coronary arteries
supply blood to the heart muscle
Aorta
largest artery carrying oxygen rich blood from heart to body
pulmonary artery
transports deoxygenated blood from the heart to lungs
carotid artery
supplies blood to the brain, neck, and face
femoral artery
major artery, supplying blood to the lower limb
brachial artery
blood to the upper arm
blood pressure measurements
radial artery
blood to the lateral parts of forearm and wrists
pulse
posterior tibial artery
blood to posterior part of leg (tibia) and plantar surface of foot
dorsalis pedis artery
blood to the dorsal surface of the foot
circulation in the foot
white blood cells
Leukocyte
immune system
Red blood cell
Erythrocytes
transport oxygen from lungs to the body and CO2 from the body to the lungs
