Brachial artery

P3 – Describe the structure and contraction of different types of muscle. In regards to muscle, there are three main types. These include voluntary (skeletal) muscle, involuntary (smooth) muscle and cardiac muscle. Each have particular functions within the body. One of the main functions which skeletal muscle is responsible for is allowing movement including both fine and gross motor skills to be carried out. Another function which skeletal muscle is required for is protecting an individual’s…

needs to make an access through your blood vessels. They would do this by minor surgery to either your arm or leg. Sometimes they make an access by joining an artery to a vein that is under your skin to make a fistula which is a bigger blood vessel. Other ways include: A graft which is when they use a soft plastic tube to combine an artery and a vein under your skin or they use a catheter which makes an access with a narrow plastic tube and that is then inserted into a large vein in your…

A1: Acute and Chronic inflammation differ in many ways. For example, acute inflammation as blatant as it is, acute inflammation is short, only lasting from a few minutes to days. On the other hand, chronic inflammation, is longer, lasting around days to even years. Furthermore, acute inflammations deal with fluid and plasma oozing. In addition, to leukocytes leaving to the extravascular tissues, which are mainly habited by neutrophils. Chronic inflammation, additionally, is associated with…

one's arteries, the blood vessels that carry oxygen and other nutrients from one's heart to the rest of their body, become thick and stiff; resulting in the occasional restriction of blood flow to their organs and tissues. Symptoms normally do not appear if it is a mild case. A moderate to severe case has different symptoms depending on where the affected arteries are located. When located in the heart arteries one might experience chest pains or chest pressure, but if it is in the arteries…

Contrary to systolic dysfunction, diastolic malfunction is characterized by normal contractility and a typical ejection fraction. The relaxation of ventricles in this disorder is impaired, resulting in an increase in ventricular pressure into the left atrium and pulmonary venous system leading to signs of pulmonary and systemic venous congestion. This decrease in preload results in a decrease in blood volume, especially during periods of increased activity or exercise, when blood is unable to…

In the brain, there are respiratory centers that are the central control of ventilation. They are located within the brainstem and their job is to adjust ventilation when they receive signals of changes in the chemical composition. Changes in the arterial partial pressure of carbon dioxide or oxygen and changes in blood pH have a major effect on ventilation. For example, when the arterial partial pressure of carbon dioxide and blood pH are altered, it sends a message to the respiratory control…

What is a rectal prolapse? Rectal prolapse is a disorder where a part of the rectum projects via the anus. The rectum is the large portion of the digestive system that comes after the colon. It is part of the large intestine or large bowel. There are diverse types of rectal prolapse; some might project through the anus while others pass via the anal canal but not out of the anus. In addition to elderly females being most affected, it also befalls in young kids usually within the first 3 years of…

A patient named RG has ischaemic heart disease with two previous myocardial infarctions (MIs) is admitted to ICU after undergoing coronary artery bypass grafting. After surgery, his preoperative ejection fraction was 45%. He also has controlled hypertension and hypercholesterolaemia. He needs mechanical ventilation and pulmonary artery catheter in place. His blood pressure and urine output have fallen after one hour admission to the ICU. He has no signs of ischaemia, tamponade and acute MI. He…

There are a 11 body systems there is the INTEGUMENTARY SYSTEM which The integumentary system is the organ system that protects the body from various kinds of damage There is also the MUSCULAR SYSTEM The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. There is also the SKELETAL SYSTEM The skeletal system includes all of the bones and joints in the body. Each bone is…

The three basic types of blood vessels, including capillaries, arteries and veins. • Arteries take oxygen-rich blood away from heart. • Veins take blood back toward heart. • Capillaries are very tiny blood vessels that form a connection between arteries and veins. Transfer of nutrients, oxygen and wastes in and out of body facilitated by the capillary. 3. The Blood The heart pumps blood throughout body. The…
