What are the parts of the circulatory system and their functions?
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.
What are the 3 basic 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 are the 5 functions of the heart?
The four main functions of the heart are:
- Pumping oxygenated blood to the other body parts.
- Pumping hormones and other vital substances to different parts of the body.
- Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation.
- Maintaining blood pressure.
What is the main function of heart?
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 four basic components of any circulatory system?
The circulatory system consists of four major components: The Heart: About the size of two adult hands held together, the heart rests near the center of the chest. Arteries: Arteries carry oxygen-rich blood away from the heart and where it needs to go. Veins: Veins carry deoxygenated blood to the lungs where they receive oxygen.
How does the circulatory perform its main function?
The circulatory system works thanks to constant pressure from the heart and valves throughout the body. This pressure ensures that veins carry blood to the heart and arteries transport it away from the heart. (Hint: to remember which one does which, remember that that “artery” and “away” both begin with the letter A.)
What does the human circulatory system exactly do?
