Answer 1

Alveoli and nephron act as the structural and functional units of lungs and kidneys respectively. Alveoli occur in the respiratory system while the nephrons occur in the excretory system. The cell wall of alveoli and nephrons is thick and surrounded by blood capillaries. Let us have a detailed look at the differences between alveoli and nephrons with respect to their structure and function

ALVEOLI

Alveoli are the tiny air sacs present in the lungs that allows the rapid exchange of gases

Present in the lungs

There are located in the respiratory system

There are around 480 million alveoli found in each lung

These are sac-like structures

Pulmonary arterioles supply blood

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

Around 1.5 million nephrons found in kidneys

These are tubular structures

Afferent arterioles supply blood

Blood is supplied to renal veins

Facilitates blood filtration to produce urine

Made up of simple cuboidal epithelium with microvilli

HOPE IT HELPS

THANKS FOR MAKING ME BRAINLIST

Answer 2

congratulations rose

for genius rank rose

u did it very fast

btw gm

hru

have a bangtastic day ahead

Alveoli are the tiny air sacs present in the lungs that allows the rapid exchange of gases.

they are present in lungs

these are sac like structure

it is the site for gaseous state exchange and makes large surface area for gaseous exchange

nephrons are the functional units of kidney

these r the tubular in structure

Made up of simple cuboidal epithelium with microvilli

each kidney consists of 1-1.5 million nephrons

actually i have this concept

this nephron diagram is very important and even heart.

hope it helps you rose

actually I was saying abt my exams yesterday right

yap it's gonna be easy

coz we have only mcqs for the exams

only for this year exams
