Circulatory System Flashcards
What is the role of the circulatory system?
Transport of materials and protection against disease
What does the circulatory system transport?
Blood cells carrying oxygen Digested food products Carbon dioxide Hormones Urea
What are the four chambers of the heart in order of blood circulation?
Right Atrium
Right Ventricle
Left Atrium
Left Ventricle
What does the structure of the heart relate to?
Pumping action and sequence of blood flow in a double circulatory system
Identify the 4 blood vessels associated with the heart and the types of blood they carry.
Vena Cava-Deoxygenated
Pulmonary Artery-Deoxygenated
Pulmonary Vein-Oxygenated
Aorta-Oxygenated
Describe Arteries
Carry oxygenated blood normally
High pressure
Carries blood away from heart
Describe veins
Carry deoxygenated blood normally
Valves to prevent backflow
Carries blood back from heart
Describe capillaries
Allow the exchange of material with tissues through permeable walls
What artery carries what type of blood to the brain?
Carotid Artery
Oxygenated
What artery carries what type of blood to the liver?
Hepatic artery
Oxygenated
What artery carries what type of blood to the kidney?
Renal artery
Oxygenated
What artery carries what type of blood to the lungs from the heart?
Pulmonary artery
Deoxygenated
What vein carries what type of blood away from the brain to the heart?
Jugular vein
Deoxygenated
What vein carries what type of blood from the small intestine to the liver?
Hepatic portal vein
Deoxygenated
What vein carries what type of blood from the liver to the heart?
Hepatic vein
Deoxygenated
What artery carries what type of blood from the heart to the lungs?
Pulmonary Artery
Deoxygenated
What vein carries what type of blood from the lungs to the heart?
Pulmonary vein
Oxygenated
What artery carries what type of blood from the heart to the rest of the body?
Aorta
Oxygenated
What type of vein carries what type of blood from the body to the heart?
Vena Cava
Deoxygenated
What does a blockage of the coronary vessels cause?
A heart attack as blood is being slowed down or stopped from getting to the heart, causing heart cells to die.
What does a blockage in the blood vessels to the Brain cause?
Leads to a stroke causing brain cell death and reduced brain function
What do blockages in general lead to in blood vessels?
Less oxygen and glucose reaching cells and therefore less respiration, resulting in death of cells
