The general function of the cardiovascular system is to transport blood throughout the body to allow the exchange of substances (e.g., respiratory gases, nutrients, and waste products) between the blood of capillaries and the body’s cells.
What are the 3 main functions of the cardiovascular system quizlet?
Its functions include: 1) carries food and oxygen to the different cells of the body ; 2) carries body wastes away; 3) protects the body from diseases; and 4) serves as the body’s defense system.
What are the 3 main function of the cardiovascular system?
- transport of oxygen, carbon dioxide and nutrients.
- clotting of open wounds.
- regulation of body temperature.
What is the cardiovascular system and what are its functions?
The cardiovascular system is the transport system of the body, responsible for circulating oxygen and transporting nutrients throughout the body . In addition to providing oxygen and nutrients, blood also helps cleanse the body by collecting waste products like carbon dioxide.
What are the main functions of the cardiovascular system?
- Circulates OXYGEN and removes Carbon Dioxide.
- Provides cells with NUTRIENTS.
- Removes the waste products of metabolism to the excretory organs for disposal.
- Protects the body against disease and infection.
- Clotting stops bleeding after injury.
What are the four components of the cardiovascular system?
The main components of the cardiovascular system are the heart, blood vessels, and blood . Each of these components is shown in Figure 17.2.
What three main parts make up the circulatory cardiovascular system?
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic) . The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
Which describes the role of the heart in the cardiovascular system?
It’s the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.
What are the signs and symptoms of common cardiovascular system disorders?
- Chest tightness or pressure.
- Difficulty catching your breath.
- Dizziness or fainting.
- Fatigue.
- Fluid build up.
- Heart palpitations (heart pounding or racing).
- Pain or numbness in your legs or arms.
- Abdominal pain, nausea, vomiting.
What is the pathway of blood through the heart quizlet?
Oxygen-poor blood enters heart thru the Inferior Vena Cava or the Superior Vena Cava . It enters the right atrium and flows through the Tricuspid Valve into the right ventricle. The left ventricle pumps the blood through the aortic (semilunar) valve to the Aorta, where the oxygen-rich blood returns to the body.
What is the most important part of the cardiovascular system?
The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. It usually beats from 60 to 100 times per minute, but can go much faster when necessary.
What is cardiovascular system simple definition?
Human cardiovascular system, organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes. It is a closed tubular system in which the blood is propelled by a muscular heart.
What are the 5 main parts of the cardiovascular system?
The cardiovascular system, also known as the circulatory system, includes the heart, arteries, veins, capillaries and blood . The heart functions as the pump that moves blood through the body.
What are the two components of the cardiovascular system?
The essential components of the human cardiovascular system are the heart, blood and blood vessels . It includes the pulmonary circulation, a “loop” through the lungs where blood is oxygenated; and the systemic circulation, a “loop” through the rest of the body to provide oxygenated blood.
What is the components of cardiovascular system?
The cardiovascular system is sometimes called the blood-vascular, or simply the circulatory, system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries .
What is the difference between cardiovascular system and circulatory system?
From the hard-working heart, to our thickest arteries, to capillaries so thin that they can only be seen through a microscope, the cardiovascular system is our body’s lifeline. The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries.
