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.

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:
1 dangerous mutations
Explanation:
Cloning could mutation but it's obvious because to clone you'll have to put something into the person to make every thing realistic.
Answer:
Small head
Explanation:
Since the genes are located in the nucleus of a cell which has being removed (but some genes are still located in the mitochondria of the ocyte) from its ocyte to fuse it with with another nucleus. Since the cell follows a maternal inheritance of gene, it would have a small head because of the presence genes in the mitochondria.
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
To clearly view the morphology of the prokaryotes, one needs a microscope with higher resolution i.e magnification of ×100. Use of oil for this purpose is important because it reduces the refraction of light as it travels from air to glass. this process increases the resolution of the microscope making it possible to view morphology of bacteria.
