The human body is mostly made up of trillions of cells, which are regarded as the fundamental unit of life. A tissue is made up of similar types of cells that perform similar activities. These tissues unite to create organs, which then form an organ system, which gives rise to an individual organism.
All living creatures, including plants, animals, birds, insects, reptiles, mammals, and humans, have organs made up of the same sort of tissues that are well-organized to fulfil specialised functions. Organ systems are made up of many organs. The structure of these organs is macroscopic. Human anatomy is concerned with the construction of the internal organs, whereas physiology is concerned with the functioning of the internal organs.
The human body contains a total of seventy-eight major organs. These organs work together to form a variety of organ systems. Five of these 78 organs are deemed essential for survival. Among them are the heart, brain, kidneys, liver, and lungs. If any of these five organs fail to operate for even a few seconds, death will occur without medical intervention. As a result, doctors usually urge us to keep our systems healthy by eating a balanced diet, getting enough sleep, engaging in regular physical activity, and focusing on healthy lifestyle modifications.
The tabular columns of 78 distinct types of human body organs are listed below.
The skin is the human body's biggest exterior organ. It is a crucial organ that provides an outer coating that protects against external factors. It also protects our internal organs from invading infections, maintains our body temperature and pH, avoids dehydration, and serves as our primary sensory organ. Skin serves as a barrier between the outside and interior environments in both animals and humans. On our body's surface, the skin covers a huge area.
The liver, which weighs between 1.3 and 1.5 kg, is the biggest internal organ in the human body. The liver is an organ found exclusively in vertebrates and is placed in the upper right part of the abdomen. It is in triangular, bilobed shape and conducts over 500 activities, including blood clotting, guarding against invading pathogens, hormone and protein production, and secretion of different enzymes and chemicals.
It is our body's most complex organ. The human brain is placed in our skull and is protected by a strong bone structure called the skull. It is suspended in a layer of fluid called cerebrospinal fluid, which protects the brain from mild mechanical shocks and jolts. The central nervous system(CNS) comprises the brain as well as the spinal cord. It is in charge of thinking, interpreting, regulating, and controlling physical motions.
The heart is one of the most important organs in the human body. The human heart continues to beat until a person dies. Our heart beats seventy times per minute, or almost forty-two hundred times per hour, and pump around 2,000 gallons of blood each day. The human heart is situated in the thoracic cavity, medial to the lungs, somewhat to the left and behind the breastbone. Two-thirds of the heart is located on the left side of the chest, with the remaining third balanced on the right side. An adult heart is roughly the size of our two palms clenched together, whereas a child's heart is around the size of a fist.
There are two lungs in the human body that are located in the thoracic cavity of the chest. Lungs are critical components of the respiratory system. A pair of lungs in humans is designed in such a way that gas exchange is facilitated. They are bordered by a thin membrane and contain bronchioles, which are smaller tubes, alveoli, which are balloon-like structures, and a collection of blood capillaries, which extend the surface area for gas exchange.
The kidneys are an essential component of the excretory system. They are bean-shaped structures that are found on either side of the backbone and are protected by the ribs and back muscles. It works by filtering extra water and eliminating potentially dangerous pollutants from the blood. Along with excretion, the kidneys generate renin, a hormone that controls blood pressure.
In the course of evolution, the human beings have evolved a very complex organ system. This holds a great importance in deciding how a human being can interact with the nature around it and works for his own betterment and also for the betterment of nature and all the organisms around. Lungs, heart, pancreas, stomach and many more are some of the most important organs of the human organ system. All the organs of the human body work together in a coordinated manner.
1. How many organ systems are in the human body and what is the small intestine?
There are almost 78 organs in the human body. The small intestine is the longest portion of the alimentary canal and a component of the digestive system that connects the stomach to the large intestine. It is narrower than the large intestine and is in charge of nutritional absorption from digested food, as well as the production of intestinal juice, bile juice from the liver, and pancreatic juice from the pancreas.
2. What do you know about te Human eye organ?
The eye is a specialised sensory organ that allows us to comprehend our surroundings. They are our body's visual sensory organs, which are sensitive to light pictures. The human eye differs from the eye of an animal. It is a spherical-shaped organ that is contained within the eye sockets of the skull and is held in place by muscles within the sockets.
3. What do you know about the human pancreas organ?
The pancreas is an essential component of the human digestive system that regulates blood sugar levels. It is an abdominal organ that is situated below the stomach and is bordered by the spleen, liver, and small intestine. It is also involved in the production of hormones such as glucagon, insulin, somatostatin, and pancreatic polypeptide, as well as the secretion of digestive enzymes into the duodenum such as proteases, amylase, and lipase.
