Let me work through this blood worksheet step by step.
Functions of blood components:
1.
Red blood cells (erythrocytes): These carry oxygen from the lungs to all parts of the body and bring carbon dioxide back to the lungs to be breathed out. They contain hemoglobin which binds to oxygen.
2.
White blood cells (leukocytes): These fight infections and diseases. They are part of the immune system and help protect the body from bacteria, viruses, and other harmful germs.
3.
Platelets (thrombocytes): These help blood clot when you get a cut or injury. They stick together at the wound site to stop bleeding and form a scab.
4.
Plasma: This is the liquid part of blood (about 55% of blood volume). It carries blood cells, nutrients, hormones, waste products, and proteins throughout the body.
Where blood components are made:
- Red blood cells, white blood cells, and platelets are made in the
bone marrow (the soft tissue inside bones).
- Plasma is made in the
liver. The liver produces most of the plasma proteins.
What is hemoglobin?
Hemoglobin is a protein found in red blood cells that carries oxygen. It contains iron and gives blood its red color. Hemoglobin picks up oxygen in the lungs and releases it to tissues throughout the body.
The 8 different blood types:
The 8 blood types are:
1. A positive (A+)
2. A negative (A-)
3. B positive (B+)
4. B negative (B-)
5. AB positive (AB+)
6. AB negative (AB-)
7. O positive (O+)
8. O negative (O-)
Final Answer:
red blood cells: Carry oxygen from the lungs to the body and bring carbon dioxide back to the lungs
white blood cells: Fight infections and diseases; protect the body from germs
platelets: Help blood clot to stop bleeding when injured
plasma: Liquid part of blood that carries cells, nutrients, hormones, and waste throughout the body
Where are the red and white blood cells, and the platelets made? In the bone marrow
Where is plasma made? In the liver
What is hemoglobin? A protein in red blood cells that carries oxygen and contains iron
There are 8 different blood types: A+, A-, B+, B-, AB+, AB-, O+, O-
