Final answer:
Chronic disorders including liver diseases, chronic infections, and autoimmune disorders can profoundly affect the hematological system. Nutritional deficiencies, especially in vegetarians or vegans, can also impact blood health, while active lifestyles like walking regularly does not directly alter blood disorders.
Step-by-step explanation:
Chronic or systemic disorders can have a profound influence on the hematological system, which can include liver diseases such as those due to chronic infections like hepatitis or as a result of lifestyle choices such as alcoholism, as well as chronic viral or bacterial infections, and autoimmune disorders like Lupus or hypothyroidism. Conditions such as diabetes mellitus, malnutrition, hepatitis, HIV infection, and consequences of immunosuppressive treatments (like cytotoxic chemotherapy, bone marrow ablation before transplantation, or radiation therapy) can also significantly impact blood health. In some cases, nutritional choices such as maintaining a vegetarian or vegan diet without proper supplementation can lead to deficiencies that affect blood composition, such as anemia due to a lack of essential nutrients such as B12, iron, and proteins that are commonly found in animal products. However, walking 5 times a week does not directly influence blood disorders unless it is related to an overall change in health and lifestyle that could impact the hematological system.
