Answer: d. none of the above
Explanation:
The respiratory membrane is the membrane which separates the air inside the alveoli from the pulmonary capillaries. The types of respiratory membranes includes the alveoli membrane, the capillary membrane and the basement membrane. The respiratory membrane is usually very thin. But it becomes thick due to the increase in the fluid content, which actually forces the gases to diffuse through the membrane and the fluid. Also the pulmonary diseases can also cause the membrane to become thick.
Answer:
Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells.

Answer: HDLs are antiatherogenic lipoproteins....
Explanation:
The anti-atherogenic effect of HDL occurs, above all, because of its properties to carry lipids, mainly cholesterol esters from peripheral tissues to the liver, which is known as reverse cholesterol transport(RCT). However, other protective actions of HDL, in addition to RCT, have been described in several experimental models and epidemiological studies. These actions include antioxidant protection, mediation of cholesterol efflux, inhibition of the expression of cell adhesion, leukocyte activation, regulation of blood coagulation and platelet activity.

Answer: 1. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
2. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
3.Within the bone marrow, all blood cells originate from a single type of unspecialized cell called a stem cell. When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell.
4. Epinephrine and norepinephrine, hormones secreted by the adrenal medulla, raise blood pressure by increasing heart rate and the contractility of the heart muscles and by causing vasoconstriction of arteries and veins. These hormones are secreted as part of the fight‐or‐flight response.
