In the lungs the pleural membrane facilitates breathing. The bronchioles end in microscopic alveoli lined by a thin‚ moist epithelium. The alveoli is the primary site of gas exchange. Branches of the pulmonary arteries send oxygen poor blood to the alveoli; branches of the pulmonary veins transport oxygen rich blood from the alveoli back to the heart. Inspiration (the process of inhaling) begins as the external intercostals and diaphragm contract. When this happens‚ the lungs expand. After this

What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and take blood away‚ etc... Veins from the systemic circuit bring deoxygenated blood back to the heart‚ while veins from the pulmonary circuit bring oxygenated blood from the lungs

left). The right atrium receives deoxygenated blood from the body via the superior and inferior vena cava. The right ventricle receives blood from the right atrium and pumps it to the lungs via the pulmonary artery. The left atrium receives oxygenated blood from the lungs via four pulmonary veins. The left ventricle is the largest and most muscular chamber. It receives oxygenated blood from the lungs via the left atrium and pumps blood into the systemic circulation via the aorta. Valves: There

pulmonary artery. This is the only artery that carries deoxygenated blood. The pulmonary artery was quite thin and rubbery and would then have split into two tubes‚ the left and right arteries. These arteries then carry blood to the lungs. We could not see the split in the arteries during the dissection but we did find the pulmonary valve which comprised of three semi lunar cusps. This valve prevents the backflow of blood into the right ventricle. We then discovered the two pulmonary veins‚ these veins

In medical terms when an individual is tapped on patellar tendon (area below the knee cap) using a reflex hammer‚ it causes a sudden movement in the lower leg (like kicking movement). This happens due to the stretch in quadriceps muscle spindle that transmit the signal to the spinal cord especially to the lumbar segment L3 and this send
