THE BODY SYSTEMS(not all)

There are seven systems or more which are responsible for every part of our body. Every system have particular use, such as for breathing, blood circulation, food digestion, waste excretion, locomotion and our movement, reproduction and for our memory, intelligence and reasoning. These different systems are classified as respiratory system, reproductive, circulatory, digestive system, excretory, skeletal, muscular, and nervous system. Each system should work together to let our body work. If one of the systems won’t able to work, our body won’t function well and hardly help our body to do its job, because every part of each system is important.
Circulatory system is a system which is liable for pumping blood throughout our body and transport nutrients and oxygen for our cells to help other organs to function. Some organs in this system are heart, blood, arteries, veins, and capillaries. Blood is one of the main prop for the circulatory system; there are three types of blood the red blood cell, white blood cell plasma and platelets. The red blood cell is a kind of blood which is responsible for carrying the nutrients and oxygen to the different parts of our body, the white blood cell is the one that assists fighting foreign bodies and protect our body from diseases, Plasma is the liquid component of our blood, and lastly the platelets, platelets are responsible for blood clotting, preventing and healing. Our blood became red because of hemoglobin which is the red pigment in our blood and it carries oxygen. Our blood have three colors, white, blue and red, red if it’s oxygenated, white for the white blood cells, blue for deoxygenated blood.

Respiratory System is the system responsible for our breathing in and out of oxygen and carbon dioxide. Some organs in this system are, nose, mouth, pharynx, larynx, trachea and bronchi. The breathing process starts in our nose/mouth, then passes through trachea or wind pipe, afterwards it will pass into two branches called bronchi, one for every lung. The bronchi are followed by more branches called the bronchioles, at the end of every bronchioles there is an air sac made up of tiny formations called alveoli, our alveoli are surrounded by dense network of small blood vessels called capillaries, then the blood will pick up oxygen, after that the circulatory system will take over and distribute the oxygen into body parts which need oxygen. Respiratory system and circulatory system work together to help our bode work.

Digestive system’s function is to break down food into smaller particles to feed our body cells. The organs found in this system are, stomach, esophagus, mouth, teeth, pancreas, small and large intestines, appendix and anus. The digestive tract goes like this, it starts with our mouth chewing bolus, then the bolus passes through the esophagus, afterwards it reaches the stomach and the bolus becomes a chyme, then the chyme travels to the small intestine, then to the large intestine, going to the rectum, ended in the anus.

The muscular and skeletal systems are the one which protects our body and other body parts, it’s also used for our locomotion and movement. The skeletal system does give our body shape because it’s the frame work of our body. In the skeletal system it includes, bones, cartilage, ligament and joint. Our bones also produce white, red blood cells, platelets and plasma. Our muscular system can be found anywhere in our body, our stomach, heart, have hallow muscles to function.

Excretory System is responsible for elimination of nitrogenous waste products, produces, stores and elimination of urine and urea. The excretory system does only excretes it also secretes, egests, and eliminates waste. Some of the organs in this system are skin, liver, kidneys, bladder, urethra and etc. This system eliminates waste through lungs, kidneys and large intestines. The some of the waste products are salt, water, urea, carbon dioxide, and heat.

Each and every part of our body system and its organ are really important in our sensitive body. Each has its individual use but every part has a connection. All the system should collaborate to let our body work and function well. Circulatory system is connected to the respiratory system and the respiratory system works with the excretory system, and the digestive system needs the excretory system to excrete the waste from the food we take then the Skeletal and Muscular system to protect the organs in circulatory, respiratory, digestive and excretory system.
