Circulatory System-Red Blood Cells 58)Red blood cells are responsible for carrying: ◦59)Oxygen ◦60)Carbon dioxide These cells 61)pick up oxygen in the 62)lungs and transport it to all the body cells

Circulatory System-Red Blood Cells After delivering the 63)oxygen to the cells it gathers up the carbon dioxide It then 64)transports it back to the 65)lungs Its then 66)removed from the body when we 67)exhale There are about 68)5 million Red Blood Cells in 69) ONE drop of blood.

Circulatory System-The Blood Vessels The Blood Vessels consists of: 96)Arteries 97)Capillaries 98)Veins.

Circulatory System-Blood Vessels 99)Arteries are blood vessels that carry oxygen rich blood 100)AWAY from the heart. Capillaries are 101)tiny blood vessels as thin or thinner than the hairs on your 102)head Capillaries connect 103)arteries to veins

Circulatory System-Blood Vessels Food substances(nutrients), oxygen and 105)wastes pass in and out of your blood through the 106)capillary walls 107)Veins carry blood back toward your 108)heart
