In birds and mammals, the heart is fullypartitioned into two halves. Blood circulatesin two circuits: from the heart’s right half tolungs and back, then from the heart’s lefthalf to oxygen-requiring tissues and back.

Blood Pressure
• Highest in arteries, lowest in veins
• Systolic pressure is __________________(ventricular contraction)
• Diastolic pressure is
the lowest • Greatest pressure drop is in
arterioles
Red blood cells mustpass through capillariesin single file.
Capillary walls are thin and permeable to gases, nutrients, and cellular wastes.
