The Respiratory System
The respiratory system is a network of organs and tissues that work together to help you breathe. The main function of the respiratory system is to supply the body with oxygen. When you inhale (breathe in), air enters your lungs and oxygen from the air moves into your blood. The oxygen-rich blood is then pumped by your heart to the rest of your body.
The Cardiovascular System
The cardiovascular system is responsible for taking oxygen-rich blood to the body’s tissues and carbon dioxide-rich blood back to the lungs. The heart pumps blood through a system of vessels, including arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart to the body’s tissues. Veins carry carbon dioxide-rich blood back to the heart. Capillaries are tiny vessels that connect arteries and veins and allow exchange of oxygen and carbon dioxide between the blood and tissues.
The Lymphatic System
Your lymphatic system is a network of vessels and nodes that helps clear away infection, remove waste products from your cells, and produce immune cells. It’s an important part of your body’s defenses, but it doesn’t have a pump like your heart to keep things moving. So how does lymph travel through your body?
The answer has to do with the movements of your muscles and the pressure changes that occur when you breathe. When you contract your muscles, they push on the lymph vessels and help to move the fluid along. The valves in the lymph vessels also help to keep things flowing in the right direction. And as you breathe, the changes in air pressure help to push the lymph fluid up towards your chest, where it can drain into your blood vessels.
The Immune System
Air travel can have a number of effects on the body, and one of the most important is its impact on the immune system. When we fly, we are exposed to a number of different pathogens and bacteria that can weaken our immune response. In addition, the pressurized cabin and dry air can also lead to dehydration, which can further reduce our ability to fight off infection.
There are a few things you can do to minimize the impact of air travel on your immune system. First, be sure to drink plenty of water before and during your flight to stay hydrated. Second, avoid touching your eyes, nose, or mouth while in the airport or on the plane. And third, wash your hands often, especially after using the restroom or handling any food. If you follow these simple steps, you can help keep your immune system strong and reduce your risk of getting sick while traveling.
The Digestive System
The digestive system is a group of organs that work together to break down and absorb food.
The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
The liver, pancreas, and gallbladder are also part of the digestive system because they make juices that help digestion.
digestive system
The mouth is the first part of the digestive system. The mouth is where food enters the body.
The teeth break food into small pieces.
The tongue mixes food with saliva. Saliva is a liquid made by the salivary glands. Saliva contains enzymes that begin to break down carbohydrates in food.
The esophagus is a tube that connects the throat to the stomach. The esophagus moves food from the mouth to the stomach in waves of muscle contractions called peristalsis.
Peristalsis is when muscles contract to push food or liquid through a tube.
The stomach is a J-shaped sac located between the esophagus and small intestine. The stomach stores swallowed food and begins digestion by breaking it down with gastric juice. Gastric juice is made up of water, mucus, hydrochloric acid, enzymes, and electrolytes. The hydrochloric acid kills bacteria and other organisms in swallowed food. Hydrochloric acid also starts to break down proteins in food so that they can be used by the body. Enzymes in gastric juice continue to break down carbohydrates, fats, and proteins into smaller molecules that can be absorbed into the bloodstream.
Most digestion takes place in the small intestine . The small intestine is about 20 feet (6 meters) long and has three parts: duodenum , jejunum , and ileum . Each part has a different function in digesting food:
Duodenum – Food enters from the stomach and mixes with bile from the gallbladder and enzymes from pancreas . Bile is a yellowish-green liquid produced by liver cells which helps digest fat . Pancreatic enzymes complete protein digestion begun in stomach . Many chemical reactions take place here as well as absorption of some nutrients such as water , electrolytes , vitamin B12 , iron , copper , magnesium , some fats , and some minerals .
Jejunum – Here most carbohydrate digestion takes place as well as some protein digestion along with fat absorption . Water , electrolytes , vitamins ( except for B12 ), minerals , sugars such as glucose & fructose are all absorbed here .
Ileum – This section of small intestine completes absorption process started in duodenum & jejunum for vitamins ( except for B12 ), water , electrolytes , sugars such as glucose & fructose , minerals along with some amino acids & fats ( fatty acids & monoglycerides ).
The Urinary System
The urinary system is responsible for removing waste from the body in the form of urine. The kidneys filter the blood and remove excess water and waste products, which are then excreted in the urine. Urine travels from the kidneys through the ureters to the bladder, where it is stored until it is excreted through the urethra.
The urinary system also helps to regulate blood pressure and maintain fluid balance in the body. When you are dehydrated, your kidneys will reabsorb more water from your urine to help maintain fluid levels in your body.
The Reproductive System
The reproductive system is a vital part of the human body and is responsible for the creation of new life. The system is made up of a number of different organs, all of which work together to produce and sustain new life.
The primary organs of the reproductive system are the testes in males and the ovaries in females. The testes produce sperm, which are tiny cells that carry the male genetic material, while the ovaries produce eggs, which are larger cells that carry the female genetic material.
When a sperm fertilizes an egg, the resulting cell is called a zygote. The zygote divides into smaller and smaller cells, eventually developing into a fetus. The fetus grows inside the mother’s womb until it is ready to be born.
The Nervous System
The nervous system is responsible for sending messages throughout the body. These messages are sent through a system of nerves, which are made up of neurons. Neurons are cells that communicate with each other through electrical impulses.
The nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and the spinal cord. The peripheral nervous system consists of all the nerves that branch off from the spinal cord and connect to different parts of the body.
Air travel through the body begins when we take a breath in. The air travels through our nose or mouth and down our throat into our lungs. Our lungs are made up of tiny sacs called alveoli, which are surrounded by tiny blood vessels called capillaries. When we breathe in, the air passes through the alveoli and into the capillaries.
The oxygen in the air enters our blood stream and is carried to different parts of our body by red blood cells. The red blood cells deliver oxygen to our muscles, which use it to produce energy. The carbon dioxide that is produced by our muscles is carried back to our lungs by red blood cells and exhaled when we breathe out.
The Endocrine System
Your endocrine system is responsible for producing and releasing hormones into your bloodstream. These hormones regulate your metabolism, growth, and many other vital functions. Your endocrine glands produce these hormones, and they include the pituitary gland, thyroid gland, adrenal gland, pancreas, ovaries (in females), and testicles (in males).
The Skeletal System
The human skeleton is made up of 206 bones. It provides the framework for our bodies, protects our vital organs, helps us move, and stores minerals and fat. Our bones are constantly being renewed — a process that requires minerals from the food we eat.
The skeletal system includes all of the bones in our bodies as well as organs such as the liver and spleen, which are protected by the skeleton. Bones are made up of living tissue called bone marrow. This tissue is made up of cells that produce new bone cells.
One of the most important functions of the skeletal system is to provide support for our bodies. Without our skeleton, we would be a blob on the ground. The skeletal system also protects our vital organs — the brain, heart, lungs, and other internal organs — from injury.
Another important function of the skeletal system is to help us move. Our bones are attached to muscles, which contract and relax to create movement. Joints also play an important role in movement — they allow our bones to move in different directions so that we can bend and twist our bodies.
The skeletal system also stores minerals such as calcium and phosphorus, which are essential for healthy bones and teeth. Fat cells are also stored in bone marrow. These cells help insulate our bodies and provide energy reserves during times of starvation.
