Chapter 10.4
1)
Fibrin is a threadlike protein fibre that forms a network on the wound surface to trap erythrocytes and to close the wound to prevent blood loss.
2)
i)haemophilia
ii)thrombosis
3) 
Haemophilia. It is caused by the lack of certain clotting factors in blood]]> 2021-07-09 07:22:55 UTC https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643083152 https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643085071 1) Right lymphatic duct and thoracic duct

2) Both contain plasma without the plasma proteins, erythrocytes and platelets. For the differences, lymph has higher content of fat and fat-soluble substances while tissue fluid has low content of fat and fat-soluble substances

3) Lymph nodes/Spleen/Thymus gland/Bone marrow/Tonsils/Appendix

4) The neccesities of the lymphatic system are acting as the body defence and complements the blood cilculatory system.

5) -Small diameter of capillaries
-The pumping force of the heart

6) -Ensure the lymph flows continuously to the heart.
-Prevent the lymph from flowing back.]]> 2021-07-09 07:24:41 UTC https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643085071 https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643085719 3/3

1) Blood group O and AB.
 
2) The blood of the recipient will react by producing the Rhesus antibody.

3) The blood will agglutinate. It is because the recipient type of blood is O and the antibody in his blood serum is Anti-A and Anti-B. That's make he can't receive blood from any other type of blood.]]> 2021-07-09 07:27:48 UTC https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643088102 https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643090991 1.Adam Faris

2. Name the main heart pacemaker and the node that is located below it. 

3. What does the term myogenic means?

4. Write the number from 1 to 4 for the pumping mechanism of heart:

a) Electrical impulses spread rapidly
in both the atria, causing the atria
to contract simultaneously. The
contraction of the atria helps to pump
blood into the ventricles. (       )
b) The electrical impulses spread
from the apex of the heart to the
whole ventricle wall. As a result, the
ventricles contract to pump blood out
to the lungs and body. (       )
c) The electrical impulses reach the
atrioventricular node. The electrical
impulses spread through the bundle of
His, and the Purkinje fibres up to the
apex of the heart. (      )
d) SA generates electricle impulse. (       )

5. Explain why a person who
stands too long may faint.

6. In what circumstances would
fingers turn pale?]]> 2021-07-09 07:34:52 UTC https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643094565 https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643100120 1. The pacemaker is a group of specific heart contraction and is located at the right atrium wall

2. Sinotrial node and Atrioventricular node

3. The heart contracts and relaxes without receiving any impulse signal from the nervous system

4. 2,4,3,1

5.The blood flow back to the heart requires the
contraction of skeletal muscles around the veins. If
someone stands on his/her feet for too long, less
oxygen flows to the brain, hence less oxygen and
glucose are transported to the brain. This causes
the individual to pass out.

6.When the blood flow is obstructed from flowing to
the fingertips or when the blood vessels contract
due to coldness.]]> 2021-07-09 07:41:33 UTC https://padlet.com/g18140922/5oywbqg47p45bm8d/wish/1643100120
