-
If one kidney fails, man can live on the other kidney.
-
Pulmonary artery contains deoxygenated blood, i.e., it contains carbon dioxide while pulmonary vein contains oxygenated blood, i.e., it contains oxygen.
-
One kidney is sufficient to filter out the excretory products and dialysis is carried out only in case of failure of both the kidneys.
-
Bowman's capsule.
-
Renal artery carries oxygenated blood along with nitrogenous waste material to the Bowman's capsule.
-
Renal artery enters the kidney while renal veins leave the kidney.
-
To adjust liver in the right side of the abdominal cavity.
-
Renal artery, afferent arterioles, glomerulus, efferent arterioles, secondary capillaries, renal vein.
-
Sphygmomanometer is the instrument which measures blood pressure.
-
Lymph contains much less proteins than plasma because the capillary wall is impermeable to plasma proteins.
