The main parts of the human body are the head, the trunk, and the limbs or extremities.
The brain, the organ of thinking and the center of the nervous system, is inside the skull.
Two cavities of the trunk – the chest and the abdomen – contain many important organs. The heart and the lungs lie in the chest. The stomach, intestines or bowels, liver, gallbladder, spleen, pancreas, and kidneys are located in the abdomen.
The lower extremities called legs are made up of the thigh, shin, and foot. They are connected with the trunk by the pelvic girdle. The foot consists of the heel, sole and toes. The upper extremities called arms are made up of the upper arm, forearm, and hand. They are connected with the trunk by the shoulder girdle. We have five fingers on each hand.
The bony framework of the body is the skeleton. The bones of the skeleton are connected together by the joints, cartilages, and ligaments. The joints of the arm are the shoulder joint, elbow, wrist, and knuckles. The joints of the leg are the coxofemoral joint, knee, ankle, and others.
We have five senses: sight, hearing, smell, taste, and touch.
The organ of sight is the eye. We see with our eyes. The eyeballs are inside the orbits. The eyelids protected by the eyelashes cover them. People who see better at a distance are longsighted. Those who cannot discern distant objects are shortsighted. Blind people cannot see at all.
The organ of hearing is the ear. We hear with our ears. The internal part of the ear is inside the skull. The external part of the ear, i.e. auricle, works as a receiving chamber. People who cannot hear are deaf.
The organ of smell is the nose. We smell with our nose. One of the smaller cavities of the skull is the nasal cavity. The internal part of the nose is inside the nasal cavity. The external part of the nose consists of two nostrils and the bridge, the bony part of the nose.
The organ of taste is the tongue. We taste food with our tongue. Besides, the tongue together with the lips, teeth, palates, uvula, and vocal cords participates in the production of sounds and speech.
The organ of touch is the skin. We can touch with our skin. With the help of our skin we can feel, how touches the rough rock or the soft wool.
Two sets of teeth develop during our lifetime. The first set is 20 milk or deciduous teeth, which are replaced by 32 permanent ones of the second set later. The kinds of teeth are incisors, cuspids or canines, bicuspids or premolars, and molars.
B. A cell is the fundamental unit of every living thing. Every tissue, every organ is made up of these individual units. All cells are similar in that they contain a gelatinous substance composed of water, proteins, sugars, acids, fats, and various minerals. This substance is called protoplasm. With an electron microscope, you can see the main parts of a cell. These comprise the cell membrane, nucleus, chromosomes, cytoplasm, mitochondria, and endoplasmic reticulum.
Cells are different, or specialized, throughout the body to carry out their individual functions. Thus, there are muscle cells, epithelial cells, nerve cells, fat cells, and others.
A tissue is a group of similar cells working together to do a specific job. They distinguish epithelial tissues, muscle tissues, connective tissues, nerve tissues, and others. Different organs of the human body are structures composed of several kinds of tissue. For example, an organ like the stomach is composed of muscle tissue, nerve tissue, and glandular epithelial tissue.
Human body systems are groups of organs working together to perform complex functions. The nervous system consists of the brain, spinal cord, nerves, and collections of nerves. The respiratory system is made up of the nose, pharynx, larynx (voice box), trachea (windpipe), bronchial tubes, and lungs. The heart and blood vessels (arteries, veins, and capillaries) form the basis of the cardiovascular system. The digestive system is composed of the mouth, pharynx (throat), esophagus, stomach, intestines (small and large), liver, gallbladder, and pancreas. The reproductive system including the ovaries, fallopian tubes, uterus, vagina, and mammary glands in females and the testes, urethra, penis, and prostate gland in males is responsible for reproduction of human beings. The urinary or excretory system comprises kidneys, ureters, urinary bladder, and urethra. Besides, there are the endocrine, lymphatic, muscular, skeletal and immune systems.
