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:
ASC-US and ASCUS
Explanation:
The typical squamous cells has significance in the most common abnormal finding in Pap test . It could be the infection sign with some types of human papillomavirus ( HPV ) . The sign of a benign growth , such as a cyst , low level of hormones or in menopausal women .
Test like the HPV test are also required . This is called called as ASC-US and ASCUS .
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.
