A classmate says that without specialized cells, the heart wouldn’t be able to help other organs and body system to perform. Based on your understanding of body organization, is there evidence to support her claim?
(a) Yes, without red blood cells, the heart wouldn’t be able to deliver oxygen to other organs
(b) somewhat, because the heart is constructed from specialized tissues, such as muscle tissue, that help it to function but the cells are no different than other body cells
(c) no, this in inaccurate because it is the brain, not the heart that help the other organs in the body to function
(d) No, because the cells in the heart are not specialized compared with other organs in the body

- As we auscultate the heart it is imperative, we understand what part of the heart we are listening to. Cellular senescence is observed when there is obstruction of the coronary circulation to the muscle tissue of the heart. If the left anterior descending artery (a.k.a. “Widow maker”) is occluded, predict an alternative route of blood flow to the myocardium. Start from the left coronary artery.arrow_forwardplatelets globulins fibrinogen erythrocytes leukocytes connective plasma fibrinogen coagulation albumin men women formed elements Blood is a tissue that consists of formed elements and an extracellular matrix called The formed elements include red and white blood cells, and cell fragments called Plasma: The fibers of the extracellular matrix are actually fiber precursor molecules called Plasma consists of water, protein, nutrients, electrolytes, wastes, hormones, and gases.

- c) A patient has a CT scan of their abdomen with an absorbed dose of 25.0 mGy. The scan ends near the top of their pelvis. Assume that 15% of their bone is scanned, 20% of their skin, 90% of their colon, 25% of their bladder and 10% of their lungs but none of their liver, stomach and gonads. A further 20% of tissue characterised as 'remainder of the body' is also exposed during the scan. The tissue weighting factors for various organs is listed in the table below: Tissue Tissue weighting Tissue Tissue weighting factor factor skin 0.01 oesophagus 0.04 bone marrow 0.12 bladder 0.04 bone surface 0.01 breast 0.12 brain 0.01 gonads 0.08 lung 0.12 thyroid 0.04 liver 0.04 salivary glands 0.01 stomach 0.12 remainder of body 0.12 colon 0.12 What is the overall effective dose received by the patient from the CT scan?arrow_forwardImagine that you are a red blood cell moving through the circulation. After moving into the right atrium, how many heart valveswill you pass through before you first enter the circulation of the lungs? How many heart valves will you pass through beforeentering the circulation of the brain?arrow_forwardChen, a 78-year-old male has a long history of cardiovascular disease. Recently, he has developed “blue lines” bilaterally, distal to the knees. He is worried that this could be a sign of another heart attack or something similar, so he decides to seek treatment. His physician notes that Chen’s right leg has twisted bulging veins that are blue in color. His left leg has lighter-colored blue lines that are not raised from the surface of the skin. Chen reports that his right leg hurts, especially during and after exercise. Chen reports that his father had varicose veins. Chen reports that he is mostly sedentary and spends a lot of time watching TV or playing board/card games. His BMI is 24, BP is 130/78, and pulse is 68. Which of the following statements is true? Varicose veins are common in people under 30 years of age. Varicose veins are common in pregnancy. Men are more likely to develop varicose veins than women.…arrow_forward

- One way to characterise biological tissue is to send a small electrical current through the tissue and measure the opposition to flow of that current through the tissue. In humans, the resistivity of fat is considerably greater than for muscle, which in turn is considerably greater than for blood and other body fluids. This can be used to analyse body composition, in particular, to estimate body fat percentage. (a) Using a simple model of fat versus non-fat tissue, draw a circuit diagram to represent the possible flows of current through the tissue. (b) Why would the analysis of body composition need to take into account the height and weight of the person? (c) How could the level of hydration or electrolyte abnormalities in the person affect the results of the analysis?
