The urinary system consists of 4 major organs; the kidneys, ureters, urinary bladder and the urethra.Together these organs act to filter blood, remove waste products, create urine and transport urine out from the body. In other words, cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make an organism. Each lung is located in a body cavity called a pleural cavity. 41A, RS : 633-634 Urinalysis (OMIT : sediment analysis); 628-631 Test : prepared "pathologic" urine specimens. Urinary System Anatomy. Observe how the diaphragm attaches to the body wall and separates the abdominal cavity from the lung (pleural) and heart (pericardial) cavities (figure 16 and 18 below). The pericardium is a membrane that surrounds the heart and lines the pericardial cavity. Colon, horn of uterus, ovary, urinary bladder, Figure 50. Hypoxia is when you are low on oxygen. This structure stores bile produced by the liver. The characteristic mix of agglutinates and free red blood cells (RBCs), caused by anti-Sda, is seen with the RBCs from 90 percent of individuals of European descent. The endoderm transforms into the lungs, trachea, thyroid gland, and digestive tract of the fetus. The Urogenital system is the organs of the pig associated with urinary excretion and reproduction. Follow the trachea to where it branches into two bronchi and observe that each bronchus leads to a lung. You will then dissect a sheep kidney in order to observe the internal structures of a kidney. The amount of floor space has been shown to impact the time it takes gilts to reach puberty. The forelegs of the frog and fetal pig are also considered a part of the anterior end. Fetal Pig The Urinary System 5.0 (1 review) Kidneys Click the card to flip Def: Main organs of the urinary system, 2 bean shaped organs Location: On either side of the spine covered by peritoneal membrane Function: Excretes waste products and regulates water and salt balance to form urine Click the card to flip 1 / 6 Flashcards Learn Test Match The development of the penile urethra in the pig. It contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural (lung) cavity. This allows blood to pass directly from the right to left atrium. We determined the morphological characteristics of the renal excretory system in pigs. Use a probe to separate the two lobes of the thymus gland and to further separate the musculature over the trachea. The base of the liver opens into the hepatic hilum, which is but the entrance area of the omentum (omentum) lower with the portal vein, hepatic artery and hepatic duct outlet. Suburban Science. Penis, scrotum, urogenital opening, Figure 52. Find the posterior part of the large intestine called the rectum and observe that it leads to the anus. The one main difference is the size of the organs. Esophagus, larynx, trachea, bronchus, and lung. Review of the urinary and reproductive organs. The thyroid gland is darker and lies between the posterior ends of the two lobes of the thymus gland. Leading away from each testis is a vas defrens tubule that will merge with the urethra directly below the urinary bladder. Colon, body of uterus, horn of uterus, ovaries, urethra, urinary bladder, urogenital sinus, Figure 51. 61. Open the jaw wide enough so that the glottis and epiglottis are exposed.

Tie one front leg of the animal with a string that passes underneath the dissecting pan to the other leg. Anatomy of the Urinary System : Ex. For example, when a dancer lands after a vertical jump, the force exerted on the head by the neck must exceed the heads weight by enough to cause the head to slow down and come to rest. So as to comprehend this diagnosis, I am going to paint you a picture of human throat structure. These two cuts will enable you to spread open the abdominal cavity. Pigs, as a mammalian species, provide a good specimen for the study of physiological systems and processes due to the similarities between many pig and human organs. They are both extremely dark red, with a tint of brown. 4. Fetal Pig Internal Practical.

The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. The cells begin to specialize by day six, and attach themselves to the uterus lining by day eleven. An incision was made on the side of the neck to enable the injections. The word "urogenital" refers to an opening that serves both the urinary (excretory) and the reproductive systems. They argue that the research supports abortions but have taken part in receiving vaccines and therapy that comes from the research. There are only a few differences between the circulatory system of an adult pig and a fetal pig, besides from the umbilical arteries and vein. The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. Continue cutting from the anterior end of this cut so that it resembles an upside-down U. The flap of body wall that contains the navel can be folded posteriorly to reveal the internal organs of the abdomen. In males, the UG sinus is divided into three regions: upper, pelvic, and phallic.

The large hard structure attached to the trachea is the larynx. These tubes are the ureters. Continue cutting from the anterior end of this cut so that it resembles an upside-down U. The arteries have been filled with red latex and the veins with blue. Played. Both rejection control and urinary excretion system establishment are required to develop fetal kidneys into more mature kidneys in recipients [14]. Be aware that the peritoneum holds the adrenal gland against the kidney; because you have removed the peritoneum, the adrenal will no longer be resting on the kidney but will instead be near the spinal column. The renal artery passes blood from the aorta to the kidney. Figure 39.
