2.8 The lymphatic system

Today's goals

we will check that you understand 2.7 bloodgroups

You will have an understanding of what our lymphatic system is, and how it functions

I have blood type B can I receive blood from a person with blood type 0?

1. Yes
2. No

Which substance from your blood plays an important part in your immune system?

1. Red blood cells
2. White blood cells
3. Platelets
4. Plasma proteins

you do a blood typing test:
anti-A: clots
anti-B: clots
anti-Rhesus: doesn't clot

1. AB+
2. AB-
3. 0+
4. 0-

Which bloodtype can receive from anyone?

What determines your bloodgroup?

1. The presence of antibodies
2. The presence of antigens
3. The presence of red blood cells
4. The presence of plasma

What is the Rhesus factor?

How do the waste products get collected?

At the transition from artery to capillary a part of the blood gets pushed out of the capillaries because of the high pressure

-> It becomes tissue fluid (dissolved oxygen and nutrients)

-> Also contains carbon dioxide and other waste products, gets partially reabsorbed by the capillaries

About 3 litres of fluid every day

The rest of the tissue fluid flows into the lymphatic vessels

Lymphatic vessel

A bit similar to veins, how do they move the lymph, and where to?

Lymph nodes: purify the lymph (Important for the immunesystem!)

Homework for tomorrow 

make 2.8 

Can you make a question for the quiz next week?
