Description
Q / W h y Independent Activity Unit # 4 Lesson 6 _ d 1. What is the function of the umbilical cord? o The umbilical cord is a flexible cord-like structure, which connects the fetus pig (at e s the naval) with the placenta. The placenta is a pancake-shaped organ that is _ attached to the inside of the mother's uterus. The umbilical cord contains arteries t and veins which deliver nutrient rich blood, and oxygen to the baby. The umbilical cord also removes carbon dioxide, along with any other wastes that the baby pig h produces while in the womb. Without this cord, the baby could not survive. e _ t 2. State the function of the following organs: stomach, liver, r small intestine, gall bladder, pancreas, large intestine, a and spleen. c h Stomach– responsible for storing food and prepares for digestion Liver– metabolizes many drugs (including alcohol) and makes a substance similar e to a detergent for the digestion of fat called bile _ Small Intestine– the first part of the small intestine is duodenum, it is a major h location for food digestion; the second and third part are called the jejunum and a v ileum, here further digestion occurs and nutrients are absorbed e Gall bladder– collects bile, which is sent to the initial portion of the small intestine _ (duodenum) via the cystic and common bile ducts Pancreas– pancreas makes digestive enzymes, which are carried by the pancreatic c duct to the duodenum. The pancreas also makes the hormone insulin, which a promotes sugar uptake from blood r Large intestine– the large intestine reabsorbs water from digested food and the t i remaining undigested material is sent to the rectum l Spleen– involved with maturation and processing of immune cells that protect the a body. Spleen filters blood, removes old or damaged platelets and red blood cells, stores blood, and forms some types of white blood cells g e _ 3. What is the function of the mesentery? r Mesentery are thin sheets of tissue that hold the small intestine in place; it holds i mainly the jejunum and ileum. A large number of blood vessels are present within n the mesentery which nourish the small intestine by providing it with a blood supply. g If the mesentery was not present, the small intestine could kink up, or fold up and s cause a blockage of food, similar to a bend in a water hose. # i 4. Why does the left ventricle contain more muscle than the x right ventricle? z The right ventricle only pumps deoxygenated blood to the lungs through the z 1 pulmonary arteries. Whereas, the left ventricle pumps oxygenated blood to the d entire body via the aorta. The entire body is very large when compared to just the lungs. Not only does the left ventricle pump larger amo
