**RESPIRATORY SYSTEM** HOW DOES AIR ENTER AND EXIT OUR LUNGS? Air enters when the diaphram is lowered due to the movement of muscles. The lower pressure in the chest cavity causes air from the outside to rush into the lungs DIARGRAM OF THE RESPIRATORY SYSTEM   **EXCRETORY SYSTEM**  **CIRCULATORY SYSTEM** Under high pressure, their wall needs to be thick and muscular to cope with the pressure of the blood being pumped from the Heart. || Veins carry blood towards that heart. This blood is not under pressure || The thin walls of the capillaries allow efficient gas exchange. || Pumps blood around the blood ||
 * Name of structure || Role of structure ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Kidney || <span style="font-family: Arial,Helvetica,sans-serif;">The bean shaped kidneys filter waste products out of the bloodstream and depose of them by creating urine. Urine is made up of these waste products dissolved in water 2 kidneys constantly filter blood to produce urine ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Ureter || <span style="font-family: Arial,Helvetica,sans-serif;">This thin tube like structure carries urine from the kidney to the bladder. There are two ureters- one draining each kidney 2 ureters carry urine from the kidneys to the urinary bladder ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Bladder || <span style="font-family: Arial,Helvetica,sans-serif;">The urinary bladder stores urine until it is released from the body . Your bladder is expandable, muscular sac in the lower abdomen stores urine until it is passed from the body through the urethra. ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Urethra || <span style="font-family: Arial,Helvetica,sans-serif;">Is the tube that carries urine from the urinary bladder to the outside of the body. This single tube like structure allows urine to exit the body from the bladder. ||
 * || <span style="font-family: Arial,Helvetica,sans-serif;">Artery || <span style="font-family: Arial,Helvetica,sans-serif;">Vein || <span style="font-family: Arial,Helvetica,sans-serif;">Capillary || <span style="font-family: Arial,Helvetica,sans-serif;">Heart ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Structure || <span style="font-family: Arial,Helvetica,sans-serif;">Thick muscular walls || <span style="font-family: Arial,Helvetica,sans-serif;">Walls of the veins are not as thick as the walls of the arteries. Veins contain valves. || <span style="font-family: Arial,Helvetica,sans-serif;">One cell thick || <span style="font-family: Arial,Helvetica,sans-serif;">A strong muscular organ ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Function || <span style="font-family: Arial,Helvetica,sans-serif;">Since arteries carry blood away from the heart
