Answers and Explanations:
The bone marrow found in the bones of the skeletal system produces both red blood cells and white blood cells (leucocytes) that enter into the circulatory system. Bood cells provide oxygen to muscles, while white blood cells travel to the integumentary system during inflammatory responses induced by cell damage or infection
Improper functioning of these systems:
- The integumentary system doesn't function properly in chronic autoimmune inflammatory conditions such as psoriasis, dermatomyositis, scleroderma and epidermolysis bullosa.
- The muscular system doesn't function properly in inherited diseases (for example, muscular dystrophy), inflammatory myopathies, chronic fatigue, etc.
- The cardiovascular system doesn't function properly in congenital heart diseases, arrhythmias, inflammatory myocarditis, coronary artery disease, etc.
- The skeletal system doesn't function properly in inherited diseases (for example, osteogenesis imperfecta), osteoporosis, osteoarthritis, etc.
Lifestyle choices that negatively affect these body systems:
1. Eat unhealthy foods: for example, a diet without calcium may lead to osteoporosis, while a diet rich in fats may lead to coronary artery diseases.
2. Sedentarim: a sedentary lifestyle increases the risk to suffer cardiovascular diseases, heart failure, high blood pressure, osteoporosis, etc.
The routine medical check-ups are essential to ensure these body systems function properly. Moreover, it has been shown that regular physical exercise helps 1-to maintain healthy muscles, 2-to avoid cardiovascular diseases, 3-to prevent osteoporosis, 4-to nourish skin cells, etc.
