    3. 3. Parts of the Digestive System
    4. 4. Parts of the Digestive System• Mouth - the first part of the digestive system, where food enters the body. Chewing and salivary enzymes in the mouth help in the breaking down the food.• Salivary glands - glands located in the mouth that produce saliva. Saliva contains enzymes that break down carbohydrates into smaller molecules.• Esophagus - the long tube between the mouth and the stomach. It uses rhythmic muscle movements (called peristalsis) to force food from the throat into the stomach.• Stomach – is a muscular organ that is attached to the esophagus. Both chemical and mechanical digestion takes place in the stomach. When food enters the stomach, it is mixed in acids and enzymes.• Liver - a large organ located above and in front of the stomach. It filters toxins from the blood, and makes bile (which breaks down fats) and some blood proteins.• Gall bladder - a small, sac-like organ located by the duodenum. It stores and releases bile (a digestive chemical which is produced in the liver) into the small intestine.• Pancreas - an enzyme-producing gland located below the stomach and above the intestines. Enzymes from the pancreas help in the digestion of carbohydrates, fats and proteins in the small intestine.• Small Intestine – bile, pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food. Most food is absorbed here.• Large Intestine - The large intestine is responsible for absorption of water and excretion of solid waste material.• Rectum - the lower part of the large intestine, where feces are stored before they are excreted.• Anus - the opening at the end of the digestive system from which feces (waste) exits the body.
    5. 5. How does the Digestive System work?
    6. 6. How does the Digestive System work? • The process starts from the mouth where the food gets break down by chewing and with the chemical reaction with the saliva. The saliva helps break down carbohydrates. The saliva (spit) has chemical enzymes which break down the carbohydrates to make it into small molecules. Then the food goes through the throat by the esophagus which has peristalsis which is wavy muscles to forces the food down to the stomach. The stomach has acids to digest the food. The liver makes bile, extracts and breaks down the fat and some blood proteins; it also helps the small intestine in digesting food. The Gallbladder stores the bile and releases the bile to the small intestine. The pancreas has enzymes which help in digestion of carbohydrates and sends fat and proteins to the small intestine. There are 2 types of intestines a small intestine and a big intestine. The small intestine breaks down food and absorbs the nutrients. The big intestine reabsorbs water and extracts solid materials to form waste. Then the feces are stored at the Rectum. Then the feces exit the body from the Anus.
    7. 7. Disorders of DigestiveSystem
    8. 8. Disorders of DigestiveSystem • Gastro esophageal reflux disease: This disease is a condition in which the food and liquid goes backwards from the stomach and makes its way to the esophagus. This will irritate the esophagus and cause heartburn and other problems. People are likely to get this disease if the consume alcohol, are obese, if they are smoking and if they suffer from Scleroderma which is a connective tissue disease. • To avoid this disease you will have to reduce the amount of caffeine, chocolate, peppermint, spearmint, and alcohol that you consume. Try to avoid carbonated drinks like Pepsi, Coke, Sprite, etc. If you have Gastro esophageal reflux disease ( GERD ), avoid eating fatty foods.
    9. 9. What is the function of the Respiratory System?
    10. 10. What is the function of the Respiratory System? • Your respiratory system is made up of the organs in your body that help you to breathe. The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. Breathing in (inhalation) fills our lungs with oxygen-containing air. Breathing out (exhalation) gets rid of the waste in our body like carbon dioxide. The organs involved in this gas exchange form the respiratory system. The respiratory system is responsible for gas exchange. This exchange of gases is the respiratory systems means of getting oxygen to the blood. The goal of breathing is to deliver oxygen to the body and to take away carbon dioxide. Remember, that Respiration = Breathing. • The respiratory system takes air into the lungs. It puts oxygen into the blood and takes the carbon dioxide out of the blood and exhales it.
    11. 11. How does the Respiratory System
    12. 12. How does the Respiratory System• Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea, which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes, which connect to tiny sacs called alveoli. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood.
    13. 13. Parts of the Respiratory System
    14. 14. Parts of the Respiratory System Organs involved are:•Larynx – Place where moving air being breathed in and out creates sounds•Trachea – This is the windpipe, or the passage leading from the mouth andthroat to the lungs•Lungs – The lungs perform respiration or gas exchange•Bronchi or Bronchus – The two main tubes of the lungs•Bronchioles – The smaller divisions of the bronchi•Alveolus – The very small air sacs where breathed in air goes•Diaphragm – Strong wall of muscle that separates the chest cavity from theabdominal cavity

    16. 16. What is the function of the Nervous System?
    17. 17. What is the function of the Nervous System? • The brain is a central computer that controls all bodily functions, and the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. The Nervous system coordinates and controls the actions of the organs and organ systems.
    18. 18. How the does the Nervous System Work?
    19. 19. How the does the Nervous System Work? • The Nervous System works by sending signals to other parts of the body. For example the brain sends a signal to the circulatory system that tells the heart to pump blood. The functions of the nervous system are done by the action of millions of nerve cells. The cells are called neurons, and they are the basic functioning cells of the nervous system. The cells (neurons) not only gather and process information but also generate proper response signals to the every part of the body. The nervous system works with every system because it spreads around your whole body. It is what tells the heart to pump, the lungs to breath. Without it the body couldnt function. The nervous system is the major controlling, regulatory, and communicating system in the body. The function of the nervous system depends on cells called neurons. These neurons carry impulses from the sensory receptors to the CNS. Sensory receptors are located in the skin, eyes, ears, tongue and nose. The nervous system basically works by neurons, or nerve cells.

    31. 31. How are Multi-Cellularorganisms organized?
    32. 32. How are Multi-Cellular organisms organized?• The multi cellular is organized from cell, tissues, organs, systems and organisms. The cells are made of organelles which carry out the function necessary for life. Cells are the smallest part of living thing. Tissues are created by a group of cells. Organs are made by groups of tissues. The organ makes systems which operate the functions of the Organism. Systems form Organisms.

    34. 34. Benefits of Multi-Cellular
    35. 35. Benefits of Multi-Cellular• The advantages of being a multi cellular organism are that it has many groups of cells, tissues and organs to perform the same functions unlike the unicellular organisms they have one cell to carry out all the functions.
    36. 36. Benefits of Multi-Cellular• The advantages of being a multi cellular organism are that it has many groups of cells, tissues and organs to perform the same functions unlike the unicellular organisms they have one cell to carry out all the functions.• If one cell of a multi cellular organism dies it has other cells which will carry out its function. If a cell of a single cellular organism dies the whole organism will die because there are no other cells to perform the function.

Unicellular organisms can only grow to a certain size because of limited cells.• Multicellular organisms are able to complete much more complicated tasks and are much more efficient at completing the simpler tasks. Each part of the multicellular organism is specifically designed to perform a specific task that they are good at it. All the parts come together and work as a whole to function. None of this exists in a single-celled organism.

    40. 40. Explain how blood is the“transportation system” for the • Blood is a liquid pumped by the heart throughout the body. Blood is a combination of plasma and cells that float in it. Blood is a specialized body fluid that supplies essentials substances and nutrients, such as sugar, oxygen, and hormones to our cells, and carries waste away from those cells. The waste is eventually flushed out of the body in urine, feces, sweat, and lungs (carbon dioxide). Blood also contains clotting agents. The main function of the blood is to transport oxygen, wastes, nutrients, minerals, hormones, blood cells and other substances throughout the body.

    42. 42. Parts of the Blood
    43. 43. Parts of the Blood• The main components of blood are:• Red blood cell- Makes up 44% of the blood and the primary function of red blood cells is to carry oxygen from the lungs to the tissues around your body. As a secondary function, they are also a key component in getting carbon dioxide waste from your tissues to your lungs, where it can be breathed out.• White blood cell- Makes up 1% of the blood and are also called leukocytes. They are part of the immune system. They help fight against diseases and infections in the body.• Plasma- It makes up 55% of the blood. It carries nutrients, waste products, hormones and blood cells. Plasma brings nourishments to the heart and takes most of the CO2 from the body.• Platelets- Makes up less that 1% and it causes blood to clot/thicken at the site of the wound to prevent blood loss. Platelets are cell fragments without nuclei that work with blood clotting chemicals at the site of wounds. For the clotting to occur, the Platelets have to work together with 13 different blood clotting factors to prevent blood loss.

    45. 45. Disorders of the Circulatory System
    46. 46. Disorders of the Circulatory System• Angina is chest pain or discomfort that usually occurs with activity or stress. Angina is chest discomfort due to poor blood flow through the blood vessels in the heart. Your heart muscle is working all the time, so it needs a constant supply of oxygen. This oxygen is provided by the coronary arteries, which carry blood. When the heart muscle has to work harder, it needs more oxygen. Symptoms of angina occur when the coronary arteries are narrowed or blocked by hardening of the fatty deposits, or by a blood clot.

    48. 48. Disorders of the Respiratory System
    49. 49. Disorders of the Respiratory System • The Respiratory system has many disorders: • Asthma is a long-term disease that makes it hard to breathe. Asthma cant be cured, but it can be managed. With proper treatment, people with asthma can lead normal, active lives. Doctors know that there are some things that make a person more likely to get asthma. If asthma is in your family history, if you live in a area higher air pollution and if your work in certain types of jobs you have a higher chance of getting Asthma. • Pneumonia is an infection of the lung that is caused different germs, including bacteria, viruses, and fungi. When you breathe in these germs, they can settle in the air sacs of your lungs. The germs may grow and overcome your bodys normal defenses. After they become infected, the air sacs then fill with pus and mucus. This swelling of the air sacs keeps oxygen from properly reaching your blood stream.
