Northern Pintail Research Paper Fall 2015 Jacob A. Keller South Gibson County Northern Pintail Research Paper Fall 2015 The Northern Pintail or Anas acuta as its scientific name states is a dabbling North American waterfowl. The duck is known as one of the most graceful of all the fowl in the Western Hemisphere. This paper shall dive, or rather dabble into the life sustaining habits and delicate structures of the Northern Pintail.
Nowadays thanks to the transgenic techniques, the mouse has become the major animal model used for studying congenital cardiac anomalies and DNA defects induced by chemical substances.(34) C57BL/6 is the most widely used strain produced by a minimum of twenty generations of brother-sister mating.(35) Its genome has been sequenced and they are known as good breeders.(36) Regarding the anatomy of the mouse heart, the thymus gland is well developed and presented anterior to the heart.(37) The heart is surrounded by pericardial membrane which consists of visceral and parietal portions.(37)
The purpose of the Sheep Heart Dissection lab was to take a look at the heart's anatomy and all the parts that it consists of. This lab helped us learn how the heart is able to function, and gave us a hands on look at what a real heart looks and feels like. I worked on this lab with Jose, and Alex. We completed the procedure in one day of class, and had the questions completed by the second.
BIOLOGY REPORT Title: Mammalian heart dissection Name: Lambert Ntashamaje Co-worker ’s Name: Marc Koussi Date of Experiment: 13th January 2017 Words count: 1.Introduction: The aim of this experiment is to observe internal structure of a mammalian heart.
The phenomenon of vein pulsation The venous retinal pulsation is occurring due to the blood pressure difference in the central retinal vein. The pressure difference occurs due to the condition of the systole and diastole pressure. The following are experimental studies carried out so far on physician experiment set-ups and existing theoretical models considered, wave surface with the Pulsations phenomena of collapsible vessels in the body deal.
Introduction: Dissections are performed on preserved animals donated specifically for science education in order to provide a hands-on experience to observe and study anatomy of an animal in three dimension, unlike a textbook, and how the organ systems are interconnected. In this particular dissection a fetal pig was used because the organs present in a pig, and their position in the body are similar to those of humans which provides insight on how human organs systems work overall and why they are essential to life. The purpose of our experiment was to focus on the external, digestive, cardiovascular, respiratory, and excretory systems of the fetal pig to understand how theses system work together in order to sustain life. Materials & Procedure:
The function of the pulmonary artery is to pump deoxygenated blood to the lungs from the heart to become oxygenated. The pressure inside the pulmonary artery is very low, although blood here is at a slightly higher pressure than the blood in the pulmonary vein, and this is reflected as the walls of the artery are significantly thinner than the walls of a corresponding artery, for example, the aorta. The walls of the pulmonary artery contain a large amount of elastic fibres in order to maintain the shape of the artery. The lumen of the artery is smaller than that of the vein which has a large lumen. This relates to the pressure difference between the two blood vessels as the smaller lumen of the artery allows for a greater pressure of blood.
Essay 112: Vitamin K and the Coagulation Cascade The human blood clotting cascade consists of a tightly regulated network of enzymes designed to contain damage to the blood vessels by means of coagulation, thus restoring vascular integrity. Briefly, when a blood vessel suffers penetrating trauma, blunt force trauma, or an internal rupture the clotting cascade swings into action. The various proteins activate one another culminating in the formation of a clot composed of a platelet plug and cross linked strands of fibrin.
Urinary System 1. List the organs of the urinary system by locations and give the basic organ function. (1) The kidneys – The urinary system consists of two kidneys located in the middle of the back with one on each side of the body. This kidneys help to eliminate body wastes through fluid called urine. (2) Two ureters – The ureters connect the kidneys and the urinary bladder.
Assignment 1 – Unit 11 Physiology of Human Body Systems Task 1 The lymphatic system is the system which is involved in homeostasis in our body by draining the interstitial fluid. It is also in charge of defending our bodies from diseases. This is because the lymphatic system provides the place for formation and maturation of the lymphocytes which the white blood cells involved in immunity which are activate when they are in contact with antigens.
Heart, lungs and the Rest of You By: Olivia Abel 1.Explain how the blood flows throughout your lungs, heart and the rest of your body. Heart: Your left and right side of your heart work together to pump blood to and throughout your body which is separated by muscular tissue called the septum. In the right side blood enters through two large vein which are the inferior and superior vena cava, emptying poor oxygen blood from the body to the right reticulum. When the left side enters from the pulmonary veins and empties oxygen rich blood from the lungs into the aorta going throughout the body.
