  9. 9red blood cells are formed in [blank_start]bone marrow.[blank_end] Red blood cells remain functional only for a limited time before they are broken down and replaced. Worn out cells are taken up by [blank_start]phagocytosis[blank_end] by [blank_start]macrophage cells[blank_end]. This occurs in phagocytes called [blank_start]Kupffer cells.[blank_end] Kupffer cells are attached to the walls of [blank_start]sinusoids[blank_end]. The globin ([blank_start]protein part[blank_end]) and [blank_start]haeme[blank_end] (non-protein part containing Fe ions) are split apart. The globin is [blank_start]hydrolysed[blank_end] by [blank_start]proteases[blank_end] to [blank_start]amino acids[blank_end]. Iron in the form of [blank_start]Fe3+[blank_end] is formed in the breakdown of the haeme. Fe3+ is removed and attached to a [blank_start]carrier protein[blank_end]. Iron is stored in the liver cells and eventually exported via the [blank_start]blood plasma[blank_end] to the bone marrow. The remainder of the haeme part is converted into [blank_start]bile pigments[blank_end] and secreted into [blank_start]bile channels[blank_end] between the [blank_start]sinusoids.[blank_end]
