Essay Example on ATP: Powering the Body's Nourishment Cycle

The multiple body components like the microvilli of the gut, epithelium, glucose, the circulatory system, and capillary pores effectively relate to give the body life and nourishment. Adenosine triphosphate (ATP) stores the energy that these constituents need to carry their functions. The microvilli and epithelium aid in the absorption of nutrients into the body cells and tissues. The circulatory system help in transportation of the food substances like glucose using blood flow. The fenestrations in capillaries help in efficient diffusion of glucose into the capillary walls. The essay focuses on the functions of microvilli, epithelium, capillary fenestrations, and circulatory system and how they relate with ATP, glucose and life in the body.

Microvilli are minute finger-like projections that help in improving the absorption of nutrients. The microvilli aid in the absorption of nutrients and glucose by increasing the surface area and digestive enzymes for absorption. Epithelium cells protect the inner parts of the body from infections and viruses. The absorption and epithelium cells aid in secretion and absorption of the nutrients, and transportation of the absorbed food substances to different parts of the body (Secor 12). However, these cells do not contain blood vessels and only receive sustenance from fundamental tissues through the process of diffusion. The circulatory system is responsible for the transportation of multiple substances like nutrients, glucose, hormones, and gases like oxygen in the body using blood circulation. (Holmes & Lobley 85). The interrelationship between these elements gives life, ATP, and nourishment to the individual being. The Production of ATP and glucose in the living organism is through cellular reactions, after which the circulatory system transports them to the target tissues and cells (Secor 15). Capillary fenestrations contain pores that enable molecules like gases and glucose to diffuse into the capillary walls. Vital components of the blood like glucose reach the body cells through capillary fenestrations. Due to the small size of the glucose, it freely filters out of the capillaries through the pores of the fenestrations.

Conclusion

In conclusion, the microvilli of the gut and epithelium aid in absorption of nutrients to different parts of the body. The circulatory system and the capillary pore help in transportation of the nutrients like glucose hence, shows the relationship among these components. The ATP provides energy to these constituents of body to for effective performance. Through effective absorption and utilization of nutrients, the body experiences nourishment. These processes enhance life to the body through keeping it active.
