Explain how these systems work together to support digestion, respiration, excretion, circulation, sensation, and motion
Answers
Answer:
Each organ belongs to one of ten human body systems. These body systems are interconnected and dependent upon one another to function. Your heart does not beat unless your brain and nervous system tell it to do so. Your skeletal system relies on the nutrients it gains from your digestive system to build strong, healthy bones. Each individual body system works in conjunction with other body systems. The circulatory system is a good example of how body systems interact with each other. Your heart pumps blood through a complex network of blood vessels. When your blood circulates through your digestive system, for example, it picks up nutrients your body absorbed from your last meal. Your blood also carries oxygen inhaled by the lungs. Your circulatory system delivers oxygen and nutrients to the other cells of your body then picks up any waste products created by these cells, including carbon dioxide, and delivers these waste products to the kidneys and lungs for disposal. Meanwhile, the circulatory system carries hormones from the endocrine system, and the immune system’s white blood cells that fight off infection.
Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate and blood pressure.
Even seemingly unrelated body systems are connected. Your skeletal system relies on your urinary system to remove waste produced by bone cells; in return, the bones of your skeleton create structure that protects your bladder and other urinary system organs. Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells.

Explanation:
your body is made of cells. When groups of cells do the
same kind of work, they are called tissues. The word tissue comes from a
Latin word meaning to "weave." Cells that make up tissues are sometimes
"woven" together.
2
You have four main types of tissues: epithelial, nervous, muscle, and
connective tissue. Epithelial tissue covers the outside of the body. It also
lines organs and cavities. Nervous tissue sends electrical signals. Muscle
tissue helps you move. Connective tissue joins bones and cushions organs.
3
When groups of tissues work together, they are called organs. Some
examples of organs are the heart, lungs, skin, and stomach. When organs work together,
they are called systems. For example, your heart, lungs, blood, and blood vessels work
together. They make up the circulatory system.
4
There are eleven systems in the human body: muscular system, respiratory system,
digestive system, integumentary system (skin), skeletal system, circulatory (or
cardiovascular) system, excretory (or urinary) system, reproductive system, nervous
system, lymphatic system, and endocrine system. Each system has a special job.
5
All of your body systems have to work together to keep you healthy. Your bones and
muscles work together to support and move your body. Your respiratory system takes in
oxygen from the air. It also gets rid of carbon dioxide.
6
Your digestive system absorbs water and nutrients from the food you eat.
7
Your circulatory system carries oxygen, water, and nutrients to cells throughout your
body. Wastes from the cells are eliminated by your respiratory system, your excretory
system, and your skin. Your nervous system controls all these activities with electrical
impulses. If any system in your body isn't working properly, other systems are affected.
8
Think of your body as a building. A building has a plumbing system, a heating
system, a cooling system, an electrical system, and a support system. If any system in a
building breaks down, other systems can be affected.
9
As one example, think about a building's electrical system. Suppose a mouse chewed
through an electrical wire to a furnace. Without electricity, the heating system would not
work. If this happened in very cold weather, the plumbing system could be affected.
Water pipes might freeze and burst. If a lot of water leaked into the building's walls, its
support system would be damaged. Like a building's systems, your body's systems have
to work together.
