1ans) Human body is nothing but ,The human body is a single structure but it is made up of billions of smaller structures of four major kinds: cells, tissues, organs, and systems. An organ is an organization of several different kinds of tissues so arranged that together they can perform a special function.
2ans) The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life.
3ans) T cell, also called T lymphocyte, type of leukocyte (white blood cell) that is an essential part of the immune system. T cells are one of two primary types of lymphocytes—B cells being the second type—that determine the specificity of immune response to antigens (foreign substances) in the body.
4ans) A group of similar or dissimilar cells which performs essentially the same function and has a common origin is called a tissue.
Example of tissue : connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
5ans) Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage.
6ans) The bones of the body come in a variety of sizes and shapes. The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones.
7ans) pivot, hinge, saddle, plane, condyloid, and ball-and-socket joints
8ans) Muscles and nerve fibers allow a person to move their body and enable the internal organs to function. There are more than 600 muscles in the human body. A kind of elastic tissue makes up each muscle, which consists of thousands, or tens of thousands, of small muscle fibers.
9ans) Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream
10ans) Digested molecules of food, as well as water and minerals from the diet, are absorbed from the cavity of the upper small intestine. Most absorbed materials cross the mucosa into the blood and are carried off in the bloodstream to other parts of the body for storage or further chemical change.
11ans) The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs.In total, the rib cage consists of the 12 thoracic vertebrae and the 24 ribs, in addition to the sternum.
12ans) esophagus, stomach
13ans) The alimentary canal
14ans) Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
15ans) cardiac, smooth, and skeletal
16ans) Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive. The digestion process also involves creating waste to be eliminated.
17ans) Food enters the digestive system through the mouth. Food is broken down into smaller pieces by chewing. The teeth cut and crush the food, while it's mixed with saliva. This process helps to make it soft and easier to swallow.
18ans) After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine. Small intestine. ... As peristalsis continues, the waste products of the digestive process move into the large intestine.
