What are pathogens?

A person with type AB blood can successfully receive blood from all blood types.
This is because type AB blood has both A and B antigens on the surface of red blood cells, and therefore does not have antibodies against either antigen in the plasma.
Type AB blood is also called the universal recipient.
Choice B is wrong because type AB blood can receive more than just type O blood.
Type O blood is the universal donor, meaning it can be given to anyone, regardless of their blood type.
Choice C is wrong because type AB blood can receive more than just two of the blood types. Type AB blood can receive both A and B blood, as well as O and AB blood.
Choice D is wrong because type AB blood can receive more than just one of the blood types. Type AB blood can receive any blood type without problems.
Normal ranges for blood types vary by population, but generally, type O is the most common, followed by type A, type B, and type AB.

Kidneys are not part of the lymphatic system.

The lymphatic system is a network of vessels and organs that drain excess fluid from the tissues, transport fats and immune cells, and protect the body from infections.

Kidneys are part of the urinary system, which filters blood, regulates fluid and electrolyte balance, and produces urine.

Choice A is wrong because kidneys do not have a direct connection to the lymphatic system.

Although kidneys have lymphatic vessels in their cortex, they do not originate from the lymphatic system.

Kidneys receive blood from the renal arteries and return it to the renal veins.

The lymphatic vessels in the kidney cortex drain interstitial fluid and immune cells from the kidney tissue to the regional lymph nodes.

Some additional sentences are:

Choice B is right because kidneys are part of the urinary system, not the lymphatic system.

The urinary system and the lymphatic system have different functions and structures in the body.

Normal ranges for kidney function tests include blood urea nitrogen (BUN) of 7 to 20 mg/dL, serum creatinine of 0.6 to 1.2 mg/dL, and glomerular filtration rate (GFR) of more than 90 mL/min/1.73 m.

Normal ranges for lymphatic system tests include white blood cell (WBC) count of 4,000 to 11,000 cells per microliter, lymphocyte count of 1,000 to 4,800 cells per microliter, and immunoglobulin levels of IgG (700 to 1,600 mg/dL), IgA (70 to 400 mg/dL), IgM (40 to 230

mg/dL), IgE (0 to 100 IU/mL), and IgD (0.5 to 5 mg/dL).
