Chapter 3 - The Cardiorespiratory System Flashcards
The superior chamber of the heart that receives blood from the veins and forces it into the ventricles.
Atrium
The inferior chamber of the heart that receives blood from its corresponding atrium and, in turn, forces blood into the arteries.
Ventricles
Gathers deoxygenated blood returnin to the heart from the entire body
Right atrium
Gathers oxygenated blood coming to the heart from the lungs
Left atrium
thin wall and pumps blood under low pressure a short distance to the lungs
Right Ventricle
Thicker walled and pumps blood under high pressure as it pumps it out to the rest of the body.
Left Ventricle
Receives deoxygenated blood from the right atrium and then pumps it to the lungs to be saturated with incoming oxygen.
Right Ventricle
Receives the oxygenated blood from the left atriumand proceeds to pump it to the entire body.
Left Ventricle
Seperate the chambers of the heart to prevent a backflow or spillage of blood back into the chambers.
Atrioventicular, and semilunar valves.
Mechanism of the blood responsible for transporting oxygen and nutrients to tissues, waste products from tissues, homones to organs and tissues, and carries heat throughout the body
Transportation
Mechanism of blood resposible for regulating body temperature and acid balance in the body
Regulation
Mechanism of the blood responsible for protecting the body from excessive bleeding by clotting, and containing specialized immune cells to help fight disease and sickness.
Protection
Three support mechanisms of blood.
Transportation, Regulation, and Protection
The sternum, ribs, and vertebrae are all ________ within the structure of the _______ pump.
Bones, respiratory
The diaphragm, external intercostals, scalenes, sternocleidomastiod, and pectoralis minor are all muscles responsible for ____________ within the respiratory system.
