Match each term or structure listed with its correct description.

Answer 1

Answer:

A few of these were missing the term corresponding to the description, so I added them.

2. Polymorphonuclear cell.  - k. neutrophil.

3. Antibody.  - g. reacts with a membrane molecule.

4. Granular leukocyte.  - f. contains cytoplasmic granules.

5. Type A blood.  h. has A antigens and anti-B antibodies.

6. Rh-positive blood.  - c. has Rh antigen.

7. Hemoglobin.  - d. carries blood gases in RBCs.

8. Antigen.  - b. molecule on erythrocyte surface.

e. lacks Rh antigen.  - Rh-negative blood.

i. has B antigens and anti-A antibodies.  - Type B blood.

a. eosinophil.  - j. white blood cell.

Explanation:

Blood is a very important component of our bodies and can be divided into: plasma -the liquid part of the blood- and formed elements -that consist of the cells found in the blood-.

Blood cells have very different tasks, all equally important for this tissue to function and for our bodies to remain healthy.

Erythrocytes, also called red blood cells, are the cells that carry oxygen from our lungs to our tissues, and carbon dioxide from our tissues to our lungs. Besides this fundamental role in gas exchange, erythrocytes also play a big role in acid-base equilibrium and also present specific molecules in their membranes called antigens. These antigens give blood "an identity" and are what determine our blood type, meaning that they are important for recognizing if a cell or a substance is foreign.

Leukocytes, also called white blood cells, are in charge of defending the body from potential threats, such as bacteria or viruses. Leukocytes can be divided into two groups regarding the presence or absence of cytoplasmic granules: granular leukocytes (neutrophils, eosinophils, and basophils) and agranular leukocytes (monocytes and lymphocytes). These granules contain enzymes that are used to reduce inflammation and destroy cells. Each and every one of the different types of white blood cells has specific ways of working and are more effective when attacking a certain type of pathogen.

Platelets, also known as thrombocytes, are the smallest blood cells and they participate in maintaining hemostasis, preventing us from bleeding too much when an injury occurs.
