PLENARY DISCUSSION GROUP 14. GROUP MEMBERS: Fatimah Putri Az Zahra Aulia Fash Farabi Utari Gestini Rahmi Mustika Febriani Rizona Fauzul Azhim Mega Gusti Ayu Teddy Kurniawan Vivit Erdina Yunita Sari Mulyani Suresh Mariah. Pity taro…….
This morning, Taro, 16 years complained of abdominal pain and diarrhea for more than ten times since last night. His body felt weak, but Taro felt thirsty, so he kept drinking water. His sister told Taro that not only drinking water, but drinking isotonic drinks so that minerals that come out can also be replaced. Taro also had take anti diarrhea medicine given by her sister.
Although already taking medication and oral rehydration salts, Taro is still suffering from diarrhea, but its frequency has begun to decrease. And unfortunate for Taro, when it would rush to the bathroom because he wants to defecate, Taro slipped, his head banged into the edge of the bath until it wounds and bleeding. Taro cried for help, his sister came and checked the wound in his head. Taro's sister took him to the ICU.
Arriving at the ICU, Taro wound cleaned and stitched, but there is still seeping blood. Taro looked very pale, although the blood that came out a little. Doctors ask about Taro blood type and history of blood clotting disorders. Taro just know his blood type is A, but do not know any history of blood clotting disorders. Taro wounds bandaged and doctors prescribe antibiotics to prevent infection. How do you explain what is experienced by Taro?
Disorders of body fluids
Impaired blood clotting
Lack of platelet
Students are able to explain :
RBCs last an average of 120 days in the bloodstream.
When RBCs age, they are removed by macrophages in the liver and spleen.
A hormone called erythropoietin and low oxygen levels regulate the production of RBCs.
Ninety percent of erythropoietin is made in the kidneys.
When both kidneys are removed, or when kidney failure is present, that person becomes anemic due to lack of erythropoietin.
Most WBCs (neutrophils, eosinophils, basophils and monocytes) are formed in the bone marrow.
Neutrophils are the one of the body's main defenses against bacteria.
Eosinophils kill parasites and have a role in allergic reactions
Basophils are not well understood, but they function in allergic reactions.
Monocytes enter the tissue, where they become larger and turn into macrophages
- Equilibrium static
Where circumstances in which such change is not take place.
- Dynamic equilibrium
Where in a constant state of this system is constantly changing although examples such as a pond at the bottom of the waterfall.
The organism has two environments, namely:
Individuals who have the blood type A, the body will produce antibodies B and will aggulunate the blood that have B antigens .Blood group AB has no antibodies and can receive any type of blood transfusion. Blood group O do not have antigen and can donate to everyone but it must receive the blood from O group only since it have A and B antibodies on it.
Distinguished by antigen-D, E, F is the integral membrane protein in red blood cells. D is a dominant antigen.
- Type: Rh +
Rh-(no antigen D)
2. Platelet plug formation
- When platelets contact with surface vessels are damaged, then the properties of platelets immediately change drastically.
- Platelets swell, its shape becomes irregular with protrusions protruding from its surface, to contract with a strong protein and causes the release of granules containing a variety of active factors, it becomes sticky platelets that attached to collagen fibers, secreting large amounts of ADP, and enzyme-enzyme form thromboxane A 2, which is also secreted into the blood.
Normal blood clotting system in a state of dynamic equilibrium and outlines forming fibrin nets continuously. At this stage, there is decomposition of the net fibrinolysis fibrin by plasmin.
4. The mechanism of blood clotting
(has explained in the previous LO)
5. Connective tissue growth
Is the final process of hemostasis, which will be formed connective tissue, either
permanent or scarring tissue.
- open circulatory system.
- closed circulation system.
3. Components in cardiovascular system is heart,lung, blood and muscle.
4. Is the most important component in the profile of human physiology.
5. Also known as VO2max (defined as the use of oxygen capacity the maximum by the body during the physical conduct activities.
6. Function of the Cardiovascular System is
- deliver oxygen and nutrients to every cell in the body through blood by the heart.- Removing the carbon dioxide and waste products of metabolism from every
cell in the body-Transporting hormones from endocrine glands to target cells via the blood
plasma.- Helping to maintain the temperature in the body.
