Study Notes
Cardiovascular System
Definition: The cardiovascular system, also known as the circulatory system, is a network of organs and vessels that transport blood throughout the body.
Functions:
- Transports oxygen and nutrients from the lungs and digestive system to the body's tissues
- Removes waste products, such as carbon dioxide, from the body's tissues
- Regulates body temperature
- Maintains blood pressure
- Supports cellular metabolism
Components:
- Heart: a muscular organ that pumps blood throughout the body
- Arteries: blood vessels that carry oxygenated blood away from the heart to the body's tissues
- Veins: blood vessels that carry deoxygenated blood back to the heart
- Blood: a liquid tissue that transports oxygen, nutrients, and waste products throughout the body
- Blood vessels: tubes that transport blood throughout the body, including arteries, veins, and capillaries
Blood Circulation:
- Pulmonary circulation: the circulation of blood between the heart and lungs, where oxygen is absorbed and carbon dioxide is removed
- Systemic circulation: the circulation of blood between the heart and the rest of the body, where oxygen and nutrients are delivered and waste products are removed
Cardiovascular Health:
- Risk factors: factors that increase the likelihood of developing cardiovascular disease, such as high blood pressure, high cholesterol, smoking, and physical inactivity
- Cardiovascular disease: conditions that affect the heart and blood vessels, such as heart attacks, strokes, and peripheral artery disease
- Prevention: maintaining a healthy diet, exercising regularly, and managing stress can help prevent cardiovascular disease
