In the respiratory system you can found nose which is a pathway for air and this is where the oxygen get into the lung and carbon dioxide into the air .Pharynx also known as throat is an other way which air can also enter into the lungs through the mouth. Air also enters into the larynx also known as voice box. It have two main functions as it is a passageway for air to enter into the lungs and a source of vocalization. The epiglottis is a tissue a flap-like cartilage structure contained in…

Filtration (glomerular filtration) in the kidney is the mass movement of water and solutes from plasma to the renal tubule. Filtration takes place in the renal corpuscle specifically with the glomerular capillaries and glomerular capsule. Filtration produces filtrate which is blood minus the cells and proteins. In general, only about 20% of the plasma volume that passes through the glomerulus is filtered. The filtrate then continues through the nephron where…

alcoholic cirrhosis, the portal vein becomes scarred and blocked, causing an excessive increase in hydrostatic pressure. This leads to an increase in capillary hydrostatic pressure. Alcoholic cirrhosis also causes the liver to underproduce albumin proteins. This lowers osmotic pressure in the vasculature, enhancing filtration out of the capillaries. The cumulative effect is fluid leaking and accumulating…

Muscular system: Major functions The muscular system function is that it allows movement of body parts, and works with skeletal system to help us move. Major muscles types : There are many muscles in the muscular system. Some are skeletal, smooth, and cardiac muscle. The skeletal muscle, smooth muscle, and cardiac muscle can stretch and contract, but they complete different functions. The skeletal muscle is attached to your skeleton by strong, springy tendons or is directly connected to rough…

One important allele is the S beta chain responsible for sickle cell anemia, it differs in one amino acid from a normal beta-chain. At the beta gene locus, two possible alleles have two base sequences A = normal beta-chain and S = sickle-cell beta chain. Sickle cell anemia is due to abnormality of hemoglobin, a (protein carrying oxygen to the tissues). “Anemia is a decrease in RBCs; or hemoglobin; or ability to carry oxygen. Hemoglobin S (allele HbS) causes Sickle Cell Anemia, without…

lined with smooth muscle tissue making the bronchioles able to constrict or dilate allowing the amount of air able to move in and pit at the end of the bronchioles the there are air sacs called alveoli where the capillaries meet and gas exchange occurs. At capillaries you have capillary beds which connect the arterioles and the venules. The atrioles play a role in the respiratory system by bringing blood from the heart which has nutrients and oxygen rich blood while the venules are responsible…

The respiratory membrane is made up of a large surface, which is covered by thousands of smaller cell structures known as alveoli. The respiratory surface consists of the alveolar epithelial cells and the pulmonary capillary endothelial cells. However, the wall of an alveolus and capillary creates the respiratory membrane, which is made up of two layers of simple squamous epithelium and their basement membranes (Mid Lands Tech,…

BigDye® Terminator v3.1 Cycle Sequencing Kit provides everything we need in order to generate a sequence all we need to do is add one primer and the DNA template. These reagents are suitable for performing fluorescence-based cycle sequencing reactions on single-stranded or double-stranded DNA templates, on polymerase chain reaction (PCR) fragments, and on large templates. First, you must prepare your template by performing a DNA extraction and purifying your template. The purification will be…

Question 1 Table 1 shows the results for the absorbance values of different concentrations of NaCl, glucose, and tween 20. These solutions were absorbed at 540 nm and 640 nm. Table 2 shows the results of the red blood cells once they were submerged in different concentrations of NaCl and Tween 20. Something is said to be hypo-osmotic if the solution has fewer osmoles per unit volume when mixed with something else (Silverthorn, 2014). The solution in this experiment that was hypo-osmotic…

3. Explain the heart generates and conducts an electrical current. Page 388 The heart has its own built-in conduction system for generating action potentials spontaneously and coordinating contractions during the cardiac cycle. All the cardiac muscle fibers in each region of the heart are electrically linked together. The intercalated disks are connections that electrically join the muscle fibers of the heart into a single unit that can conduct electrical impulses through the entire wall of…
