Explain the relationship between the hepatic artery, hepatic vein, and hepatic portal vein. Include how these blood supplies influence the vascularization of the lobule (which is the functional unit of the liver). 6. Explain what a portal triad is. Follow the output of bilirubin (which is hemoglobin waste) through the liver lobule and portal triad.
Right lymphatic duct b. Thoracic (left lymphatic) duct c. Right and left subclavian veins d. Cisterna chyli . e. Determine the direction of blood and lymph movement between arterioles, blood and lymph capillaries, and venules. Blood and lymph move between arterioles, blood and lymph capillaries, and venules through lymphatic capillaries. These capillaries are located in the spaces between cells and are closed at one end. Blood capillaries converge to form venules and then veins.
Module 05 Written Assignment - Respiration and Urinary Systems Johnetta Farmah 09/13/2013 1. Atmospheric air takes a specific pathway from the external environment to our internal lungs. Describe this pathway starting with external nares to the alveoli. What role does the trachea and surfactant play within the respiratory system? Air enters the respiratory system through the nostrils (external nares) where the air is being filtrated, warmed, and humidified.
The blood vessels are a intricate network of tubes that transport blood throughout the body. These vessels carry blood from the heart via the arteries ,then arterioles, then to capillaries or sinusoids, to venules, to veins and back to the heart. The final component to this structure is blood that delivers nutrients and removes wastes that are a by product of cellular processes that happen within the body. What is its
Food passes through a long tube inside the body known as the alimentary canal or the gastro intestinal tract (G I tract). The alimentary canal is made up of the oral cavity, the pharynx, the oesophagus, stomach, small intestine, and large intestines. In addition to the alimentary canal there are several important accessory organs that helps the body digest food but do not have food pass through them. Accessory organs include teeth, tongue, salivary glands, liver, gall bladder, and the pancreas. The first function of the digestive system is the intake of food; the mouth is responsible for this as this is where food enters the body.
When we eat our food it is broken down into nutrients then absorbed into the bloodstream, our body then discards the indigestible parts of the food, this process is called digestion. The oesophagus is a tube that passes through the chest and connects the mouth to the stomach. The stomach leads to the small intestine, which is a narrow long tube from which most of the food absorption into the bloodstream takes place. The reason why we need to digest our food is because we need various molecules from the food we eat. We need carbohydrates for energy; we need amino acids to build protein.
More saliva is produced in order to begin the procedure of breaking down food so that the body can absorb it. The pharynx receives the food from the mouth and swallowing is done here. Swallowing is partly a reflex and partly voluntary control, but the structure of the mouth is highly involved. The tongue and the soft palate push the food into the pharynx, closing off the trachea, allowing the food to enter the oesophagus. The oesophagus extends from the pharynx and behind the trachea to the stomach.
Understanding of the body organs The digestive and respiratory system (D1) When we consume carbohydrate, it is broken down in the stomach by Hydrochloric acids and passed into the small intestines. In the intestines the carbohydrate is converted into glucose and fructose. Glucose is a simple sugar and it is the main and vital source of energy. In the small intestine the glucose is absorbed by the villi (Finger like structure) . Once absorbed by the villi the glucose then travels into the blood stream.
The lungs add oxygen to the blood and remove carbon dioxide. Then the left side is responsible for accepting blood from the lungs and pumping it back out into the body. Think of it like a cycle where blood flows like this: From the body into the top right chamber (right atrium) -- down into the bottom right chamber (right ventricle) -- out to the lungs -- back to the top left chamber (left atrium) -- down to the bottom left chamber (left ventricle) -- then out to the body. The heart is innervated by the autonomic nervous system, but it also has its own system to generate electrical impulses that stimulate cardiac muscle to contract. These electrical impulses can be recorded in an ECG (electrocardiogram) and used to detect problems with the heart.
Human Respiratory system Task 1 Name of part | Function | Structural features which enable it to carry out its function | Trachea | Transports air from the throat to the lungs. | 1. Rings of cartilage to keep the trachea open for air flow.2. The trachea has cilia and mucus which trap particles and prevent them from entering the lungs, the cilia then carries the mucus to the top of the trachea where is usually then swallowed and destroyed by the stomach acid. | Bronchi and the bronchioles | Continue to transport air from the bottom of the trachea where it divides into the two bronchi; which continue to subdivide, the bronchioles, as they go deeper into the lungs and regulate air flow to the alveoli.
