Unit 10 Reflection

      In this unit we learned about the human body. To this we did labs such as the pig dissection. Our video tutorial on the body parts is attached at the bottom. We learned about the circulatory system and the respiratory system as well as the immune system and lymphatic system. Red blood cells are used to transport carbon dioxide and oxygen. White blood cells use antibodies to fight pathogens. The lymphatic system is a system of tubes and sacs throughout the body that collect waste and blood from tissues. Phagocytosis is a process of swallowing a cell. 

      The vena cava is a large vein carrying deoxygenated blood into the heart. The inferior vena cava carries blood from the lower body and the superior vena cava carries blood from the head, arms, and upper body. The pancreas produces enzymes and hormones that help break down foods. The liver detoxifies chemicals and metabolizes drugs. The spleen acts as a filter for blood as part of the immune system. The ureter carries urine from kidney to the bladder. The coronoary artery supplies blood to the heart muscle. The trachea brings air to the lungs and allows you to breath. The diapragm flexes to allow breathing. The renal artery is a blood vessel that carries oxygenated blood to your kidneys. The aorta is the largest artery in the body. Overall, we learned a lot about the different functions of our body.
