The surgical procedure. A total knee replacement is a surgical procedure where the diseased knee joint is completely replaced by artificial materials that resemble the original knee joint. The orthopedic surgeon removed the end of the femur and the end of the tibia by using metal pieces and sawing the bone, to ensure that he removes the right amount of bone. The end of the femur bone is replaced with metal and the end of the tibia bone is replaced with plastic and metal. A plastic piece was added under the patella because the surface under the patella was damaged as well. These artificial materials, called prosthesis, have smooth surfaces so when they rub against each other, it does not cause damage and is pain-free. The purpose of this surgery is to remove the diseased portions of the joint and replace it with artificial materials to prevent further deterioration and eliminate pain, stiffness, and decreases in function that were caused by the osteoarthritis.

Experiment Results Predict Question: Predict Question 1: Make a prediction about the basal metabolic rate (BMR) of the remaining rats compared with the BMR of the normal rat you just measured. Your answer : b. The hypophysectomized (Hypox) rat's BMR will be higher than the normal rat's BMR. Predict Question 2: What do you think will happen after you inject thyroxine into the three rats? Your answer : c. The hypophysectomized rat will become hyperthryoidic and develop a goiter. Predict Question 3: What do you think will happen after you inject TSH into the three rats? Your answer : a. The normal rat will become hyperthyroidic and develop a goiter. Predict Question 4: Propylthiouracil (PTU) is a drug that inhibits the production of thyroxine

A joint is a junction of two or more bones and is commonly referred to as an articulation.Without joint in the body no movement will be possible.There are three types of joints immovable/fibrous where no movements are possible(example- cranium).Slightly movable/cartilaginous joint is a joint

In biology, we learn a lot of information that we can use later on in life, no matter what field of study we go into. During this course, we learned about biochemistry, metabolic processes, homeostasis, molecular genetics and population dynamics. Throughout the learning process, we’ve had many questions or INTUS, which we use to expand our knowledge later on and determine the answers to those specific questions. The point of this assignment is to relate questions that we have developed on our particular topic we chose; to these five units we studied in biology.

The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive.

The following muscles need to be stretched, lack of flexibility in which group causes the most injuries

P4: Explain the physiology of two named body systems in relation to energy metabolism in the body

The Mets started playing baseball in April 13, 1962 the Mets played in new york City from 1880 to 1887. The meaning of Mets is Metabolic Equivalent.Met is the term used to represent the intensity of exercise The meaning of mets is Metabolic Equivalent.Met is the term used to represent the intensity of exercise

The Basal Metabolic Rate is essentially a measure of the required amount of energy needed to maintain bodily function while at rest. The most significant requirements that BMR energy needs meet are in processes such as establishing and maintaining a normal breathing pattern, heartbeat, blood circulation and temperature. The primary factors influencing BMR include age, gender, muscle composition, hormonal levels, exercise levels and many more. It is important to recognize that an individual’s BMR is not static and many of the above factors can affect the utilization of energy either positively or negatively. For example, men on average have higher BMRs when compared to women simply due to an increased amount of muscle mass. While it may seem

I would like to first begin by saying a person’s metabolic rate depends on how much thyroxine is produced in the thyroid. Also, there are two types of metabolism, anabolism and catabolism. “Anabolism turns smaller molecules into large molecules, such as fat, protein, and carbohydrates. Catabolism is the process of breaking down fat, protein, and carbs for energy” (newhealthadvisor.com). The pancreas plays a key role in determining how much glucose was consumed and therefore if insulin should be released for anabolism. So the pancreas is the deciding factor on whether or not metabolism will be anabolic or catabolic. All chemical reactions in the body are categorized as metabolism. To be able to perform metabolism, the body needs an adequate supply of oxygen and nutrients.

The type of joint that is chronically affected is the synovial joint. The bones that are at a synovial joint are covered by articular cartilage; which reduces friction and absorbs shock. The space between the articulating bones is

The most common indication for total knee replacement is osteoarthritis, or degenerative joint disease. The end stage of osteoarthritis is wearing out of cartilage (smooth, gliding bone ends) resulting in bone-to-bone contact in diseased joints. It is progressive and becomes increasingly painful as the cartilage erodes. Younger people who get knee replacements have damaged their joints by trauma (accidents that destroy joint surfaces), infection, cancer or tumor, and inflammatory conditions such as rheumatoid arthritis.

(While some of the following muscles act upon more than one joint, the only actions that will be listed are those pertaining to the knee.)

It is a joint disease and commonly the leading cause of pain in older adults. With osteoarthritis, joint cartilage becomes rough and worn. The damaged tissue causes the cells to release an enzyme which contributes to breakdown the cartilage. Inflammation is present in synovium, the lining of the joint. Overtime, the space in the joint becomes narrower. Patient with osteoarthritis experience joint stiffness and pain with weight bearing and movement. As the disease progresses, pain becomes extremely severe (VanMeter & Hubert, 2014 p 175). This the reason why patient had left knee arthroplasty. In left knee arthroplasty, the femoral and tibia component of the knee are replaced with an artificial material called prosthesis to relieve pain and allow a person to restore performance of activities of daily living (LeMone et.al, 2014 p 1356). According to Shmerling (2014), the patient’s risk for developing blood clots increases after surgery. Clots can form inside the blood vessels and this is where it becomes dangerous. Blood clots in the veins will hinder or block the return of blood to the vital organs of the body such as the heart. Due to the patient’s inactivity the flow of her blood becomes sluggish and causes the blood to pool commonly at the lower part of the body such as the leg and could lead to a clot. This is often called as Deep vein thrombosis. There is a tendency, that this clot could travel in the body and lodge in other

Basil Metabolic Rate otherwise known as, BMR, is the equation used to determine the amount of calories that a human should eat to keep their weight constant. This calculation can be utilized to help a person gain or lose weight. I was trying to lose weight during this trial period since my pants have been starting to feel tight recently and I have picked up weight since I got back to college. This equation is not perfect as everyone is not biologically the same and people have different metabolisms. Also, someone who is moderately active may be more or less active during a certain time period than they normally are which may result in skewed results.
