randomly from either one of these veins. All the deoxygented blood from parts of the body above the heart‚ comes in throught the superior vena cava into the left atrium. Then all the deoxygenated blood from parts of the body below the heart‚ comes from the inferior vena cava into the heart. Once there‚ it is pumped into the right ventricle through a flap called the tricuspid valve. From the right ventricle it goes through the pulmonary valve into the pulmonary artery. From there it goes to the lungs

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body. Energy is the strength and ability that is required in order to perform physical or mental activities. There are different forms of energy these consist of: magnetic‚ kinetic‚ heat‚ light‚ gravitational‚ chemical‚ sound‚ electrical‚ elastic and nuclear. The law‚ conservation of energy states that the total amount of energy within a system remains constant at all times‚ although energy within the system

the body through a series of arteries‚ veins and capillaries. Arteries and capillaries send blood from the heart to all areas of the body‚ while veins help bring that blood back to the heart. Arteries carries oxygenated blood away from the heart‚ and veins carry deoxygenated blood back to the heart. This process is called circulation. The roles are revered in pulmonary circulation. The pulmonary arteries bring deoxygenated blood to your lungs‚ while the pulmonary veins will bring

currently causing some severe damage. Shrunken to a mere eight microns in length‚ our state-of-the-art “mini-submarine” is prepped and ready for injection into the body of this female subject. Our journey will begin in the femoral vein and continue its course through the vein system all of the way to the heart and into the right lung. Buckle up and hold on tight! Keep your arms and legs in the vessel at all times‚ the body works wonders at attacking foreign substances so we can’t be too safe throughout

the popliteal nerve can cause numbness‚ tingling‚ pain‚ and weakness in the lower leg‚ ankle and foot. Vascular injury could cause a bleed from either popliteal artery or vein causing a hematoma or blood pool that could cause significant pain in that area. The main types of injury would include soft tissue‚ muscle‚ nerve‚ and artery/vein‚ ligaments and menisci. A skin and soft tissue injury could include a mild contusion with some redness or bruising. Scratches may occur. If there is a deeper penetration

attached to the heart is the aorta. This carries nutrient filled blood to the rest of the body. 3. What is pulmonary circulation? Pulmonary circulation is the circulation of blood from the heart to the lungs through the pulmonary artery and pulmonary veins. The heart pumps deoxygenated blood from the heart to the lungs and then the blood is sent back being oxygenated‚ where it is then pumped to the rest of the body. 4.
