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.

The correct matches are:
1. Sea level (0 m) - 100%
2. Mid-level elevation (4,500 m) - 57%
3. Peak (8,850 m) - 33%
The level of oxygen in the atmosphere depends a lot on the elevation. The smaller the elevation, the higher the oxygen level, and vice versa, the higher the elevation, the lower the oxygen level. So we have a situation in which the oxygen level is the highest at 0 elevation, or rather at sea level. As we go to higher elevations, let say to around 4,500 m, the oxygen level is significantly dropped, which makes it difficult for breathing. If we go even on higher elevation, like 8,850 m, than the oxygen level will much lower, and a human will need to undergo intense long training and also carry oxygen with him/her in order to survive.
Answer: release oxygen during photosynthesis
use nitrates to make proteins
Explanation:
i just googled it homie
Answer:
Bioluminescence
Explanation:
In the deep oceans, the sea cucumbers and polychaete worms use the bioluminescence for defense against predators and to find or attract prey by glowing so the predator can easily see it's glowing skin.
Answer:
menisci
Explanation:
Some synovial joints such as that of knees have crescent-shaped pads. These pads are made up of fibrocartilage and are present between the articular surfaces of the bones. These cartilaginous pads are attached to the fibrous capsule and are called articular discs or menisci.
The function of the menisci is to serve in shock absorption and minimize the wear and tear of the joint. Meniscus also allows the articulating bony surfaces to fit properly and facilitate an adaptable surface for combined movements. Meniscus serves to distribute the weight over a greater contact surface and thereby makes the joint stable. It also spreads the synovial lubricant across the articular surfaces of the joint.
