Study Notes
Types of Blood Vessels
- Elastic arteries: Largest diameter blood vessels with thick walls, essential for accommodating high-pressure blood flow. Examples include the aorta and pulmonary trunk.
- Pulmonary vessels: Transport blood from the right ventricle of the heart to the lungs for oxygenation and back to the left atrium.
- Systemic vessels: Carry oxygenated blood from the left ventricle through the body and return deoxygenated blood to the right atrium.
Functions of Blood Vessels
- Carries blood: Main role in the circulatory system.
- Exchanges nutrients and waste: Facilitates the transfer of gases and other substances between blood and tissues.
- Transport of substances: Includes hormones and immune cells along with nutrients and oxygen.
- Regulates blood pressure: Contributes to maintaining homeostasis throughout the body.
- Directs blood flow: Adjusts the distribution of blood to various tissues based on their metabolic needs.
Vessel Structures
- Arteries: Thick-walled vessels that transport blood away from the heart, rich in elastic tissue to handle pressure changes.
- Muscular arteries: Medium to small-sized arteries characterized by a thick muscular layer, allowing regulation of blood flow to specific body regions.
- Capillaries: Small blood vessels where blood flows from arterioles, forming networks that enable the exchange of gases and nutrients; blood flow is tightly regulated.
