Answer:

a. True

Explanation:

A portal system begins with a set of capillaries and ends with a set of capillaries. Blood comes from one set of capillaries to a a larger blood vessel which drains into another set of capillaries and it is then sent to the heart.

A classic example of portal system is Hepatic portal system. Major function of this system is to deliver nutrients from digested food to liver so that it can be metabolized.  Small intestine absorbs nutrients from the digested food. These nutrients enter the blood in first capillary bed present in intestine. The deoxygenated blood flows through Hepatic portal vein to liver. Inside liver the blood passes through second capillary bed and nutrients are released in hepatocytes. These capillaries join the hepatic vein and the blood is sent to heart via inferior vena cava.

AlladinOne [14]

Answer:

A. Children report more cognitive symptoms than adults, is true regarding panic disorders in children.

Explanation:

Children with panic disorder are more anxious as compared to adults even when they are not having panic attacks. They report severe cognitive symptoms such as fear of an attack, reluctance to perform well in school, avoiding certain places due to fear of attack called agoraphobia, depression, substance abuse and suicidal behaviors. Hence, children may also need psychotherapy along with panic disorder medications so that they could control their anxiety. Early treatment of panic disorder with cognitive behavioral therapies may prevent complications such as agarophobia, and depression in children.

The correct answer will be option C- endothelial cells of the endocardium.

Explanation:

The pulmonary capillary bed is the network of capillaries in the lungs- alveolar region mainly where gaseous exchange takes place.

FromTheMoon [43]

Change the environment's temperature or move the patient somewhere warmer. Dry off the patient and the bed sheets.

If the temperature is 32.8°C (91°F). External cooling devices or cold normal saline infusions are utilized to quickly reduce body temperature to 89.6° to 93.2° F (32° to 34° C) when therapeutic hypothermia is used postresuscitation.

What is therapeutic hypothermia ?

  • Treatments to lower body temperature include therapeutic hypothermia. This lessens injuries and ongoing issues. It is occasionally applied to patients who experience cardiac arrest. When the heart abruptly stops beating, cardiac arrest occurs.
  • The difficulties brought on by hypothermia are intended to be avoided through induced hypothermia. It is mostly utilized in neonatal encephalopathy, head injuries, and survivors of cardiac arrest who are comatose. The prevention of cerebral reperfusion injury is suggested to be a mediator for the mechanism of action.
