Explain the process of life process after respiration to excretion.... How does the oxygenated and deoxygenated blood cycle and in turn how they enter in the Bowman capsule!!...
Explain the process of double circulation from the result of respiration how is it being continued.... please explain in flowchart manner not in paragraph...

Excretion System in Human Beings
Excretory/urinary system consists of :
(1) The kidneys : The excretory organ
(2) The ureters : The ducts which drain out urine from the kidneys
(3) The urinary bladder : The urinary reservoir
(4) The urethra : The channel to the exterior
Excre
(i) The metabolic activities in the body generates many kinds of wastes including nitrogenous wastes which are harmful for the body and hence needed to be removed. Excretion is a process by which these wastes are removed from our body.
(i) Unicellular organisms remove these wastes by simple diffusion.
Excretory wastes
Formation of Urine in Human Beings
Each kidney contains many filtration units called as nephrons.
→ Nephrons are made up of a cluster of thin walled capillaries called glomerulus which is associated with a cup like structure called as Bowman’s capsule and the long tube which terminates through this
capsule.
→ The renal artery brings oxygenated blood to the kidneys along with the nitrogenous wastes like urea and uric acid and many other substances.
→ The blood gets filtered through the glomerulus and this filtrate enters the tubular part of nephron.
→ As this filtrate moves down the tubular part, glucose, amino acids, salts and excess of water gets selectively reabsorbed by the blood vessels surrounding these tubules.
→ The amount of water reabsorbed depends upon :
(i) How much excess of water is there in the body and,
(ii) How much nitrogenous wastes need to be excreted out.
→ So the fluid now flowing in the tubular part is urine which gets collected in collecting ducts of nephrons.
→ These collecting ducts together leave the kidney at a common point by forming the ureter.
→ Each ureter drains the urine in the urinary bladder where it is stored until the pressure of expanded bladder leads to an urge to pass it out through urethra.
→ This bladder is a muscular structure which is under nervous control.
→ 180 litres of filtrate is formed daily but only 2 litres is excreted out as urine so the rest is reabsorbed in the body.
Structure of Nephron
Functions of Nephron
→ Excretion of nitrogenous wastes.
→ To maintain the water and ionic balance (osmic regulation).
Artificial Kidney
Haemodialysis: The process of purifying blood by an artificial kidney. It is meant for kidney failure patients.

what enters the atrium etc.....
Ohh, ok ok just a minute
and how the circulation process further results in excretion
this is my ques
Mechanism Of Double Circulation
Double circulation is the most efficient way of circulation. Here, in humans, the four-chambered heart, arteries, veins, and capillaries all have a vital role to play. Blood gets pumped out of the heart. This blood goes to different organs and then blood again comes back to the heart. All this happens in a very systematic way through the different arteries and veins carrying oxygenated and deoxygenated

The pulmonary circulation or pathway carries the deoxygenated blood from the right side of the heart to the lungs. Exchange of oxygen and carbon dioxide takes place in the lungs and the blood is now oxygenated (with oxygen).
Through the systemic circulation, oxygenated blood travels from the left side of the heart to the other areas of the body. At various organ sites, exchange of gases, nutrients, and waste through lymph occurs. This deoxygenated blood again goes back to the right side of the heart.
The pulmonary circuit and the systemic circuit work together. This ensures that deoxygenated blood goes to the lungs through the pulmonary artery while the oxygenated blood from the aorta reaches the different organs and tissues.
I am unable to send further info
thank u.....but u could not explain the direction of flow
