Circulatory System Overview
- The circulatory system, or cardiovascular system, facilitates the movement of blood, nutrients, gases, and waste throughout the body.
Main Components
-
Heart:
- Comprised of four chambers: right atrium, right ventricle, left atrium, left ventricle.
- Functions as a vital pump to propel blood throughout the body.
-
Blood Vessels:
- Arteries: Transport oxygen-rich blood away from the heart, except for pulmonary arteries.
- Veins: Carry deoxygenated blood back to the heart, except for pulmonary veins.
- Capillaries: Microscopic vessels essential for gas and nutrient exchange between blood and tissues.
-
Blood Composition:
- Made up of red blood cells (carry oxygen), white blood cells (immune response), platelets (clotting), and plasma (liquid component).
Types of Circulation
-
Systemic Circulation:
- Distributes oxygen-rich blood from the left side of the heart to the entire body, returning deoxygenated blood to the right side.
-
Pulmonary Circulation:
- Sends deoxygenated blood from the right side of the heart to the lungs for oxygenation and returns oxygenated blood to the left side.
Functions of the Circulatory System
- Facilitates the transport of oxygen and carbon dioxide.
- Distributes essential nutrients and hormones to different body parts.
- Aids in the removal of metabolic waste products.
- Regulates body temperature and maintains pH balance.
- Provides protection against diseases via immune cells and antibodies.
Key Processes
-
Heartbeat:
- Initiated and regulated by electrical signals that cause the heart to contract and relax rhythmically.
-
Blood Flow:
- Relies on pressure gradients; arteries typically maintain higher pressure than veins.
-
Exchange Mechanism:
- Nutrient and gas exchanges occur in capillaries primarily through diffusion.
Diseases and Disorders
- Hypertension: Characterized by persistently high blood pressure.
- Atherosclerosis: Condition where arteries become hardened and narrowed due to plaque accumulation.
- Heart Attack: Results from blockage of blood flow to heart muscle tissue.
- Stroke: Occurs when blood supply to the brain is interrupted.
Regulatory Mechanisms
- Regulated by the autonomic nervous system, which includes sympathetic (increases heart rate) and parasympathetic (decreases heart rate) responses.
- Hormonal influences such as adrenaline can elevate heart rate during stress or exercise.
Adaptations
- Regular exercise enhances the efficiency and capacity of the circulatory system.
- The heart undergoes hypertrophy, enlarging with consistent training to boost performance and endurance.
