After getting into the body of the person, the virus enters into ————-, simultaneously HIV enters into ————-

Options

A. helper T-lymphocytes, macrophages
B. killer T-lymphocytes, monocytes
C. macrophages, helper T-lymphocytes
D. none of the above

Answer

To answer the question, we need to identify the two types of cells that the HIV virus enters after it enters the body.

1. **Step 1: Understanding HIV Entry**
The Human Immunodeficiency Virus (HIV) is known to enter the human body through various means, such as sexual contact, from an infected mother to her child, or through contaminated blood transfusions.

**Hint:** Think about how viruses typically enter the body and which cells they target.

2. **Step 2: Identifying the First Cell Type**
After entering the body, HIV first targets macrophages. Macrophages are a type of immune cell that can engulf and digest pathogens, and they are also known as the "HIV factory" because they can produce a large number of viral particles.

**Hint:** Consider which immune cells are among the first responders to viral infections.

3. **Step 3: Identifying the Second Cell Type**
Simultaneously, HIV also enters helper T cells (also known as CD4+ T cells). These cells are crucial for the immune response, and HIV specifically targets them, leading to a decrease in the immune system's ability to fight infections.

**Hint:** Think about which cells are essential for coordinating the immune response and are affected by HIV.

4. **Final Answer:**
After getting into the body of the person, the virus enters into **macrophages**, simultaneously HIV enters into **helper T cells**.

**Summary of the Answer:**
- First Blank: Macrophages
- Second Blank: Helper T cells
