transporting substances
(animal)
componenets of blood
Plasma
Red blood
Platelets
White blood
Plasma - Transporting carbon dioxide, digested food, urea, hormones and heat
Red blood cells - Transporting oxygen
White blood cells - Ingesting pathogens and producing antibodies
Platelets - Involved in blood clotting
red blood cells do not contain a nucleus, mitochondria, or ribosomes
blood vessels
A tube through which the blood circulates in the body
arteries
Have thick muscular walls.
Have small passageways for blood (internal lumen).
Contain blood under high pressure.
veins
Have thin walls.
Have larger passageways for blood (internal lumen).
Contain blood under low pressure.
Have valves to prevent blood flowing backwards.
Capillaries
Microscopic – one cell thick.
Very low blood pressure.
structre of the heart
the heart is divided into four chambers
left and right atria
left and right ventrical
corinary heart disease
A disease in which there is a narrowing or blockage of the coronary arteries
to slow down chd you can put a stent in a vein
or you can use a vein from your leg and put in you heart
breathing
The right side of your heart receives blood from the body and pumps it to the lungs
a human breath about 22,000 times a day
gas exchange
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs
Pulmonary ventilation.
Pulmonary gas exchange.
Respiratory gas transport.
Peripheral gas exchange.
gas exchange surfaces
The exchange of gases occurs between the alveoli and blood in the capillaries that supply the lungs
Exchange surfaces are membranes that allow diffusion of substances across the membrane from a region of high concentration to a region of low concentration.
