How fragile is the human body?
The human body may appear fragile but it’s possible to survive even with the removal of the stomach, the spleen, 75 percent of the liver, 80 percent of the intestines, one kidney, one lung, and virtually every organ from the pelvic and groin area.18
What type of system is used to move the body?
The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton, muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together.
Which organ systems work together to move things around the body?
Muscular System This system is made up of muscle tissue that helps move the body and move materials through the body.
Why is the neck so fragile?
The neck hasn’t completely caught up to supporting it, and it probably won’t because our bodies expend a quarter of their resources just to keep our brains alive. There’s not much left to reinforce the neck. Our brains evolved very quickly, leaving the physical support relatively weak.
Are humans flawed?
To be human is said to be flawed, limited, and finite; but to be a good human is to nonetheless struggle through and work against or despite these limitations. That we live what many consider short lives and die gives the time in our lives meaning and fuel for art, science, and creativity.
Which organ system is the most complex and fragile?
the brain
What organs are part of multiple systems?
Some organs are in more than one system. For example, the nose is in both the respiratory system and also is a sensory organ in the nervous system. The testes and ovary are both part of the reproductive systems and endocrine systems.
What is the most fragile part of the body?
The lacrimal bone is perhaps the most fragile bone of the face and one of the smallest bones in the body.20
What is the difference between organ and system?
An organ is a structure made of two or more tissues that work together for a common purpose. The most complex organisms have organ systems. An organ system is a group of organs that act together to carry out complex, interrelated functions, with each organ focusing on a subset of the task.11
What organ system does the heart belong to?
Major Organ Systems
| System | Organs in the System |
|---|---|
| Cardiovascular | Heart Blood vessels (arteries, capillaries, veins) |
| Respiratory | Nose Mouth Pharynx Larynx Trachea Bronchi Lungs |
| Nervous | Brain Spinal cord Nerves (both those that carry impulses to the brain and those that carry impulses from the brain to muscles and organs) |
Why is the human body fragile?
We’re physically fragile because being that way actually increased our chances for survival. If we were made to withstand extreme cold without freezing, we wouldn’t be able to adapt to heat when things change.
What is the most complex thing in the universe?
The brain
How does organ system work together?
Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.
What are the function of each organ system?
Organ Systems of the Human Body
| Organ System | Functions |
|---|---|
| Cardiovascular | Transports oxygen and nutrients to tissues Removes waste products |
| Lymphatic | Returns tissue fluid to blood Defends against foreign organisms |
| Respiratory | Oxygen/carbon dioxide exchange |
| Digestive | Processes foods Absorption of nutrients into body |
