Study Notes
The Circulatory System
- Oxygenated blood is pumped from the heart to cells via arteries
- The aorta is the main artery transporting blood away from the heart
- The aorta branches into smaller arteries (like liver artery, intestinal artery, renal artery)
- Deoxygenated blood travels from cells to the heart through veins
- Superior and inferior vena cava are the primary veins returning blood to the heart
- These veins collect blood from smaller veins (like liver vein, renal vein)
- Pulmonary and systemic circulation combine to form a complete cycle
- The heart's cells need oxygen and nutrients and need waste removal
Coronary Circulation
- Heart muscle (cardiac muscle) needs oxygen and nutrients, and must remove waste
- Cardiac tissues have their own blood supply - called the coronary circulation
- A small part of oxygenated blood from the aorta flows to coronary arteries
- Blood in coronary veins is deoxygenated and returns to the pulmonary artery
Types of Muscle Tissue
- Voluntary (skeletal) muscle: strong, tires quickly
- Involuntary (smooth) muscle: weaker, does not tire quickly
- Cardiac muscle: combines characteristics of both voluntary and involuntary muscles
