Human beings are complex organisms made up of trillions of cells organized into various tissues and organs that work together in biological systems and subsystems. The human body contains over 20 different cell types that perform specialized functions. For example, red blood cells carry oxygen through the body while white blood cells protect against disease. Key organs like the brain, heart, and those in the digestive system are each comprised of multiple tissue types that allow them to effectively carry out critical life functions. This high level of organization from cells to tissues to organs to biological systems is what allows human beings to think, move, and survive as uniquely capable organisms.

- 1. Why human beings are complex organisms …
- 2. 1. Human beings are the unique creatures in the world. 2. Human beings has the ability to think , imagine , create and do many kinds of work. 3. Human beings are complex organisms .
- 3. The human body is made up to 100 trillion cells . Futhermore , the human body is made up of 20 different types of cells . Each of the cell in the human body has a special function . Example , the red blood cell carries oxygen to different parts of the body and the white blood cells protect our body from diseases .
- 5. 1.The human brain is the most complex organ the human body. 2. It gives us the power to think , speak , imagine and solve . 3. It handles your physical movements when you are walking , talking , standing or sitting .
- 10. 1. The human heart works in a different way . 2. The heart is the reason why we are all alive . 3. The heart transfers blood to our entire body .
- 11. The human heart
- 15. 1. The same type of cells which carry out a specific function are organised into tissues . 2. Example , a group of muscle cells form a muscle tissues .
- 16. 1 .An organ is a group of tissue that cooperates to carry out a life process . 2. Example , a group of cardiac muscle tissues , nerve tissue and blood tissue makes up the heart .
- 17. 1. A group of tissues which preform a common function make an organ . 2. Example , the salivary glands, teeth, tongue, gums, esophagus, stomach, small intestine, large intestine, pancreas, liver, gallbladder makes up the digestive system . 3. Each system consist of several organs which are organised to carry out life processes such as respiration, reproduction and digestion.
