Human Body Flashcards
Plasma
Liquid part of the blood,mostly made of water.Transports blood cells ,glucose and water etc.
Haemoglobin
Red pigment that contains iron.Located in red blood cells,carries oxygen.
Aorta
Oxygenated blood leaves the heart to go to the rest of the body.
Venae cavae
Deoxygenated blood enters the right atrium of the heart through the venae cavae
Septum
The heart is a double pump, separated into a left and right side by the septum.
Atria
The upper chambers of the heart,where blood first enters the heart.
Ventricles
The lower chambers of the heart where blood goes when it leaves the atria
Pulmonary artery
Brings deoxygenated blood from the body to the heart.
Valves
Gateways that open and close to let blood flow through the heart,and stop backflow in the veins
Pulse
A wave of vibrations that passes through an artery in response to blood being forced out of the left ventricle.
Oxygenated blood
Blood rich in oxygen that comes from the lungs.
Deoxygenated blood
Blood that comes from other parts of the body that has less oxygen,and more carbon dioxide.It must go to the lungs to get more oxygen.
Healthy heart
A balanced diet, exercise and rest are very important for a healthy heart.
Pulse investigation
Plan,Design,carry out and write up an investigation to examine the effect of exercise on pulse rate.You May use the timer on your iPad as a stopwatch.Consider how you will
measure the pulse.Do you need a control?How will you ensure accuracy?
How long does it take for the pulse to go back to normal resting rate?what does this show?
