Plasma is ______% water and ______% dissolved gases, salts, minerals, nutrients, enzymes, hormones, waste, and proteins. 3 basic types of proteins are found in plasma: 1. Albumin - ______ 2. Globins - ______ 3. Fibrinogen - ______ The composition of plasma is regulated by ______.

What is a hematocrit?

• A type of blood test that measures the percentage of red blood cells in the blood

• A type of white blood cell

• A blood clotting factor

• A type of blood plasma protein

Leukocytes and erythrocytes differ in their functions and characteristics. Which of the following best describes this difference?

• Leukocytes are involved in oxygen transport, while erythrocytes are part of the immune system.

• Leukocytes are part of the immune system, while erythrocytes transport oxygen.

• Both leukocytes and erythrocytes are involved in oxygen transport.

• Both leukocytes and erythrocytes are part of the immune system.

Why must oxygen be carried by erythrocytes?

• Oxygen is nonpolar so it can't diffuse into the blood.

• Oxygen is too large to pass through the blood vessel walls.

• Oxygen is reactive and needs to be stabilized by erythrocytes.

• Oxygen is only soluble in plasma when bound to erythrocytes.

• Red and White Blood Cells

• Platelets and Plasma

• Antibodies and Antigens

How common is each type of leukocyte in the blood?

• Neutrophils are the most common, followed by lymphocytes, monocytes, eosinophils, and basophils.

• Lymphocytes are the most common, followed by neutrophils, monocytes, eosinophils, and basophils.

• Monocytes are the most common, followed by neutrophils, lymphocytes, eosinophils, and basophils.

• Eosinophils are the most common, followed by neutrophils, lymphocytes, monocytes, and basophils.

Thrombocytes are also known as:

• Red blood cells

• White blood cells

• Platelets

• Plasma

How do blood cells form? Hematopoiesis is the ________.

• process of blood cell formation

• destruction of blood cells

• clotting of blood

• transport of oxygen
