Alveoli Nephrons

Alveoli are the tiny air sacs present in the lungs that allows the rapid exchange of gases. Nephrons comprise glomerulus and tubules through which glomerular filtrate passes.

Present in the lungs Present in kidneys

Answer 2

The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.

Alveoli

1. Alveoli are pouch-like air sacs that are made up of simple squamous epithelium.

2. It has a thin cell wall to facilitate gaseous exchange.

3. It is surrounded by blood capillaries.

4. Presence of millions of alveoli in lungs provide ample surface area to facilitate gaseous exchange between air in alveoli and blood in capillaries. Oxygen diffuses across the alveolar and capillary wall into the bloodstream while carbon dioxide diffuses from blood across the mentioned walls into the alveoli.

Nephrons

1. Nephrons are the elongated tubules that form an anatomical and functional unit of the kidney.

2. Each nephron has Bowman's capsule, proximal convoluted tubule, a loop of the nephron, distal convoluted tubule and the collecting ducts.

3. Blood capillaries are present as glomerulus and peritubular capillaries.

4. It serves in fluid and electrolyte balance of the body through the process of urine formation. Each part performs different role in urine formation.
