Q

describe composition of plasma

A

91% water and 9% salts,
solutes help maintain osmotic pressure
(salts act as a buffer)

Q

how do RBCs transport oxygen and carbon dioxide

A

RBCs are specialized for oxygen transport, they contain protein (hemoglobin) and will bind to oxygen and iron groups

Q

structure of RBC how its well suited for gas transport

A

no nucleus, shape allows them to squeeze through small capillaries and maximize surface area

16
Q

structure and function: Monocytes

A

comes from monoblasts
becomes a large phagocyte

17
Q

structure and function: Eosinophils

A

comes from myeloblasts
contains granules
active in allergies and worm infections

18
Q

structure and function: Basophils

A

comes from myeloblasts
contains granules
releases histamine

19
Q

relationship of leukemia and white blood cells

A

leukemia begins in bone marrow, where while blood cells are produced. and impacts body’s immune response and overall health

20
Q

blood clotting relating to homeostasis

A

preventing absurd blood loss, response to injury, systemic regulation,

21
Q

steps of formation of a blood clot

A

1) blood vessel is punctured
2) platelets congregate and form plug
3) platelets and damaged tissue cells release prothrombin activator, which initiates a cascade of enzyme reactions
4) Fibrin threads form and trap RBCs

22
Q

disorders associated with blood clotting

A

Thrombocytopenia- too few platelets

Thromboembolism- when thrombus (stationary clot), forms, travels (embolism) and plugs other vessel

Hemophilia A and B- genetic deficiencies of a clotting factor

23
Q

components of blood involved in forming a blood clot

A

platelets, clotting factors, Fibrinogen

24
Q

stages of blood clotting

A

stages of blood clotting work in concert to prevent excessive bleeding and facilitate healing.

25
what determines blood types in humans
proteins w/ carbohydrates attached pm the surface of RBCs
26
summarize role of Rh factor in hemolytic disease of a newborn
blood cells can leak from fetus into mother causing mother to get sick
27
list 4 types of blood
A, B, AB, O
28
who can a donor with type blood A donate to?
type A and AB
29
how does the cardiovascular system interact with other body systems to maintain homeostasis
works with all other organ systems to maintain bodys needs
30
how does the cardiovascular system maintain homeostasis
interstitial fluid originates from blood plasma and is absorbed by lymphatic capillaries, becoming lymph
