Low lymphocyte count is the answer to the first one I believe
and the second one i believe is valves in the veins

Answer: 1.Low lymphocyte count

Explanation:

Lymphocytes are type of white blood cells. They are important for generating immune response against the disease causing pathogens. When the count of lymphocyte becomes low the body immune system becomes weak which can make the body susceptible to diseases. Cancer is a disease which occurs in the body when the body immune system becomes severely weak. This can be said that cancer results due to low lymphocyte count.

2. Valves in the veins

Explanation: Valves are present in veins which prevents the back flow of blood. This ensures that blood flows only in one direction. Valves are not present in arteries because the flow of blood in arteries is strong and forceful that makes the blood flow in only one direction.
