The purpose of the skeletal Muscles: Is to enable humans to move and do their daily activity for example going to school or work.

The purpose of smooth Muscles: Is to help with Digestion and nutrient collection and it is found Throughout the urinary system.

The purpose of the Cardiac Muscle: The cardiac muscle is in charge of the Pumping action in your heart.

The purpose of the Tendons: The purpose of a tendon is Facilitating the movement around a joint.

The purpose of Muscles pair: One muscle of the pair contracts to move the body part. Then the other muscle in the pair then contracts to return the body part back to the original position.

The purpose of the axial muscle: The purpose is to support and position of the Axial skeleton.

The purpose of the Appendicular Muscles: Is to brace the limbs and support and move them.

How they work together: Tendons connect the skeletal system to the muscular system by attaching muscle to bone. When muscle contracts the tendon acts on the bone, causing movement. Joints, the point at which two or more bones connect can be fixed by slightly movable or freely movable.

The analogy: The Muscular system is like a car: In a car the engine is very similar to the muscular system. They both help their systems to move without them the car or body would not operate.

What is the purpose of the nose: The nose gives you a sense of smell

What is the purpose of the mouth: Your mouth is for eating and speaking.

What is the purpose of the throat: The throat acts as a passageway for air food and liquids.

What is the purpose of the voice box: The voice box is for swallowing, breathing and voice production. Another word for the voice box is Larynx.

What is the purpose of the lungs: The lungs allows us to breathe.

What is the purpose of the Diaphragm: The Diaphragm helps you inhale and exhale aka breathe in and breathe out.

How they work together: The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide

Analogy: Think of your respiratory system as an upside-down tree. When air enters your body, it goes down your trachea. That's the trunk. Then it quickly divides into two airways which is the trees limbs.

Brain

The brain controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.

Spinal Cord

The spinal cord connects your brain to your lower back, and sends motor commands from the brain to the body.

Cerebellum

The cerebellum helps the human body to maintain balance.

Somatic Nervous System

Its primary function is to control voluntary movements and reflex arcs, while still helping us process our 5 senses.

Autonomic nervous system

It regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, etc.

Sympathetic Nervous System

It Helps the brain respond to dangerous and stressful situations.

Parasympathetic Nervous System

It helps the brain and body cool down after a dangerous or stressful situation.

How they work together: The nervous system uses tiny cells called neurons to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network. Different neurons have different jobs.

Analogy

The nervous system is like a giant telephone system. What makes memories, thoughts, vision, speech, and hearing.

What is the purpose of the mouth: The mouth is for eating and speaking.

What is the purpose of the esophagus: The purpose of the esophagus is to transport food entering the mouth through the throat and into the stomach.

What is the purpose of the stomach: The stomach holds the food and mixes it with acid and enzymes that continue to break the food down into a liquid or paste.

What is the purpose of the pancreas: The pancreas is an organ of the digestive system and of the endocrine system. The exocrine pancreas produces enzymes that help to digest food, particularly protein. The endocrine pancreas makes the hormone insulin, which helps to control blood sugar levels.

What is the purpose of the liver: The liver processes blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

What is the purpose of the gallbladder: Your gallbladder is part of your digestive system. Its main function is to store bile. Bile helps your digestive system break down fats. Bile is a mixture of mainly cholesterol, bilirubin and bile salts.

What is the purpose of the small intestine: The principal function of the small intestine is to break down food, absorb nutrients needed for the body, and get rid of the unnecessary components. It also plays a role in the immune system, acting as a barrier to a multitude of flora that inhabits the gut and to make sure no harmful bacteria enter the body.

What is the purpose of the large intestine: The large intestine has 3 functions absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.

How they work together: The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.

Analogy: The stomach is like a washing machine because it mechanically churns bolus, chemically combines food with pepsin and hydrochloric acid and breaks down protein, just as a washing machine mixes the clothes mechanically and blends them with cleaning detergent.

What is the purpose of white blood cells: They circulate in the blood and mount inflammatory and cellular responses to injury or pathogens.

What is the purpose of the red blood cells: A type of blood cell that is made in the bone marrow and found in the blood.

What is the purpose of the heart: Your heart is the main organ of your cardiovascular system, a network of blood vessels that pumps blood throughout your body.

What is the purpose of the Arteries: Arteries are blood vessels that distribute oxygen-rich blood to your entire body.

What is the purpose of veins: Veins are any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.

What is the purpose of the lymph: Lymph is a clear-to-white fluid made of: White blood cells, especially lymphocytes, the cells that attack bacteria in the blood and body tissues.

What is the purpose of the Atrium: The atrium is the heart chamber that receives blood into the heart and drives it into a ventricle, or chamber, for pumping blood away from the heart.

What is the purpose of valves: A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category.

How they work together: The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.

Analogy: The heart as the city pump, the aorta as the water tower, arteries as parallel distribution pipes, and arterioles as faucets.
