Study Notes
Circulatory System
- The circulatory system is the body's internal transport system that links all cells within the body.
- It carries essential requirements needed by cells, such as nutrients and oxygen, and removes wastes.
How the Circulatory System Works
- The circulatory system is a double circulatory system, meaning it has two parts: the right side dealing with deoxygenated blood and the left side dealing with oxygenated blood.
- The blood is pumped first to the lungs, then returns to the heart to be pumped around the body.
- Pulmonary circulation: the flow of blood from the right ventricle through the lungs and back to the left atrium.
- Systemic circulation: the flow of blood from the left ventricle throughout the body and back to the right atrium.
Blood Vessels
- There are three types of blood vessels: arteries, veins, and capillaries.
- Arteries carry blood away from the heart, have elastic fibers allowing them to stretch under pressure, and have thick muscle fibers.
- Veins carry blood towards the heart, have valves to prevent backflow, and have thin muscle fibers and skeletal muscles surrounding them.
- Capillaries link arteries with veins, exchange materials between the blood and cells, and have walls that are only one cell thick.
Blood
- Blood is a liquid tissue that carries oxygen, nutrients, and waste products throughout the body.
- Blood consists of red blood cells, white blood cells, platelets, and plasma.
- Red blood cells contain hemoglobin, which carries oxygen to cells.
- White blood cells fight disease by producing antibodies and attacking infected cells.
- Platelets produce fibrinogen fibers to form a blood clot.
- Plasma carries cells and platelets, is 55% of blood volume, and consists of 92% water, 7% protein, and various nutrients and waste products.
Functions of Blood
- Transports oxygen and nutrients to cells
- Transports carbon dioxide and waste products away from cells
- Transports chemical messengers (hormones) to cells
- Maintains pH of body fluids
- Distributes heat and maintains body temperature
- Maintains water content and ion concentration of body fluids
- Protects against disease-causing microorganisms
