The atria refers to the chambers in the heart. It is not a type of vein, capillary, or disease. While the heart does have veins and capillaries, they are not specifically referred to as atria.

Correct Answer
C. SystemicExplanation
The correct answer is "Systemic." Systemic circulation refers to the circulation of blood throughout the body, delivering oxygen and nutrients to the tissues and removing waste products. It involves the pumping of oxygenated blood from the left ventricle of the heart to the rest of the body through the arteries, and the return of deoxygenated blood back to the heart through the veins. This type of circulation is essential for maintaining the overall functioning of the body's organs and systems.Rate this question:

Fibrinogen
Correct Answer
B. BloodExplanation
AIDS is a disease caused by the Human Immunodeficiency Virus (HIV), which attacks and weakens the immune system. The virus primarily targets and infects certain cells in the blood, such as CD4+ T cells, which are crucial for the proper functioning of the immune system. As the virus replicates and spreads throughout the body, it progressively destroys these cells, leading to a weakened immune response and making individuals more susceptible to infections and diseases. Therefore, AIDS is a disease of the blood, as it directly affects the blood cells and their ability to fight off infections.Rate this question:

The septum is:
- A.
A wall in your heart
- B.
The upper chamber of your heart
- C.
The lower chamber of your heart
- D.
A blood vessel
Correct Answer
A. A wall in your heartExplanation
The septum is a wall in your heart that separates the left and right sides. It prevents the mixing of oxygenated and deoxygenated blood by dividing the heart into two separate chambers. This ensures that oxygen-rich blood is pumped to the rest of the body while deoxygenated blood is sent to the lungs for oxygenation.Rate this question:
