To determine the correct answers to the questions, let's break down each question and its options:
2. Which of the following is responsible for carrying nutrients to and waste from the body’s cells? (1 point)
To answer this question, we need to identify the component or substance in the listed options that carries nutrients to and waste from the body's cells.
- Plasma: Plasma is the liquid portion of blood and mainly consists of water, electrolytes, and proteins. It doesn't directly carry nutrients or waste.
- Red blood cells: Red blood cells, or erythrocytes, transport oxygen to body tissues and remove carbon dioxide waste.
- Red and white blood cells: This option combines the previous two components. While red blood cells transport oxygen and carbon dioxide, white blood cells are primarily involved in the immune response and not specifically in carrying nutrients or waste.
- White blood cells: White blood cells, or leukocytes, play a vital role in the immune response and defending the body against disease. They are not primarily responsible for carrying nutrients or waste.
The correct answer is red blood cells as they carry nutrients and waste to and from the body's cells.
3. _________ defend the body against disease. (1 point)
To answer this question, we need to identify the component or substance that defends the body against disease from the options given.
- Fibrin: Fibrin is a protein involved in blood clotting and not in defending the body against diseases.
- Red blood cells: Red blood cells are responsible for oxygen transport and not for defending against diseases.
- Plasma: Plasma is the liquid portion of blood and does not directly defend against diseases.
- White blood cells: White blood cells are the primary cells responsible for defending the body against diseases.
The correct answer is white blood cells.
4. Which molecule transports oxygen in red blood cells? (1 point)
To answer this question, we need to identify the molecule responsible for oxygen transport in red blood cells.
- Hemoglobin: Hemoglobin is a protein molecule found in red blood cells that binds with oxygen to transport it throughout the body.
- Plasma: Plasma does not play a direct role in oxygen transport.
- Fibrin: Fibrin is involved in blood clotting and does not carry oxygen.
- Platelets: Platelets are involved in blood clotting and not oxygen transport.
The correct answer is hemoglobin.
5. A person with the blood type AB ______________ (1 point)
To answer this question, we need to determine what a person with blood type AB can or cannot do in terms of blood transfusion compatibility.
- Cannot receive blood from a person with any other blood type: Blood type AB individuals can receive blood from any blood type as they have both A and B antigens on their red blood cells and thus do not have antibodies against either A or B blood types.
- Can only receive blood from a person with O blood type: Blood type AB individuals can receive blood from any blood type, including both A and B, as their blood type is compatible with all others.
- Can receive blood from a person with any blood type: This answer correctly states that blood type AB individuals can receive blood from any blood type.
- Can give blood to a person with any blood type: While blood type AB individuals can receive blood from any type, they are only universal plasma donors and not universal red blood cell donors.
The correct answer is "can receive blood from a person with any blood type."
6. Which of the following occurs if a person is given the wrong type of blood during a blood transfusion?
To answer this question, we need to identify the possible consequences of receiving the wrong blood type during a blood transfusion.
- Red blood cells clump: When someone receives the wrong blood type, their immune system may recognize the foreign blood cells as an invader and mount an immune response, leading to a reaction where the red blood cells clump together and may cause blockages in blood vessels.
- Clots form in the blood vessels: While clotting can occur in certain circumstances, it is not the direct consequence of receiving the wrong blood type during a transfusion.
- The person could die: This is a severe consequence that can occur if a person receives the wrong blood type during a transfusion, as it can lead to a potentially fatal reaction known as a transfusion reaction.
- All of the above: This option correctly encompasses all the possible consequences mentioned in the previous answer choices.
The correct answer is "all of the above."
Therefore, the correct answers to the questions are:
2. Red blood cells
3. White blood cells
4. Hemoglobin
5. Can receive blood from a person with any blood type
6. All of the above
Your answers are correct:
2. Red blood cells are responsible for carrying nutrients to and waste from the body's cells.
3. White blood cells defend the body against disease.
4. Hemoglobin transports oxygen in red blood cells.
5. A person with blood type AB can receive blood from a person with any blood type.
6. If a person is given the wrong type of blood during a blood transfusion, all of the above can occur (red blood cells clump, clots form in the blood vessels, and the person could die).
