Answer:
Primary active transport
Explanation:
Active transport may be defined as the movement of particles against their concentration gradient with the help of an energy source like ATP. Two main types of active transport are secondary active transport and primary active transport.
Primary active transport includes the sodium potassium pump because it directly uses the stored chemical energy in the form of ATP. Three sodium moves out of the cell and two potassium moves inside the cell with the help of ATP.
Thus, the correct answer is option (a).
Answer:
Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
Explanation:
Answer:
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.
This bed receives blood from the pulmonary arteriole which arises from the pulmonary artery. The blood is pumped to this artery through the right ventricle of the heart. The right ventricle- especially the valves is lined from with the endocardium which lines it and prevents the blood from sticking to the inside of the chamber.
Therefore, the blood pumped from the right ventricle is in contact with the endothelial cells of the endocardium and option C is the correct answer.
PAD is physical aid in dying. It is also known as assisted /uicide.
Oncology is the study of cancer. And a cancer specialist is referred to as an oncologist. Many times patients with severe medical conditions want to end their life. This is done with help of a physician. This is referred to as physician aid in /ying (PAD). Cancer has gained a lot of attention from PAD. The oncologist should before taking any step should consider that the patient has access to palliative options and it should be maintained that they have adequate counseling. PDA is becoming legal in the United States of America.
Whether physicians stand in support of PDA or they consider it an unethical practice, they must have a framework within which to accept and process a patient’s request for physician aid in /ying.
