Skin, liver, lungs, kidneys, excretion.

One of the following sets of body parts or substances or processed, pick out the one item which overall includes the remaining foir.
Glomerular filtrate, bowman’s capsule, ultrafiltration, glomerulus, blood plasma.

Given below are of five terms. Rewrite the terms in their correct order so as to be in logical sequence.
Renal artery, urethra, ureter, kidney, urinary bladder.

The given diagram represents a nephron and its blood supply. Study the diagram and answer the following question :

Label parts 1, 2, 3 and 4.

Study the diagram given alongside and then answer the question that follow:

Name the parts labelled 1, 2, 3, and 4.

Given below is a highly simplified diagram of the human kidney cut open longitudinally. Answer the question that follow:
Write two differences in composition of the blood flowing through the blood vessels, 'A' and 'B'.

Look at the figure given below. It is a section of human kidney as seen from the front.
Which area/part (give its name and number given on the diagram) which contains the following:
(i) Malpighian capsule
(ii) The pyramids
(iii) Freshly collected urine

Look at the figure given below. It is a section of human kidney as seen from the front.
Name the parts numbered 1-5.

Study the diagram given alongside and then answer the question that follow:

What is the technical term given to the process occurring in 2 and 3? Briefly describe the process.

Given below is the figure of certain organs and associated parts in the human body. Study the same and answer the question that follow:
Name the parts numbered 1 to 5.

Match the terms in Column I with those in Column II and write down the matching pairs

	Column I	Column II
a	Bowman's Capsule	Renal artery
b	Contains more CO2 and less urea	Regulates amount of water excreted
c	Anti-diuretic hormone	Renal Vein
d	Contains more urea	Glomerulus

What is dialysis? Under what condition is it carried out?

Explain the terms ultrafiltration and selective absorption

Diuretic increases the production of urine.

Glomerular filtrate consists of many substances such as water, salts, glucose and white blood corpuscles.

Glomerular filtration is influenced by the hydrostatic pressure in the glomerulus.

Urethra carries urine from the kidney to the urinary bladder.

Urine leaves the urinary bladder of a female by means of the uterus.
