Answer: a. Its first capillary beds drain into arterioles.
Explanation:
The kidneys are the two filtering units in the bodies. Inside each kidney their is a filteration unit called as glomerulus. This includes a group of blood vessels called as capillaries. The blood enters the capillaries by afferent arterioles and leaves by the virtue of efferent arterioles.
Answer: This is TRUE for me. Osteoporosis is a preventable disease.
Explanation:
In this condition, bone density ( the amount of bone tissue) is reduced because it's deposition does not keep pace with resorption. Although the bone is adequately mineralised, it is fragile and microscopically abnormal, with loss of internal structure.
Peak bone mass occurs around 35 years and then gradually declines in both sexes. Lowered oestrogen levels after the menopause are associated with a period of accelerated bone loss in women. Thereafter bone density in women is less than in men for any given age. That is why in North America, one-third of all women experience fractures because of this disease, amounting to about 2 million bone fractures per year.
Common features of osteoporosis are:
--> skeletal deformity: gradual loss of height with age, caused by compression of vertebrae.
--> bone pain
--> fractures: especially of the hip ( neck of femur), wrist and vertebrae.
It is TRUE for me that some risk factors can't be changed ( which is the low oestrogen levels that occur after menopause in women) but others, such as poor calcium intake, can.
Exercise and Calcium intake during childhood and adolescence are important in determining eventual bone mass of an individual and in preventing risk of osteoporosis in later life.
Answer: Pathophysiological problem
Explanation:
Pathophysiological problems refers to the study of the adverse changes that occur in the normal physical, mechanical and biochemical functioning of the body. These changes are caused either due to a disease or an abnormal syndrome.
The given situation is an example of the pathophysiological problem. This is due to abnormal changes in the physical, mechanical and biochemical functioning of the body. The physical changes includes the shortness of breath, swollen ankles , three gallops and not being able to sleep in flat position. The increased jugular venous pressure, crackles in the lung, are the example of the mechanical changes in the pathophysiological problem.
The mechanism by which genes are transferred from a donor to a recipient microorganism is called TRANSDUCTION. After transduction, the genetic makeup of the recipient cell is different.
Transduction refers to the genetic recombination mechanism by which bacteria can transfer fragments of DNA by using bacteria-infecting viruses called bacteriophages.
During transduction, a bacterial cell interacts by a conjugal bridge through which fragments of DNA are transferred to a suitable (host) recipient cell.
This mechanism (transduction) changes the genome of the host cells by generating genetic recombinants when the bacteriophages initiate a new cycle of infection.
