From cells to major organ systems, the architecture of the body and the functions the body can perform are very closely related. Can you identify body cells, tissues, organs, systems that demonstrate this relationship and discuss its significance?

Answer below.

Explanation:

In the respiratory system, cells of the lungs or alveoli are made up of simple squamous epithelium and have a lot of mitochondria present in them. This helps in the function of exchange of gases and the transport of these gases to and from the body thereby fulfilling the role of the respiratory system.

The skeletal muscle cells are made up of numerous mitochondria and are spindle-shaped. The fibres form the tissues of the muscles. The mitochondria helps in the skeletal muscle's role in motion as it makes sure energy is released for this activity. The skeletal muscle fibres are arranged in such a way as to facilitate their contraction and relaxation during movement.

The cells of the small intestine are made up of Golgi apparatus and vesicles and also organelles which facilitate the absorption of food nutrients from the intestinal passage.
