A. In an average, healthy human, the partial pressure of carbon dioxide is usually higher in the body tissues than the systemic arteries.

B. In an average, healthy human, the partial pressure of oxygen is usually higher in the pulmonary arteries than in the body tissues.

C. Generally speaking, gases will diffuse up their pressure gradient

D. In an average, healthy human, the partial pressure of carbon monoxide is usually higher in systemic veins than the alveoli

E. In an average, healthy human, the partial pressure of oxygen is usually higher in the systemic veins than the alveoli

9. Which of the following statements are accurate?

A. The liquid portion of the blood is known as the hematocrit

B. Platelets function in blood clotting

C. Lymphocytes are the only type of white blood cells and are immune cells.

D. Red blood cells are known as erythrocytes

E. Hemoglobin would be found in white blood cells and function in carrying oxygen to the body tissues

Answer 1

8. A.  In an average, healthy human, the partial pressure of carbon dioxide is usually higher in the body tissues than the systemic arteries.

C. C. Generally speaking, gases will diffuse up their pressure gradient.

Partial pressure of CO2 is higher within tissues than in systemic arteries.

Pulmonary arteries have lesser partial. Pressure for oxygen than in body tissues as pulmonary arteries carry de oxygenated blood to lungs for ozygenation.

9.

B. Platelets function in blood clotting

D. Red blood cells are known as erythrocytes.

Liquid portion of blood is not called as haematocrit but it is called as plasma.

Lymphocytes are not the only type of WBCs. Other types of WBCs are neutrophils, basophils. Eosinophils macrophages.

Haemoglobin is found within RBCs and not WBCs.
