Transcript of EXCRETORY SYSTEM OF THE FROG AND HUMANTHE URINARY SYSTEM IS RESPONSIBLE FOR THE ELIMINATION OF WASTS VIA THE URINE. THE BASIC UNIT OF FUNCTION IS THE NEPHRON COMPOSED OF THE GLOMERULUS AND A SERIES OF TUBULES RESPONSIBLE FOR THE EXCRETION OF WASTES, REABSORPTION OF VALUABLE SUBSTANCES, AND FILTRATION OF BLOOD.

EACH KIDNEY CONTAINS UP TO 18 LOBULES AND THOSE 18 LOBES CONTAINS NEPHRONS ARE THE FUNCTIONAL UNIT OF THE KIDNEYS AND EACH KIDNEY CONTAINS MORE THAN 1 MILLION NEPHRONS. IN THE NEPHRONS COMPOSED OF GLOMERULUS FILTERS THE BLOOD LEAVING THE FILTRATE INSIDE THE GLOMERULAR SPACE. THE FILTRATE HAS SIMILAR CHARACTERISTICS TO PLASMA EPT IN THE PRESENCE OF PROTEINS IN THE FORM OF ALBUMIN. THE FILTRATE THEN GOES INTO THE PROXIMAL CONVOLUTED TUBULES WHERE MAJORITY OF THE SUBTANCES ARE REABSORBED.
KIDNEY
THE FLUID ENTERS THE DESCEDING LIMB OF HENLE WHERE IT IS IMPERMEABLE TO MINERALS AND OTHER SUBTANCES. THEREFORE, THE FLUID INSIDE THE TUBULES BECOMES HYPERTONIC COMPARED TO PLASMA. AS THE FLUID INSIDE GOES UP INTO THICK ASCENDING LIMB OF HENLE, WATER BECOMES IMPERMEABLE. THUS, IT IS ONE OF THE IMPORTANT DILUTING SEGMENTS OF THE URINARY SYSTEM. THERE IS ACTIVE TRANSPORT OF VARIOUS PHYSIOLOGICALLY IMPORTANT IONS SUCH AS POTASSIUM IONS, SODIUM IONS AND OTHERS.

LIQUID WASTE GENERATED BY THE KIDNEYS TRAVELS THROUGH THE MESONEPHRIC DUCT INTO E CLOACA. SOLID WASTE FROM THE LARGE INTESTINE PASSES INTO THE CLOACA. BOTH SOLID AND LIQUID WASTE MATERIALS LEAVE THE BODY THROUGH THE ANUS, THE ONLY OPENING FOUND IN THE POSTERIOR PART OF THE BODY.
THE FLUID THEN GOES INTO THE THIN ASCENDING LOOP OF HENLE AND INTO THE DISTAL CONVOLUTED TUBULE WHERE WATER AND SODIUM REABSORPTION IS EFFECTED BY ALDOSTERONE SECRETION BY THE ADRENAL CORTEX. THE FLUID THEN GOES IONTO COLLECTING TUBULES WHERE WATER REABSORPTION IS AFFECTED BY ADH.SOME REABSORPTION OF IMPORTANT IONS STILL OCCURS IN THESE FINAL SEGMENTS.
THE NEPRON
FINALLY, THE URINE DRAINS INTO THE MINOR AND MAJOR CALYX TO GO INTO THE RENAL PELVIS. FROM HERE IT IS DRAINED BY THE URETER TO BE TEMPORARILY STORED IN THE BLADDER WHERE PERIODIC EMPTYING OCCURS VIA THE URETHRA THROUGH THE PROCESS OF URINATION. THE URETHRA CONNECTS THE URINARY BLADDER TO THE GENITALS FOR THE REMOVAL OF URIE OUT OF THE BODY.

Answer:
Following are the correctly rank steps:
1. The binding of glucose takes place with the transporter on one side of the membrane.
2. The binding of glucose leads to a conformational change, which opens the site of binding on the contrary side of the membrane.
3. The dissociation of glucose takes place.
4. The transporter moves back to the beginning conformation.

Hope this helps plz hit the crown :D
A)codominance that's when you see two colors, spotted or striped.
Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as <u>Phagocytosis</u>
<u>Explanation:</u>
Phagocytosis that is the name given to the process of ingestion of foreign particles by macrophages. In human body the white blood cells does this function. Macrophages is found in all the tissues. Any foreign particle entering the body is engulfed by this process hence protecting the organisms.
Once a bacteria enters the body it is at once detected and recognised as the foreign particle. Then it is attached to the phagocyte. Then it is engulfed into a vesicle called phagosome. Then this is killed by the process of phagocytosis.
