Learn body system functions with free interactive flashcards. They control your heartbeat … The major structures of the urinary excretory system include the kidneys, urinary bladder, urethra, and ureters. All blood is passed through the kidneys, where structures filter out dangerous substances and excess water while retaining useful substances. The skeletal system is the framework of our body. Then, it passes by intestines, squeezed by a huge area of a narrow tube of intestine to ensure that many useful materials extracted by the food as possible. Functions that must be performed by an animal to stay alive include: Additionally, for a species to survive, its individuals must be able to reproduce. Body Parts: endocrine system – students look closely at the human endocrine system. The skeletal muscle is best adapted to short bursts of strenuous exercise. The blood in veins moves a bit slower and at lower pressures. Human body internal parts such as the lungs, heart, and brain, are enclosed within the skeletal system and are housed within the different internal body cavities. 1.3 Work with knowledge of the major components of each body system and their location in relation to other structures. Other organs and tissues serve a purpose in only one body system. It maintains the balance of fluid between the blood and tissues, known as fluid homeostasis. The cardiac muscle surrounds the heart and performs important function in the circulatory system. The respiratory system takes oxygen from the environment to be used throughout the body. The lymphatic system is a circulatory system separate from the cardiovascular system. This is the primary reason that heart attacks are deadly. Without enough sleep, your immune system might not be able to function at its best. It is responsible for the removal and … Without oxygen to fuel cellular respiration, cells begin to die within minutes. Therefore, our skeleton also protects our most vital organs. The skin is a surprisingly complex material, which scientists have not been able to reproduce artificially. The human muscular system is complex and has many functions in the body. The urinary or excretory system filters and discharges excess fluid or other harmful substance streamed through the blood. The reproductive system facilitates the production of offspring.

Guyton and Hall: Textbook of Medical Physiology. Giving the body its shape is the skeleton, which is composed of cartilage and bone. It all can be used by cells as a source of energy. In the case of animals, we have white blood cells that can specifically target and destroy invading pathogens. The cardiovascular system functions to transport oxygen and nutrients to tissues and removes waste products. The heart pumps the blood and the arteries and veins transport it. Biologydictionary.net Editors. It does not carry red blood cells and platelets, because it is not main carrier of the body for oxygen, lymph moves slower than the bloodstream. The human body contains trillions of cells, which fall into several types – nerve cells, muscle cells, fat cells, liver cells, and so on – each with a different function. In a few cases, these muscles can be controlled voluntarily, but smooth muscle is generally controlled by the subconscious or autonomous nervous system.
