Circulatory System
Flashcards do conjunto (20)
- 1Tell me about Single Circulatory Systems...Low pressure, flows around the body in a single circuit, the heart has two chambers, deoxygenated blood is pumped to the gills, then oxygenated blood is pumped to the body. e.g. fish
- 2Tell me about Double Circulatory Systems...Heart has four chambers e.g. humans
- 3What does the CORONARY ARTERY do?It supplies the heart itself with glucose and oxygen.
- 4What does the PULMONARY VEIN do?It carries oxygenated blood from the lungs to the heart.
- 5What does the AORTA do?It carries oxygenated blood from the heart to the rest of the body.
- 6What does the VENA CAVA do?It carries deoxygenated blood from the parts of the body back to the heart.
- 7What does the PULMONARY ARTERY do?It carries deoxygenated blood from the heart to the lungs.
- 8This needs a constant supply of glucose and oxygen to release energy through respiration.THE HEART
- 9Carry blood under high pressure away from the heart.ARTERIES
- 10Have valves to prevent backflow.VEINS
- 11The heart pumps blood around the body through...BLOOD VESSELS
- 12Name 3 places that you can take your pulseneck, wrist, ear or temple
- 13A measure of the heart beat (muscle contraction) to put the blood under pressure...A PULSE
- 14The heart beat is controlled by groups of cells called...THE PACEMAKER
- 15What does a pacemaker do?Produces small electrical impulses, which spread across the heart muscle, stimulating it to contract.
- 16What is the SINOATRIAL NODE (SAN)?It provides impulses that spread across the atria to make them contract.
- 17What is the ATRIOVENTRICULAR NODE (AVN)?It relays impulses that spread over the ventricles to make them contract.
- 18What is the name of a hormone that can alter the heart rate?ADRENALINE
- 19What is the test called where you can monitor the electrical impulses from the heart?ELECTROCARDIOGRAM (ECG)
- 20What is the test called that uses ultrasound to produce an image of the beating heart?ECHOCARDIOGRAM
