Compare the functioning of alveoli in lungs and nephrons in kidneys with respect to their structure
and functioning
Answers
Answer:
Explanation:
Alveoli
Alveoli are the tiny air sacs present in lungs that allows rapid exchange of gases.
Present in lungs
There are located in the respiratory system
There are around 480 million alveoli found in each lung
These are sac-like structures
Blood is supplied to pulmonary veins
Facilitates gaseous exchange in lungs
Made up of simple squamous epithelium
Nephrons
Nephrons comprise glomerulus and tubules through which glomerular filtrate passes.
Present in kidneys
These are located in the excretory system
Here re around 1.5 million nephrons found in kidneys
These are tubular structures
Pulmonary arterioles supply blood
Afferent arterioles supply blood
Blood is supplied to renal veins
Facilitates blood filtration to produce urine
Made up of simple cuboidal epithelium with microvilli
