Study Notes
Circulatory System
Overview
- The circulatory system, also known as the cardiovascular system, is responsible for transporting oxygen and nutrients to cells and removing waste products.
- It consists of the heart, blood vessels, and blood.
Heart
- The heart is a muscular organ that pumps blood throughout the body.
- It is divided into four chambers: left and right atria, and left and right ventricles.
- The heart beats around 100,000 times per day, pumping approximately 2,000 gallons of blood.
Blood Vessels
- There are three types of blood vessels:
- Arteries: carry oxygenated blood away from the heart to the rest of the body.
- Veins: carry deoxygenated blood back to the heart.
- Capillaries: allow for the exchange of oxygen and nutrients with cells.
Blood
- Blood is a liquid tissue that consists of:
- Plasma: a liquid portion that carries proteins, nutrients, and waste products.
- Red Blood Cells (RBCs): carry oxygen from the lungs to the body's tissues.
- White Blood Cells (WBCs): part of the immune system, helping to fight infections.
- Platelets: involved in blood clotting.
Blood Circulation
- The circulatory process involves:
- Pulmonary circulation: oxygen-depleted blood from the body returns to the heart, then to the lungs to pick up oxygen.
- Systemic circulation: oxygen-rich blood from the lungs returns to the heart, then is pumped to the rest of the body.
Functions
- The circulatory system performs several critical functions:
- Oxygenation: delivers oxygen to cells and tissues.
- Nutrient delivery: transports nutrients from the digestive system to cells.
- Waste removal: removes waste products from cells and tissues.
- Regulation of body temperature: helps to maintain a stable body temperature.
- Maintenance of pH balance: helps to regulate the body's acid-base balance.
