    Study Notes

    Liver Functions

    • The liver has various functions, but one of them is not mentioned.

    Respiratory Control of Acid-Base Maintenance

    • One true statement about respiratory control of acid-base maintenance is not specified.

    Kidney's Role in Acid-Base Balance

    • The kidney contributes to acid-base balance.

    Clinical Laboratory Sample Requirements

    • A sample requires 2-3 points of identification (ID) to be accepted and processed by a clinical laboratory.

    Sample Processing and Blood Ammonia Level

    • Delay in sample processing can cause an increase in the blood ammonia level.

    Order of the Draw in Blood Sampling

    • The 'Order of the draw' is necessary when taking a blood sample to maintain sample quality.

    Kidney Filtration Rate

    • The rate of filtration in the kidney depends on blood pressure.

    Plasma Proteins

    • Albumin is the major plasma protein, constituting 60% of total plasma proteins, with a molecular weight of 69kDa.

    Albumin Functions

    • One function that is not associated with albumin is not specified.

    C-Reactive Protein

    • C-reactive protein is a plasma protein that is elevated during inflammation and infections, and it falls into the category of acute-phase proteins.

    Low-Density Lipoprotein (LDL)

    • Apolipoprotein B-100 is the protein associated with human LDL particles.
