1

What are the 3 major components of blood?

Plasma, white blood cells, and red blood cells.

2

Label this diagram.

Orange liquid is plasma

Below the plasma is a thin clear layer of white blood cells

The dark red component are red blood cells .

Top - Red circle - Red Blood cell

Middle - Yellow circle - White blood cell 

Bottom - Pinkish bits - Platelets 

 

4

What is blood plasma?

This fluid carries the blood components throughout the body. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it.

5

What is blood serum?

Serum is the liquid that remains after the clotting of blood, therefore contains proteins not used in blood clotting such as electrolytes, antibodies, antigens and hormones

6

What is a major component of blood plasma?

Water 

7

What is serum albumin?

A plasma protein

8

What are immunoglobins? 

Produced by plasma cells (white blood cells). They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction.

9

What are Fibrinogens?

Fibrinogen is a protein produced by the liver. This protein helps stop bleeding by helping blood clots to form

10

What are lipoproteins?

lipoproteins play a key role in the absorption and transport of dietary lipids by the small intestine

11

What are regulator proteins in the blood? 

They regulate clotting factors, cell stimulants, inflammatory proteins, and hormones in the blood. 

12

What are eosinophils? 

Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body's immune response. They can also build up and cause inflammation

13

What is a mast cell? 

A type of white blood cell that is found in connective tissues all through the body,

14

What is a basophil?

In addition to fighting parasitic infections, basophils play a role in: Preventing blood clotting: Basophils contain heparin. This is a naturally occurring blood-thinning substance.

15

What are stem cells? 

Stem cells are cells with the potential to develop into many different types of cells in the body.

16

What are platelets?

Platelets (thrombocytes) are colorless blood cells that help blood clot. Platelets stop bleeding by clumping and forming plugs in blood vessel injuries.

17

What are erythrocytes?

The main job of red blood cells/erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs.

18

What are leukocytes aka white blood cells? 

the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.

19

Label this diagram 

Red circle - Erythrocytes aka red blood cells 

Blue circle - Leukocytes aka white blood cells 

Yellow part - Platelets 

20

What are granulocytes?

white blood cells that help the immune system fight off infection.

21

What are monocytes?

Larger than granulocytes in terms of the unilobar nuclei. 

22

What are lymphocytes?

A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The count of these in our body can tell a doctor whether we are sick or not. 

23

What do T cells do?

T cells (also called T lymphocytes) are one of the major components of the adaptive immune system. Their roles include directly killing infected host cells, activating other immune cells, producing cytokines and regulating the immune response.

24

What do B cells do?

 B-cells fight bacteria and viruses by making Y-shaped proteins called antibodies, which are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells such as T cells 

25

During organ transplants which cells are more likely to reject the new organ? 

T cells 

26

What is oxyhemoglobin?

a bright red substance formed by the combination of haemoglobin with oxygen, present in oxygenated blood.

27

28

What does the Oral cavity do?

The oral cavity represents the first part of the digestive tube. Its primary function is to serve as the entrance of the alimentary tract and to initiate the digestive process by salivation and propulsion of the alimentary bolus into the pharynx

29

What is the function of the pleural membrane?

The function of the pleura is to allow optimal expansion and contraction of the lungs during breathing.

30

What is the function of the intercostal muscles?

the internal intercostal muscles relax and the external intercostal muscles contract, pulling the ribcage upwards and outwards to aid in the respiratory process.
