Q

Circulatory System

A

Q

Arteries

A

hollow tubes (vessels) with thick walls carrying blood pumped from the heart to other body parts. There is the pulmonary artery which directs deoxygenated blood to the lungs and the Aorta which directs oxygenated blood to organs/around the body.

Q

Oxygen

A

a gas in the air (and water) that animals need to breathe in; made up of particles with two oxygen atoms. Plants produce oxygen as part of photosynthesis.

16
Q

Deoxygenated blood

A

describes blood from which some oxygen has been removed

17
Q

Vena Cava

A

large vein leading into the top right chamber of the heart

18
Q

Left Atrium

A

upper left section of the heart where oxygenated blood from the lungs enters the heart

19
Q

Right Atrium

A

upper right section of the heart where deoxygenated blood from the body enters

20
Q

Left Ventricle

A

lower left section of the heart, which pumps oxygenated blood to all parts of the body

21
Q

Right Ventricle

A

lower right section of the heart, which pumps deoxygenated blood to the lungs

22
Q

Valves

A

flap-like folds in the lining of a blood vessel or other hollow organ that allow a liquid, such as blood, to flow in one direction only. There is the Tricuspid valve inbetween the right Atrium and right Ventricle, and the Bicuspid (mitral) valve inbetween the left Atrium and left ventricle. With the pulmonary artery is the pulmonary valve. With the Aorta is the Aortic valve.

23
Q

‘Lub Dub’

A

the sound made by the heart valves as they close

24
Q

Blood Pressure

A

measures how strongly the blood is pumped through the body’s main arteries

25
Q

Systolic Pressure

A

the higher blood pressure reading during contraction of the heart muscles

26
Q

Diastolic Pressure

A

the lower blood pressure reading during relaxation of the heart muscles

27
Q

Heartbeat

A

contraction of the heart muscle occurring about 60–100 times per minute

28
Q

Pulse

A

alternating contraction and expansion of arteries due to the pumping of blood by the heart

29
Q

Pacemaker

A

electronic device inserted in the chest to keep the heart beating regularly at the correct rate. It works by stimulating the heart with tiny electrical impulses.

30
Q

Cardiac Muscle

A

special kind of muscle in the heart that never tires. It is involved in pumping blood through the heart.

31
Q

Pulmonary artery

A

the vessel through which deoxygenated blood, carrying wastes from respiration, travels from the heart to the lungs

32
Q

Pulmonary vein

A

the vessel through which oxygenated blood travels from your lungs to the heart

33
Q

Aorta

A

a large artery through which oxygenated blood is pumped at high pressure from the left ventricle of the heart to the body

34
Q

Arterioles

A

vessels that transport oxygenated blood from the arteries to the capillaries

35
Q

Venules

A

Small veins
