function
Transports oxygen, nutrients, hormones, and waste through the body using the heart, blood vessels (arteries, veins, capillaries), and blood.
structure of the heart
the heart has 4 chambers - 2 atriums (upper) and 2 ventricles (lower)
Blood vessels
arteries, veins, capillaries
arteries
pump blood to the rest of the body
function of the heart
the right side pumps blood to the lungs while the left pumps to the body
veins
pump oxygen poor blood back to the heart
capillaries
tiny, tin walled vessels where exchnge of gases, nutrients and waste occurs between blood and tissues
Cellular respiration
components of blood
red blood cells, white blood cells, platelets, plasma
blood pressure
The force of blood puching against the walls of blood vessels as the heat pumps
systolic pressure
pressure when the heart contracts and pumps blood
diastolic pressure
when the heart rests
(between beats)
heart rate
(BPM)
the number of times the heart beats per minute
normal range 60-100 BPM at rest
blood types
blood types are based on the pressure of absence of specific antigens on red blood cells.
main types - A,B,AB,O
transfusions
The process of transferring blood or blood components (like red blood cells, plasma, or platelets) from one person to another to treat medical conditions like anemia or blood loss.
O- universal donor (safe for all for all blood types)
AB+ universal recipient, can receive any blood type
