Inner Systems
Inside the body, systems are constantly working together to keep us alive and in balance. Hormones regulate everything from metabolism to mood, while the nervous system sends signals between the brain and different parts of the body. The blood transports oxygen, nutrients, and hormones through the circulatory system, and the lymphatic system removes waste products and strengthens the immune defenses.
The immune system identifies and fights infections, while the endocrine system fine-tunes the body’s functions through glands such as the thyroid, adrenal glands, and pituitary gland. These systems interact in a complex yet well-coordinated whole – the body’s inner machinery that allows us to function as we should.
