...It has been found out that smoking tobacco can cause damage to cellular pathways in the lungs. This damage to cellular pathways can lead to impaired lung function. This can lead to disease in the lungs, like chronic obstructive pulmonary disorder or lung cancer. One of the functions of the lungs that can be impaired is ciliary function. The lungs have to be able to keep participles from accumulating in the lungs, this happens through ciliary function. Cilia will beat to bring trapped participles out of the lungs. In diseases caused from smoking tobacco, it has been found that the ciliary function has been impaired. The cilia become paralyzed and cannot beat participles out of the lungs (Lab Manual for Lab 3 and 4). In this lab the function...

When your lab report is complete, submit this document to your instructor in your assignment box. 1. Endocrine System Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism? Answer 1: Insulin and Glucagon work in tandem to keep the glucose levels in the blood within the normal range. If someone if experiencing high blood sugar levels, the pancreas will begin to secrete insulin by way of the beta cells. As this is happening the liver will take up the glucose and store it as glycogen. Now in the reverse, if a person is suffering from hypoglycemia and has low blood sugar, the alpha cells located inside of the pancreas will begin to produce glucagon. This substance will be sent to the liver and begins the process of converting glucagon to glucose. 2. Cardiovascular System Blood flows through the body in two distinct pathways: the pulmonary pathway and the systemic pathway. The blood flowing in the pulmonary pathway is deoxygenated, and it delivers this blood to the lungs to be oxygenated again. The blood flowing in the systemic pathway leaves the lungs full of oxygen and...

When your lab report is complete, submit this document to your instructor in your assignment box. 1. Endocrine System Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism? Answer 1: “Insulin and glucagon work together to keep glucose levels in the blood within the normal range. When there is an elevated blood glucose level, this stimulates beta cells in the pancreas to secrete insulin. The insulin facilitates the uptake of glucose by body cells, and the liver will uptake the glucose and store it as glycogen. These actions return blood glucose levels back to normal. When there is decreased blood glucose, this stimulates the alpha cells in the pancreas to produce glucagon. The glucagon travels to the liver and facilitates the conversion of glycogen to glucose. This glucose is released in the bloodstream to return levels back to normal.” (M.U.S.E.) 2. Cardiovascular System Blood flows through the body in two distinct pathways: the pulmonary pathway...

...The Mammalian Circulatory and Gas Exchange Systems Radwa Abdallah Professor Yan Xu Fundamentals of Biology II Lab February 20, 2014 Objectives The objectives of the Circulatory System laboratory experiment included observing and learning to identify the structural characteristics, mostly arteries and veins, in the chest cavity of the fetal pig, which would further the understanding of the heart and lungs in most other mammals; another objective was to understand blood pressure and heart rate and the factors that affect it. The objectives of the Gas Exchange laboratory experiment was to observe the respiratory system in the fetal pigs, thus gaining an understanding of the respiratory system in most other mammals; another objective from the portion of the experiment that included measuring the respiratory volumes of humans and understanding the capacity of the human lung. Introduction There are two kinds of circulatory systems, an opened circulatory system and a closed circulatory system. The circulatory system is made up of an internal body fluid that is either hemolymph or blood, a pump system, and a vascular system that is made up of tubular vessels that move fluid from one location to another quickly(Dolphin 377). Hemolymph is the fluid found in the open circulatory system and blood is the fluid found in closed systems. In open circulatory systems the fluid leaves the heart through the arteries and returns through open sinuses rather than veins (379)...

...Heart Dissection I. Purpose The purpose of this lab was to practice dissection skills and to further our knowledge of the heart. From this lab we learnt about the parts and functions of the heart. For example, the different chambers, the veins, and the arteries that all run through the heart. Through careful observation we were able to identify all of the main parts of the heart that keep blood pumping through our body and were able to determine the important structures. Because of this lab I can successfully label a diagram and explain the use for each part of the heart. II. Procedure a. Materials i. Sheep Heart ii. Scalpel iii. Dissection Pan iv. Dissection Pins v. Tweezers vi. Gloves… (If you remember) vii. Camera for Pictures b. Procedure Because sheep hearts are so cheap and readily available, they are the most common use for this type of experiment. We began the lab by observing the external anatomy. We first observed that the heart did not have a pericardium. The pericardium is the body’s way of protecting the heart and separates it from the rest of the thoracic cavity. If it were present we would have cut it away to reveal the white lumpy tissue. The white lumpy tissue is fat tissue. The bulk of the heart tissue is the reddish brown muscle or myocardium. We placed the heart down showing the ventral side to reveal the following features: Apex, Superior Vena Cava, Inferior...

A heart is a muscular organ that pumps oxygenated blood throughout the body using the circulatory system. There me up to four chambers (as in mammals) which contain two atriums and two ventricles. A sheep being a mammal includes these qualities. A sheep's heart is made up of four chambers a left and right atrium, which are located in the upper chambers, are known as the receiving chambers, which receives deoxygenated blood. The lower...

...Asthma What is Asthma? Asthma is an incurable lung disease in which the airways of the lungs swell and narrow making it difficult to breathe (National Institutes of Health, 2011). Symptoms of Asthma include: • Shortness of breathe • Tightness in the chest • Coughing • Wheezing Causes The exact cause of Asthma is still undetermined but researchers believe genetic and environmental factors may play an important role in the diagnosis (Mayo Clinic, 2011). Some of those factors are: • An inherited predisposition to have allergies • The parents have Asthma • Mother smoked while pregnant • Exposure to airborne allergens or viral infections while the immune system is still developing • Being overweight • Low birth weight A person living with Asthma can function normally; they do not experience symptoms on a daily basis. Although daily activities are not compromised in any way, people with Asthma must be aware of conditions that can cause the airways to narrow and swell (Mayo clinic, 2011). Some things that can trigger Asthma symptoms are: • Allergens from dust, mold, pollen, etc. • Irritants like cigarette smoke and chemicals such as cleaning products • Physical activity • Respiratory infections like colds Diagnosis Asthma is diagnosed by a primary care doctor and the diagnosis is based on family history, medical history, a physical exam, and test results (National Institutes of Health, 2011). The tests commonly used to diagnose Asthma...
