The right option is Tuberculosis
Tuberculosis is a contagious, airborne
disease of the lungs caused by the bacterium; Mycobacterium tuberculosis. The
bacteria is released from the lungs into the air when an infected person sneezes,
spits, or cough and this makes the disease highly contagious as it can be easily
transmitted to others.
Answer:
Nephron-- Collecting Tubule-Collecting Duct- Papillary duct- minor Calyx- Major Calyx- Renal Pelvis- Ureters- Bladder- Urethra
Explanation:
Nephron is a basic unit of kidney,in which urine is formed through the process of filtration (it occurs in glomerulus of the nephron). Nephrons are connected with the collecting duct system of the kidney to a minor calyx. The collecting duct system consists of connecting tubule, medullary collecting duct and papillary duct. The whole collecting duct system has a role in reabsorption and excretion.
Papillary ducts open at minor calyx, later in major calyx. Calyces open in pelvis , which is located inside hilum of kidney. Ureters travel out of kidney through hilum and pour urine into the urinary bladder. Urethra is a tube with the role to tranport the urine from the bladder when the bladder is full.

I think the answer is A, blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling. The main function of the valves in veins is to prevent back flow of blood. Blood in the arteries, after being pumped by the heart, are under much higher pressure than blood in veins so there is no need for arteries to prevent back flow. However, within the veins especially those of legs are valves for the above function, therefore damaged valves would cause some back flow of blood, causing swelling of the legs.
