Study Notes
Arterial Structure and Function
- Smooth muscle cells are arranged circularly around arteries, allowing for diameter regulation.
- This regulation of diameter controls blood flow throughout the circulatory system.
- Thick smooth muscle layers enable arteries to constrict or dilate as needed.
Vein Structure and Function
- Veins possess a unique structure that facilitates material exchange between blood and surrounding tissues.
- This exchange supports key functions, including nutrient absorption and filtration.
Types of Capillaries
- Continuous capillaries are the most prevalent type found in the body, playing a crucial role in circulation.
Composition of Blood
- Blood consists of several components:
- Red blood cells (erythrocytes) transport oxygen.
- White blood cells (leukocytes) are essential for immune response.
- Platelets (thrombocytes) are involved in clotting.
- Plasma serves as the fluid medium, containing nutrients, hormones, and waste products.
