OverviewWhat is the circulatory system?Your heart and blood vessels make up the circulatory system. The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body. Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it. Show
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. The circulatory system provides blood to all the body's tissues so they can function. FunctionWhat does the circulatory system do?The circulatory system’s function is to move blood throughout the body. This blood circulation keeps organs, muscles and tissues healthy and working to keep you alive. The circulatory system also helps your body get rid of waste products. This waste includes:
How does the circulatory system work?Your circulatory system functions with the help of blood vessels that include arteries, veins and capillaries. These blood vessels work with your heart and lungs to continuously circulate blood through your body. Here’s how:
AnatomyWhat are the circulatory system parts?The parts of your circulatory system are your:
What are the circulatory system circuits?Your circulatory system has three circuits. Blood circulates through your heart and through these circuits in a continuous pattern:
What are the types of blood vessels?There are three main types of blood vessels:
What are the circulatory system organs?Your heart is the only circulatory system organ. Blood goes from the heart to the lungs to get oxygen. The lungs are part of the respiratory system. Your heart then pumps oxygenated blood through arteries to the rest of the body. Conditions and DisordersWhat conditions affect the circulatory system?Many conditions can affect the health of your circulatory system, including:
CareHow can I prevent circulatory system problems?These steps can protect the health of your circulatory system:
Frequently Asked QuestionsHow big is the circulatory system?Your body has more than 60,000 miles of blood vessels that circulate about 1.5 gallons of blood every day. What is red blood and blue blood?All blood is red. Hemoglobin, an iron-rich protein in red blood cells, mixes with oxygen to give blood its red color. Blood that’s rich in oxygen is known as red blood. Your veins carry oxygen-poor blood. This is sometimes called blue blood because your veins can look blue underneath the skin. The blood is actually red, but the low oxygen levels give veins a bluish hue. Do arteries always carry oxygenated blood?For the most part, yes. The exceptions are pulmonary arteries and veins. Pulmonary arteries carry deoxygenated blood to the lungs. Pulmonary veins return the oxygenated blood to the heart. A note from Cleveland Clinic 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. Which of the following refers to the ability of the heart cardio and circulatory system?Cardiovascular endurance is the ability of the heart, lungs, and circulatory system to supply oxygen and nutrients to working muscles efficiently.
Which of the following is the ability of the heart to supply oxygen to the muscles *?Option (B) Cardiovascular Endurance is the ability of the heart, lungs, blood vessels, and blood to work efficiently and to supply the body with oxygen. Explanation: Cardiovascular endurance is the capability of our body to carry out high-intensity exercises for a period of time without being exhausted.
Is the ability of the circulatory system to supply oxygen?Cardiorespiratory fitness is defined as a component of physiologic fitness that relates to the ability of the circulatory and respiratory systems to supply oxygen during sustained physical activity.
What is the ability of cardiovascular system of the body to supply energy?It is is Cardiorespiratory endurance.
It is the ability of the heart, lungs, and circulatory system to supply oxygen/Energy and nutrients to working muscles efficiently and smoothly.
