What Is a macrophage?
- A.
A virus that attacks the blood system
- B.
Type of white blood cell
- C.
An abscess
Correct Answer
B. Type of white blood cellExplanation
A macrophage is a type of white blood cell. White blood cells are an essential part of the immune system and play a crucial role in defending the body against infections and foreign substances. Macrophages are responsible for engulfing and digesting cellular debris, pathogens, and other foreign materials. They are also involved in presenting antigens to other immune cells, regulating inflammation, and promoting tissue repair.Rate this question:

What % of your blood does plasma make up?
- A.
55%
- B.
10%
- C.
90%
Correct Answer
A. 55%Explanation
Plasma is the liquid component of blood that carries various substances, such as nutrients, hormones, and waste products. It makes up about 55% of the total volume of blood. This is because plasma is the largest component of blood and occupies a significant portion of the blood volume, while the remaining 45% is composed of red blood cells, white blood cells, and platelets.Rate this question:

The veins in the upper leg are divided into two groups, what are they?
- A.
Left and right
- B.
Up and down
- C.
Surface and deep
Correct Answer
C. Surface and deepExplanation
The correct answer is surface and deep. The veins in the upper leg are divided into two groups based on their location within the leg. The surface veins are located closer to the skin's surface, while the deep veins are located deeper within the leg, closer to the muscles and bones. This division is important for understanding the anatomy and function of the veins in the upper leg.Rate this question:

What stops the blood from flowing the wrong way round the body?
- A.
Valves in the heart
- B.
The epilglottis
- C.
Peristalsis
Correct Answer
A. Valves in the heartExplanation
Valves in the heart prevent the blood from flowing the wrong way around the body. These valves are located between the chambers of the heart and in the major blood vessels connected to the heart. They open and close to ensure that blood flows in one direction, preventing backflow. This mechanism helps maintain the proper circulation of blood throughout the body, ensuring that oxygenated blood is delivered to the organs and tissues while deoxygenated blood returns to the heart and lungs for oxygenation.Rate this question:

A person of blood type AB could receive a donation from which blood group?
- A.
A+B only
- B.
Any
- C.
A or B
Correct Answer
B. AnyExplanation
A person with blood type AB is considered the universal recipient, meaning they can receive blood from any blood group. This is because blood type AB has both A and B antigens on the surface of their red blood cells, allowing them to accept donations from individuals with blood types A, B, AB, or O. Therefore, the correct answer is "Any."Rate this question:

What is Plasma?
- A.
Liquid part of the blood
- B.
Grey material in the brain
- C.
The fluid in which serm live
Correct Answer
A. Liquid part of the bloodExplanation
Plasma refers to the liquid part of the blood. It is a yellowish fluid that makes up about 55% of the total blood volume. Plasma contains various components such as water, proteins, electrolytes, hormones, and waste products. It plays a crucial role in transporting nutrients, hormones, and waste materials throughout the body. Additionally, plasma also helps in maintaining blood pressure and regulating body temperature.Rate this question:

What happens when you cut yourself?
- A.
Antibodies stop you bleeding
- B.
Blood begins to clot
- C.
White blood cells form a scab
Correct Answer
B. Blood begins to clotExplanation
When you cut yourself, blood begins to clot. This is a natural process that helps to stop the bleeding. Clotting occurs when platelets, a type of blood cell, gather at the site of the injury and form a plug. This plug helps to seal the wound and prevent further blood loss. Additionally, clotting factors in the blood work together to form a fibrin mesh, which strengthens the platelet plug and forms a scab. The scab protects the wound while new skin cells grow underneath.Rate this question:

Which of the following are not a blood group?
- A.
A
- B.
O
- C.
AO
Correct Answer
C. AOExplanation
The blood groups A and O are both valid blood groups. However, AO is not a valid blood group. In blood typing, A and O refer to different antigens present on the surface of red blood cells. AO would imply the presence of both A and O antigens, which is not possible as they are mutually exclusive. Therefore, AO is not a valid blood group.Rate this question:

What chemicals are produced naturally to attack germs?
- A.
Hormones
- B.
Neutrophilis
- C.
Antibodies
Correct Answer
C. AntibodiesExplanation
Antibodies are proteins produced naturally by the immune system to attack and neutralize germs. When the body detects the presence of harmful pathogens, such as bacteria or viruses, it produces antibodies specifically designed to recognize and bind to these invaders. This binding process helps to mark the pathogens for destruction by other immune cells, effectively eliminating the threat. Antibodies play a crucial role in the body's defense against infections and are an essential part of the immune response.Rate this question:

What does blood from the superior vena cava veins drain into?
- A.
Liver
- B.
Heart
- C.
Kidneys
Correct Answer
B. HeartExplanation
The blood from the superior vena cava veins drains into the heart. The superior vena cava is one of the two main veins that brings deoxygenated blood back to the heart from the upper body. It collects blood from the head, neck, arms, and upper chest, and delivers it into the right atrium of the heart. From there, the blood is pumped into the right ventricle and then to the lungs to get oxygenated. Therefore, the correct answer is the heart.Rate this question:

Produce plasma
Correct Answer
B. Destroy harmfull bacteriaExplanation
Lymphocytes are a type of white blood cell that play a crucial role in the immune system. They are responsible for recognizing and destroying harmful bacteria and other pathogens in the body. These cells are part of the adaptive immune response, which means they can specifically target and eliminate specific types of bacteria. Through various mechanisms such as phagocytosis and the release of toxic substances, lymphocytes help to protect the body from infections caused by harmful bacteria.Rate this question:
