Learn About The Human Body
We all only get one body, and it is important that we keep it healthy if we are going to have long and happy lives. Part of taking care of our health is understanding the different parts and systems of the body. That way, we will know how to best take care of them. Your body has a bunch of different systems, and they all work together to keep your body running.
The skeletal system is the frame that holds the human body together and keeps it safe. Consisting of our bones, cartilage, and joints, our skeletal system gives us our shape, helps us be able to move, and helps to protect many of our organs. Our brains, for example, are protected by our skulls, and our ribcage protects our heart and lungs. To keep your skeletal system healthy, it is important to get plenty of calcium in your diet, which comes from things like milk and cheese.
Attached to our skeletal system are the muscles that make up our muscular system. The muscular system is what lets us move our bodies, which happens when our muscles contract and relax. You can make your muscles stronger with a healthy diet and exercise. That is why you often see people encouraging a good diet and exercise that includes at least some moderate weight-lifting: Exercising with weights can make your muscles stronger.
The muscular and skeletal systems, as well as other body systems, are controlled by our nervous system. The nervous system includes our brain, spinal cord, and nerves. Signals from the brain travel through our nerves to make our bodies work. The reason why helmets are required for certain sports is that they help protect your brain from damage that can keep you from being able to walk, talk, or lots of other important things you do every day.
The urinary system takes waste out of the body and gets rid of it through urine. The kidneys filter the blood and make urine, which is stored in the bladder until you go to the bathroom. Sometimes, the urinary system is described as part of the excretory system, which also includes the integumentary system. The integumentary system is made up of our skin, hair, and sweat glands. It protects our internal organs and helps cool our bodies when we sweat. Drinking plenty of water is vital to the health of our integumentary system.
The endocrine system is made up of glands that make hormones to regulate things like your growth. It is closely tied to our reproductive system, as several of the hormones related to reproduction and the development of the human body are made by the testes and ovaries. The hormones produced by the endocrine system also work hand in hand with the nervous system to cause movement and other bodily functions.
Two other body systems that are closely related are the respiratory and cardiovascular systems. The cardiovascular system includes the heart and blood vessels, including capillaries, veins, and arteries. The heart pumps blood through the body via the blood vessels, and the blood carries oxygen and nutrients to the organs. Blood gets oxygen from the respiratory system as air enters the lungs, which help bring oxygen into the bloodstream.
Finally, the digestive system is the part that takes in the fuel your body needs to run. It includes our esophagus, stomach, small intestine, large intestine, liver, pancreas, mouth, tongue, and teeth. Food that we chew in our mouths passes through the system, which extracts proteins, carbohydrates, water, and other nutrients for use in the body. The large intestine functions also as part of the excretory system, as waste material from the food we eat passes through the large intestine and out of the body.
