|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




fluid distribution between capillaries and tissues, and transport protein for water-insoluble
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




molecules

, Plasma pH Buffering System - correct answer✔✔1. CO2 removed from tissues is hydrated in
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




plasma to form carbonic acid, which dissociates to form bicarbonate ion and a hydrogen ion
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




2. The bicarbonate ion is transported to the lungs and is dehydrated back into CO2 and H2O
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




3. Hydration and dehydration conversions of CO2 are facilitated by carbonic a hydrate
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




4. Blood pH is balanced by the presence of both carbonic acid and its conjugate alkaline,
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




bicarbonate.

5. Bicarbonate ion serves to neutralize excess acid introduced to the blood
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




6. Carbonic acid serves to neutralize excess alkaline introduced to the blood.

|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




2. Body's primary transport medium
|||\\\ |||\\\ |||\\\ |||\\\




3. Transports O2/CO2 to and from tissues
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




4. Transports nutrients, hormones, and vital bio molecules to tissues
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




5. Transports immune cells and immune proteins
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




6. Transports waste products to the kidneys and liver for elimination and/or recycling
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




7. Regulates pro and anticoagulation pathways
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\




8. Regulates body temp
|||\\\ |||\\\ |||\\\




9. Regulates blood pH
|||\\\ |||\\\ |||\\\




RBC - correct answer✔✔Erythrocytes
|||\\\ |||\\\ |||\\\ |||\\\




WBC - correct answer✔✔leukocytes
|||\\\ |||\\\ |||\\\ |||\\\




Platelets - correct answer✔✔Thrombocytes |||\\\ |||\\\ |||\\\ |||\\\




RBC - correct answer✔✔1. ~99% of cellular component in the blood
|||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\ |||\\\




2. Formed by BM-HSCs
