1. Discuss the
in detail. Add a note on blood transfusion reactions.
glomerular filtration rate
and mention its normal value. Explain the factors regulating glomerular filtration rate. (1+1+8=10)
Short notes: (7x5=35)
4. Transport of carbon dioxide
5. Pregnancy test
7. Hormones secreted by the anterior pituitary gland
8. Functions of bile
Answer briefly: (10x2=20)
10. Visual receptors
12. Functions of cell membrane
Functions of Cerebellum
16. Vital capacity
Vital capacity is the greatest volume of air that can be expelled from the lungs after taking the deepest possible breath.
Vital capacity measured by a wet or regular spirometer.
In combination with other physiological measurements, the vital capacity can help make a diagnosis of underlying lung disease.
Vital capacity used to determine the severity of respiratory muscle involvement in neuromuscular disease
It can guide treatment decisions in Guillain–Barré syndrome and myasthenic crisis.
Residual volume is the amount of air that remains in lungs after fully exhaling.
Tests to measure residual volume check how well the lungs are functioning.
Residual volume is measured by: A gas dilution test.
Question No. 10
A photoreceptor cell or visual receptor is a specialized type of cell found in the retina that is capable of visual phototransduction.
They convert light (visible electromagnetic radiation) into signals that can stimulate biological processes.
Photoreceptor proteins in the cell absorb photons, triggering a change in the cell's membrane potential.
Three types of photoreceptor cells : rods, cones, and photosensitive retinal ganglion cells.
The rods are narrower than the cones and distributed differently across the retina, but the chemical process in each that supports phototransduction is similar.
The third is the photosensitive ganglion cells. These cells do not contribute to sight directly, but support circadian rhythms and pupillary reflex.
Question No. 12
The basic function of the cell membrane is to protect the cell from its surroundings.
It consists of the lipid bilayer with embedded proteins.
The cell membrane is selectively permeable to ions and organic molecules
It controls the movement of substances in and out of cells.
