can eventually damage your heart and blood vessels, as well as other organs like your brain, kidneys, and eyes.
