The cystic artery’s function is to supply passage of oxygenated blood to the gallbladder neck and the common bile duct. 16. What is the function of the portal vein? The portal vein carries blood that contains digested food from the small intestine to the liver. 17.
There are three phases to digestion and each stage has different nerve reflexes. These three stages are the cephalic stage (for which the stimuli occurs in the head), the gastric stage (for which the stimuli occurs in the stomach) and the intestinal phase (for which the stimuli occurs in the small intestine) This essay will focus on the three phases of digestion regarding the nerve reflexes involved and how they happen. 2. THE CEPHALIC STAGE 2.1 Stimuli from head. The cephalic phase contains those stimuli that originate from the head.
Samuel Lee Medical Terminology Secition 05 Susan Elizabeth RESEARCH PAPER ON THE URINARY SYSTEM The urinary system consists of the kidneys, ureters, urinary bladder and urethra. The paired kidneys are located retroperitoneally against the posterior body wall. They receive blood from the renal arteries, filter the blood and return it to the general circulation through the renal veins. Each kidney is surrounded by a tough fibrous capsule. Within the capsule, the kidney is divided into an outer cortex and an inner medulla.
QUESTION: Trace the route of the contrast medium from its site of injection to the urinary bladder for an intravenous urography examination. NAME OF CONTRAST MEDIUM: Uroselectan (42%) TYPE: An iodinated, ionic contrast media AMOUNT INJECTED: 0.2gram per kilogram of body weight SITE OF INJECTION: 1) Right Median Cubital Vein The site of injection for an intravenous urography (IVU) examination could be the right or left cubial vein. For this study, the right median cubital vein will be utilized. This vein is located to the anterior aspect of the right elbow and connects the right basilic and cephalic veins, which run along the medial and lateral aspects of the right forearm respectively. Once access to the right median cubital vein has been gained, a bolus injection of the contrast media, Uroselectan (42%), is administered.
The sublingual glands make mucus secretions. They have only mucous acini cells. [change] Structure (How the salivary glands are built) The glands are inside a bag, called a capsule, of connective tissue. Inside, it is made of little parts called lobules. Blood vessels and nerves go into the glands at the hilum and go out into the lobules.
The mouth receives food and begins digestion by mechanically reducing the size of the solid particles and mixing them with saliva. Pharynx – The pharynx is in both the respiratory system and digestive system. The pharynx is a muscular tube, at the back of your throat when the nose and mouth join. This serves as a passageway for food and air. The tube being so muscular helps an individual with swallowing.
CheckPoint: Human Digestion I am describing, the path food follows through the digestive system and how digestion occurs in each of the following parts of the digestive system. I am including in the description of other organs or components of the digestive system, including: * Large intestine * Mouth * Small intestine * Stomach After the food enters the mouth and after being moistens and chewed by the teeth, the food then converts into a Bolus. Bolus as mentioned refers to the softened mass of munched on food that passes through the digestive system. The bolus then exits the mouth and progresses into the pharynx. The bolus then moves down into the esophagus, which follows to the stomach.
I will be looking at Mammals, Insects and Fish’s respiratory systems and how gas exchange occurs in each organism. The Lung System (Mammals) In mammals, the gas exchange surfaces are the lungs. Our respiratory system is made up of: The Larynx, formed from cartilage it is connected to the trachea (a flexible tube held open at all time by incomplete rings of cartilage). The trachea divides into two tubes on the left and right parts of the lungs called Bronchi. The Trachea continues to divide inside the lungs forming narrower tubes called the Bronchioles.
Unlike the rectum above it, the canal is liberally supplied by somatic sensory nerves, so that a poorly directed finger or instrument will produce pain. The rectum begins at the termination of the sigmoid colon about 12 cm from the anal verge .Two muscle bundles, known as the internal and external anal sphincters, participate in defecation. The internal anal sphincter is an enlargement of the circular smooth muscle of the colon and functions involuntarily. The external anal sphincter consists of striated muscle bands under the voluntary control of the puborectalis muscle. The rectum has the same innervation as the bladder; the hypogastric nerves innervate the internal anal sphincter, and the internal pudendal nerve (S3–S4) operates the external anal sphincter.
Effect on complete denture On maximum contraction of the Quadratus Labii superior the upper lip is pulled upward raising the upper lip dragging the labial gingivomucosal sulcus superiorly. This displacement of the labial vestibule might cause breakage to the peripheral seal between the vestibule and the labial flange leading to loss of the negative pressure under the denture and loss of retention causing the upper denture to drop. Another effect is that when the upper lip is elevated the lower border of
