Q

How does blood contribute in homeostasis?

A

transporting
oxygen, carbon dioxide, nutrients, and hormones to and from your body’s cells.

Q

What is the importance of blood and interstitial fluid?

A

They assist in helping multicellular organism that cannot move around to obtain oxygen and nutrients or eliminate carbon dioxide and other wastes.

17
Q

What is blood?
Extra: what is the extra cellular matrix called?

A

Blood is a liquid connective tissue that consists of cells surrounded by a liquid extracellular matrix.
The extracellular matrix = blood plasma: it suspends various cells and cell fragments.

18
Q

What is interstitial fluid? How is it renewed?

A

Interstitial fluid is the fluid that bathes body cells and is constantly renewed by the blood.

19
Q

What is the reverse direction for carbon dioxide to be eliminated?

A

from body cells to interstitial fluid to blood.

20
Q

What does EOP do and where is it produced in the human body?

A

Erythropoietin (EPO) increases the number of red blood cell precursors. EPO is produced by cells in kidneys

21
Q

What is TPO. Where is it produced from?

A

Thrombopoietin (TPO) is a hormone produced by the liver that stimulates the formation of platelets from megakaryocytes.

22
Q

What is hemostasis

A

The process of blood clotting and healing

23
Q

What is the bloods main function in the human body?

A

Transportation

24
Q

What is the average life cycle for RBC

A

120 days

25
Q

What is hypoxia

A

Oxygen deficiency at tissue level

26
Q

What is chemotaxis

A

Inflamed or damaged cells release this chemical to attract phagocytes

27
Q

In hemostasis, there are 3 steps that prevent blood loss. What does this prevent if successful

A

Vascular spasm: arteries and arterioles are damaged; smooth mm of outer walls contract to shrink vessel to reduce blood flow and loss for serveral minutes

platelet plug formation: formation of platelets form a plug

blood clotting: serum makes a blot clot (clotting/ coagulation)
It prevents hemorrhage

28
Q

What blood type is the universal donor

A

O-

29
Q

What blood type can receive from anyone?

A

AB+

30
Q

What is it called when a person has higher than normal levels of RBC

A

Polycythemia

31
Q

These blood cells have a nuclei and full complement of other organnelles but don’t have any hemoglobin

A

WBC / leukocytes

32
Q

Erythropoiesis is the production of RBCs, starts in the red bone marrow.

A

True

33
Q

What is the physiology of RBC

A

Has no nucleus, all internal space is to transport oxygen

34
Q

What is anemia

A

Anemia: lower then normal levels of RBCs
