Questions and Answers
- 1.
The ONLY veins that carry oxygenated blood are called the......
- A.
Superior veins
- B.
Blue veins
- C.
Red veins
- D.
Pulmonary veins
- E.
Aortic veins
Correct Answer
D. Pulmonary veinsExplanation
The pulmonary veins are the only veins in the body that carry oxygenated blood. After oxygen is exchanged in the lungs, the pulmonary veins transport the oxygen-rich blood back to the heart to be pumped out to the rest of the body. This is in contrast to other veins, which typically carry deoxygenated blood back to the heart.Rate this question:

The two uppermost (and smallest) chambers of the heart are called?
- A.
Arteries
- B.
Vesicles
- C.
Valves
- D.
Atria or atrium
Correct Answer
D. Atria or atriumExplanation
The two uppermost chambers of the heart are called the atria or atrium. These chambers receive blood returning to the heart from the body and lungs. They then contract to pump this blood into the lower chambers of the heart, known as the ventricles, which then pump the blood out to the rest of the body.Rate this question:

The two main (biggest) chambers of the heart are called?
- A.
Atrium
- B.
Ventricles
- C.
Veins
- D.
Arteries
Correct Answer
B. VentriclesExplanation
The two main chambers of the heart are called ventricles. The ventricles are responsible for pumping blood out of the heart and into the circulatory system. They are the largest chambers of the heart and are located at the bottom of the heart. The right ventricle pumps deoxygenated blood to the lungs to pick up oxygen, while the left ventricle pumps oxygenated blood to the rest of the body.Rate this question:

The muscular, tubular structures that carry oxygenated blood throughout the body are called?
- A.
Veins
- B.
Arteries
- C.
Vesicles
- D.
Ventricles
Correct Answer
B. ArteriesExplanation
Arteries are the correct answer because they are the muscular, tubular structures that carry oxygenated blood throughout the body. Veins, on the other hand, carry deoxygenated blood back to the heart. Vesicles are small, fluid-filled sacs found in cells, and ventricles are the chambers of the heart that pump blood.Rate this question:

A membranous tissue that controls the direction of flow of blood in the heart is called a ___________
Correct Answer
valve
valvesExplanation
The correct answer is "valve, valves." A valve is a membranous tissue that controls the direction of blood flow in the heart. It allows blood to flow in one direction while preventing backflow. Valves are essential for maintaining the proper circulation of blood and ensuring efficient functioning of the heart.Rate this question:

What is the name for the tubular structures that mainly carry deoxygenated blood throughout the body?
Correct Answer
vein
veinsExplanation
Veins are the tubular structures that primarily transport deoxygenated blood throughout the body. They are responsible for carrying blood back to the heart after the oxygen has been delivered to the tissues. Veins have valves that prevent the backward flow of blood and rely on muscle contractions to assist in the movement of blood towards the heart.Rate this question:

What is the name of the colorless and odorless gas that our bodies require to live?
Correct Answer
oxygen
O2Explanation
Oxygen is the name of the colorless and odorless gas that our bodies require to live. It is essential for the process of respiration, where it is used by our cells to produce energy. Oxygen is transported throughout our body via the bloodstream and is necessary for the functioning of all our organs. O2 refers to the molecular formula of oxygen, indicating that it consists of two oxygen atoms bonded together.Rate this question:

What is the main artery of the body?
- A.
Pulmonary vein
- B.
Aorta
- C.
Vena Cava
- D.
Pulmonary arch
Correct Answer
B. AortaExplanation
The main artery of the body is the aorta. It is the largest artery in the body and carries oxygenated blood from the heart to all parts of the body. The aorta originates from the left ventricle of the heart and branches out into smaller arteries to supply oxygen and nutrients to all organs and tissues. It plays a crucial role in maintaining blood circulation and ensuring the delivery of essential substances to the body's cells.Rate this question:
-
- 9.
Blood is pumped from the left atrium to the
- A.
Right ventricle
- B.
Right atrium
- C.
Pulmonary artery
- D.
Left ventricle
Correct Answer
D. Left ventricleExplanation
The left ventricle is responsible for pumping oxygenated blood from the left atrium to the rest of the body. It is the main pumping chamber of the heart and has a thicker muscle wall compared to the other chambers, allowing it to generate enough force to push blood throughout the body's circulatory system. This is why the left ventricle is the correct answer in this case.Rate this question:
-
- 10.
The Left Ventricle pumps blood to the ......
- A.
Right ventricle
- B.
Right atrium
- C.
Pulmonary vein
- D.
Aorta
Correct Answer
D. AortaExplanation
The left ventricle is responsible for pumping oxygenated blood to the rest of the body through the aorta. The aorta is the largest artery in the body and carries the blood from the left ventricle to all the organs and tissues, providing them with the necessary oxygen and nutrients. Therefore, the correct answer is Aorta.Rate this question:

Name the valve that lies between the Right Atrium and Right Ventricle.
- A.
Bicuspid valve
- B.
Tricuspid valve
- C.
Aortic Semilunar valve
- D.
Pulmonary Semilunar valve
- E.
Tubular valve
Correct Answer
B. Tricuspid valveExplanation
The correct answer is the Tricuspid valve. This valve is located between the Right Atrium and Right Ventricle of the heart. It consists of three cusps or flaps that allow blood to flow from the atrium to the ventricle and prevent backflow. The Tricuspid valve ensures that blood flows in one direction, from the atrium to the ventricle, and helps maintain the proper functioning of the heart.Rate this question:

What blood cell is responsible for making blood red?
- A.
Red cells
- B.
White cells
- C.
Platelets
- D.
Plasma
Correct Answer(s)
A. Red cells
D. PlasmaExplanation
Red blood cells, also known as erythrocytes, are responsible for making blood red. They contain a protein called hemoglobin, which binds to oxygen and gives the cells their red color. Plasma, on the other hand, is the liquid component of blood that carries nutrients, hormones, and waste products. Therefore, the correct answer is red cells and plasma.Rate this question:
-

Red blood cells are made where?
- A.
The spleen
- B.
The pancreas
- C.
Bone marrow
- D.
The liver
Correct Answer
C. Bone marrowExplanation
Red blood cells are made in the bone marrow. The bone marrow is a soft, spongy tissue found inside the bones. It is responsible for producing red blood cells, along with other types of blood cells. Red blood cells play a crucial role in carrying oxygen to different parts of the body. The bone marrow contains stem cells that can differentiate into various types of blood cells, including red blood cells. Hence, the bone marrow is the correct answer for where red blood cells are made.Rate this question:

Which blood cells fight infection?
- A.
Red
- B.
White
- C.
Platelets
Correct Answer
B. WhiteExplanation
White blood cells are the blood cells that fight infection. They are part of the body's immune system and help to defend against pathogens such as bacteria, viruses, and fungi. White blood cells are able to recognize and destroy these pathogens, helping to prevent the spread of infection throughout the body. They are an essential component of the body's defense mechanism and play a crucial role in maintaining overall health and well-being.Rate this question:

Which blood cells cause blood to clot and are considered sticky?
- A.
Red
- B.
White
- C.
Platelets
- D.
Plasma
Correct Answer
C. PlateletsExplanation
Platelets are the blood cells that cause blood to clot and are considered sticky. When there is an injury or damage to a blood vessel, platelets gather at the site and form a clot to prevent excessive bleeding. They release chemicals that attract more platelets and help in the formation of a stable clot. Platelets are small, irregularly shaped cells that circulate in the blood and play a crucial role in hemostasis, the process of stopping bleeding.Rate this question:

Oxygen and nutrients are exchanged with the bodies tissues where?
- A.
The arteries
- B.
The venules
- C.
The arterioles
- D.
The capillaries
- E.
The lungs
Correct Answer
D. The capillariesExplanation
Oxygen and nutrients are exchanged with the body's tissues in the capillaries. Capillaries are tiny blood vessels that connect arteries and veins. They have thin walls which allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. This exchange is essential for delivering oxygen and nutrients to the cells and removing waste products from them.Rate this question:
