circulatory system

artery

tubes that carry oxygenated blood away from the heart, bright red blood and high pressure

vein

tube that carries deoxygenated blood and waste around the body, less pressure and blood is moving back to the heart

valves

prevent blood flowing backwards in veins

functions of blood

distribution, removal of waste, immunity, thermoregulation

red blood cells

haemoglobin

carry oxygen around the body

lack a nucleus (defying cell theory)

produced in the bone marrow

erythrocytes

white blood cells

produced in red bone marrow

protection

leukocytes

platelets

activated/inactivated

rhombocytes

clotting

superior vena cava

right pulmonary artery

right pulmonary veins

right atrium

pulmonary valve

tricuspid valve

right ventricle

inferior vena cava

aorta

left pulmonary arteries

pulmonary trunk

left pulmonary veins

left atrium

bicuspid valve

left ventricle

aortic valve

septum

descending aorta

tricuspid valve func

prevents backflow of venous blood to the RA to the RV

pulmonary valve func

prevents backflow of venous blood to the RV from the pulmonary trunk

aortic valve func

prevents backflow of oxygenated blood to the LV from the aorta

superior vena cava func

brings venous blood from the upper body to the RA

inferior vena cava func

brings venous blood from the lower body to the RA

right atrium function

first chamber to receive blood and pump it through the tricuspid valve to the RV

right ventricle func

accepts blood from the RA and delivers blood to the pulmonary trunk

pulmonary trunk func

carries venous blood from the RV to LV and right pulmonary arteries

right pulmonary artery func

carries venous blood from the pulmonary trunk to the right lung

left pulmonary artery func

carries blood to the left lung

right pulmonary veins func

carries oxygenated blood from the right lung to the LA

left pulmonary veins func

carries oxygenated blood from the left lung to the LA

left atrium func

collects oxygenated blood from the pulmonary veins and pumps it to the left ventricle via the mitral valve

left ventricle func

pumps oxygenated blood to the rest of the body through the aortic valve and aorta

aorta func

carries oxygenated blood from the LV to the body

septum func

divides the left and right part of the heart

lub sound

mitral and tricuspid valve closing

dub sound

pulmonary and aortic valve

spleen

largest lymphoid organ

filters blood

heart attack

a condition in which blood flow to part of the heart muscle is blocked, causing heart cells to die

pain in chest, pain in left arm, nausea

heart arrhythmia

abnormal or irregular heartbeat

chest pain, fainting

coronary artery disease

major blood vessels that supply the heart become damaged/clogged by fat deposits

caused by obesity, smoking, ...

stroke

A sudden attack of weakness or paralysis that occurs when blood flow to an area of the brain is interrupted

Kawasaki disease

(inflammation of blood vessles, hence the strawberry tongue) causes coronary artery aneurysms.

redness, swelling
