The 8 Systems Of The Body
There are exactly 11 systems located in your body. The 8 major types of systems in your body are; Circulatory System, Respiratory System, Digestive System, Excretory System, Nervous System, Muscular System, Skeletal System, and Integumentary System.
The Circulatory System involves the Heart, Most Arteries, Most Veins, and Capillaries. The Heart pumps the blood throughout the body. In one day the Heart beats 100,000 times a day. There are 4 sections of the Heart called chambers. 2 of the chambers are located on the upper part of the body that are called atria. 2 others are located on the lower part of the body that are called ventricles. The Arteries carry blood that has oxygen, and nutrients through all parts of the body. The arteries then carry the blood, oxygen, and nutrients to the capillaries. The veins then carry waste products, ( for example; carbon dioxide. ) back to the heart. Capillaries are very small vessels where oxygen and nutrients leave the blood cells. Carbon dioxide, and other wastes products then enter the blood from the cells. Blood is composed of red blood cells, white blood cells, platelets, plasma, that have different functions.The main function of the circulatory system is to transport blood to all parts of the body so that gases, nutrients, and waste products are transported to and from the cells.
The Respiratory System involves the nose, trachea, bronchi, lungs, and the diaphragm . The nose collects air from the environment, moistens, and heats the air before it enters the trachea . The trachea is the windpipe that moves air from the nose to the lungs . Bronchi are tubes that moves air from the trachea to the lungs . One bronchus leads to each lung part of each bronchus, bronchus is outside the lungs and part inside . Lungs are the main organs where gases are exchanged between air and the blood. The alveoil in the lungs are where the gas exchange takes place . Diaphragm is the muscle that aids in the breathing process. The main function of the respiratory system is to provide gas exchange between the blood and the air.
e
The Digestive System includes the mouth, Esophagus, Stomach, Small Intestines, Large Intestines, and the Rectum and Anus. The Mouth works by breaking down the food and mixing it up with your saliva and starts the process of chemical digestion. Esophagus is a tube that transports, and carries chewed food to the stomach. Stomach also continues the process of mechanical digestion. Small Intestines are organs where most of the chemical digestion takes place; nutrients from food are also absorbed through the small intestines. Large Intestines are organs where water is absorbed from the food and are taken to the bloodstream. It also prepares the remaining undigested food for elimination from the body. The Rectum and The Anus are a short tube that store solid waste until it is eliminated
from the body through the Anus.
Excretory System involves the Kidneys, Ureters, Bladder, and the Urethra. Kidneys are a pair of organs. There are two Kidneys that get rid of urea, dismiss water, and other unnecessary waste materials released by the cells. They are transported through the urine. The Main Function of the Excretory System is to filter out cellular wastes, chemicals that could poison the body, and dismisses water that results from cellular respiration.
The Brain, Cerum, Cerebellum, The Brain Stem, Spinal Cord, Peripheral Nerves are all parts of the Nervous System. The Brain is an organ of the central nervous system, which has 3 parts that all play a part to control and coordinate the activities of the body. The Cerum control thoughts, and the sensations connected to the five senses. The Cerebellum helps to balance and coordinate. Brain Stem is located at the base of the brain and controls vital, the breathing,the breathing of the Heart, and the digestion. The Spinal Cord is a bundle of nerves that begin at the brain stem and goes along down the center of the back through the vertebrate. It then connects with Peripheral Nerves. Peripheral Nerves are helpful nerves that separate from the spinal cord and join the rest of the body and transport signals to and from the brain through the spinal cord. The Main function of the Nervous System are to receive stimuli from inside and outside the body, to expound the stimuli; and send responses for survival.
The Muscle System entail Skeletal Muscles, Smooth Muscles, and Cardiac Muscles. Skeletal Muscles voluntary muscles connect to bones that provide the force needed to move the bones. Tendons are connected to the skeletal muscles to the bones. Smooth muscles involuntary muscles that control many types of movement within the body. Cardiac Muscles are involuntary muscles that create the heart. The main function of the muscular system is to provide movement.
The skeletal system are bones that provide form and support for the body and also protection for many organs and structures . Some bones produce blood cells . Some store minerals . Support helps the bones in the internal framework that also supports the body and cradles its sensitive organs . Protection provides the bones to protect soft body organs such as , the skull protecting the brain , the backbone , protects the spinal cord , and the rib cage that protects the inner organs . Movement is the skeletal muscles attached to the bones by tendons , uses the bones as levers to move the body and the parts . Storage such as fat , is rich in minerals such as ,calcium , is stored in the cavities of the bones . Joints occur where two or more bones interactive . Ligaments are attached to the bones at the joints . Tendons are attached to the muscles to bones . The main function of the skeletal system are to assist the body , to protect internal organs , and to maintain attached sites for the muscles .
The Integumentary is skin that covers the body and prevents the loss of water; it keeps the body from infection and from injury. Regulates the body temperature, gets rid of waste (such as sweat), takes in information from the environment and produces Vitamin D.
