Exam 3 Flashcards
What is whole blood
removed blood where the composition is unaltered
what is whole blood separated into
it will separate to plasma at the top and formed elements at the bottom
what is plasma made up of
7% plasma proteins
1% other solutes
92%water
what are the different types of formed elements
- platelets
- white blood cells
what are the white blood cells in formed elemtens?
NEVER LET A MONKEY EAT A BANANA
- neutrophils
- lymphocytes
- monocytes
- eosinophils
- basophils
what are the different proteins made in plasma?
- albumine
- globulins
- fibrinogen
- regulatory proteins
alubmine
major contributions to osmotic pressure
transport lipids, steroid hormones
globulin
transport ions, hormones, lipids
immune function
fibrinogen
essential component of clotting system
can be converted to insoluble fibrin
regulatory proteins
enzymes, proenzymes, hormones
what organ makes up to 90% of the proteins in plasma
liver
what are the different solutes found in plasma?
electrolytes
organic nutrients
organic wastes
electrolytes
normal extracellular fluid ion composition essential for vital cellular activites
contribute to osmotic pressure of body fluids
organic nutrients
used for ATP production, growth and maintenance of cells
organic wastes
carried to sites of breakdown or excretion
what is function of blood
blood is the medium our body uses to carry dissolved gasses, ions, proteins, and nutrients, and wastes throughout the body
general overview of the heart
- The heart is about the size of a clenched fist
- The heart consists of 4 chambers (two atria, two ventricles)
- The heart pumps blood into two circuits (pulmonary and systemic)
- Each circuit involves arteries: carries blood away from heart
- Veins: carries blood to the heart
- Capillaries: vessels that interconnect arteries and veins
- The anterior surface consists of the right atrium, right ventricle, and left ventricle
- The posterior surface consists of the left atrium and a small portion of the right atrium
- The diaphragmatic surface is composed of the right and left ventricles
What is the base and apex of the heart?
The base is the superior border of the heart
The apex is the inferior portion of the heart
What are the two different circuits that carry blood, and where do these circuits carry blood from and too?
Our HEART is the pump that pumps blood throughout two circuits, the pulmonary circuit which pumps deoxygenated blood to the lungs for the exchange of carbon dioxide from the blood to the alveoli, and oxygen from the lungs to the blood. Our systemic circuit is used to carry oxygenated blood to our body tissues.
What is the function of the pericardium, what is the pericardial cavity?
The pericardium shields the heart by reducing external friction and acting as a barrier against extension of infection and malignancy.
Pericardial cavity surrounds the heart
The pericardial cavity is the space between the two serous layers and contains pericardial fluid
What Is the name for the outer and inner layer of the serous pericardium?
An inner visceral layer, also called the epicardium, is attached to the surface of the heart
An outer parietal layer, which is adjacent to the fibrous pericardium
what is pericardial fluid? What is the function of pericardial fluid?
Pericardial fluid lubricates the space to reduce friction
