Question

some points about alveoli and nephron

Answer 1

Both the alveoli and the nephron are vital function areas of the human body. The main difference is that the alveoli are the main functional units of the lungs while the nephron is the main unit of the kidney. The Alveoli are that air sacs where carbon dioxide and oxygen are exchanged and transported. Inside the unit of the alveoli, you can find tissues that create the hormones, enzymes and other pulmonary surfactant. On the other hand, the nephron acts as that unit that maintains concentration of water in the human blood that regulates its production, blood pressure level and acidity. Eventually, the unit will act as the filter for human wastes and urine. If the alveoli act as the filter for air, the nephron acts as that system that will filter the blood, absorbs nutrients and excretes water and wastes.

In its structure, the alveoli appear as that two-tiered unit that comes with elastic fibers and capillaries that round off to a basket description. The capillaries of the alveoli extend outward from the main pulmonary artery and vein. These branches act as that source that will push blood that is either oxygen filled or oxygen depleted to the heart or to the lungs. Meanwhile, the nephron appears with both the renal corpuscle and renal tubule. These two main structures assist in the cleansing and filtering of the blood that will be transported to various parts of the body. The renal corpuscle is the primary portion that filters the blood and the renal tubule will act as that system that will reabsorb the nutrients into the body.

Answer 2

✌️✌️ HEYA MATE HERE IS YOUR ANSWER ✌️✌️
Alveoli :-
They are tiny balloon like structures present inside the lungs.
The walls of Alveoli are one cell thick and contains an extensive network of blood capillaries.
The exchange of oxygen and carbon dioxide takes place between the blood of the capillaries that surround the Alveoli and the gases present in alveoli.

Nephrons :-
They are tubular structures present inside kidneys.
They are made up of glomerulus, bowman's capsule and a long renal tube.
The blood enters the kidneys through the renal artery, the blood is entered here and the nitrogeneous waste in the firm of urine is collected by collecting duct.
