Answer: Option B. "False"

Explanation:

Nephron can be defined as the functional unit of the kidney.

Descending limb and ascending limb are the combinly called loop of nephron or henle and are the part of renal tubule in the nephron.

Descending limbs and ascending limbs have different permeabilities to water and salt that causes high osmolarity in the Medulla.

The thin descending limb is having high permeability to water as they have low permeability to ions and urea while the thick ascending limb has impermeablity to water as there is active reabsorption of ions.

Hence, the correct option is B.

Chronic alcohol abuse will not only cause an individual to develop liver damage, but may also lead to cerebellar damage. Damage

aleksandrvk [35]

Damage to the cerebellum will cause the individual to appear clumsy and uncoordinated.

<h3>What happens if the cerebellum is damaged?</h3>

The coordination of voluntary motor action, balance and equilibrium, and muscle tone are all functions of the cerebellum. It is situated toward the rear of the brain, just above the brain stem. Compared to the frontal and temporal lobes and the brain stem, it is relatively trauma-resistant.

Slow and uncoordinated motions are the outcome of cerebellar damage. When walking, people with cerebellar abnormalities frequently sway and stumble.

A cerebellar injury can cause the following symptoms:

loss of coordination of motor movement (asynergia)
inability to judge distance and when to stop (dysmetria)
inability to perform rapid alternating movements (adiadochokinesia)
movement tremors (intention tremor)
staggering, wide-based walking (ataxic gait)
tendency to fall
weak muscles (hypotonia)
slur (nystagmus)

Aminiotic fluid formation and clearance ?

stich3 [128]

Introduction :-)

The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus.

Importance :-)

It helps to protect the fetus from trauma to the maternal abdomen.
It cushions the umbilical cord from compression between the fetus and uterus.
It has antibacterial properties that provide some protection from infection.
It serves as a reservoir of fluid and nutrients for the fetus.

Formation :-)

Amniotic fluid is present from the formation of the gestational sac. Amniotic fluid is in the amniotic sac. It is generated from maternal plasma, and passes through the fetal membranes by osmotic and hydrostatic forces. When fetal kidneys begin to function around week 16, fetal urine also contributes to the fluid. In earlier times, it was believed that the amniotic fluid was composed entirely of fetal urine.

The fluid is absorbed through the fetal tissue and skin. After 22 to 25 week of pregnancy, fraternization of an embryo's skin occurs. When this process completes around the 25th week, the fluid is primarily absorbed by the fetal gut for the remainder of gestation.

Contents :-)

At first, amniotic fluid is mainly water with electrolytes, but by about the 12-14th week the liquid also contains proteins, carbohydrates, lipids and phospholipids, and urea, all of which aid in the growth of the fetus.

Hope its helpful :-)

If so, please mark me as brainlist :-)

The pancreas releases alkaline, enzyme-rich pancreatic juice into the ____________ of the small intestine. What is the function

grin007 [14]

Answer:

The correct answer is the duodenum.

Explanation:

Pancreatic juice is an alkaline fluid which contains important enzymes for the digestion of proteins, carbohydrates and fats.

Pancreatic juice is secreted by the pancreas when food enters the stomach which is released into the "duodenum" of the small intestine. The pancreatic juice enters duodenum through a pancreatic duct which joins with the bile duct coming from the liver and form "ampulla of Vater" in the duodenum.

Pancreatic juice helps in digestion of carbohydrates, proteins and fats as it contains pro-enzymes and enzymes like trypsinogen, chymotrypsinogen, lipase and many more. It also makes the acidic stomach solution alkaline due to the presence of HCO₃.

Thus, the duodenum is the correct answer.
