The trachea is supported by C-shaped cartilaginous rings that prevent the collapse of the tracheal wall and thereby facilitate gaseous exchange.iii. What is the smallest and simplest level of organisation?Ans: Cellular level is the smallest and the simplest level of body organisation. The tissue level can be studied when a community of similar cells form a body tissue. 2. Organs usually form to perform a specific function, which can include everything from blood movement (the heart) to waste management (the liver and kidneys) to reproduction (male and female sex organs). Our goal is to make science relevant and fun for everyone. Figure 2. Life processes of the human body are maintained at several levels of structural organization. bbe4bf5ba4ca4a8a88745893f14ae3ae Our mission is to improve educational access and learning for everyone. body 's architecture. A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. The structural levels of organization determine the different levels of development in the human body, specifically during their growth during pregnancy. The organ and organ system level organisation facilitates the division of labour and therefore brings out the several life processes working together with their maximum efficiency. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Before you begin to study the different structures and functions of the human body, it is helpful to consider its basic architecture; that is, how its smallest parts are assembled into larger structures. The red blood cells, white blood cells, and blood platelets constitute the fluid connective tissue blood and are designed according to their specific functions.RBCs lack a nucleus, ER, and mitochondria to facilitate the transport of substances.
