What is the cardiovascular system Pe?
Structure of the cardiovascular system It carries oxygenated blood away from the left ventricle to the body. The vena cava is the largest vein in the body. It carries deoxygenated blood from the body back to the heart.
What are the 4 types of cardiovascular system?
Four of the main types are described below.
- Coronary heart disease. Coronary heart disease occurs when the flow of oxygen-rich blood to the heart muscle is blocked or reduced.
- Strokes and TIAs.
- Peripheral arterial disease.
- Aortic disease.
What is the cardiovascular system GCSE?
The heart works as a double circulatory system. This means two pumps that work at the same time to pump blood in two different directions. The right-hand side of the heart collects deoxygenated blood from the body and pumps it to the lungs (to collect more oxygen). This is called pulmonary circulation.
What is BP GCSE PE?
What is blood pressure? Blood pressure (BP) is defined as the force exerted by the blood against the vessel wall. It is highest in arteries as these are the first blood vessels it flows into from the heart and gradually decreases as it passes through arterioles, capillaries, venules and finally, veins.
What are the 3 major components of the cardiovascular system?
While there are numerous mechanisms and processes that help regulate and promote the circulation of blood, there are three main parts of the cardiovascular system.
- Blood.
- Blood Vessels.
- Heart.
What are 3 main functions of the circulatory system?
The cardiovascular system has three main functions:
- transport of oxygen, carbon dioxide and nutrients.
- clotting of open wounds.
- regulation of body temperature.
What is a Class 3 or Class 4 cardiac condition?
Class I and II are typically categorized as mild heart failure, while class III and IV are considered more severe or advanced heart failure. A person can move back and forth between these classes based on their symptoms.
What are the 3 main functions of the cardiovascular system?
What is the main structure of the cardiovascular system?
The cardiovascular system consists of the heart, blood vessels, and blood. Its primary function is to transport nutrients and oxygen-rich blood to all parts of the body and to carry deoxygenated blood back to the lungs.
How does the cardiovascular system work?
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.
