This is a photo of a monocyte in a blood smear.
These are the largest type of white blood cells, and can be up to 20µm in diameter.
They have a large eccentrically placed nucleus, which is kidney bean shaped.
They have abundant cytoplasm, and some fine pink/purple granules in cytoplasm.
What are the 4 types of blood cells?
It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.
What are the 7 types of blood cells?
In turn, there are three types of WBC—lymphocytes, monocytes, and granulocytes—and three main types of granulocytes (neutrophils, eosinophils, and basophils). See them in action in “Meet the blood cells”.
What are the 3 types of blood cells?
There are three types of living cells in blood: red blood cells (or erythrocytes), white blood cells (or leukocytes) and platelets (or thrombocytes).
What are the 5 types of WBC?
Two pairs of broadest categories classify them either by structure (granulocytes or agranulocytes) or by cell lineage (myeloid cells or lymphoid cells). These broadest categories can be further divided into the five main types: neutrophils, eosinophils, basophils, lymphocytes, and monocytes.
What are the 4 types of cells?
The Four Main Types of Cells
- Epithelial Cells. These cells are tightly attached to one another.
- Nerve Cells. These cells are specialized for communication.
- Muscle Cells. These cells are specialized for contraction.
- Connective Tissue Cells.
What are the 3 types of blood vessels?
What are the three main types of blood vessels?
- Arteries. Arteries carry oxygen-rich blood away from the heart to all of the body’s tissues.
- Capillaries. These are small, thin blood vessels that connect the arteries and the veins.
- Veins.
What are the 5 types of blood cells?
There are five main types of WBCs. They are: Neutrophils, Eosinophils, Basophils, Lymphocytes, and Monocytes. Neutrophils, eosinophils and basophils are also called granulocytes because they have granules in their cells that contain digestive enzymes.
What is the full form of RBC and WBC?
Differences Between Red Blood Cells (RBC) and White Blood Cells (WBC) Red Blood Cells/ Corpuscles (RBC) are also called “Erythrocytes” while White Blood Cells/ Corpuscles (WBC) are also called “Leukocytes”.
Do white blood cells die?
When white blood cells die, they expel necklace-like beads. As white blood cells die, they send out signals to fellow leukocytes nearby—possibly to alert them that they’ve been attacked by a pathogen, and are in the throes of death.
What are the two types of blood?
So, there are eight possible blood types:
- O negative. This blood type doesn’t have A or B markers, and it doesn’t have Rh factor.
- O positive. This blood type doesn’t have A or B markers, but it does have Rh factor.
- A negative.
- A positive.
- B negative.
- B positive.
- AB negative.
- AB positive.
How many platelets are in a drop of normal blood?
A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia. You get your platelet number from a routine blood test called a complete blood count (CBC).
What are the types of red blood cells?
Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. Blood contains many types of cells: white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets.
What kills white blood cells?
A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Cancer or other diseases that damage bone marrow. Autoimmune disorders that destroy white blood cells or bone marrow cells.
What is the largest white blood cell?
monocyte
What is a high WBC count?
A high white blood cell count isn’t a specific disease, but it can indicate another problem, such as infection, stress, inflammation, trauma, allergy, or certain diseases.
What are 3 types of animal cells?
They also carry hormones, enzymes, and vitamins to different parts of the body. Each type of animal cell is specialized to do different jobs. Muscle cells comprise the three different types of muscles: skeletal, cardiac, and smooth types. Each type of animal cell is specialized to do different jobs.
What type of cells do humans have?
Eukaryotic cells make up animals, plants, fungi, and some single-celled organisms. And they have a number of structures inside them, called organelles. The most prominent organelle is the nucleus, which contains the cell’s genetic material, or DNA (see more on DNA).
How many types of human body are there?
The human body contains more than 200 types of cells that can all be classified into four types of tissues: epithelial, connective, muscle, and nervous.
What are the 4 types of blood vessels?
There are various kinds of blood vessels:
- Arteries.
- Elastic arteries.
- Distributing arteries.
- Arterioles.
- Capillaries (the smallest blood vessels)
- Venules.
- Veins. Large collecting vessels, such as the subclavian vein, the jugular vein, the renal vein and the iliac vein.
- Sinusoids.
What are most of our blood vessels?
Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide and waste products to pass to and from the tissue cells.
Which type of blood vessel has the thickest walls?
Structure of blood and blood vessels
| Artery | Vein | |
|---|---|---|
| Wall | Thick, muscular | Thinner |
| Lumen | Small | Large |
| Other features | Thick muscular walls to withstand blood flowing at high pressure as it leaves the heart; the largest artery is the aorta | Contain valves to prevent back flow of blood |

What are rare white blood cells?
White blood cell disorders of neutrophils and lymphocytes are the most common. Disorders that involve monocytes and eosinophils are less common; basophil disorders are rare. Neutropenia is the general term for low numbers of neutrophils in the blood.
What does a high WBC mean?
A high white blood cell count usually indicates: An increased production of white blood cells to fight an infection. A reaction to a drug that increases white blood cell production. A disease of bone marrow, causing abnormally high production of white blood cells.
What are the side effects of low white blood cell count?
The most serious complications of low blood cell counts include:
- Infection. With a low white blood cell count and, in particular, a low level of neutrophils (neutropenia), a type of white blood cell that fights infection, you’re at higher risk of developing an infection.
- Anemia.
- Bleeding.
What do normal blood cells look like?
Under a microscope, normal red blood cells look like doughnuts without holes in the center. Red blood cells contain the iron-rich protein hemoglobin. This gives blood its red color and carries oxygen from the lungs to the rest of the body.
What happens if you don’t produce red blood cells?
Aplastic anemia is a rare but serious blood disorder that occurs when your bone marrow cannot make enough new blood cells for your body to work normally. Many diseases and conditions can damage the stem cells in bone marrow. As a result, the bone marrow makes fewer red blood cells, white blood cells, and platelets.
What should your hemoglobin be?
The normal range for hemoglobin is: For men, 13.5 to 17.5 grams per deciliter. For women, 12.0 to 15.5 grams per deciliter.
