Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

The human respiratory system is one of the chief and most important which is very instrumental for survival. Prime function of the respiratory system is breathing. Inhaling oxygen and exhaling carbon dioxide is all that takes plays by function of the respiratory organs. Breathing is a process by which oxygen in the air is brought in to the lungs and further in to close contact with blood. The blood absorbs the oxygen and carries to all parts of the body. Simultaneously blood gives up waste matter

Central Nervous System – brain and spinal cord 2. Peripheral Nervous System – cranial nerves and spinal nerves (relays info to/from the CNS) - Autonomic Nervous System Nerve Tissue – neurons (nerve fibers) and specialized cells (Schwann‚ neuroglia) 1. Neuron cell body contains the nucleus; cell bodies are in the CNS or trunk;

For example you will see this happen in many sports such as boxing‚ the skull protects the brain from impact of a punch during a fight. Support/ Shape: The skeletal system gives the human body structure. It supports the internal organs that are held within the body in a network of tissue. Bones give us form. In sports support and shape are also used for example in a rugby scum‚ to body needs to be placed in

When the coffee is finished‚ our coffee maker’s beeping creates pressure changes‚ which move away from the machine and radiate to the individual’s location across the room. The waves reach the outer ear‚ which contains structures known as the pinnae‚ angled such that sound waves bounce off them and resonate. They enter the auditory canal after being significantly amplified before reaching the tympanic membrane. The waves strike the membrane and cause it to vibrate‚ which subsequently transmits them

The musculoskeletal system helps the body by giving it shape and form. Without bones and muscles‚ a human would not be able to live very long because the bones protect the organs and the muscles help the body move. Although many people go through their whole life without having a single problem with this system‚ there are many diseases that make everyday life seem like just another hurdle they have to get over. A muscle disease is Central Core Disease (CDC). CDC is a rare genetic disease from birth
