Study Notes
Cardiovascular System
- Refers to the system that facilitates the circulation of blood and lymph throughout the body, crucial for transporting nutrients, gases, hormones, and wastes.
Circulatory System of Vertebrates
- Comprises the heart, blood vessels (arteries, veins, and capillaries), and blood, functioning to circulate blood and maintain homeostasis.
Divisions of the Circulatory System
- Consists of two main divisions:
- Pulmonary Circulation: Transports deoxygenated blood from the heart to the lungs for oxygenation and back to the heart.
- Systemic Circulation: Carries oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart.
Composition of Blood in Vertebrates
- Blood is composed of:
- Red Blood Cells (Erythrocytes): Carry oxygen via hemoglobin.
- White Blood Cells (Leukocytes): Play a key role in immune responses.
- Platelets (Thrombocytes): Assist in clotting and wound healing.
- Plasma: Liquid portion containing water, electrolytes, nutrients, hormones, and waste products.
Circulatory System in Invertebrates (e.g., Arthropods)
- Characterized by an open circulatory system, where blood (hemolymph) is not confined to blood vessels and is directly in contact with organs, allowing for nutrient and gas exchange.
