cardiac muscles. Myoglobin is also very effective in assisting the body during the partial pressure points of oxygen at lower intervals. 9. Explain the phases of ventilation during submaximal exercise. There are 3 phases in the ventilation during submaximal exercise. Phase 1- This is the beginning of the exercise. Due to the gas exchange that is occurring, the intensity may cause the individual to increase oxygen consumption. The individual will then reach the level of steady state. Phase 2-…

The urinary system functions to removes wastes from the blood and the kidney is known for filtration and absorbing water. The urinary system consists of a renal corpuscle (glomerulus and bowman’s capsule), a proximal tubule, a loop of Henle, and a distal tubule. The kidney filters about 180 liters and gets rid of about 1.5 liters as urine. Renal clearance is a measurement that analyzes the activity and efficiency of the kidney; it is the volume of plasma need for the kidney to complete remove a…

1. What kind of a history do you need to gather on the geriatric population prior to ordering psychotropic medication? A full and complete Medical history is important to consider any co-morbid disease processes. Has the patient been treated for or diagnosed with any psychiatric disorders or diseases? Has the patient been compliant with treatment for medical or for psychiatric treatment? What type of treatment worked for the patient in the past? The possibility of a medical diagnosis…

The main objective of this study was to determine whether the rate of cavitation in xylem channels correlates with tree height by measuring the water tension from leaves at the top against leaves from the bottom of Acer Platanoides (Norway Maple) trees. We hypothesized that water tension would be higher at the top of trees than at the bottom. The secondary focus was to determine if varying water tension would affect the structural composition of leaves. In order to identify a relationship, we…

they require a higher pressure of a forced exhale. 3. Explain why an individual who exercises regularly has a higher vital capacity. Individuals who exercise regularly, usually have a higher vital capacity because the muscles require more oxygen when they are very active which requires the lungs to take in more oxygen, this is because the diaphragm muscles are increasing in strength. The more regular exercise you do, the more the lungs need to expand in order to take in the extra oxygen that…

Exam on COPD and related factors Please download questions and type answers being sure to cite references. • Define COPD and describe the three major disorder groups including symptoms and diagnostic signs. Chronic Obstructive Pulmonary Disease (COPD) is a group of lung diseases that are characterized by constant obstructed airflow through the lungs and airways. The three disorder groups are: 1. Chronic bronchitis: this is when there is "persistent inflammation and excessive secretions of…

COPD is diagnosed through a series of assessments. A doctor will take into account the signs and symptoms and clinical presentation of the patient, as well as family history and test results. These tests include lung function test such as spirometry.. Other tests that may be used are Chest X-rays, CT scan of the chest and arterial blood gases. These tests, in addition to helping diagnosing COPD, can determine the severity of the disease process. Lung function tests measure how much air you…

detected by the central and peripheral chemoreceptors of the central nervous system. Subsequently, some events require rapid feedback from the respiratory system in order to maintain adequate oxygen levels inside the body. For instance, strenuous exercise increases the demand for oxygen (Widmaier et al, 2015, 44). Overall, the concept of gas exchange, respiration rate, and acid-base balance were applied to the experiments performed during the respiratory lab. These trials involved measuring…

In the article, “Compressive Forces and Computed Topography-derived Positive End-expiratory Pressure in Acute Respiratory Distress Syndrome” (Cressoni et al. 2014), the researchers' hypothesis was that there was a direct correlation between lung recruitability and positive end-expiratory pressure (PEEP). This would validate the prevailing notion that higher PEEP is only for patients with higher lung recruitability. Previous studies have led to advancements in the field such as the switch from…

A 37-year-old primigravida presented at 8 weeks’ gestation with sudden abdominal pain, which lasted for one hour. An initial examination revealed a blood pressure (BP) of 89/54 mmHg with a pulse rate of 82/min. The uterus was of appropriately sized for gestational age without her abdominal muscular defence and the viable foetus was detectable by transvaginal ultrasonography. Her haemoglobin level was 11.2 g/dl. After two hours, her pain progressively worsened and abdominal guarding developed.…
