The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system. The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body! The skin has 3 main function. It has to regulate body temperature, remove waste (perspiration), and protect. The skin is made up of 3 layers. The epidermis is the outer thinner layer of the skin that is made up of dead and living cells. The dermis is the thicker middle layer of the skin that contains blood vessels and nerves. Sweat glands are found in the dermis, they secrete perspiration through ducts to pores on the skin’s surface. To avoid problems like warts, boils, moles, acne, and sunburn you can wash your body daily, wear sunscreen that is 15 or higher, and check your body often... ... middle of paper ... ...culatory system. Pituitary gland is a growth hormone that helps in mertabolism and develops reproductive organs. The thyroid controls metabolsim on the rate that the body breaks down food. Adrenal gland secretes many hormones including adrenaline which prepares the body to react in a stressful situation. The pancreas produces digestive enzymes and insulin. Ovaries produce ova and estrogen. Testes produce sperm cells and testosterone. To stay healthy you should get a regular medical check-up, eat a well-balanced diet, sleep at least 8 hours, and decrease stress in your life. Some problems are growth disorders, diabetes, and obesity. Puberty begins at different times for girls then boys. Girls start around ages 9-13 and boys are ages 10-15. The body is an amazing thing. So many things are going on at once. Without your eyes you wouldn’t be able to see this paper!
The integumentary system has five main functions. The five main functions of the integumentary system are protection, regulation, sensation, absorption, and secretion. It consists of the hair, nails, skin, sebaceous and sweat glands. The largest organ of the entire body is the skin. The skin consists of three different layers. The epidermis, the dermis, and the subcutaneous layer, these are the three layers of the skin. There is a layer that is deeper than the skin and contains body fat, that layer is called the hypodermis. Sweat glands are also called sudoriferous glands. One of the functions of the skin is to maintain homeostasis. Synthesis of vitamin D, excretion of urea, excretion of salts and water are a few things that the skin is also capable of. The top layer of the skin is called the epidermis. The epidermis contains five different layers. These layers are the stratum corneum, the stratum lucidum, the stratum spinosum, and the stratum basale. In the epidermis there are four different cell types. The keratinocytes which produce keratin, the merkel cells that are sensitive to touch, the langerhans cells which is a dendritic type off cell, and the melanocytes which produce melanin.
All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this system.
The nervous system controls both voluntary action (like conscious movement) and involuntary actions (like breathing) and sends signals to different parts of the body. The central nervous system includes the brain, spinal cord, sensory organs, and all of the nerves that connect these organs to the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center, also known as the central nervous system, where information is
Our nervous system interacts with every other system in your body. The endocrine system works with our brain and central nervous system, to control the creation of specific hormones and enzymes. The digestive and excretory systems work with the nervous system in a conscious and unconscious ways. We can't tell our stomach where the food goes after we ingested it. The body is programed to function voluntarily and
The human body is, in its simplest observation, an extensively vast web of cells. The human body is one of the most complex productions in the world. Looking at just one part of the body such as the eye makes it apparent the complexity of the body’s makeup. The body is comprised of cells that come together to make tissues. These tissues fit together to make organs. The organs coexist to form organ systems. These organ system make up the entire organism that is man.

The nervous system is a network of cells that take messages from the brain and spinal cord to other parts of the body. The nervous system is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System has two main parts; the brain and the spinal cord. While the Peripheral Nervous System has the Somatic and the Autonomic Nervous systems included within it.
Almost all animals have a nervous system. Neurons bundle together to form nerves. The purpose of the nervous system is to coordinate all activities of the body, and enables the body to respond and adapt to changes both inside and outside. The central nervous and the peripheral nervous systems are very similar but different at the same time. The CNS is made up of the brain and spinal cord and functions mainly to process information and determine the appropriate responses. The central nervous system receives sensory information, figures out a response, and initiates a motor response if appropriate. The CNS is protected by the skull, vertebral column, and a membrane. The spinal cord provides communication between the brain and the peripheral nerves
The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells that sends information to the brain to be analyzed.
Together, the systems keep the body informed about the outside world through the sense organs and manage our reactions regarding the external stimuli. The three systems also regulate internal activities such as breathing, beating of the heart, and absorption of water in blood by the kidneys. Through the hippocampus, the part of the brain that links the nervous system and endocrine system, input from the sensory system is converted into actions. In other words, the systems make our bodies work together in proper coordination, as one single integrated
The body works in amazing ways like a fine tuned machine. All organ systems within the body depend on one another for survival in some way or form at all times. Cherif et al., (2010) state, the body depends on the precise action of each organ to maintain physical, mental, and emotional health of a human being. Also, homeostasis, the regulatory of body temperature plays a survival role in maintaining body functions. The integumentary system (skin) is the largest, and the most important part of the body. The skin is just one of the organ systems that will be discussed (Thibodeau & Patton, 2008). The body is expected to perform specific duties at specific times the organ systems as a whole, the most important organ system the integumentary system, and homeostasis, are what enables the body to perform on demand.
Since the brain and the nervous systems are in need of each other to perform their functions it is important to look at the brain and all of it 's features. The brain is the control center that process the majority of all the bodies functions. The spinal cord is responsible for certain simple muscle reflexes but the brain process both conscious and unconscious.
The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
Every organ in the human body is composed of one or more tissues. The study of these tissues is known as histology. It is because of histology that the structure of organs can be researched and understood. Since organs are composed of tissues, it is important to understand each tissue type, their structure, their location, and their functions to better understand how each organ operates within the human body.
