The Systems Used by Plants and Animals to Stay Alive

The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.

The endocrine system includes of specific tissues and glands which secrete chemical messengers to the body called hormones. The glands are aided by the nervous system and chemical receptors in the blood and other hormones produced by other glands. Hormones regulate many functions of the body such as cellular metabolism, reproduction, sugar and mineral homeostasis and digestion.

The nervous system uses sensory receptors, nerves and your brain to control your cells, and acts quickly. The endocrine system uses your circulatory system and hormones to care for your cells and acts more slowly. The reproductive system and endocrine systems use hormones to function. The nervous and endocrine systems are connected by sending information to the hypothalamus and uses the autonomic nervous system to transmit what activity needs to take place in the body. This activity might be what hormones are needed, or what sensations the body feels. While the nervous and endocrine systems send information to the hypothalamus, the reproductive system receives information from the hypothalamus. So all three systems do work together, although

The digestive system are organs converting food into energy and basic nutrients to feed the entire body.

The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the

The nervous system is one of the most important organ systems in the body. It is in charge of all of the things that happen within the body. Being responsible for receiving sensory input from internal and external stimuli, integrating and processing information, and generating output, it would be hard to survive without a nervous system; however, there are different types of nervous systems in various organisms. Humans, cnidarians, flatworms, and annelids all have very diverse nervous systems. There are similarities and differences in each of these beings.

Actually, urinary system is not an isolated organ and is composed of kidney, ureter, bladder and urethra. Kidney plays the role of filtering blood, during which blood and wastes are separated. Filtered blood flow out of kidney through renal vein and wastes flow

For instance, (System, 2017) suggests kidneys are part of the urinary system which removes excess water, salts and urea. (Bbc.co.uk, 2017) suggest Urea is produced in the liver when excess amino acids are broken down. This is the main waste product removed in the urine. This links to excretion, as (Bbc.co.uk, 2017) also suggests the kidneys filter blood to remove waste and produce urine.

The endocrine system is the body system that deals with hormones and controls the body’s daily activities by producing specific chemicals. The endocrine system is also in charge of making sure that the body’s functions are coordinated and working properly. An example of this would be having the same body temperature at all times and falling asleep and waking up. Hormones play a major part in the endocrine system. Hormones are the chemical product of an endocrine gland. There are different hormones that have different jobs. Certain hormones can turn on, turn off, speed up, or slow down the activities that different organs and tissues take part in. Other hormones can regulate metabolism, growth, mood, and organ function. All of the organs involved in this body system work together but are located in different

The urinary system is made up of six organs: the two kidneys, two ureters, the urinary bladder, and the urethra. Each plays a role in excreting toxins out the body through urination. The urinary system excretes a board variety of metabolic wastes, toxins, drugs, hormones, salts, hydrogen ions, and water out of the body. In the urinary system the main focus are the kidneys. Although their primary role is excretion, they play more roles than commonly recognized. The kidneys

The nervous system is an especially complex and highly specialized network of cells that are responsible for controlling all voluntary and involuntary actions in the human body. It is also responsible for the communication between the many different parts of the body. The nervous system is divided into many subsystems, but structurally, it is comprised of the central nervous system (CNS), and the peripheral nervous system (PNS). Other functional subsystems include the enteric nervous system (ENS), the somatic nervous system (SNS), and the autonomic nervous system (ANS), which can be further divided into two components; the sympathetic and parasympathetic nervous systems.

The nervous system of the human body is an organized network of nerve cells and fibers that receive, transport, and respond to stimuli. Skeletal muscle movement involves components of the nervous system. The nervous system is an organized network of nerve cells and fibers that is subdivided into the central and the peripheral nervous systems. The central nervous system (CNS) consist of the brain and the spinal cord. This system is considered to be the information processing center of the body. On the other hand the peripheral system (PNS) is made up of the nerves and ganglia. The peripheral system is considered to be the communicator between the central nervous system and body parts. This system is then further subdivided into somatic and autonomic components. The somatic component is associated with skeletal

The urinary system helps eliminate a waste product called urea from the body, which is produced when certain foods are broken down. The whole system includes two kidneys, two ureters, the bladder, two sphincter muscles and the urethra. Urine produced by the kidneys travels down the ureters to the bladder, and exits the body through the urethra.

Without the endocrine system there to help the nervous system maintain homeostasis none of the three things listed would be possible. The functions of the two systems together are quite amazing. Within the peripheral nervous system (PNS) is the autonomic nervous system (ANS). The ANS is divided into the sympathetic or activating nervous system and the parasympathetic or calming nervous system. Both the sympathetic and parasympathetic nervous systems are activated by glands and organs within the

Digestive and Excretory Systems, and the digestive system haves you digest your food after you chew it and it breaks it down with the acid. The Excretory system is when you poop out the broken down molecules, or pee them
