Answer:
c. creates a high osmotic pressure in the medulla
Explanation:
Loop of henle is a nephron the runs from proximal to distal convulated tubule. It create in the medulla an area of high urea concentration using energy to create the concentration gradients. Henle of loop is divided into four compartment.
1. thin ascending limb of loop of henle- it is highly permeable to water
2. thin decending limb of loop of henle is not permeable to water but Ion
3. ascending limb of loop- reabsorbtion of calcium, sodium and potassium ion from urine takes place here
4.Cortical thick ascending limb- It drains urine into distal convulated tubule.
Answer:
the answere is Bilateral symmetery
Explanation:
Deoxygenated blood enters the right atrium passes through the right ventricle and then goes the lungs through the pulmonary artery.
It becomes oxygenated and enters the left atrium through the pulmonary vein
